The mobile phone shows that there is no SIM card, so you can't send text messages or call for help? urgent

Hello, landlord: Let me answer your question. I am also using htc's mobile phone, and I have encountered this situation. There are various possibilities.

One: there is something wrong with the sim card slot of the mobile phone, but there is no problem in restarting the machine. It is recommended to observe the sim card slot of the mobile phone to see if all the copper pieces protrude. If there is a dent, you can pick it up with a fine needle!

Two: the mobile phone card is dirty or slightly damaged. It is recommended to clean it with an eraser. Look before you use it!

Three: the mobile phone card slot is damaged or the mobile phone is damaged. Suggest to send it for repair!

Ps: You can find your mobile phone, put on a secondary SIM card and see if there is still this problem. If it still cannot be read, it can be determined that the SIM card is damaged. If it's still not good, I suggest you change it in the business hall! If you can read it, there is something wrong with the phone and it will be repaired!

Note: the cardholder's ID card is required for card replacement. Then remember!

I am glad to answer your question and hope to solve it as soon as possible!
