I've carried around these GLINet devices for years. Their lifesavers. Especially if you're traveling with other people. Everybody can figures their device to use the GLI net Wi-Fi, which tunnels traffic, and then set it up in a hotel room, or an Airbnb, and your networking just works. You don't have to configure each device.
Nowadays however, with caylex I'm able to do 99% of what I want to for a travel router, with just my backup cell phone. So I've stopped carrying the GLINet devices, instead I just bring a USBC Ethernet adapter to check on my backup phone. I still love GLINet, I just want to minimize how much I have to carry.
