eSIMCard does not provide a truly unlimited high‑speed data eSIM for Iran. All of its “Unlimited” labeled plans actually cap usage at a set amount, such as 1 GB or 2 GB, and after that limit is reached the speed is throttled to 512 kbps or 2000 kbps. These plans are often titled “Unlimited For XDay” or “Unlimited Plus For XDay” but the data cap applies on a daily basis.
Consumers who require more data without speed reductions can choose from eSIMCard’s fixed‑data offerings. For instance, a 50 GB plan for 60 days and a 40 GB plan for 30 days give unthrottled high‑speed data. The provider also offers a 100 GB global plan valid for 180 days, which is unthrottled and covers Iran among many other countries. These fixed‑cap options may be more cost‑effective for travelers who need substantial data volume.
