A video made by the nation's fourth largest carrier explains how T-Mobile has increased its spectrum, expanded radio capacity and added more connections to the internet all in an effort to make its network more reliable. It all sounds good as far as T-Mobile customers are concerned. Of course, if the AT&T deal to purchase T-Mobile closes, the latter will eventually benefit from AT&T's LTE network. But right now, T-Mobile 4G users have to be happy with how the carrier is spending money on its network.
