Dual-Path (Broadband + Cell) is the exclusive UL Listed (UL 864) configuration as of July 2026. Dual-Path configuration automatically selects the network carrier for a single cellular path between the two pre-installed SIM cards (AT&T or Verizon).
* Sole path options available at installer discretion, pending UL Listing.
The Dual Cell configuration (to be available at a later date) will provide simultaneous communication paths over each carrier SIM.
Note: SIM cards cannot be switched between the physical slots since each slot is programmed for a specific carrier (AT&T slot 1, VZ slot 2).
