So yesterday I found out the Note 5 doesn't work with my Airwave

I have poor signal at my house and have used a airwave for a few years. After my wife got the S6 she had trouble receiving calls in the house. I called sprint a few times and just kept thinking her phone needed a upgrade. After getting my new Note 5 I started having the same trouble (Note 3 was fine ). Calling Sprint they told me the airwave wont work with the new phones that these models have a "Built in" airwave. WiFi calling but neither of us had it on. You have to go into settings and turn it on. It will go through and a configuring update> pull in your home wifi> reboot. Then it will auto connect. There was a short cut in the top icon pull down window that I never even paid attention to before.

If your having trouble receiving calls at work or Home give it a shot.
