I have this I317m locked to bell. I am trying to use it on virgin mobile canada. From what I've read, I shouldn't have to unlock it to use it on virgin. Anyway, when I insert my virgin sim card, sometimes it'll say unregistered sim and other times it'll just tell me emergency call only. When I look under status, it knows my phone number and it knows that there is a sim card inserted, but it won't let me connect to anything. It's completely stock and on 4.4.2. It never asks to enter an unlock code when booted up and no combination of any symbols and numbers that I have found on the web results in anything happening through the dialer. I have an unlock code for it and I cannot input it anywhere. I am starting to think that I have a hardware issue of some kind and hope that it can be confirmed with help from you guys. Any advice would be greatly appreciated.
