I received one yesterday. Worked for about 6 hours and then gave the 'No service' message. Tried everything - rebooted, switched off 3G etc

Looks like none of these work. From what I read, itll work until you need to change cellular towers and then the sim unlock will respond phone with the demo IMEI which makes the official sim lose contact with the base station. Only solution is to remove and put it in a working phone to get the correct basestation code

Ive been hearing that Universal SIM might work and indeed, it has a programmer, but there simply is no way to identify which IMEI request is the iPhone's and which is the base stations. Probably best not to waste more money on these
