Yeah, I scoured the internet and the forum looking for solutions; unfortunately I live in a little bit of a remote area in NC where tower coverage doesn't support other carriers than mine, and none of the work-rounds worked for the one carrier that works around me. I've reached out to my carriers support, as well as F(x) and we can't get it working even with a mule phone and sim. I'll have to wait to buy another when I can swap carriers, hopefully next year. I was really looking forward to using this phone too!
