You can buy any of the following voice packages to enjoy as many on-net calls for as long as you wish, during the package validity.
All of the above packages are for on-net calls (form an Irancell line to another Irancell line), and off net calls (from an Irancell line to other lines) would be calculated considering pay as you go plan.
Please note that if you have an active voice package, the cost of calling Irancell customer support (700 and 09377000000) is not deducted from the voice package, but for prepaid SIM cards, it is deducted from the total balance, and for postpaid SIM cards, it is added to the bill.
