Yup....mostly phones issued in the last few years or so. Verizon has 17 models, AT & T 23 models with WIFI calling. I have a Samsung S7 and it works great. If you are unsure just try it from home. Remember..you will also receive calls wherever you are when connected to wifi. As I said, my cell is ALWAYS on airplane mode at home...I just take it off when leaving the house....MUCH better call quality in my situation.

I just think it is a no brainer with near zero effort needed.
