Resolving No Signal Issue on iPhone, Searching Error
1. Restart Your iPhone.
Restarting the iPhone, while a simple method, can often be the most effective as it resets the device to normalcy, fixing minor issues like inability to connect to Wi-Fi, loss of 3G signal, or network signal problems. If you've restarted your iPhone multiple times and the searching error persists, you may need to apply more complex measures, as shared by Mytour below.
2. Clean SIM Card Slot
If the searching error occurs frequently but then resolves on its own, the culprit may be the SIM card. To ensure, remove the SIM, clean it, try it in another phone, and then reinstall it in your iPhone to reevaluate.
3. Enable Airplane Mode
Activating airplane mode on your device is the easiest way to address the no signal issue on iPhone. In this mode, all network services like Wi-Fi, 3G, Bluetooth are turned off. To activate, swipe up from the bottom of the screen to access the Control Center, then tap on the airplane icon displayed in the top-left corner. After switching to airplane mode, wait a few minutes, then deactivate airplane mode by repeating the same steps.
4. Check Date and Time Settings
5. Adjust Timezone and Time Settings
Sometimes, switching to a different timezone or having incorrect date and time settings can lead to the searching error on your iPhone. To avoid discrepancies, choose the automatic mode. To switch to this mode, go to Settings > General > Date & Time > Set Automatically.
6. Change Voice and Data Mode
Changing Voice and Data mode is another way to fix the searching error on your iPhone. Go to Settings > Cellular > Voice & Data. If your device is connected to 3G, switch to 4G and vice versa. After completion, press the Home button to return to the home screen.
7. Reset All Settings
iPhone signal is related to the baseband, the baseband frequency that helps in receiving network signals. If there's an issue with this part, your iPhone will have no network signal.
