Help me understand

ATT is trying to buy T-Mobile because, they say, T-Mobile has this delicious range of frequencies across the US that would enable ATT to end their bandwidth crunch. ATT does not actually promise that they will stop capping data plans if they get to eat T-Mobile.

Clearly, ATT has too many customers and too few resources to supply them. Quality must be going down.

Similarly, T-Mobile must have a lack of customer compared to their resources. So T-Mobile should be growing very quickly, attracting customers from other carriers with T's superior quality (and they can afford to lower prices, too, to attract even more).

The data, though, says (PC Magazine) that ATT is slightly more reliable than T-Mobile, and T-Mobile is slightly faster. And T-Mobile lost 50,000 subscribers overall, and ATT gained 2 million.

Does not compute.
