The “No Service” issue on your Samsung A14 5G could be caused by a variety of reasons, ranging from software glitches to hardware issues. Here are the steps to troubleshoot and resolve this potential issue:
- Restart your device
Sometimes, a simple reboot can fix a temporary network glitch. - Check Airplane Mode
Make sure the Airplane Mode is turned off, as this disables all network connections. - Update carrier settings
Go to Settings > About phone > Software information and check for any available updates for your carrier or network. - Update software
Go to Settings> Software update to make sure your device’s software is up to date. Updates can fix known issues. - Reset network settings
This will reset your Wi-Fi, Bluetooth, and cellular settings. Go to Settings > General management > Reset > Reset network settings. - Check your SIM card
Remove, clean, and reinsert your SIM card carefully to make sure it’s seated properly.
You can also try another SIM card to determine if the issue is with the card itself. - Select the network manually
Go to Settings > Connections > Mobile networks > Network operators and turn off Select automatically. Then select your network manually. - Check for hardware issues
If the device has been physically damaged or exposed to water, the antenna or internal components may be damaged. In this case, professional repair may be required. - Use a signal booster or move to an area with better coverage
Poor network coverage in your location may be a factor. Try moving to a place with a stronger signal or consider using a signal booster if available. - Factory reset as a last resort
If none of the above steps work, consider performing a factory reset. Back up your data first, then go to Settings > General management > Reset > Factory data reset.
