I need a code to register for MiSETAR. How do I get this code and how long is it valid?

Your code can be found at the bottom of the your monthly bill. You can also ask for it when visiting any SETAR Teleshop. Do not forget to take valid identification document with you.
Are you not the main user? Then make sure you have a letter of authorization from the main user and a copy of a valid identification document of the main user with you when visiting a SETAR Teleshop.
