"Check APC" service
The "Check APC" service allows a subscriber to check APC (advanced payment card) before its activation.
The service is available to subscribers with individual pre-paid tariff plans.
In order to check a card you have to dial:
*55#serial number (12digits)#call-button
or send an SMS with a serial number to the number 55.
Note:
If you receive an answer that this card cannot be activated you’d better refrain from buying this card and call *500 to solve the problem.
It is necessary to check a card at a point of sale, not to scratch off a protective layer of a pin-code and not to damage the card’s cover.
