No incoming calls when 3G network not available
Hi! I have a very weird problem! When using my iphone with 3g on i can receive calls normally . When i turn off 3g no incoming calls..
The problem is that in my country 3g network is not supported everywhere so when 3g not available i can not receive any calls.
This problem is not only on my iphone cause i have tried several iphones and same problem to all... This problem started on Os 3 and later... Anybody using Os till 2.2.1 is ok. Do you know a possible fix?
Sorry for my english
