Saily does not offer a true unlimited data eSIM plan for Mexico. All of its Mexico‑specific options are labeled with “UNLIMITED” in the name but are limited to 3GB per day; after the daily allowance is used, the speed may be reduced, although the exact throttled rate is not specified. Global plans are capped at 30GB for 30 days with a reduced speed of 1024kbps once the limit is reached.
Travelers who need more data for their stay can choose a fixed‑amount plan instead. For example, a 20GB plan for 30 days is available for around $45.99 USD, and a 10GB plan for 30 days costs about $24.99 USD. These fixed data plans give a clear allowance and often prove more cost‑effective unless one is an extremely heavy data user.
