What can be said about a merger between Sprint and T-Mobile?

It won’t happen, that’s what.


Let me dive into the heart of an announcement I’ve been mulling over for the past few days. Recently there has been small-talk in the wind about a potential merger between T-Mobile US and Sprint, whom are the fourth and third largest wireless carriers in the United States respectively. This announcement comes on the heels of an already-completed merger between MetroPCS and T-Mobile US which was finalized at the end of 2013. Both Sprint and T-Mobile US have expressed an interest in merging forces to take on ATT, who (despite direct marketing attacks against them from T-Mobile) still continues to show positive growth in last year’s 4th quarter earnings.

Although I can see the logic in another merger by T-Mobile US (especially a merger with a company larger than themselves) I don’t see the sense in choosing Sprint. Granted, T-Mobile US is aware that they have a lot of ground to cover in order to regain lost market share; prior to the merger with MetroPCS, poor management and advertising led to a sharp drop in new subscribers which ultimately forced the hand of T-Mobile US’s parent company, Deutsche Telekom, to either drastically re-invest in the American portion of their market or bail. Their ultimate decision was to go balls-to-the-wall and reinvest. Deutsche Telekom bought US prepaid carrier MetroPCS as their first move in a hard push to rebuilt their American market.

It seems the MetroPCS merger worked out well for T-Mobile US, so why don’t I see any sense in choosing Sprint as the next merger-buddy?  Although it isn’t common knowledge (or perhaps as common as it should be), Sprint and T-Mobile are currently operating on two completely different and incompatible wireless technologies.

Let me explain. There are three major technologies in wireless phones right now: GSM, CDMA, and LTE – the last of which you have probably heard of, if nothing else. What these acronyms stand for is essentially irrelevant; what is important to know is that each carrier uses either CDMA or GSM services as their backbone and then LTE service is applied on top of the backbone to provide next generation (or 4G) service.

For example, Verizon uses CDMA service as their backbone. CDMA provides Verizon customers with talk service, and 2G/3G data. From there, Verizon has applied LTE service on top of their CDMA service. When you’re in range of a Verizon tower that has had LTE service added to it – boom! You have 4G speeds.

It is important to note that carriers can only have one backbone. In other words (going back to our Verizon example) if Verizon uses CDMA as their backbone, their devices cannot detect or use GSM towers. This seems to be silly, but the two technologies are so completely different that there just isn’t enough room in phones to build in a radio for both services (Nerd moment: there are, of course, some exceptions to this rule and I'm sure one or two tech-savvy people will point that out to me. I'll squash that argument now by saying that if a carrier were to hypothetically use two backbones, it would need all of its phones to be dual-SIM and those phones would be financially unfeasible to market. Therefore, arguing that Sprint and T-Mobile could migrate over to a dual-SIM environment is not an option). There are a lot of reasons for this including the way in which the receivers are constructed and the frequency that each service uses in the air, but we won’t get into any of that here. After all, knowing why the two technologies aren't compatible isn’t necessary to understand why a Sprint and T-Mobile merger makes no sense.

Anyway, GSM and CDMA each have their own unique advantages. GSM uses SIM cards, meaning that you can easily carry your number from one phone to another and even from one carrier to another assuming that carrier uses GSM technology. CDMA, however, does not use SIM cards and therefore carrying your phone to another carrier is virtually impossible on a CDMA service. Additionally, GSM has greater 3G speeds and is the only of the two technologies that has the capability to talk on the phone and use data at the same time. CDMA, however, is cheaper to implement and can therefore cover a much broader area with much lower maintenance costs. This explains why Verizon has been able to advertise their reliability for so long – they simply have more towers because their towers are cheaper to mass produce – and why AT&T has been able to advertise the speed of their data network for so long.

(If you’re not a tech nerd who didn’t already know that, some lights should be going on in your head regarding all the confusing commercials you’ve seen about wireless service – but let’s get back to the point)

So, hang on a minute here – as far as “customer satisfaction” goes, GSM sounds like its superior. Even though CDMA is cheaper, shouldn’t every carrier be using GSM?

When CDMA was introduced it promised the ability to lock down a phone to a carrier – something Verizon really wanted to do. Why, you ask? The answer actually has to do with the way phones are sold in America. In the United States, carriers offer phones at low prices by locking you into a contract which brings down the price of the phone. We are the only country in the world that does that (and if you’re curious as to why, it can be found in my blog post here). Although this helps American customers to get very expensive devices at a low cost, it has proved to cause one major problem: if a subscriber cancels his service early, the carrier actually loses money on the deal. This happens because of the way contracts are structured and can be clarified by reading the blog post linked above. Although I could give you a clear explanation here, the reality is that I’ve rambled enough already. So, suffice it to say that subscriber cancellation in America = a loss of money, and losing money is bad.  

So what does this mean for us? Since every cancellation in America is a net loss, carriers want to give as few reasons as they can to subscribers that would be an incentive to cancel their service, and CDMA carriers use an inability to transfer your phone to another carrier as a cancellation deterrent. It sounds kind of underhanded, but it’s true.

Let me get to the point. There are two CDMA carriers in the United States: Verizon, and Sprint. Everyone else uses GSM (and prepaid carriers just mooch off of the towers that the big carriers put up, so they don't count). Everyone, including T-Mobile US, uses GSM. This means that Sprint and T-Mobile US would be merging two mutually exclusive networks and trying to somehow duct tape them together to make one network.

How would they do this? The only logical answer is to use the LTE service.

The only way to make a Sprint and T-Mobile US merger work would be to not merge their services, but instead share capital and patents to work towards a massive-scale LTE rollout.

Clarification: LTE, although currently being used as a service laid on top of either a CDMA or GSM backbone, can operate as a standalone backbone itself. LTE service has the ability to handle phone calls, data, and anything else a subscriber can throw at a mobile network. Therefore, Sprint and T-Mobile US would only have one reason to merge – to surpass Verizon’s coverage and then make a massive push to phase out their CDMA and GSM services altogether and migrate their network solely to LTE.

In the end, I just can’t see this happening. LTE rollouts are a massive undertaking. If they weren’t, we would have it everywhere by now. For Sprint and T-Mobile to try and make some kind of underdog push from behind and then magically become so efficient that they could beat Verizon to a full LTE conversion would be one heck of a feat – a feat that I just can’t see happening.

In my opinion, if either of them actually had the internal structure to take on Verizon’s rollout-pace they would have done it already.

So the verdict in all of this? Two wrongs won’t make a right. There is no way that a T-Mobile and Sprint merger would be financially or operationally feasible and to stand behind the notion that a push for a full LTE rollout would be a valid reason for a merger is not only lacking in common sense, but it’s something that the FCC will never buy. After all, the same argument was made just last year when AT&T tried to buy T-Mobile and the FCC didn’t buy that, even for two companies who would have to do far less work to successfully merge, as they already currently run on the same backbone.
The long and short is simple: let’s not get our hopes up. My prediction is that Sprint and T-Mobile US will see the FCC’s early skepticism and come to their senses, and that will be the end of that.
