eSIMCard does not provide a true unlimited high‑speed data eSIM for Iran.
The plans that carry the word “Unlimited” in their names give a capped amount of data per day—1 GB per day (with a reduced speed of 512 kbps after the limit) or 2 GB per day (with a reduced speed of 2000 kbps). As soon as the daily quota is reached, the speed is throttled, so the data is not unlimited.
Instead, eSIMCard offers fixed‑data plans that give full‑speed data for the entire validity period. Examples include 50 GB for 60 days, 40 GB for 30 days, and 30 GB for 30 days. These plans are only a sample of the options available and may be more cost‑effective for travelers who need steady, high‑speed connectivity while in Iran.
