T-Mobile-Sprint merger: How to decide if you should switch
With the T-Mobile-Sprint deal nearing approval, the combined company will be more than an alternate choice when shopping for a US wireless carrier.

And another one's gone. With the Justice Department signing off on T-Mobile's $26.5 billion acquisition of Sprint in July, and with the Federal Communications Commission set to vote on the merger soon, the number of nationwide wireless mobile carriers will drop to three, for the moment.
With the merger moving ahead, you might wonder if now is the time to switch to T-Mobile. Joined together, the newly formed company has the potential to be much more than Sprint and the scrappy underdog T-Mobile were before. In both network coverage and subscriber numbers, it could become a significant rival of
The merged mobile carrier -- which will use the
name -- will have a combined 135.8 million subscribers, not far behind No. 1 Verizon's 158 million and No. 2 AT&T's 155.7 million. Perhaps most important for those 135.8 million customers, the combined carrier with its broader coverage will have a running start at building out perhaps the first usable
network that spans the country.
If you are considering making the jump, here's what to consider.
What will the combined wireless coverage be like?
For 4G coverage, Verizon and T-Mobile are neck and neck at 94 percent coverage of the country, according to OpenSignal, a mobile analytics company. AT&T is next at 89 percent, with
hitting 88 percent.
5G is a more interesting story. The major US carriers provide 5G coverage over a range of spectrum bands, and each carrier's mix of bands determines their coverage. At one end is "sub-6," which is extremely efficient and reliable at providing connections over long distances, indoors and out. On the other end, is millimeter wave, or "mmWave," which offers higher capacity, but over much, much shorter distances. And mmWave reception is fussier indoors, with seemingly everything -- walls, glass, hands -- capable of blocking the signal.
T-Mobile is strong on both the long-distance sub-6 side and the short-distance mmWave side. Sprint's strength lies in the midrange spectrum between the two extremes. So T-Mobile's and Sprint's combined spectrum should deliver broad, fast and reliable 5G coverage, especially in rural regions, which have lagged behind cities in access to fast connectivity.
As part of the deal, T-Mobile has agreed to aggressively roll out 5G to 97 percent of the US population in three years. And in six years, that number goes 99 percent. In rural areas, T-Mobile will have 5G coverage for 85 percent of the population in three years, and then 90 percent in six years. And T-Mobile also agreed to provide mobile broadband service in rural areas as part of the deal.

Where are the major carriers now with the 5G rollout?
Right now, Sprint has turned on its 5G networks in 9 metropolitan areas. T-Mobile has 5G networks in six cities. For comparison, AT&T has 5G up in 21 cities across 12 states -- from California to North Carolina -- but instead of citywide coverage, its initial rollout is via 5G hotspots that create wireless networking pockets. Verizon is live with 5G in 10 cities.

What about the lawsuit to block the merger?
A lawsuit brought by 15 states and the District of Columbia looks to halt the T-Mobile/Sprint merger. The suit filled in June by state and district attorneys general argues that the merger would "harm mobile subscribers nationwide by reducing access to affordable, reliable wireless service, hitting lower-income and minority communities particularly hard."
The suit has the potential to delay or halt the merger -- depending on the outcome -- and it is worth monitoring the lawsuit's progress before committing to the new mobile carrier.
What about Dish and a new fourth nationwide wireless carrier?
As part of the approval process, T-Mobile said it will sell some of Sprint's assets to the Dish satellite TV company, creating a new fourth nationwide carrier. Dish will get spectrum, Sprint's Boost and
businesses -- and prepaid customers -- and access to T-Mobile's wireless network for several years to help kickstart its own wireless service.
If it doesn't already, I'd be shocked if T-Mobile doesn't soon have a handful of switchover deals to tempt you to sign up.
Should you switch now?
With the merger, T-Mobile promises a network that'll provide nationwide service at predictable price: As part of the deal, T-Mobile has agreed to hold its prices steady for three years. With its broad coverage, promise of keeping prices steady and strength in 5G, the new T-Mobile is shouldering its way up. But the merger is not final and still needs to clear the states' lawsuit that looks to block the merge. If you are considering a move to the new T-Mobile, it's better to wait, keeping one eye on deals and incentives and another on the states' suit to see what happens before you switch.
