TailSim eSIM Data Plans for Mexico

TailSim does not provide a truly unlimited data eSIM plan for Mexico. The plans that include “Unlimited” in their name actually give 1GB of high‑speed data per day; after that amount is used the speed is reduced to 512 kbps. For travelers who need more data without the daily limit, TailSim offers fixed‑data plans such as 20 GB, 10 GB, or 5 GB available for 30 days, which can be more cost‑effective unless extremely heavy data consumption is expected.

TailSim does not currently offer any eSIM plans for Mexico that include a phone number with outbound or inbound voice calling or SMS capabilities. Only data‑only eSIMs are available. Travelers who need to keep in touch while in Mexico can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these services, so it is advisable to confirm that the apps you rely on are accessible in Mexico before purchasing a plan.

TailSim offers 13 single‑country data plans and 13 multi‑country data plans for travelers in Mexico. The plans range from $3.99 to $86.99 and provide between 1 GB and 20 GB of data, with validity periods of 3 to 30 days. Some plans are structured as daily data‑cap options, where the data allowance resets each day, while other plans are fixed data‑cap, offering a total data amount for the entire validity period. Overall, TailSim provides 16 daily data‑cap plans and 10 fixed data‑cap plans across its catalogue.
