MeSIM does not provide a truly unlimited data eSIM for the United Arab Emirates. All of its UAE‑based plans list a fixed high‑speed data allowance measured in a daily amount such as 500 MB/day, 1 GB/day, 2 GB/day, or 3 GB/day. After the daily high‑speed allowance is used, the data speed is reduced to a throttled rate (for example 384 kbps or 128 kbps) and the plan remains active until the validity period expires.
Travelers who need more data can choose a plan with a larger daily allowance. For instance, the UAE 5‑day unlimited eSIM allows 3 GB/day of high‑speed data, and the Saudi Arabia & UAE 90‑day unlimited eSIM offers 10 GB/day of high‑speed data. These fixed data plans are generally more cost‑effective than attempting to rely on a perceived unlimited plan, especially for moderate to heavy data usage.
