The solution to the problem that the Xiaomi smartphone cannot recognize the SIM card
Since SIM card recognition issues can be easily confused with signal issues, it's important to identify the specific problem before proceeding.
1. Check if the IMEI status is normal
Enter "*#06#" on the dial interface to view the phone's IMEI number. If the IMEI is missing, it's recommended to visit the after-sales service center for testing.
2. Check if the SIM card status is normal
(1). Enter "*#*#6484#*#*" on the dial interface to access hardware testing, and select SIM Card to see if the SIM card is inserted;
(2). If it shows no SIM card or the SIM card is not inserted, try replacing the SIM card. If the SIM card still cannot be detected, it's recommended to visit the after-sales service center for further testing;
(3). If the SIM card is detected after replacement, the issue is likely with the original SIM card. Visit your carrier's service center to replace the SIM card and try again.
3. Reinstall the SIM card
1. Ensure the SIM card chip is oriented correctly according to the illustration on the SIM tray;
2. If the SIM card still isn't recognized, remove it and clean the metal chip area with an eraser or alcohol, then try again.
If none of the above methods resolve the issue, it's recommended to visit the after-sales service center for further diagnostics.
