eSIMCard does not provide a truly unlimited high‑speed eSIM for Mexico. All plans that are titled “Unlimited” are actually fixed‑data plans that give a capped amount of data—typically 1 GB per day—and once the cap is reached the speed drops to the reduced rate listed in the plan details. Therefore these plans do not offer high‑speed data without limits.
Travelers who need more data can select one of eSIMCard’s fixed‑data plans, such as the 50 GB 30‑day plan for $131.61 or the 100 GB 180‑day plan for $185.68. These are just two examples of the broader selection of high‑data‑allowance options that are available for use in Mexico, and they can be more cost‑effective for heavy data users.
