Speedfusion Connect support for older Transit modems?

The article on Speedfusion Connect lists only the “MAX Transit Pro E” under Transit modems, though want to know if older modems like MAX Transit Duo having firmware 8.1.3s152 build 5295 or later will also work/eligible for Speedfusion Connect?

The new model Transit Pro E has an esim which allows this.
This won’t be possible on the older transits.
