The service allows subscribers of the UZTELECOM GSM network to stay in touch even with a negative balance. If the balance is negative, the subscriber makes a call to another subscriber of the mobile network. The callee receives a notification that the call has been sent. Example: subscriber A with a negative balance calls subscriber B, the call is redirected to the zero balance platform, the platform processes the call of subscriber A and sends a call notification to subscriber B, after which subscriber B sees the missed call from subscriber A on his phone.
Service cost: 50 sum.
When a subscriber selects a service on the IVR portal, a tariff of 50 sum will be applied from the balance of the mobile phone. They may not receive the ExtraCall service if subscriber B is roaming and outside the service area.
