I recently purchased a 2 degrees pre-pay sim for use in my son's iphone 3GS- for the 1st couple of weeks, all was good, but suddenly the phone says 'no service' and it does not receive any signal at all!
I have put the sim in an old blackberry and the sim works in that, but does not work in the iphone....
Similarly, I have put a Vodafone SIM into the Iphone 3GS, and that works fine in that as well, so the handset and the sim card seem to appear to fully work when swapped around......does anyone have any ideas as to why the Iphone 3GS does not work with the 2 degrees sim?
