I have been having problems receiving phone calls from certain contacts - where it won’t ring on my end and just send the person straight to my voicemail without ringing. I’ve check all possible settings on my phone and am now led to believe it might be an issue with my sim card.
I am a prepaid customer and already have an account. I’ve gone and bought a new prepaid sim. Before I do the steps to change my sim card, do I have to do any sort of activation of the new sim or can I just pop the number in the change box and follow the steps from there?
