Is this a viable way of testing things out? I am currently running a rapidly failing Moto X that will need to be replaced before spring, and have been looking at coverage maps frequently over the last year. I am aware that CDMA is probabl;y going the way of the dodo and even see threads here about that. T Mobile has an interesting thing with rapidly increasing coverage in areas I go. This device seemingly has no risks. Is it relevant to RW? I already am used to poor coverage because of places I live and frequent, so why not try something like this for free just to see what the difference would be?
