I had my ipad stolen while on holiday so reported it to 02 and ordered a new one which arrived the following day, then the same day my phone stopped working saying "sim not activated on network". I phoned 02 who sent a new sim for both my phone and the new ipad. The sim has not worked in the ipad since I received it 4 days ago despite repeated phone calls to 02. Everytime they remove the block it is automatically applied again. My phone sim card did work until today when I started receiving the sim not registered on network error. I've spent hours on the phone to 02 with no progress. I decided to check the IMEI number online which says that my phone has been blacklisted. Spoke to 02 again the first agent saying that the device was blacklisted because it was reported lost and the second saying that it wasn't blacklisted and saying I have to wait 3-5 days to hear back from the networking agent. Wish virgin and 02 had never merged have never had a issue with virgin.
