We bought Starlink for mobile use. Around half of the places we like to go are either full or do not have service.
Places near recreational homes (even with wired internet and cell service) are full.
Remote places with few to no users do not have service.
For a month I've tried switching to 2 locations that are full without luck. My advice is don't change your location if you need the service.
Edit: I was just on Starlink. A cell that I could switch into and out of 3 days ago is now full. With 5,000+ being shipped/week it's going to happen more often. If it gets down to 1 out of 3 cells we want to use are full we'll go with another satellite system.
