OK I have a problem and I'm going out of my mind, kinda.
When I got my S3 (Vodacom branded) I had to get a new MTN microsim as the microsim I had in my iPhone4 was too old.
Did a sim swop and all was well for a day or so. Up until my phone was completely blocked. No calls, no sms, no data. Phoned help centre and they gave me some magic code to get it all working again.
Now the phone is functioning, but most of my calls goes straight to voicemail, even though I have 100% signal. Sometimes the call just doesn't go through, sometimes it says the number is incorrect and once I was connected to a random person.
I've tried pretty much everything, entered a bunch of more miracle codes, to no avail. I've now cancelled all forwarding to voicemail and waiting to see how it goes.
My gut tells me there's something wrong with the new sim card.
or
The MTN sim in the Vodacom branded phone is not feeling at home.
Pleeeease someone have some advice on this??
