Might be worth to pick up a data hotspot device at a truckstop or order one online. Try to get verizon device, you dont have to get a new cellphone. They also have little usb devices for hotspot you can plug into your laptop for your devices. Check online or stop at one of those phone stores at a petrol or something. Will prob run you 40 to 50 bucks a month.
Have a Samsung Galaxy 7 pre-paid that i ordered online (Best Buy, I think). It has the settings to do a hotspot . But won't let you use it.
Zte mobley device is an att prepaid. $20 unlimited if you can find one besides ebay. Its only 2.4 gigahertz though. So expect an average of 5 - 10 mbps. 25 if you got a good signal. It drops to 1.5 in my house but still streamed netflix and directvnow.
Cricket's unlimited says they "might" throttle you after 22GB under certain conditions. I've had cricket for over a year and I've never been throttled. A couple of months ago I hit 160gb in one month.
