This would probably be a good time to bring up using one's own phone for WiFi calling, and query those familiar with how it goes (or doesn't) on SS, being careful to specify which ship - since it does seem to matter. I do know that I've had good luck on Celebrity ships using WiFi calling provided I was on their upper tier data plan, but that was a year ago.

You don't say where you'll be - what itinerary? If always more or less in sight of land, what you'll want is a cellular phone and plan to deal with GSM in Europe. At a minimum, you'll always be able to make calls while in port.
Attempts to video conference are going to be a function of both what ports SS blocks on their shipboard network and the bandwidth available to you. There's some chance that with the right VPN, the upper tier data plan, and not too much competition for satellite time, you could make it work. If any of the above sounds foreign to you, either get your IT folks on this for you or consider not using video.
