Assuming you’re talking “phone with hotspot”, I use an iPhone 5S on Tmo for this purpose. They are cheap and tethering works decently from them.

I also have a mobile hotspot, but the 5S works better. Our use case is a food truck type of setup.

I was thinking "hotspot without phone", if only for a possible battery benefit. But realistically, Android phones are already so cheap that they're probably the best option.
