I'm getting an "INVALID SIM" status on my status bar. I tries switching phone ON/OF but didnt work. My iOS is 6.1.4 but that though should not be reason for this invalid sim status.
Please help fix this problem

Q: INVALID SIM displayed on my status bar for my iPhone 5
The phone is probably carrier locked and you are using a SIM other than the carrier the phone is locked to.
