T-Mobile USA Review
I purchased a T-Mobile Samsung Galaxy SIII in July of this year. Whenever I leave their very limited 4G coverage area, the phone does not reliably communicate. It is unable to drop back to GSM or Edge. T-Mobile’s coverage is the WORST of any of the major carriers and this makes it all the much worse. Do not fall for their latest unlimited usage plan. It is only useful if you sit in one place with good 4G coverage.
