TailSim does not provide a truly unlimited data eSIM for Mexico. The plans that carry “Unlimited” in their name give 1GB of high‑speed data per day and include a reduced speed after that daily limit is reached, so the data is still capped.
Travelers who need more data can choose TailSim’s fixed data plans, such as the 10GB, 20GB, or 50GB bundles that are valid for 30 days, or the 1GB/day plans that run for 3, 5, 7, 10, 15, 20, 25, or 30 days. These fixed plans offer a larger total data allowance and can be more cost‑effective for most users.
