$40 4g LTE unlimited everything, metroPCS
That got my attention, so I checked their site. The only plan at that price I saw was:
$40.00 per month 4GLTE
Unlimited talk, text and data. First 250MB of data at blazing-fast 4GLTE speeds. Once reached, data speeds will be reduced for the rest of the plan billing cycle.
250MB is unlimited?
