Why T-Mobile 4G Data May Download Slow

T-Mobile Throttling Data While Roaming AT&T's Domestic Network

Beginning on April 5, 2012, there will be a limit on the amount of data that can be used while a T-Mobile customer's device is connected to another provider's network ("off-network" or "domestic roaming"). Customers that are domestically roaming will receive free text message usage alerts for data. If the roaming data limit is exceeded for a Rate Plan, then data service will be suspended from off-network roaming until the start of the next bill cycle, or a qualifying change is made to the Rate Plan. This will not impact (1) voice usage, and (2) data usage on the T-Mobile network.

To determine domestic roaming areas, see the T-Mobile data coverage map by visiting T-Mobile.com/Coverage. The domestic roaming data allowance for each Rate Plan is outlined in the chart below. To use this chart, review the Current Rate Plan Full Speed Data Allotment column to identify the megabytes (MB) or gigabytes (GB) included in your Rate Plan, and then see the domestic roaming data usage limit that applies on the right. The megabytes of gigabytes for a Rate Plan can often be found by reviewing the Available Service section on page 1 of the bill (ex: Classic Simple 200MB Data Promo) or by dialing #WEB# send from your mobile phone.
