I posted this same reply somewhere else on here.
Get the $55 / month service through Straight Talk which uses Verizon's network. Starting at this price point it is absolutely unlimited 4G LTE with no throttling. Some of the Android phones that Walmart sells (maybe all, I'm sure about that) do not allow tethering (hot spot) functionality. So to circumvent this issue you download PDA Net+ from the app store onto the phone and get the client app for your PC, Laptop or tablet. Once setup you can tether your devices either via WiFi or USB cable to the phone and use it as a hot spot. Many similar apps you have to do hacks on the phone in order to accomplish this but with PDA Net+ you do not, but you do have to place your phone into developer mode which is prompted when you start the app and explains how to do it. It's very straight forward and does not cause issues. Now, the app does limit your usage but all you do is restart the phone side app and away you go again, I think I used it for about 3 hours before having to restart the app on the phone. If you pay the $7.99 fee it will unlock the app for unlimited run time. I've had good success with this method and avoided the need to spend more $$s on another expensive hot spot device and incur more monthly fees. Just note though, if you are somewhere with a weak cell signal you will still have to get a booster, there is no getting around this for any phone no matter who the provider is. All I'm saying is that you can get inexpensive internet across all your devices using the PDA Net+ app. Hope this helps.
