MeSIM does not provide a true unlimited data eSIM for Global (World). All of its Global plans list a daily high‑speed data allowance, ranging from 500 MB/day up to 2 GB/day, and once that daily limit is reached the speed is reduced (to 128 kbps or 384 kbps depending on the plan).
If a traveler needs a large amount of data without a hard limit, the available fixed data plans can be a cost‑effective option. For example, a 3‑day plan with 2 GB/day is available for $35.49 USD, and a 5‑day plan with 2 GB/day costs $61.99 USD. These fixed plans give a predictable amount of high‑speed data for the specified validity period.
