Curious about 5G and the best modem to use? Read this technote


These modems have been tested on ACCESS 4.0p5 and higher, and LiveShot 1.4.1p2 and higher:


The Verizon USB730L is the only current modem available from Verizon.  We do NOT recommend using this modem.

Comrex recommends our Comrex Connect Modem for use with Verizon networks.

The following modems are compatible but no longer sold through Verizon.

  • U620L

  • Huawei E392
  • Huawei E3276 *non-Hilink version firmware
  • Sierra Aircard 320U
  • Sierra Aircard 330U

Although not specifically listed, some other modems are supported as Ethernet devices only. This means they will appear to the codec as a simple Ethernet port, and should be pre-configured to auto-connect. Unfortunately, when using these modems, no connect status or signal strength info is available by the network manager within the user interface. It may be possible to see modem status on ACCESS by opening the integrated web browser and inputting the UI address of the modem, which is different for different models. It’s usually not possible to use more than one type of this modem simultaneously.
Some of the modems that work this way are:

  • Huawei E3272
  • Huawei E3372
  • Huawei E3276 with Hilink firmware
  • Most ZTE devices
  • Alcatel L800Z
