I've got a galaxy S7 EDGE on Verizon and a 5x on fi. After 2 months of testing fi, i can say that the service is absolutely as good or better than verizon. So my question is, can i use a fi data only sim card in my S7 edge? I'm inclined to think that since fi operates on both gsm and cdma, it might work. I wouldn't be able to make or receive calls, but could use everything else. Has anyone tried it? I also read that you can actually make calls on a data only sim using hangouts dailer. How about sone feedback?
