Question:

How to use a new SIM card in Iran? Is it simply by buying the card and put it in our mobile phone, or should we register our mobile phone first so it will not get locked?

Answer:

There is no need to register your phone, but you need to register the pre-paid SIM card with a name and address, while there are registered SIM cards available too.
You can buy a prepaid SIM card of “Irancell” company which is available everywhere from the airport to the supermarkets at about 5 USD.
