Haven't gotten the update yet either.

Update received overnight and installed this morning.
Find the app in the app list, run it.

Intro screen,

terms of service screen,

e-signature.

Then you have to turn the toggle on, select and add each Wi-Fi network individually, and assign a 911 address to each of them.  (You can do this by a "current location" button.)

It also adds itself to the connections menu so you don't need to use the app icon.

New Wi-Fi calling icon

Seems to indicate you have set up the current network for the service. Blue and white icon in the systray.

In a call it says "Wi-Fi call".   A similar all blue icon displays above that text.

See image.

Signal check also indicates that it sheds you off the system completely. No cell connect. LTE disconnected, ehrpd via Wi-Fi takes over.

 

Seems to me that it is effectively making any wireless network capable of being an Airrave?

 

I'll have to play with it some more, but I suspect that since it is using ehrpd, it is also capable of voice/data simultaneously.  I'll see for sure when I get home again.

It appears Sprint is doing a slow roll out on this update. With how few S4T phones that are out there, I assumed this would be quick. Apparently I was wrong.

Yes. Verified. I connected to a call and could surf normally. I did notice a bit of audio degradation but it was still comparable to a normal rural call quality.

 

This should open the door to VoLTE.

I got the update overnight but every time I click on the wifi calling app, it goes into a device self service screen, and then says it can't activate and I need to take the device to the nearest Sprint store. Any ideas? I tried to restart but that didn't work. I also tried clicking on the app with wifi on and off.

Take it to a Sprint store.  I suspect something got boogered up in the install process.

[Galaxyguy]

I called customer service and they couldn't figure it out. I even did a factory reset and that didn't work either. I guess I'll have to make a trip to the store today.

The Sprint forums are saying to call Sprint and have wifi calling activated-couldn't confirm because I'm waiting on update for regular s4

Strange.  I didn't need to do that.

 

My setup went flawlessly and I didn't need to do anything other than follow the on-screen instructions.

 

Must be something was already set correctly on my account.

I have a 720T S4..installed the WiFi Calling the morning it was released. It works perfect. You mentioned the WiFi calling failed to initialize. Most of the time, I have no problems, but every once in a while, the S4 won't register a WiFi. From what I gather, it depends on the WiFi router. I haven't figured out a pattern yet. Once I do, I will post.

After going to the Sprint store and since they had no idea what to do, they called a high level tech support. That person told the store employee it is a "provisioning" problem and it may resolve itself later but they couldn't provide any additional help. To be clear, as soon as I open the wifi calling app, I hit proceed and then it won't go any further. It tells me to go to a store or call customer service.

The provisioning should have happened right after the WiFi calling update was applied. Personally, I would wipe the S4 clean...have the network re-provision your device.

I did a factory reset. That didn't change anything. I wish I would've known ahead of time because it would've saved me 2 hours in loading everything back on my phone.

Type this from the dialer, before wiping: ##72786#

 

It resets your network settings and profile.

Your device isn't rooted and never has been, right?

Log into your account. Does SPRINT show WiFi calling as a feature on your line?

 

Sent from my SPH-L720T using Tapatalk

The store and Sprint customer service confirmed it's active on my account.

 

Sent from my SPH-L720T using Tapatalk

That means your account is provisioned. Its probably the router. Try a a few free wifi that don't require a browser login. Some routers need SIP enabled on port 5060 for wifi calling

They tried the router in the store and it didn't work there either. I can't even get to the screen to accept the terms and conditions. I doubt it even matters at that point.

Other than wifi calling not working for me, I also noticed the Sprint Zone app is messed up. It shows up as Mobile Zone with an Android character. When I click on it, it doesn't do anything either.

Sounds like your phone might be defective. Where did you buy this phone? Sprint Zone always works on Sprint smartphones.
