New LTE Booster works fine over Starlink
I can confirm that the new LTE booster, like the old 3g Microcell, works just fine on a Starlink Satellite connection.
Starlink has very low latency(23-30ms), better than a cable provider at another site I run, so I fully expected it to work unless it was explicitly blocked. I'm sure AT&T doesn't support it if you have problems, but it works just fine.
Tested incoming and outgoing: calls, multi-part messaging and MMS . All working.
I would not try it with Hughes Net or ViaSat as those have very high latency (600+ms) and if your on one of those you already know any VOIP service just isn't gonna work over those, and the new booster is no different.
Bonus, MMS messaging fully works now! The old 3g one on a Starlink connection, I could send an MMS, but receiving them didn't work, i just got a message that I had a message and it wouldn't come in until I got onto a real tower. No idea what that was, it wasn't the 3g MCell, as I had two others on cable ISP's and MMS worked just fine.
