6 Solutions for Phone SIM Recognition Errors
Phone SIM Recognition Issues
1. Restart Your Device
When your phone restarts, it refreshes most of the software, ensuring that minor glitches can be resolved. So, restart your device, reconnect to the network, and check if the device detects the SIM card.
2. Check the SIM tray
You can also power off the device and remove the SIM card to check. Often, dust buildup causes issues with contact between the SIM and the internal circuits of the phone. Blow away the dust from the SIM tray, gently wipe, reinsert the SIM card, and power on the device.
If the issue persists, try inserting a different SIM card into your device. If the SIM card is damaged, you'll need to contact your network provider.
3. Switch to Airplane Mode
Once you're certain that the issue isn't with the SIM card, try enabling airplane mode on your device, wait for about 30 seconds, and then turn off airplane mode. Your phone will attempt to search for networks, and the problem may be resolved.
4. Switch Network Mode to Automatic
Sometimes, your network mode may be incorrectly set, causing issues.
- Go to the Settings menu;
- Look for additional networks under Connection.
- Next, tap on Mobile Networks.
- Tap on the Network mode.
You'll receive a pop-up menu with various options; select LTE/WCDMA/GSM (auto connect).
5. Choose the appropriate network provider
If the network selected on your device doesn't match the one you're using, you may encounter the phone not detecting the SIM card error.
6. Restore to factory settings
After trying all the above methods but your phone still doesn't recognize the SIM card, you can restore your phone to its default settings. Resetting the device to factory settings can help resolve most software-related issues. Remember to back up your data before proceeding. Refer to how to restore Android factory settings here.
Other Causes When Phone Doesn't Recognize SIM Card
If you accidentally drop your phone in water causing it not to recognize the SIM card, there's a possibility that one of the circuits is damaged. It's best to let the phone dry completely before using it. Remove the device's back cover, take out the battery and SIM card, and let it dry for 24 hours before reinserting.
Additionally, software updates can also be a cause of the phone not recognizing the SIM card (due to outdated data). For this issue, restart your phone to see if the problem disappears.
