Hey I really need some help, I only get service when my iphone 5 captures a 3G network. If it doesn't, it gives me "no service", meaning that EDGE doesn't work. If I disable the 3G in settings, I will never get a service, it will always show "no service". Even if I turn off the cellular data, I wouldn't get service unless I'm in a 3G area. EDGE doesn't seem to exist on my iphone 5. I tried all the restore/reset options possible, it didn't work. The issue is from the phone, not the SIM card. I tried my SIM on another iphone, it works perfectly. I tried other SIMs on my iphone, and still no EDGE. Does anyone else have this problem? Can someone help me? It drives me crazy because I live in an area where I don't get a lot of 3G network, therefore I often have "no service".
