If your terminal device isn’t working as expected, you can try the troubleshooting steps mentioned here to fix the issue.
Problems with 4G or wireless network
When you first activate the terminal, you need to connect it to a wireless network like a phone hotspot. We recommend using a wireless network when possible, as this is usually more stable than a 4G connection. You can also try connecting to a 3G network.
Connecting a terminal to a 3G network
- Tap on the home screen 3 times.
- Enter your passcode.
- Go to Internet > Mobile settings.
- Tap Advanced.
- Under Preferred network type, change the setting to 3G/2G auto.
Switching the network type to 3G and then back to 4G may sometimes help improve 4G connectivity on the device.
“Callback service not found” error message
To resolve this issue, you can try turning on and off Airplane mode on the device.
- Hold the power button until the settings menu appears.
- Turn on Airplane mode.
- Hold the power button then turn off Airplane mode.
- If the issue continues, hold down the power button for 10 seconds to reboot the device.
