It really depends on your needs. If you are just traveling in your van or have a mellow job and don't mind not having internet all of the time, then using your cell phone for internet or as a hotspot is the cheapest, easiest solution. It doesn't cost anything beyond your normal cell phone plan and is adequate for using all of the apps you need as a van lifer. If you need a strong signal when you are far off the grid or are working full-time from the road, then Starlink is going to be your best bet.
