  1. Hey do you know that MTN automatically set your phone to divert to voicemail? You cannot change this manually from your handset, so it means you have to phone them to cancel it before you go overseas! Grrr… None of the codes you’ve given above will work because of this!

    • I know that they set the divert to voicemail by default, but I’m pretty sure that the codes will work because I used them before travelling myself. Will double check though!
