I find myself with a need to be able to send data log files and receive tune files through email from a Windows capable device while on the go from my truck or away from home. I've searched the web, but all the info I find is old. Can we tether to mobile phones on straight talk? I use an lg g2 right now with att service, but will need a new phone soon. I'd like to just buy a ST phone from wally world, as they are getting better and better, and I've had terrible luck with big brand name phones from eBay. But I gather that it will be more difficult or impossible to use a ST brand phone as a hotspot. What are my options these days?
