I have used Starlink for almost 3 years. If you want to ensure you have something than can handle video calls, WiFi calls and uploading downloading a lot of data 99% of the places you travel, then Starlink wins hands down.
Now you need a relatively clear line of sight. Some obstruction can still give you adequate performance. We went to Alaska last year in a caravan. We had Internet and could make calls all the way through western Canada an Alaska.
After a few weeks of people in the caravan seeing us with access anywhere we stopped, about a half-dozen people asked me about getting it. I helped them order it and get it shipped to one of our upcoming destinations and setup.
I upgraded from the Gen 2 to Gen 3 hardware a few months ago and the wider field of view helps in areas with some tree branch obstruction.
Cell phone data plans can be found for less money...... but depending on where you travel there may be little or no coverage.... like our trip to Alaska.
I also have a Pelink 5G Router using a Basecamp 2.0 enclosure and the Winegard 360+ 5G antenna on the roof with two T-Mobile Sims that give me 30GB/mo each for $10/mo as an alternate source if we are going to be in areas with good cell coverage and I want to pause Starlink for a month or two, etc.
