Hi, when a phone displays an insert sim message, it means that either the Sim card or the Sim tray where the sim card is inserted in the phone.
First, You can use the sim card on another phone to be sure that the sim card is still working properly. If the sim works with another phone, that means the sim tray where the sim card is being insert into the phone is bad and will need to be replaced.
Hi, when a phone says insert Sim,is either the Sim card or the Sim seater that allows the Sim to work is bad.
First try the Sim card on another phone and see if it will display insert Sim again.If it display that means the Sim card is damaged. But if no display,that means the Sim tray of your phone is damaged and will need to be replaced.
If the display says "Insert SIM," it means that the phone has no
contact with your subscription card (SIM card) that is inserted in the
phone. We recommend that you remove the battery and the SIM card, and
clean the connectors on the SIM card and the phone with a soft brush,
cloth or Q-tip moistened with any type of unflavored colorless alcohol.
At the same time, check that the card is not damaged or worn in
any way, in that case, the connector may not align with the connector
in the phone. Please contact your operator / carrier for a new SIM
card.
"Insert SIM" message is normally displayed on phones when a SIM card is not inserted on power-on or it does not detect the SIM card inserted.
Likely Causes:
No SIM card inserted or inserted SIM card is damaged
Inserted SIM card not positioned well in such a way as to make contact with the corresponding contact bridges on phone.
Phone locked to a specific network and can only work on other networks when the firmware version is "flashed", that is completely changed to an unlocked version.
The phone might be faulty (try with another good SIM, if you still get thesame message and its not one of the above reasons... it might be a transciever problem or the phone's SIM card slot's pins might be defective).

This problem is due to your phone's sim card IC malfunctioning. It may get damaged due to phone dropping gently into rough surface and its crystal structure may break due to it.
