MeSIM does not provide a truly unlimited data eSIM for Saudi Arabia. The plans that carry “unlimited” in their name give a fixed amount of high‑speed data—such as 500 MB/day, 1 GB/day, 2 GB/day, 3 GB/day or 5 GB/day—within a specified validity period (e.g., 3 days, 5 days, 7 days, up to 20 days). Once the allotted high‑speed data is used, the speed drops to 384 kbps, and the plan still expires after the set number of days.
Travelers who want more data than the “unlimited” bundle allows can choose from MeSIM’s fixed data plans, which include larger data allowances such as 50 GB for 3 days, 5 GB for 7 days, or 10 GB for 10 days. These fixed‑data plans can be more cost‑effective for heavy users and maintain higher speeds throughout the validity period.
