I have the LG Gossip, GW300FD, and where the name of the network should be, it says "Insert SIM and reboot." I've never seen this before, but I have seen the message "Inactive USIM" which is fixed easily by rebooting the device. I've tried rebooting it, taking out the SIM and repositioning it, but nothing works. It's been functioning fine for the past few weeks, except where "Fido" usually is it's said "Rogers", which happened after travelling to the States and coming back. This message came out of the blue, I didn't drop it or anything, and my network is completely disabled.

Help? ):
