I have arrived in Tehran last night but I forgot to buy a sim card at the airport thus I need to know if it is possible to buy one from some stores or are there any specific trustworthy places where you could get one.
Just for one month.
There is nothing to be worried about. You can buy a SIM card in cities from Irancell or Hamrah-e-Aval central office. You just need to present a copy of your passport to activate the SIM card. You can also activate the internet package.
