4S eSIM eSIM Data Plans for Iran

4S eSIM does not provide a truly unlimited data eSIM for Iran. All plans labeled “Unlimited – 1 days” through “Unlimited – 15 days” contain a fixed high‑speed data allowance (e.g., 3GB, 5GB, 10GB, 20GB, or 30GB) and after the cap is reached the speed throttles to 1000 kbps. Travelers who need a large amount of data without any speed reduction can choose from the fixed‑data plans, such as the 30 GB plan valid for 15, 30, or 90 days, or the 20 GB plan valid for 5 or 7 days. These high‑data fixed plans may offer a more cost‑effective solution for users who wish to avoid throttling or for those who are not extremely heavy data consumers.

4S eSIM does not offer any eSIM plans that include a local phone number or SMS capability for travelers going to Iran. The available plans are limited to data‑only options.

Travelers who need the ability to make voice calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but these services may be restricted or blocked in Iran. Users are advised to check the accessibility of their preferred apps before purchasing a plan.

4S eSIM lists 39 single‑country data plans for Iran, and no multi‑country options are currently available. The plans are split into daily data cap packages—seven variants that refresh the data allowance each day for the chosen validity period—and fixed data cap packages—thirty‑two options that provide a fixed amount of data for the entire validity duration. Across all offerings the price range extends from $7.39 for a 714 MB one‑day plan to $227.35 for a 30 GB 365‑day plan, while the data caps cover 714 MB to 30 GB in total.
