ETravelSim does not offer a truly unlimited data eSIM for Mexico. All plans that carry the word “Unlimited” give a daily high‑speed data allowance of 2 GB; after that daily quota is exceeded the speed drops to 2048 kbps. Travelers who need unrestricted high‑speed data can instead choose one of ETravelSim’s fixed‑data plans, such as the Mexico eSIM 50 GB – 30 days plan, which provides 50 GB of high‑speed data for 30 days, or the Mexico eSIM 20 GB – 30 days plan, which offers 20 GB for 30 days. For very heavy data users, a fixed plan may be more cost‑effective than the daily‑limited options.
