eSIMatrix does not provide any unlimited data eSIM for Mexico. All plans listed in the catalog are fixed‑data plans, each offering 20GB of high‑speed internet for a set period. For example, the Mexico 20 GB – 30 days plan is priced at $50.50 USD, and the South America 20 GB – 30 days plan, which includes coverage in Mexico and 16 additional countries, costs $85.50 USD. Choosing a fixed data plan can be more cost‑effective unless you anticipate using very large amounts of data, in which case an unlimited plan would be preferable.
