MeSIM does not provide a truly unlimited data eSIM for Yemen. The plans that carry “unlimited” in their name are global packages that give a fixed amount of high‑speed data each day—500 MB, 1 GB, or 2 GB—and after that limit the speed drops to 384 kbps. These packages are not unlimited for Yemen.
For travelers to Yemen, MeSIM offers fixed data plans such as 20 GB for 30 days, 10 GB for 30 days, and 5 GB for 30 days. These plans give a set amount of high‑speed data that must be used within the validity period and can be more cost‑effective for most users unless very heavy data consumption is expected.
