It's not like the wifi calling is working right for some people anyways. The new international wifi calling update broke the gps on mine and my s4 isn't the only one broken. Sprint sucks.
Can't get reliable service at home, Airave messes up my Internet and switched to sprint because of work and wasn't aware of spark phones. The store dumped an old S4 on me and after I realized what happened the 14 days had expired. Thanks to the corporate employee there. So I'm not disappointed, I'm DISGUSTED!
is the Kyocera a tri band device?
I was sold a non tri band S4 while tri band S4's were in stock and then repeatedly lied to by staff when I tried to rectify - now ne reception at home and Airave crashing my system - anything less than a tri band S4 replacement - which I have tried to do numerous times - nothing can be done
