I bought my iPhone 4 SIM free from an Apple store in the UK. It is not Jailbroken.


I am working out in Berlin for 3 months and am trying to get a german o2 SIM to work with the phone... apparently the SIM was activated when I bought it at the o2 store yesterday but when I put it in my iPhone it pops up with the "SIM failure" error and "Invalid SIM" on the top left corner of my iPhone.


o2 won't refund the SIM card and I am absolutely dependent on my iPhone working whilst I am out here in Germany.


I tried updating OS, syncing with itunes connected to wifi, hard-reset etc.. no joy.. it still works fine with my English SIM card so I don't understand what the problem is..


Please help!

iPhone 4, iOS 6.1
