Complaint / review text:
I changed to T-Mobile a few months ago for the much better price on the Simple Choice Plan, as compared to other providers. However, shocked to find out now while traveling within the US, that data coverage is cut off by T-Mobile when you use only 50 MgB of data through their "service partners" on T-Mobile's map of T-Mobile coverage. They consider this "domestic roaming" and demand $40 additional to get only another 150 MgB of data. Nowhere in the Simple Choice Plan "Plan Details" does it state anything about a data limit on domestic roaming, or that T-Mobile demands an additional $40 for 150 MgB of data.
What the website Plan Details instead states is that the plan provides "unlimited talk, text and data while on our network with no overages. Ever." It goes on to point out that there is "unlimited international data and text while roaming in 120 countries". The only way to find out that T-Mobile cuts off your data at 50 MgB while "domestic roaming" is when they cut off your data and send you a text informing you that you're over the limit. Then when you call, they ask for $40 for another 150 MgB. Ridiculous, and bordering on fraud and false advertising, at best. Be aware of this hidden charge if you're considering T-Mobile, if you travel at all within the U.S.
