Now the 1 number is not able to make calls or send SMS. the number is able to go on the internet and recieve calls. I am also able to call voice mail and thier cutomer care. It is like thier is no airtime but I have loaded airtime and data. Vodacom have tried to reset sim service with No success and also No awnser why this is happening. I have tried it in numerous devices and the same problem presist. The Ref number given was 1- ********** 3333</p> <p> </p> <p>What am I to do</p>
