How to solve the problem that the mobile phone does not recognize the sim card?
If you use Unicom's SIM card, there may be the following reasons:
1.SIM card has poor contact with metal contact of mobile phone. I suggest you remove the SIM card and try plugging it in again.
2. The 2.SIM card does not match the mobile phone. I suggest you put the SIM card in someone else's mobile phone. If it works properly, please take the maintenance card and mobile phone to the mobile phone after-sales service provider to test the mobile phone. If it can't be used normally, it is suggested that the SIM card owner bring his valid ID card and SIM card to Unicom business hall for SIM card testing or replacement.
Tips: As the business rules of different provinces and cities are different, please refer to the local rules for details.
