Odd, I have a 928 on Verizon and haven't seen this even when traveling internationally. Presuming you've upgraded to Amber? Looks like Lumia Black is still pending approval for the 92x phones in the US: Software update for Nokia Lumia with Windows Phone 8 - Nokia
Could be a fix buried in there
T-Mobile suggest this
No signal while Wi-Fi Calling is turned on: Nok... | T-Mobile Support
Are you set to Wifi Preferred already?
sound more like the problem post #6
Wifi calling issues | T-Mobile Support
Only t-mobile has WiFi calling so I don't think you can have this problem.
Only T-Mobile have wifi calling? Can someone confirm this..?
PS sorry for bumping an old thread but I was just going through some older topics to do some research on the L925 and came across this.
Full Skype integration, if that works for you.
You know, it's not really that hard to find this information, just search in the store, there's a Viber app right there. I suggest Skype because it's integrated into the phone, much like iPhones talk.
Dude, no, Skype and Viber are WiFi calling protocols, so the ultimate answer is no.
No as in it won't work on my L925 because of my At&t carrier or no as in the guy who said wifi calling is only exclusive to T-Mobile is wrong?

WiFi calling is a T-Mobile feature which allows you to make and receive calls and texts on your mobile number while connect to a WiFi network even if you have no cellular signal. It has nothing to do with apps like Skype, those will work on any device\carrier.

I'm not sure why you don't understand what I wrote and I'm not sure how else to explain it too you. Maybe you should watch some videos. About Wi-Fi calling | T-Mobile SupportSure it does, you don't need a carrier specific plan to have wifi calling. You can use Skype for wifi calls on any provider.
No you can't. You need to use an app like Skype. The purpose of T-Mobile WiFi calling is to allow the phone to function the same on wifi as it does on cellular. Meaning you can make and receive calls and text exactly the same even if you have zero bars using the phones dialer... no need for third party apps.Why i don't have T-Mobile and can use wifi to call anyone I wa t too.
