iPhone 3GS ends all calls
Hello I have an iPhone 3GS locked to EE in the uk.
When I put in an Orange SIM card which I have been told works on EE network.
The iPhone does not make any calls instead just ends the calls.
When I call the number from my home phone it says this number does not work
If I put the sim into Another phone everything works.
Also I can get a good signal and my iPhone locates other networks.
Thanks!
I can browse the web on 3G also the iPhone won't send or receive messages.
iPhone 3GS, iOS 6.1.6
