Comet SIM eSIM Data Plans for Mexico

Comet SIM does not provide an unlimited data eSIM for Mexico. The available plans for Mexico are fixed data bundles that must be used within a 30‑day validity window. Examples include the Mexico eSIM — 20GB / 30 days plan, which costs $48.90 USD, and the Mexico eSIM — 10GB / 30 days plan, which costs $28.90 USD. These fixed‑data options may be more cost‑effective for most travelers, unless an user is an extremely heavy data consumer who requires unlimited coverage.

Comet SIM does not provide a Mexico eSIM that includes a local phone number or SMS capability. The provider offers only data‑only plans for Mexico. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Mexico before purchasing.

Comet SIM offers five single‑country plans and five multi‑country plans for use in Mexico. The single‑country options provide a range of data caps from 1 GB to 20 GB, while the multi‑country plans cover a similar data range but allow roaming across multiple destinations. Prices for all plans fall between roughly $3.90 and $119.90 USD, with validity periods ranging from 7 to 30 days.
