I have the Galaxy S5 and yes, the issue began immediately following the KitKat 4.4.4 update. The error message I receive states, "Unable to connect to a network. Please move to a new location and try again.
I have updated my profile numerous times and it changes nothing. I am still unable to gain access to wifi calling since yesterday's update.
@android_2112 Check if location is on (Gps) it seems like is an security update from 4.4.2 to 4.4.4 after im assuming you connected turn it off repeat if necessary
Updated to 4.4.4 today as well, and getting the same issue now with Wi-Fi Calling - Network Connection Error.
I have tried updating security, profile, PRL, location, restarted, etc..
I'm having the same issue Caveman. I try to manually update. Wait 10 minutes for the update to download, error out on the install. No luck. Please help Sprint
