Another Wifi option is at Walmart. The Straight Talk ZTE 288C 4G LTE Mobile Hotspot.
DO NOT GET THE ZTE Z289G.
The 288C uses Verizon towers. No contract, decent speeds where we have used it. Our phones are Net10 and the conditions of use do not allow the phones to be used as hotspots.
The only negative is that you have to call Straight Talk and ask how much data you have left.

We find it handy when we travel as it seems most CGs have crappy wifi.
