Mexico eSIM on Telcel and AT&T

Each Mexico plan lists two Mexican networks, Telcel and AT&T, both with 5G, and the plans themselves allow 5G as well. In practice: 5G where either network offers it, 4G/LTE elsewhere. With two networks available, the phone can join whichever signal is stronger. To stay on one of them, turn off automatic network selection and choose it by hand.

AT&T in this list is AT&T's network in Mexico. The eSIM is a separate prepaid plan, paid from your SIMAREA balance, and it isn't tied to any AT&T account you have at home.

All Mexico plans send traffic out through Singapore, so sites see a Singapore IP address instead of a Mexican or US one. Navigation and messaging don't depend on it. A bank or streaming service that checks where you connect from may flag it.

Mexico plans come as fixed data packs or as a day pass, and none runs past 30 days.

• Data packs: a week with 100 MB, 500 MB or 1 GB; 15 days with 2 or 3 GB; a month (30 days) with 3, 5, 10, 20 or 50 GB.
• Day pass: a gigabyte at full speed every day. Past that allowance the connection drops to 512 Kbps, and full speed returns when the day resets. The number of days is yours to set at checkout.

A week in Cancún or Tulum

If hotel or rental Wi-Fi will carry most of your browsing and you want mobile data for maps, rides and messages, start with a small 7-day pack and add data when it runs low. Planning day trips to Chichén Itzá or the cenotes with photos to share on the way? A 1 GB pack, or a day pass, leaves more room.

Mexico City, Oaxaca and the road between

Moving between cities with navigation, translation and bookings open all day is what a day pass is for. A heavy afternoon can use up the allowance, and the slower speed still gets you to the next hotel.

A month of remote work

Working from a laptop over a hotspot, if your plan and phone allow it, uses far more data than sightseeing. The 20 GB and 50 GB packs for 30 days are the largest, and both can be extended on the same eSIM.

Set the eSIM up over Wi-Fi before you leave, whether you're flying into Mexico City or driving down from Texas. A Mexico plan's days begin at its first connection to Telcel or AT&T in Mexico, so the days before departure don't count. One plan works differently: the 100 MB pack for 7 days counts from installation, so add that one on the day you go.

When data or days run low, extend the plan you have instead of buying a new eSIM. Every Mexico plan on this page accepts a top-up, from the smallest 7-day pack to the day pass, and the new data lands on the same eSIM without a fresh QR code.

A Mexico plan only works in Mexico. If the trip also takes you into the US or Canada, every plan on the North America eSIM page covers all three countries. Before you switch, know what changes:

• The Mexican network. North America plans connect to Movistar in Mexico, on 4G, instead of Telcel and AT&T.
• Longer terms. They run up to 180 days, with 20 GB for 90 days and 50 GB for 180 days, where Mexico plans stop at 30 days.
• The IP address. Their traffic exits in Belgium, not Singapore.
• The same kind of day pass. The North America day pass also gives 1 GB a day and then slows to 512 Kbps, but across all three countries.

Spending most of the trip in Mexico and two days in the US? A Mexico plan plus a USA eSIM keeps you on Telcel and AT&T while you're in Mexico.

Heading south instead, note that no plan on the Latin America or Caribbean pages includes Mexico or Belize. The Latin America day pass and its 20-country plans do list Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama, so one of them can take over at the Guatemalan border. Guatemala and Belize each have their own plans. For a longer route, the Global 130 eSIM covers Mexico, on Telcel and Movistar, together with Guatemala, the US, and Canada.
