I've had my OE for about a year now and it's worked fine up till about 2 weeks ago. My phone now will not send text messages or make phone calls while i'm connected to my home WiFi (which has excellent connection) and when i disable the WiFi and it turns into 3G it also wont send text messages or make calls and the 3G turns a greyish color. But it will send text and make calls elsewhere outside my home fine. I've factory rest my phone, taken out the battery switched airplane mode on and off and nothing seems to be helping anybody know how to fix the problem or what may be the problem? please if you do help me it would be appreciated so much!
