nextSIM eSIM Data Plans for Iran

No, nextSIM does not provide a truly unlimited high‑speed data eSIM for Iran. All plans that carry an “Unlimited” name in their title have a fixed high‑speed data allowance of either 1 GB or 2 GB for the specified validity period; after that limit is reached the speed drops to a reduced rate of 512 kbps or 2000 kbps.

For travelers who need larger amounts of data, nextSIM offers fixed‑data options such as the 10 GB 30 days Premium plan, the 20 GB 30 days Premium plan, or the 30 GB 30 days Premium plan, providing ample high‑speed data at a lower, more predictable cost compared to the high‑price “Unlimited” alternatives. These examples illustrate the available choices, but the full catalog contains additional high‑data plans.

nextSIM does not offer any eSIM plans that provide a phone number or SMS capability for travelers going to Iran. The available plans from this provider are strictly data‑only.

Travelers can still stay connected to the internet and use messaging or voice applications such as WhatsApp, Telegram, or iMessage over the data connection. These apps rely on data rather than a subscription to a traditional phone line, allowing calls and messaging without a local phone number or SMS service.

nextSIM lists 12 single‑country data packages that cover Iran, and 22 multi‑country packages that include Iran in their network. The available offers range from around $9.45 up to $1, 300, with data caps spanning from 1 GB to 50 GB. Choices include both fixed data–cap plans and daily data‑cap plans, allowing users to select either a one‑time data allotment or a consistent daily allowance.
