How it happens:
If you are near the Canadian or Mexican border, you may receive the signal of a tower in a neighboring area. This is known as signal bouncing. This can also occur if you're on a regional rate plan and you get close to the coverage border.
Customers in the following areas could be charged roaming for domestic calls, data usage, or text messages:
- Near the Canadian border
- Near the Mexican border
- Near the Gulf of Mexico
- Near a coverage border for regional plans
Example: You are on a Pacific Northwest plan (Washington, Oregon, Idaho) and you receive a signal in Montana or California.
When signal bouncing occurs, calls appear to be placed in Canada, Mexico, the Gulf of Mexico or a neighboring state, and you are charged accordingly.

When you register on another country’s network, you should receive a free text message notifying you of the change, future courtesy messages, and self-help options.
Note: Laptop stick and netbook devices receive these text messages via the Connection Manager user interface.
How to prevent roaming charges:
Manually select T-Mobile’s network each time the handset is powered off and on.
- To follow the manual network selection process, use the steps outlined in the common procedures for your handset or data device.
- For data usage, turn off data roaming while you are close to the border.
