Best eSIM for Mexico (2026)

Nomad’s official Mexico page listed unlimited plans of $10 / 3 days, $17 / 5 days, $22 / 7 days, and $30 / 10 days. We did not find a 15- or 30-day unlimited Nomad Mexico price on the official page. Official fixed plans include 1 GB / 7 days at $5, 3 GB / 30 days at $7, 5 GB at $11, 10 GB at $15.50, and 20 GB at $27.50. Official networks are AT&T and Movistar. Official installation language: activate within 60 days of purchase or the plan starts automatically. That official window is shorter than Saily’s official 180-day window and matters if you are buying in November 2026 for a later spring-break 2027 trip. Official language also says coverage may not include overseas territories; contact Nomad support to confirm before purchasing. We did not find an official daily fair-use figure for Nomad’s unlimited Mexico plans.

Saily’s official Mexico FAQ listed plans from US$4.99 for 1 GB / 7 days to US$71.99 for unlimited / 30 days. The official page also lists 10 GB / 30 days at $23.99. Other mid-size fixed rows are not listed on the official page, so we don’t add those prices here. Official activation: 180 days, with an official example that a plan purchased today and left unused would activate automatically on May 10, 2027. Official hotspot language: “limitless mobile hotspot sharing.” Official language: Mexico is also part of a Latin America regional plan covering 12 destinations, including the USA — that regional plan is a different product. Networks were not named on the official page.

Airalo’s official Mexico page lists two products. The data-only unlimited ladder, on AT&T plus two unnamed networks, runs from $10.50 for 3 days to $62.00 for 30 days, including $23.50 for 7 days and $43.00 for 15 days. Airalo’s official fair-use policy for unlimited plans is 3 GB per 24 hours, then 1 Mbps. A separate official Movistar product includes data, minutes, and SMS — for example 10 GB + 100 mins + 100 SMS for 7 days at $23.50, or 50 GB + 500 mins + 500 SMS for 30 days at $54.00. Those are not the same plan as the unlimited data-only ladder. Official pages also showed Latin America, North America, and Global starting prices; those are different products.

Holafly’s official Mexico page listed unlimited-day prices of $11.50 / 3 days, $18.50 / 5, $24.50 / 7, $32.90 / 10, $44.90 / 15, and $66.50 / 30, on Movistar Mexico and Telcel. Official coverage language says the plan does not provide coverage on Holbox Island or Contoy Island, in Chiquilá or Ojo de Agua, or along certain sections of the road between Playa del Carmen and Mérida, and that coverage may be weaker or unavailable in rural areas, on islands, and along roads far from main populated areas. Official hotspot language is 1 GB of shareable data per day of the plan. Official FAQ: a possible operator fair-use slowdown, generally for no more than one day. Always On is 1 GB of backup data every 30 days in 150+ countries if you keep the eSIM installed. Official language says the digital eSIM is data-only and that a Mexico eSIM cannot be used in the United States; a North America eSIM is a different product.
