That happened to me! I got a text from T-Mobile saying "Welcome to Mexico! Free international roaming is included in your T-Mobile plan. Enjoy your stay!". So I didn't have to pay anything, but it was kind of funny. But yeah, if you find out after, and do have to pay for roaming, that can be a less than ideal situation.Just make sure to turn off International Roaming on your phone if you decide to take TE around El Paso. Too many people get hit with roaming charges when their phones get locked to cell towers south of the border.
