Hey there magenta1428247 !
Sounds like you're planning a trip and the last thing we want you to be worried about is coverage. Fortunately, you can check our International Plans | Traveling Abroad without Roaming Fees | T-Mobile page and take peek at the coverage we have for Mexico and other countries. We have this tool available for folks so they can get an idea of the service they'll get before they get there. Have a nice trip!
