There are many users who use the V3 to connect to their phone via cellular hotspot. The difficulty is in the phone, not the cam. The cam will connect to any 2.4 Ghz WiFi it can see so long as you have the PW.
One user tricked the cam by setting it up on their guest network SSID names "phonenet"and then programmed their phone hotspot to be named “phonenet” with the same password. That way the cam doesn’t know it is logging into a different network. All that matters is the SSID and PW.
There are users who set it up on hotspot, take it camping, plug it in and initialize on hotspot, then leave it plugged in to do time lapse star videos. Others hook them up to battery packs and let them record like trail cams. One user described using it as a backup cam on their RV connected to the phone hotspot in the cab and live streaming the feed.
As long as you don’t turn the cam off, it doesn’t care where it goes. As a dashcam, it just can’t be turned off overnight, otherwise it needs it’s setup WiFi to restart.
Hotel WiFi is tricky because of the type of WiFi at the hotel and their login protocols. If the WiFi network login is URL portal based that sends you to a webpage to credential, the cam won’t connect because it can’t do that. If it is a guest network without a PW, you will have trouble because the cam needs SSID and PW. Users have gotten around this by using a mini travel router to connect to the the Hotel WiFi and connecting the cam to the Travel Router. That way, they only have to set up the cam one time to the travel router SSID and then just log the router into the new WiFi at each new hotel.
