Totally feel you on this. I’ve been in the same spot, hopping around and praying the Airbnb Wi-Fi holds up 😅 And yeah, tethering drains phones like crazy too....
I’ve personally tried a few hotspots over the years. The Netgear M6 has been decent for me as they don't have their own eSIM system like many do, and you can use your own (you just buy a cheap local SIM and you're done).
The Solis Lite (used to be Skyroam) is another solid one for global use, but data can get pricey if you're not careful.
In case you are interested, we actually wrote a guide on the best mobile Wi-Fi hotspots we came across, what works, what sucks, and what to avoid.
Curious what others are using too. Has anyone found others that are worth trying?
