Troubleshooting Cellular Connection Issues

If you are unable to connect to cellular using Portal3, check for these issues:

• One or more of the target APN settings are configured incorrectly.
• Cellular signal strength is poor.
• The SIM carrier’s network is not available or experiencing an outage.

APN Settings

To confirm that APN settings are configured correctly: 

1. Review APN settings and configure if necessary. For guidance, see Configuring APN Settings Using Portal3.
2. Ensure that the MCC and MNC of the selected APN match the MNC and MCC of the SIM card.
   

   NOTE: You can check the MNC and MCC of your SIM card by sending the get_apn_settings command in the Canvas' command terminal.

3. If needed, check with your provider for help configuring an APN.

Poor Cellular Signal Strength

If signal strength is -100 dBm or less, it may be difficult to establish a connection. WiFi is recommended for areas with low cell reception.

Network Unavailable

Sometimes network issues can prevent a Canvas from connecting via cellular. The network may not be available, or you may have reached your data usage limit. Check with your network provider for possible outages.
