How does the travel router differ from an Android mobile hotspot, it can work over USB, Wi-Fi, and Ethernet if you have an adapter, you can configure a VPN on it and have hotspot clients use it, and it's always ready with a cellular or Wi-Fi connection
I also hear about travel usecases for these, even for devices with wireless which I don't understand.
Some cite security, which I don't understand. Which device's security depends on the network to provide security? Are they weak on 4G?
Some cite avoiding captive portals. Are they that annoying that it's worth maintaining and carrying a travel router?
I trust this is just my lack of imagination. Please enlighten. :)
