Thank you. Hello, everyone. It's great to be with you today. Let me begin by saying that today this company is better positioned than it ever has been on almost every possible measure. As I look back at our progress over the last few years, Inseego is a very different company in a much stronger position. This is illustrated in our first quarter results compared to last year. We reported a 120% increase in our combined 5G and software as a service revenue over last year and gross margins over 35%, up over 400 basis points. We ended the first quarter with approximately $60 million in cash on our balance sheet and zero bank debt. There are four predominant reasons for our remarkable transformation. First, we have greatly reduced our customer concentration by expanding our 4G and 5G carrier customer base in the U.S. and increasingly in international markets.
Second, our rapidly growing software business is yielding recurring higher margin revenue on top of device revenue, which contributed to our strong gross margins this quarter. Third, carrier customers are embracing our recently launched 5G fixed wireless access products, and we see fixed wireless access as a major growth driver for the company going forward. Fourth, our first enterprise 5G fixed wireless products were launched and sold this quarter in North America, EMEA, and Asia-Pacific. As we entered 2021, we had just announced the biggest win in company history with the launch of our 5G MiFi hotspot at T-Mobile, which has quickly become our highest volume 5G customer. T-Mobile has also adopted our Inseego Managed software platform, which adds recurring subscription revenue to those hotspot sales. We are making solid progress in international markets with some initial 5G customer deployments with more to come.
We continue with testing, regulatory approvals, and customer contracts in multiple regions. While it's taking a little longer to establish business in new regions, we see international markets as an important growth driver. The most important development in the last six months has been our 5G fixed wireless access portfolio, and the great news is that every customer dialogue now includes fixed wireless in addition to our hotspots. It is key for mobile operators to create new revenue streams to generate a return on their capital investment in acquiring spectrum and building national networks. It's not only relevant for consumer home broadband and entertainment, but also in the enterprise and private network space. We believe both are very large market opportunities with a wide range of use cases.
I'm very pleased to report that T-Mobile has certified three of our fixed wireless access products for their enterprise business, and we're working closely with them to support customer engagements. This is central to our 5G enterprise initiative announced late last year, and it goes far beyond the work from home market. 5G enables new technologies for the enterprise, such as edge AI and edge computing. We have existing 4G customers such as Dell, VMware, and other enterprise technology leaders, and all of our dialogues with them now include our 5G product lineup. You've seen recent announcements of our new enterprise products and channel partners in North America, EMEA, and Asia-Pacific with more to come. Now let's turn to our new Software as a Service offering.
Almost every conversation we have with carriers and enterprise customers involves our software platforms, which enable them to onboard, manage, and secure the growing number of 4G and 5G devices on their network through centralized cloud management. Our SaaS business has grown significantly over the last 12 months, representing a healthy 24% of our revenue in the first quarter. Our 4G business continues to be strong and we continue to add new customers. We saw a surge in demand for our 4G products starting in March of last year, with the pandemic driving the need for work from home solutions. That helped us win AT&T as a 4G customer, which means our products are now being sold by all of the largest U.S. carriers. While 4G is down from 2020 levels, we are seeing higher demand levels than we did pre-pandemic.
The bottom line is 4G will remain an important part of our business, and it's key as we continue to land and expand 4G customers to 5G. We have positioned Inseego as a pure play 5G company. All our efforts are aligned on the global 5G opportunity. This led us to divest our Ctrack fleet tracking business in South Africa, which is not a target 5G market for us. In addition to reducing our headcount by over 540 people, or 53% overall, the divestiture will increase revenue per employee to over $600,000 on a pro forma 2020 basis. We think this is an important financial metric for the investment community to know. I want to address the global semiconductor shortage. Our business has not been impacted thus far, thanks to our deep and long-standing direct relationships with key component suppliers, in addition to our manufacturing partners.
Through our proactive approach, we have avoided delay in customer deliveries. We expect the current conditions will extend through the end of this year and likely into 2022. Our leadership team will continue to work closely with our silicon partners and take necessary actions to secure supply. With that, I will hand off to Ashish, who will go into further detail on our incredible momentum in 5G and cloud solutions and some groundbreaking customer use cases. Ashish?
Thank you, Dan. Over the past year, our customers have relied on our innovation to accelerate broadband adoption through our state-of-the-art 4G, 5G, and cloud solutions while protecting the end users from security threats. From my numerous conversations with customers, it is clear that our 5G technology, along with our cloud innovations, will form a powerful engine for their business transformation growth as their technology needs continue to evolve at a rapid pace. From a product revenue perspective, we saw strength in our 5G mobile broadband portfolio and Inseego Managed Cloud portfolio, which now accounts for 20% and 24% of our overall business, respectively. This combined 44% is up 2x from a year ago. The mobile broadband business continues to build up, and we're experiencing great reception of our M2000 and M2100 5G solutions from all customers.
The consistent feedback we are receiving from our carrier customers is that our technology is far superior to any other similarly categorized product in the market. We secured another 5G operator, Sunrise in Switzerland, the commercial launch planned for early June. We also just launched the MiFi 8000 in Canada with Rogers and Fido. Many new carrier customers in international markets are trialing our 5G solutions. We anticipate new launches in the coming months. Moving to 5G FWA, we just released a series of new Wavemaker products focused in both carrier and enterprise markets, including two indoor FWA products, FG2000 and an FX2000, and a rugged outdoor product, the FW2000. These products are certified for use in many different regions globally and have recently been certified for use on the T-Mobile network. This is a major accomplishment for Inseego.
Our focus now is on implementing joint go-to-market strategies to maximize our success in this very early market. In addition, on the enterprise side, I'm happy to report that we have generated our first Wavemaker revenue by shipping units to North America, Australia, and Europe. This was accomplished through our growing list of channel partners such as ScanSource, Ingram Micro, SYNNEX in North America, Powertec in Australia, and Sphinx, Solid State Supplies, and others in Europe. In terms of our enterprise market push, we are seeing some exciting use cases even at this early stage of 5G deployments. Let me provide some examples of customer projects we are working on. In the area of traffic, transportation, and logistics, a global leader in transport solutions is deploying our 5G CPE on lampposts in the U.K. to support video streaming.
They are starting with traffic monitoring, but ultimately, the goal is to support autonomous vehicles. A smart city in Georgia, Peachtree Corners, is deploying our 5G solutions on streetlights and other locations where fiber would not be economically feasible to enable smart traffic control, management of autonomous vehicles, and other use cases. A global leader in package delivery is looking at connecting remote hubs and depots in rural areas where cellular reception can be greatly improved with our high-gain products. Our solutions enable many retail use cases as well. Net4 Limited, a system integrator in Europe, is connecting a video feed through our 5G solutions in conjunction with their AI platform. The objective is to provide a solution for retail stores to monitor shelf stock, spillage, theft surveillance, etc . In the U.S., a leading retail chain is trialing Wavemaker as a connectivity solution for vaccine distribution locations.
We're also seeing opportunities in the private network space. A government agency is evaluating Wavemaker for secure private networks. One particular use case for them is deploying secure networks in remote areas where cellular coverage is limited. The transformation of our business to more software and subscriptions continues to show great progress as we achieved 11.5% quarter-over-quarter growth in subscriptions. We saw five consecutive quarters of over 40% growth in our recurring software revenue, excluding Ctrack. Dan mentioned earlier, AT&T now carries the MiFi 8000, but it is important to note that it will also make Inseego Connect available for enterprise customers. We are seeing this in almost all of our customer dialogues that the technological capabilities of our devices, coupled with our software management layer, is a powerful combination.
It is examples like this that give us confidence that we will continue to grow software beyond its current 24% of total revenue. Let me conclude with some thoughts on our product portfolio vision. Access to corporate data anywhere and everywhere securely has become the beating heart of the new enterprise. Our 5G and cloud platforms are built with extensive reach, massive scale, and multiple layers of security to help drive this digital transformation. We're excited about our position in the market. We are executing and innovating with speed. I'm so proud of what our 5G and cloud teams have achieved. Now I'd like to turn the call over to Bob.
Thanks, Ashish. First off, let me say how happy I am to be here on the call with you today. Given today is my one-month anniversary, I've not had the opportunity to speak with many of you, let me start off the call by introducing myself and offering why I was attracted to join Inseego. I have over 25 years of experience as a senior executive, including being the Chief Financial Officer at growth software, cloud, and technology companies, and specifically public companies such as Apogee Enterprises, Lawson Software, and TriZetto. I was brought on by the board of Inseego as Interim Chief Financial Officer with a mandate to support the company's transition to a high-growth 5G and SaaS company. I would like to now review the results of our first quarter of fiscal 2021. Q1 revenue was $57.6 million, up about 1.5% from Q1 of 2020.
We should recall Q1 2020 benefited from the onset of the COVID demand surge, which began in the final weeks of the quarter. The favorable year-over-year comparison is largely due to growth in 5G and software revenue, as Dan and Ashish highlighted. The sequential decline results from a lower level of the surge demand for 4G hotspots, albeit they are running at higher levels than the pre-pandemic activity. First quarter IoT and mobile solutions revenue was $43 million, up 1.3% year-over-year, and down 40% from $72.1 million in Q4. Inseego subscriptions were up 11.5% sequentially and up 175.7% year-over-year, which helped drive the growth versus the prior year. Sell-through of 5G hotspots continues to be strong, and we expect an increase in new shipments in coming quarters as units ordered harmonized with the ongoing demand.
Enterprise SaaS revenue for Q1 was $14.6 million, up 4.8% quarter-over-quarter and relatively flat over the prior year. The sequential increase reflects both better sales as we recover from lockdowns in South Africa and the continued strengthening of the rand versus the U.S. dollar. With respect to the sale of Ctrack South Africa, the transaction continues to progress according to schedule and will continue to anticipate closing this sale at the end of the quarter, subject to regulatory approval and other closing conditions. This will lead to approximately an additional $36 million to our cash balance based on the current exchange rate. Speaking of cash balance, cash at the end of Q1 was almost $60 million, including cash classified for held for sale, up almost $20 million from Q4 of 2020.
The increase in our cash balance reflects the net proceeds of $29.4 million from our ATM offering in January and solid cash collection offset by our need for higher levels of in-transit inventory as we transition from air to ocean shipments. We're taking these actions to better manage cost, as well as buying long lead time components to ensure we can meet customer delivery schedules going forward. From this point forward, I will focus on non-GAAP measures. A reconciliation from GAAP to non-GAAP is detailed in our earnings release and is found on our IR webpage. For IoT and mobile business, gross margin was 26.1%, up 50 basis points from the 25.6% in the prior quarter, and up approximately 560 basis points compared to Q1 of 2020.
Gross margin improved both sequentially and year-over-year, the result of a higher mix of 5G and Inseego Managed revenue and the decline of lower margin 4G sales from 2020 high, as well as solid execution throughout 2020 and 2021 year-to-date in improving supply chain efficiency. Going forward, we expect a higher mix of 5G and software revenue and new initiatives to improve operational efficiency will lead to better economies of scale, which translate into improved IoT and mobile gross margin steadily as the year progresses. Our enterprise SaaS solutions gross margin for Q1 was 63.8%, up 130 basis points from 62.5% in Q4, and down 20 basis points from prior year. Total company gross margin for Q1 was 35.7%, up 410 basis points from 31.6% in Q4, and up 420 basis points from the 31.5% in Q1 of 2020.
As discussed earlier, the increase is predominantly a result of better sales of higher margin 5G products and software uptake in our IoT and mobile business. Q1 OpEx was $26.7 million, down $5.6 million compared to $32.3 million in Q4. The decrease was primarily a result of the research and development spending related to our 5G product programs with the capitalization impact over the course of the software's useful life. We capitalize our external use software on a product-by-product basis per the accounting guidance. Therefore, the capitalization and amortization impact to our R&D will cause certain volatility in our quarter-over-quarter operating expenditures. In addition, our testing and certification was lower versus the prior quarter. Sales and marketing and general administrative charges remained relatively flat, with the delta being largely seasonal changes due to product launches and annual audit fees.
Our Q1 non-GAAP net loss was $7.7 million, or a - $0.08 per share, versus $6.9 million or a loss of $0.07 per share in the prior quarter, and a loss of $5.7 million or $0.06 a share last year. This result reflects our ongoing investment in 5G and SaaS product development and additional sales resources offset by stronger gross margins. Adjusted EBITDA for Q1 was a loss of $900,000 versus a positive $7 million in Q4, and a loss of $1.7 million last year. For additional details on non-GAAP and adjusted EBITDA results, please refer to the reconciliation tables in our press release. Finally, some thoughts on the rest of 2021.
As stated previously, the company continues to believe that the second half of this year will be better than the first half, driven by 5G sales growth from existing customers, new 5G carrier deployments primarily internationally, revenue growth from our entry into the enterprise market, and increased software revenue across our product line. We're bullish due to the many positives that have been articulated today. With the expected closing of the Ctrack South Africa sale at the end of the second quarter, our financials will more accurately reflect the 5G pure play, as mentioned by Dan. With that, let me turn it back to Dan for closing remarks.
Thanks, Bob. We're delighted to have you on the Inseego team. I want to close by expressing my sincere thanks to our dedicated employees who continue to do an amazing job in these challenging times. They are the driving force behind our numerous accomplishments, and I can't thank them enough. We've made significant investments over the past two years to create a best-in-class 5G and software solution portfolio and in sales and marketing resources to capture significant market opportunities. These investments have begun to be reflected in our results. The strength of our portfolio has helped us succeed in initial customer engagements across multiple regions in the developing fixed wireless access market with carriers and enterprises. We have excellent customer relationships and are seeing tremendous traction with our industry-leading 5G products and new software as a service solutions.
This gives us more confidence than ever in our ability to become a high-growth, high-margin, 5G and SaaS global solutions company generating strong free cash flow. With a strong second half, you can only imagine what 2022 will look like. Thanks again, everyone.
We will now begin the question and answer session. To ask a question, you may press star then one on your telephone keypad. If you're using a speakerphone, please pick up your hands up before pressing the key. To withdraw your question, please press star then two. At this time, we'll pause momentarily to assemble our roster. Our first question comes from John Marchetti with Stifel. Please go ahead.
Thanks very much. Dan, if I could, just a couple of quick questions on the overall business trends in the enterprise. You mentioned some of the initial sales that you saw here in Q1. How do we think about that as we start to move through the year, contributing to that second half strength? Obviously, big focus on 5G products, obviously, with mobile hotspots and things of that nature, but how do we think about the enterprise opportunity? Is that more a 2022 event, or do you think it's a real contributor to that second half growth outlook you just highlighted?
Yeah. Hi, John. Great question. Well, as you know, we just recently launched our enterprise 5G portfolio. It is gaining traction in the market. Terrific that T-Mobile for Business certified three of our products, indoor and outdoor fixed wireless products. We're starting to work with them on market opportunities and then broadly through our distribution channel that we described in North America via APAC. We see it beginning to contribute in the second half. It will be a ramp as usual. We have the portfolio, we have the software solutions to go with it, and the distribution in our target market. It's a ramp in the second half as we see it and certainly carry great momentum is what we're expecting to see going into 2022.
Dan, just as a follow-up to that, is there a better margin profile with those enterprise products relative to maybe the mobile hotspot products? Obviously the software piece is a very different margin profile, how do those solutions stack up, I guess, margin-wise, relative even to the 5G mobile hotspots?
Yeah. Well, as we all well know, the enterprise market in general has a different gross margin profile. There's the benefits of the distribution. I will say this, yes, it is higher than, if you will, the carrier gross margin profile. As far as this fixed wireless access products, I would expect somewhere in the mid-40s.
Then maybe just a last question from me, and I'll jump back in the queue. From a software perspective, obviously, you mentioned some of the carriers that are now offering alongside, but as you go to market in that enterprise market as well, is there a different attach rate there for software? Is it higher? Is it lower? Just curious how that stacks up relative to what you're seeing on maybe some of the mobile hotspot side as well. Thank you.
A great question in addition, John. Thank you for that. Well, we're seeing strong attach rates across the board. As you know and as we announced, T-Mobile has adopted our Inseego Managed solution as part of their initial 5G hotspot deployment. AT&T is now adopting Inseego Connect to offer to their enterprise customers. That's as part of the launch of the new 4G hotspot business with them. All of the conversations with enterprise, and all for the right reasons, but they want to look at how they can deploy, how you acquire, how you manage, and how you secure their enterprise. They don't have their own, so naturally it's a packaged solution.
We're also seeing an offering we call Inseego Select that is kind of, if you will, a bundled offer for select sales partners that would sell the complete package in a rental type of model, which will add to recurring revenue, good recovery, high gross margin. The answer is both. We're seeing strong interest and attach rates in both carrier and enterprise, John.
Thanks very much.
Thank you.
Our next question comes from Mike Walkley with Canaccord Genuity. Please go ahead.
Great. Thanks for taking my question. I guess first place to start is just good to learn that 4G levels are above pre-COVID areas, but just trying to get a cadence of with the work from home and school from anywhere type of surge in demand, how should we think about the cadence for that business and the overall maybe IoT and mobile solutions businesses? Is Q1 the trough, kind of a seasonally softer quarter and it builds throughout the year, or is there still maybe a pocket of 4G coming out in Q2 and then a stronger second half of the year?
Hey, Mike. Thanks very much. A great question. As we've said and mentioned on the earnings call previously, we are seeing our 4G demand levels for our newest generation hotspots selling at higher levels than pre-COVID. That is what we're seeing. We see no evidence of that trailing off. I will say this, the onset of COVID and the dynamic that played out towards the end of the first quarter drove 4G revenue, which was a combination of both some of our older legacy products that were coming near end of life, as well as our newer generation, our Cat 22, Cat 20 LTE products. The dynamic that played out from 2020 to this year is a number of those end-of-life older 4G products have just tailed off. They were sold out. They're no longer sold in the market.
They were naturally reaching their end of life, and in fact, an uptick in demand accelerated the end of life. That revenue is being substituted now by our newest generation 4G products, and that's what I referred to as the run rate we're seeing is higher than pre-COVID of those. Of course, now 5G is coming into the mix, software services is coming into the mix. Long story short, there's a substitution effect going on in our revenue composition. The good news is what's driving revenue now is our latest generation LTE, in terms of that ongoing work from home demand, and 5G and some of the newer products. We have fresher, newer revenue that's making up our Q1, and will make up the quarters going forward.
Great. Thank you. Just as we think about gross margin trends, maybe on a short- term, is there any component constraints that are tight in the inventory creating maybe some gross margin headwinds as you maybe expedite shipments or try to track down components? It sounds like over time with software and with the mix changing, you should see gross margins improving pretty steadily throughout the year.
Yeah. I've heard an expression called Chipageddon. I don't know if that one's caught on yet. No, again, great question, Mike, and thanks for the question. It's obviously topical. As we said, we're doing a good job, and we did get out in front with the semiconductor dynamic going on with our key partners. We did advance purchases to secure component supply, which is reflected in some of our use of cash. We see this prevailing, this condition prevailing, I think through the end of this year, likely into the early part of 2022. Now, there's a lot of the technology companies are standing up new foundries, billions going in, so there will be recovery in supply. So far, we've not had customer deliveries impacted. We've not seen price increases.
Having said that, if that does begin to occur, we will go back to our playbook last year, where based on the demand, we've passed on price increases, and we would fully expect to do that going forward. That's a conversation we have with our customers, but I think the macro conditions are well understood. We are going to keep our eye on the ball, working on the forecasting and pre-planning, spending a lot of time with our customers talking about future demand and with our key silicon suppliers, securing supply.
Great. Last question for me, and I'll pass the line. Just good to see Sunrise Switzerland as a new 5G customer. Just any commentary on a pipeline for adding new carrier customers for either fixed wireless or overall hotspots for 5G in 2021?
Well, yeah. In North America, I think we've talked about that. We're super excited about fixed wireless opportunities in North America, throughout U.S. and Canada. Great start having T-Mobile certify three of our fixed wireless products. It's fantastic. All the conversations we're having around the world involve both hotspot and fixed wireless. We're adding new carriers there. We're pursuing enterprise business. I would put it all in one category that we expect fixed wireless to start to take hold in the second half of this year in a big way. I think there's two elements going for it. One is the consumer, the home, broadband entertainment. We think the enterprise, with the number of use cases, will be an even bigger playbook for fixed wireless. We're spending a lot of effort on both enterprise and working with the carriers. Tons of RFPs, tons of conversations.
I think the markets are getting their bearings of how fixed wireless will play. Hotspots really started first, but now it's coming on strong. We see good momentum going forward in fixed wireless.
Great. That sounds encouraging. Thanks for taking my questions.
Thanks, Mike.
Our next question comes from Lance Vitanza with Cowen & Co. Please go ahead.
Thanks, guys, for taking the questions. I guess I have two. The first is, you've got the company on sound footing, but revenue came in a good bit softer than we were looking for. It sounds like, though, you were neither surprised nor disappointed with the revenue performance in the quarter. If that's correct, it just leads me to think that the problem is to a certain extent around messaging. Understanding you have a new seasoned CFO in place, will Inseego adopt financial guidance at any point over the year? If not today, perhaps in conjunction with 2Q earnings this summer?
Yeah. Well, hey, Lance. Thanks for the question. Well, as we were coming off, and we indicated, prior to this call that we were going to see a lower level of demand for our 4G. Couple of things, I mentioned that Q1 of last year and early into Q2 had a number of our older generation 4G USB prior generation hotspots that had come end of life. That's a year-over-year factor in comparison. In general then, we were now to our 5G products ramping up and our 4G LTE, the latest gen hotspot products ramping up. As I said earlier in one of the questions I responded to, there's a mix. A very different mix. We saw the first half of this year, generally a little lighter because of post-COVID. The good news is, though, the demand level of our LTE hotspot is higher than pre-COVID.
5G is now a layer on top. It's not a substitution effect. As that builds, as fixed wireless kicks in, as 5G Enterprise kicks in, software, we see it build throughout the year, and that's our comment of second half stronger than first half. On your question on guidance, we don't think it's prudent at this point in time. We did not provide guidance. There's a lot of dynamics going on in our business. All the things I just mentioned, which are nicely additive, as well as the Ctrack South Africa sale. We want to get that behind, then we'll revisit of how we can communicate to the markets. We just don't feel it is wise to provide guidance previously. We still think that we're not at the point that that's prudent, we'll determine when we feel comfortable in the future.
I think it's important to know that with all these new products, you need to reach a normalized run rate before you have your bearings on what the ongoing revenue will look like. A lot of factors behind not providing guidance. It's not that we're not interested in doing it or we're just somehow negative against it in general. It's just the dynamics going on in the business. It's just not prudent at this point.
Fair enough. Okay. The other question I had, and Bob, I think you had mentioned on your prepared remarks that the 5G sell-through in particular remains strong and that you expect, if I get it right, you expect orders to harmonize going forward. What I took from that is that the carriers were working off inventory in the quarter. Is that right? If that is the case, did you or could you say when you expect to see the benefit of the replenishment, so to speak? Is that a 2Q, or is it a second half event? Thanks.
Good question, and thanks. This kind of dovetails a bit to what Dan just said. We do see those trends continuing, and almost in perpetuity, and specifically, that's a Q2 trend, but we're also looking forward to building that momentum, and then that'll shape more color around forward look, and it will also shape maybe rethinking the terms of quantitative guidance. All of these trends are not an if, they're all a when. What we're trying to do is just gauge that level of momentum, that level of adoption, so we can move forward and articulate more strongly those details, if that's helpful to you.
Thanks. Yes, it is. Appreciate it.
Okay.
Yeah. Thanks. I guess I would add one other thing, by the way, that our largest 5G account now is T-Mobile. It has typically been for this company, Verizon. Verizon is going on strong. Demand level is good. It's not a cannibalization, by the way, of 5G to 4G. That's not what's occurring. It's additive. T-Mobile, thankfully, has jumped out in front as the largest 5G customer in Q1, and we expect to add more. I think the trend is up to the right. The timing, we need to work through that, and once we get there, we'll have our bearings and be able to come back with better information.
Okay. Thanks, guys.
Thanks, Lance.
Our next question comes from Michael Latimore with Northland Capital. Please go ahead.
Hi, this is Aditya on behalf of Mike Latimore. Could you tell me how much did international revenue contribute in terms of percentage?
Yeah. Hi. Good question. I guess just long story short, we don't break out the composition of revenue that way. We are growing our international business, as you know, through a number of the carrier win announcements. We talked about Western Europe, Japan, Australia, other places. International revenue is growing. It is still currently a relatively small percentage, and I think till such time that it reaches critical mass, we would then talk about absolute numbers. At this point in time, we're not breaking out international revenue as a percent of the business.
All right, fine. Any idea as to when you might actually expect the 5G sales to exceed the 4G sales?
I would expect to see that in the back half of this year. I think we had a question like this previously on a prior call. That was a comment I made then. Yeah. Same view, no change.
All right. Fine. Thank you.
Thanks very much.
Our next question comes from Scott Searles with ROTH Capital. Please go ahead.
Hey, good afternoon. Thanks for taking my questions. Dan, Bob, I hope you guys are doing well. I apologize, I got on the call a little bit late. I apologize if this is redundant, did you give any mix or breakdown between 4G and 5G? I just heard the prior comment now, T-Mobile is your largest 5G customer. Is T-Mobile your largest overall customer?
Hey, Scott. Great questions. Well, we did say on the call that 5G was 20% of total revenue. If you combine 5G and SaaS, that reached in the neighborhood of 44% of total revenue. That's just showing the differential in mix. T-Mobile isn't yet our largest customer. There's a large run rate of 4G LTE sales continuing at Verizon. It is, however, our largest 5G customer in terms of new products. That's kind of the landscape there.
Good. Maybe to follow up on the Verizon account, there were some issues with Franklin Wireless recall this quarter. I'm wondering if you've seen any pickup related to that. Do you get any of that opportunity, or is your product more high-end than them using, for example, a lower-end Orbic solution?
Great question. They really don't cross over because it fundamentally is exactly as you said, our product is a higher-end product geared for enterprise. Some of these other products you mentioned, Franklin, are so-called lower-end products, they really actually don't overlap in the target markets. I guess Franklin's working through these issues. There again, it's not really a market sector that pulls on our product. That's frankly a benefit, the way we like to see it.
Thank you. This concludes our question and answer session. I would like to turn the conference back over to Dan Mondor for any closing remarks.
Great, thanks. Well, great questions to end on. Thanks again, everyone, for joining us today and tuning in. We're off to a great start to what we certainly expect to be a fantastic year with our new revenue streams from 5G, fixed wireless, SaaS, and enterprise as the main events, and recurring revenue growth with strong margins. Thanks again, everyone. Take care, everyone.
The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
