Most major US carriers typically include Mexico in their international coverage. Sometimes even at no extra cost.

If you’re traveling to Mexico with service from a foreign provider, be sure to review the 5G roaming agreements they have with local networks.

Prepaid Mexican SIM card: Purchase prepaid SIM cards online before your trip. Find the provider you’d like to work with and make your purchase online. They’ll send you a physical SIM card to insert and activate upon arrival in Mexico. Be sure to plan ahead and check delivery time and fees.
eSIM card: An eSIM connects you to local networks in Mexico and 24/7 customer service worldwide. With a quick scan of a QR code, you can set it up before you touch down. For affordable rates, convenient installation, and a reliable route for staying connected, try one of these eSIMs for Mexico.
Local SIM cards: You can purchase a SIM card in Mexico when you land with a local provider. In this case, you’ll go to a physical store, ensure that your phone’s compatible, and start working with the carrier based on local rates and contract availabilities.
