Carrier-specific APN list (firmware 18.1 and below)

To configure a customized APN list that will connect an Accelerated device to non-standard APNs based off of the cellular carrier associated with the SIM card.

Note The Digi 6350-SR/6355-SR device has most commonly used APNs automatically programmed into its firmware. These APNs do not need to be programmed manually.

Setup

This article assumes that the the APN(s) being programmed in have been validated as the correct APN associated with an active SIM card. To create carrier-specific APN lists for multiple carriers, a new modem interface must be added and associated with the particular carrier.

The configuration steps described below covers how to assign a custom APN list to a configuration template in Accelerated View. It is important to keep in mind that the device connecting over a custom APN may require an alternative Internet connection (via its Ethernet WAN port) or a local configuration change before coming online to sync with its cloud template.

Sample

The sample configuration outlined below shows how to associate the default modem entry with one carrier (AT&T), and how to then create an additional modem interface associated with another carrier (Verizon). The custom APNs for each carrier are to be nested under the corresponding modem entry. While this example uses carrier detection to delineate between different APN lists, modem interfaces (and their associated APN lists) can instead be configured to specific SIM slots as needed.

Note You will need to know the custom APN for each SIM and/or Carrier. This is a sample configuration specifically utilizing AT&T and Verizon SIMs. Any other carrier SIM cards will not match this connection and will need to be configured with the corresponding Carriers and APNs.

  1. Under Modem > Custom APN list, select the checkbox next to Enable.
  2. (Optional) Selecting Override, also nested under Modem > APN list, sets the device to exclusively attempt to connect using the APNs specified per the custom list. If left unselected, the custom APNs will be added to the start of the standard list of APNs.
  3. Click the Add button to create a new APN entry for the list.
  4. Enter a designation for the entry using the Label field. This does not have to match the APN
  5. Specify the intended APN.
  6. Select the Carrier from the corresponding pull-down menu.
  7. Create additional APN/ Carrier associations as necessary.
  8. Click Save to finalize the changes.
