AT&T WiFi Calling Now Available for Some iOS 9 Users

This is a carrier feature first, so I'm not sure how Android could have this for years if the carrier didn't support it.
The only people I've noticed trying the 5S 5C or 5 haven't had much success
Seems in general the feature favors 6 or 6+
Even for T-Mobile's version reports and comments and the general consensus is 5S or older Apple devices and non Apple devices are iffy/spotty
Who here cares about Android unless
A) You're a fandroid
Or
B ) You're a crapdroid owner on a Network that had support or framework before now
The point is it's rolling out now
Quick note this morning involving Emmergency calling
Had a situation arise where I had to call 9-1-1
Despite filling out/agreeing to the 911 thing call forced me to switch from WiFi to my spottier cell network coverage
So much for this being possible/useful in dire situations
Luckily my cell coverage barely managed the call to address the attempted break I had earlier

I'm thinking either ISP related or NAT related, I don't enable uPNP as outbound dynamic NAT should be enough, assuming they are using TCP to establish the initial tunnel. Anyone else enrolled but not able to use the service?
For those of you wondering why it seems limited to VoLTE areas (for handoffs) and otherwise is somewhat limited, here's the answer: http://www.phonescoop.com/articles/article.php?a=16191
Essentially, AT&T needs to get a waiver from the FCC to allow unrestricted call routing over WiFi due to the inability of WiFi to transmit TTY signals for the hearing impaired. AT&T has a newer service in the wings (RTT) that does work over WiFi, but its not ready for primetime yet. The waiver would allow calls to be routed over WiFi notwithstanding the lack of TTY service.
Fingers crossed that they get this, though its definitely a good sign that they've been able to roll this out for the iOS 9 beta. I haven't been following the Verizon side of things, but I'm sure they have the same issues.
Also, am really hoping that this will work and work well for the iPhone 5s. I have terrible cell coverage at home and was counting on this to help, especially since I have a house full of 5s's.

I don't believe they are going to charge for it. However, it says in the terms and conditions that if you make a call outside of the United States using wifi calling, you will be charged as though you are using cellular signal to make an international call.
Just put your phone into airplane mode, and turn your wi-fi back on. That worked for me to trigger wi-fi calling in Northern NJ. However, my problem was the other side couldn't hear me for some reason. Have to try it out with more people I guess.
Really? T-Mobile treats Wi-Fi calling while abroad as if you were in the US, so calls to US numbers (and international numbers, if you have that as part of your plan) are still free.
Keep in mind that iPhone 6 and 6 Plus CANNOT access the new low band 700a MHz spectrum that TMO is deploying. If you had an LG G4, Galaxy S6, or another device that DOES support 700a, you'll find improved/stronger coverage and building penetration in a helluva lot more places than you will with an iOS device. So it isn't fair to say "T-Mo sucks!" when using a device that cannot fully utilize all network bands deployed. However, their entire footprint isn't 700 (yet). Hopefully, Apple will include 700a support with iPhone 6s. Current iPhones already support 700b and 700c.
@ StevePJobsFan
There are STILL plenty of reasons T-Mobile sucks aside from that. Existing infrastructure could still be improved and use said improvement
Also TMO CS could be better, they could not try to scam ( some ) customers into paying excessively for SIM cards even when they give out a defective SIM
( yes this has happened )
And I could rant on and on about them but I won't. I'll continue to prefer iPhones on AT&T more so once WiFi calls are improved and/or fully rolled out. Hopefully other meaningful features or improvement down the road too
( like Data Rollover of more than 1 bill cycle )

Wow, that's a good point I hadn't even thought of. I have the international version of the iPhone with the additional bands. Does it have the 700a frequency?
I have the MG4C2LL/A Unlocked (not the T-Mobile unlocked) that came out in January 2015 in the US. From the looks of it, I don't think it has the bands. It looks like it has all the TMO bands plus the TD-LTE bands for china, but just 700b and 700c. Darn.
I guess I can't say their coverage sucks, but considering they're advertising iPhone like there's no tomorrow, they're setting themselves up for the perception of poor service.
Hey just wanted to update, I was now able to access wifi calling Houston TX suburb area. It asked me verify my 911 calling location and I was able to activate.
I'm in the Chicago area, says not available in our area yet though which sucks, I work in Kenosha which has absolutely horrible service, if any at all, and I will loooooove when this comes out!
Actually, I just tried it and now it's giving me a different error message, it says to enable WiFi calling on my account to contact my carrier. Hmm.
Just wondering, will changing my address to a New York address make it work, or is it location/GPS based?

Best as I can tell from my set up and others the biggest Keys are:
Have a compatible plan
Compatible account type
Account in good standing
And decent compatible WiFi Source
Being an an HD Voice coverage area seems to be reccomended but some claim they are getting/using AT&T WiFi Calling without it I doubt changing addresses would work
In theory though changing of your phone number or traveling somewhere where it is work might work if you're really desperate to get onboard with the Beta
