T-Mobile is horrendous outside of cities. If you drive to CO from TX you will not have any signal at all far more often than not.
I'm not claiming that tmobile has the best coverage, but what I will say is that acting like verizon and att are perfect on coverage is a fallacy. every carrier has bad areas. Plus, tmobile is building up its network in ways that it covers the most people all at once which is IN major cities first. Once tmobile does that it will build out.
It's hard for T-Mobile to compete with Verizon or ATT due to a lack of spectrum. THey simply can't compete and their coverage will always be more limited compared to the big two.
Except that tmobile is the fastest network according to OpenSignal, in a recent study. opps... The un-carrier movement won't be stopped. Source: http://opensignal.com/reports/2016/02/usa/state-of-the-mobile-network/?
Lol, OpenSignal is crowd sourced. Root Metrics which is a bit unreliable in itself is way more accurate than that. T-Mobile has great international coverage options, and good plans but to even pretend that T-Mobile is making a dent in Verizon or At&ts rural footprint is laughable. Even the "not now" network (Sprint) offers better coverage in some areas even if that's 1x coverage
T-mobile is serviceable and I have used them for about 12 years but man the coverage is spotty. I don't get reception in my house or at my work and they are on complete opposite sides of houston. At work it is about dial-up speed if I can get a signal.
