Semtech AirLink: How to Configure APN

If your Semtech AirLink cellular device is having issues successfully establishing a connection to the cellular network, it may be that the device's APN (Access Point Name) value needs to be appropriately configured. The APN value is assigned to the SIM card (line of service) by your cellular carrier.

Note: If you're unsure what APN value is assigned to your SIM card, please contact your cellular carrier to obtain this information before proceeding with the following steps.

Configuring APN settings:
