Looking at the capabilities of both carriers, we would expect MetroPCS to be above GoSmart on a depth chart, thanks to its higher pricing and larger number of customer options. A timeline reveals that T-Mobile first offered to purchase MetroPCS last October. Two months later, the nation's fourth largest carrier said it would start testing GoSmart in "select locations".
Juggling two major pre-paid operators while running a major post-paid operation is nothing new. Besides T-Mobile's work with MetroPCS and GoSmart, the nation's third largest carrier, Sprint, is busy with its fingers in the pre-paid pies of Boost Mobile and Virgin Mobile.
