Just two SIM cards? The TV broadcast guys I had worked with usually had something like four different SIMs in their broadcasting backpacks – network congestion at crowded venues or public events can degrade them quite a bit, and while nowadays telcos might often share the same backplane infra in the cities here, there is still something to be said for having more options to connect to, especially when the connections are marginal. But of course, the tech might have moved on since then, it's been almost a decade since I worked with them.
4 sounds like a bit overkill honestly, but maybe worth considering. We use the first responder 'reserved' bands like AT&T FirstNet. most of the time we get priority traffic, but if needed it flips over to the backup. If we really don't have cell at all, we just flip over to 800Mhz or VHF for comms anyways.
Ah, I see. First responders is a different matter. Broadcast TV uses lot more traffic, and doesn't cope that well with interruptions, so I guess it might indeed be over kill for you. I'll go get my coat and switch to read‑only on this channel, since US radios for 1st responders and your use is way beyond my ken.
Yeah, our traffic isn't usually media heavy, just constant GPS data and comms are our primary needs. For us its more about maintaining a steady connection then it is utilizing the full bandwidth. I appreciate your input!
