Missed call Alert (MCA) service, subscribers will not worry about missing an important call while their mobile is switched off. The missed call notification service detects when the subscriber is not able to receive calls, and logs the calling party’s number and the time of call for every call attempt made to the unreachable subscriber. MCA eliminates missed call uncertainties and frustration as your subscribers have increased control about who tried to call them when they were unavailable. It removes missed call handicaps and allows subscribers to gain an upper hand. This maximizes call connections and increase Average Revenue per User (ARPU).
