Why Is My Phone Saying There Is No Sim Card. Above all power off your cell phone. Power off your device and remove the SIM card from your Android device.
In case theres a problem with the SIM card itself its also not a bad idea to replace it. One way to test this is by inserting a SIM card from another cell phone that you know works fine. There is a chance that dust built up on your phone and it is creating a problem where the SIM comes in contact with your devices internal circuit.
Try using another SIM card.
I have removed the sim card while the phone is off and replaced after 10 minutes. This issue consistently happens. Once your phone is off press and hold the sleepwake button to turn it back on. Whatever the reason a solution needs to be found quickly when your phone says.
