I'm having this problem since Tuesday this week. I can send sms out from my phone, but I'm only receiving sms from MTN numbers. All Vodacom & CellC sms don't come thru. I tested from somebody else on CellC and also didn’t receive the sms. I checked the message center number and nothing has changed. I also phoned the call center and they gave me a code to unbar the phone. I tried it, but still didn’t work. Called them back and my query was escalated to a senior tech. Now I’m waiting for them to get back to me. Does anybody have the same problem?
