iPhone 5s is not showing the wifi calling option for Verizon
I don't see the wifi calling option on my wife's iPhone 5s. Some places I read that the 5s can do wifi calling and others say no - it's a bit confusing. I've set it up on my iPhone 6s and my daughter's iPhone 6 and it works pretty good in our house where we have some problems with stable cell signal strength .
So the question is: Can an iPhone 5s do wifi calling with Verizon?
Thanks
