Missed Call Service

Missed Call Service ensures you never miss a call, even when you don’t have diversions set. Missed Call Service is the perfect solution for when you are out of coverage, have your mobile turned off or simply don't want to answer your phone!

How it Works?

Calls are directed to a short announcement letting your caller leave their number for you.

This service sends you a message with a summary of all the calls you have missed, once you come back into coverage, turn your phone on or have finished taking your call.

What it Costs?

It’s free. Your callers will be charged their normal call-to-mobile rates for the duration of the call when they interact with the instructions to leave their number.
