Randomly my phone will just lose service and say that my sim is not allowed. I just restart it and it works but its annoying. Anyone know anything about this?

They did for me for that same exact reason! No charge, if you call, they charge to ship it $10. I've had the problem once since then. Its been 2 months! Good luck!

My old phone used to do this... I thought it was because my sim card was pretty old and worn out. It turned out that the "contacts" that the sim touches were dirty and worn out and so wouldn't maintain proper contact.
Maybe see if that could be the problem. Or ask for a newer sim card.
