So this weekend I found an old Ericsson T20 in my drawer and just for kicks I decided to try out the thing and after putting in my Telkom Mobile SIM the stupid thing wouldnt get a signal and I tried again with an MTN sim card and still No network so I just decided maybe the new sim cards are incompatible with old phones and put the phone back in the drawer. When I put the sim back in my iphone it wouldnt pick up network and that was the same with the MTN...no Network after being put in the T20. I just concluded my SIM cards were ruined and following day I went to the Telkom shop to do the sim swap and after telling the gentleman my story that I cant get signal he asked for my number, confirmed my name with the information he got from him PC and gave me the new Sim. What worries me is the old dude did not even even ask for an ID. Nor did he even check my story that the sim card was not working. In other words, someone who knows my name and fullname could have just walked into the shop and did a sim swap on my SIM card.
