Device not connected to the cellular network

The following basic troubleshooting steps resolve most cellular connection issues for a Connect Tank. You need physical access to the device to complete the steps.

If the basic troubleshooting steps do not resolve the network connection issue, use the CLI to get the status of your device and contact Digi Technical Support.

Verify SIM configuration

1. Verify the following for your device:
   1. Make sure the SIM card is inserted correctly into the SIM tray; see Step 3: Assemble Connect Tank.
   2. Make sure you are using the correct APN and that the PIN, user name, and password are configured, if required; see Step 4: Configure the cellular connection.
2. Contact your cellular service provider to make sure your SIM card is activated and assigned to a contract.

Check cellular antenna

• Make sure the cellular antenna is securely installed on the device and is not damaged.
• Verify that the antenna installed on the device matches the available network. For example, a 3G antenna may not work as expected when installed on an LTE-only device.

Verify cellular network coverage

Work with your cellular service provider to make sure there is adequate network coverage for the device installation area. If possible, do one of the following:

• Move the device to an area with adequate cellular network coverage
• Use a cabled antenna to move the antenna to get a better signal without moving the device
• View device information in Remote Manager
• Verify cellular network coverage using the CLI

Check battery life

Older batteries may not have enough power to connect to the cellular network and you may need to replace the battery. If Connect Tank has been deployed for some time, check the battery life. This can be done from Remote Manager or by using the CLI.
