said by Terabit:The problem with tmobile is that their plans are not competitive and their network is stuck on frequencies used by nobody but themselves. This enormous limitation has prevented a lot of people from switching.
TMobile's PAYG
$100 10¢/min 1 year
$50 13¢/min 90 days
$30 19¢/min 90 days
$10 33¢/min 90 days
WTF is that? What is "¢/min", minutes of what?
If you're talking about GSM Voice and Sprint-like slow data, then T-Mobile USA has the very same frequencies that AT&T and any other GSM provider in North America has; supported by all iPhones and nearly any GSM world phone. It's more difficult to find a phone that wouldn't support it, than the other way around.
Personally, I have their 5GB@4G plan for 30$/30days, with a Galaxy Nexus from Google for ~350$; getting great speeds and can't complain about coverage; price is as good as it gets in North America!
AT&T doesn't even come close as far as competitiveness goes! StraightTalk, maybe; but their ToS prohibits just about anything: »
[StraightTalk] T&C prohibit streaming, app shops [legal][TC].
