Troubleshooting Steps to Resolve SIM Card Registration Issues

1. Restart Your Xiaomi Redmi 12

A simple restart can often resolve minor software glitches that may be interfering with SIM card registration.

2. Check SIM Card Placement and Condition

Ensure the SIM card is properly inserted into the designated SIM card slot. Inspect the SIM card for any signs of damage or dirt. Clean the SIM card gently with a soft cloth if necessary.

3. Switch Airplane Mode On and Off

Enabling and disabling Airplane Mode can refresh your phone’s network connection and potentially resolve registration issues.

4. Manually Select Network Mode

Go to Settings > SIM Cards and select the appropriate network mode for your location. Try switching between LTE/4G/3G/2G modes to see if it helps.

5. Reset Network Settings

This will erase all saved Wi-Fi passwords and network configurations. Go to Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth.

6. Update Phone Software

Check for available software updates. Go to Settings > System > System Update. Installing the latest firmware can fix known bugs and improve network stability.
