Near-border roaming details
If you're near the Canadian or Mexican border, you may receive the signal of a tower in a neighboring area outside the U.S. 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. 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.
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're on a Pacific Northwest plan (Washington, Oregon, Idaho) and you receive a signal in Montana or California.
For more information, please read about our Domestic data roaming policy.
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.
Preventing near-border roaming charges
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 specific device.
- For data usage, turn off data roaming while you are close to the border.
If you believe signal bouncing occurred on your bill, please contact T-Mobile Customer Service so we can look into it.
