Card Centric Solutions’ SIM based Call Back application allows your subscribers to reduce their calls in international roaming by routing the calls through local telecom operators. This is done through the STK menu by activating callback feature to let your SIM Card detect when you are roaming and automatically asks you to dial your counterpart with call back option or not. Given that the Call Back option is selected, then call back occurs when the originator of a call is immediately called back in a second call as a response.
The call back system routes the calls through the networks in place, where the rates are much lower. This way your subscribers enjoy the lower international call bills and appreciate your service level which enhances their loyalty to your company and brand.
