We commonly use Balance 20X with a flex module. This gives disparate links as you have a CAT-4 and CAT-12 modem. If you are really trying to optimise this can involve asking engineers to move sims between the internal slots and the flex module.
Would a better solution be to allow us to utilise remotesim to use any installed sim on any modem? Would save many lost screws!
I’ve tried enabling auto discover and 127.0.0.1 as the server IP but no dice.
