To ensure you have an active internet connection, it is crucial to verify your network coverage. Check if you are within the service area of your cellular provider. If you are in a remote location or an area with poor signal reception, this could be the reason for the connectivity issue. Try moving to a different location or searching for a Wi-Fi network to establish a stable connection.

To disable Airplane Mode, access the device’s Settings menu and locate the “Network & Internet” or “Connections” section. Disable the “Airplane Mode” toggle to restore wireless connectivity, allowing you to access cellular data.

Verify if mobile data is enabled on your device’s network settings. If disabled, follow these steps to activate it:
- Navigate to “Settings”.
- Select “Connections”.
- Tap on “Mobile Networks”.
- Toggle the “Mobile Data” switch to the “On” position.
Once activated, mobile data should be accessible on your Android smartphone.
