T-Mobile just scored more airwaves, but is that even what their customers care about?

T-Mobile just picked up more low-band spectrum in its FCC-approved swap with Grain Management, and we asked readers if that closes the gaps in the carrier's service. Only about a quarter said yes. Most pointed to customer service and pricing instead, whether they carry a Galaxy S26 Ultra, an iPhone 17 Pro Max, or one of the best T-Mobile phones.

T-Mobile's spectrum grew, but readers had other things on their mind

T-Mobile's deal with Grain cleared FCC approval this month, and it runs almost backward from a typical upgrade story. T-Mobile hands over its idle 800 MHz licenses for Grain's 600 MHz holdings plus 2.9 billion dollars, and Grain has to hit three-year interim and eight-year final buildout deadlines so the spectrum doesn't sit unused.

We asked you, our readers, a simple question after covering the deal: are there still gaps in T-Mobile's service? Only 24.47% said it's good enough, and 35.37% wanted more spectrum. But the largest group, 40.15%, pointed at customer service and pricing instead, nothing to do with towers at all.

Why the numbers say more about habits than towers

This tracks with something we've heard before. T-Mobile customers weren't thrilled with the carrier's aggressive push into digital self-service either, so a coverage bump alone was never going to change how people feel about the brand.



Grain's side of the deal has drawn skepticism too. U.S. Senator Ted Cruz pushed the FCC over Grain's original ask for a 12-year buildout window, worried the spectrum would sit unused, and even with the shorter deadlines attached instead, customers won't feel any of this in their signal for a while yet.

Of course, if you're on AT&T or Verizon, this doesn't affect your bill or coverage, but we've heard the same pricing and service complaints about all three carriers, so switching alone won't address the problem.

What actually matters if you're a T-Mobile customer

If you're deciding whether to stick around, the spectrum deal alone probably shouldn't move you either way. It expands what the network can do down the road but does nothing for a slow hold time or a surprise line on your bill today.

For the 40.15% who flagged service and pricing, it's more useful to compare what T-Mobile actually charges and how its support holds up against Verizon and AT&T, rather than waiting on a rollout that's still years from finished.

My take on the mismatch

I get why T-Mobile leans on spectrum deals whenever it wants a win. Network numbers are easy to point to and hard to argue with.

But this poll is a clean reminder that coverage and customer experience are two different report cards, and only one seems to be improving. If T-Mobile wants that 40.15% to shrink, the fix isn't in an FCC filing, it's in how the company treats its paying customers.
