I bought a f6 from metro pcs about 3 1/2 months ago had it on for one month and two months just wifi from my home to play games. I turn phone on about a week ago and my service was canceled so i had to make another account. When doing so i was given the option to keep my old number or get a new one. I got a new one. When done I rebooted my phone and first thing I checked was web and that worked. I go to make a call and get a " that service has been restricted please contact your service provider" so that's what i do. I ended up figuring why i was unable make calls my call barring for outgoing calls had been enabled but i never enabled it. So then i try every 4 digit code that myself, Metro, and Lg could think of the last 4 of both new and old numbers, 0000,5555,1234, and every pin i would normally use if i were to have set it. Both Metro and Lg can't help me. I can send phone to Lg but have to pay for shipping and if the phone isn't the issue then i waste time and money. I'm able to get calls and can make calls through Wi-Fi and it shows my number but if i disconnect from wifi call will drop. I'm hoping that someone might be able to help out.
