Fix 3: Remove and Re-insert the SIM Card
Your phone can throw errors such as No SIM Card Detected, mainly when the SIM card is not properly placed in the SIM tray. For such a case, you must check whether the SIM card is correctly placed on the SIM tray on your device. Simply remove the SIM card tray from the left side and check if your card is properly placed.

Alternatively, you must also check for physical damage on your SIM card. Most of the time, the device will not detect the card due to damaged SIM cards.
