MCI, Irancell and Rightel cover cities and main highways on 4G; Lut Desert crossings, Alborz remote valleys and Caspian forest backroads can fade. Tehran metro has limited underground data. Check the network list above for Iran before you fly; it shows what is available right now, including options such as MCI.
There is no complicated Iran-only product to learn. NXTL is one global eSIM: the same profile you might use elsewhere works here on MCI when listed. Land, turn data on, and go — rates for Iran are shown live on this page because they can change.
Tourist SIMs are sold at Imam Khomeini airport with passport registration; activation includes a local number and data bundle. International cards do not roam into Iran, so a local or travel eSIM plan is required. That still makes sense if you will live in Tehran for months and need local calls. For a holiday or short work trip, most people only need data — and NXTL gives you that without the desk stop: install at home, keep your usual number for calls and bank texts, pay only for the gigabytes you use.
If Iran is one stop on a longer route, NXTL is built for that. Use data around Tehran and Isfahan, then keep the same balance wherever NXTL has coverage next. You are not locked into a single-country tourist pack.
Many global apps are restricted, so connectivity planning includes which messaging tools work before you leave the airport Wi-Fi. NXTL is built for that kind of Iran trip: data when you need it, without buying a new pack for every change of plan.
