Data roaming

Important notice about domestic data use while off the T‑Mobile network

As of April 5, 2012 there is 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 once they reach 80% and 100% of their domestic data roaming allotment. If the domestic data roaming allotment is reached, then data service will be unavailable until the customer returns to a T‑Mobile coverage area, the next bill cycle begins, or the customer changes their full-speed data allotment (temporarily or permanently) to an option that includes more domestic data roaming. This does 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 www.T‑Mobile.com/Coverage.html. If you have a T‑Mobile ONE™ plan, or activated a simple Choice™ plan on or after November 15, 2015, your domestic data roaming allotment is 200MB. If you signed up for T‑Mobile before November 15, 2015 and don’t have a T‑Mobile ONE™ plan, the chart below outlines the domestic data roaming allotment associated with each full-speed data allotment option. To use this chart, review the left column to identify the megabytes (MB) or gigabytes (GB) included in your current data plan option, and then see the domestic data roaming allotment that applies on the right. If you don’t know what your full-speed allotment is for your data option, find out by reviewing your Plan page on my.T‑Mobile.com (check out the line that says “Data Service”), by reviewing the Available Service Section on page 1 of your bill (ex: Classic Simple 200MB Data Promo) or by dialing #WEB# send from your mobile phone.

If Your Current Full Speed Data Allotment is...                                Then Your Domestic Data Roaming Allotment is....

Off-network data use may occur even when you are within the T-Mobile coverage area. See your device’s user manual for directions on how to update device settings to avoid domestic roaming. Many user manuals are available online from T-Mobile Support.
