Call a Friend

With the “Call a Friend” service you can keep in touch regardless of his account balance as the service allows you to make calls at the expense of the recipient.
 
To do this, while making calls, subscribers simply need to dial 999 before the phone number. The recipient will be notified that in case of accepting the call, its cost will be charged from his account and can decide whether to answer or not. In case of answering, the cost of the call is charged according to recipient’s current tariff plan.

Subscribers, at their discretion, can block or allow calls at their expense. For instance, if you don’t want to get such calls at all, you can block the service for everyone calling you. If you wish to block such calls only for certain phone numbers, you can add them to the “Blacklist”. In case you have already blocked the service for everyone, you can make exception for certain subscribers by adding their numbers to the “Whitelist”. And finally, the numbers of subscribers, whose calls you will always answer, can be added to the list of “Favorite Numbers”. Calls from these numbers will be connected automatically and you will not have to choose whether to answer or not every time.
 
You can set your preferences on receiving calls via the “Call a Friend” service by dialing corresponding requests, or through the “Internet Assistant” portal.
