The “Fast” service allows subscribers of postpaid tariff plans to initiate switching to another postpaid tariff plan via USSD command or “My Viva” mobile application without the need to visit a service center.
To use this opportunity, one simply needs to apply for the switch of the tariff plan, by dialing *198# from the mobile phone and, entering the USSD menu, and choose the corresponding option.
You can also initiate the switch directly by sending the command of the preferable option, as shown in the table below:
