iRoamly does not provide an unlimited data eSIM plan for Iran. All of its listed plans for the country give a fixed allowance of 2GB per day, with validity periods ranging from 1 day to 10 days. The plans are sold at a set price for each validity window and include tethering and a reduced speed of 384kbps after the high‑speed data is used.
If a traveler needs more data, iRoamly offers fixed data plans with larger daily allowances. For example, a 2GB per day plan is available for 1 day, 3 days, 5 days, 7 days, or 10 days. Choosing a fixed data plan can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from an unlimited plan.
