Wifi calling had already been deactivated on both devices when she called. Hers never showed "hd attempting"? Is it possible she could travel for 30 miles and never hit a hd voice tower? I had to get rid of the wifi calling to use my sprint phone number as my google voice number. I haven't tried to re setup the wifi calling since i started using google voice for my sprint number. Not sure it would work.
I tested it out in Winston Salem, NC and still nothing. Changed towers at least 8 times and still no HD Voice. Cant figure it out
Thanks for staying in touch with us linkford.
It appears that my google voice was the problem with the hd voice. Didn't learn till today that it will not work while Google voice is active.
Going to test it here in about 10 minutes to see. I now have google voice deactivated too. I will make a post if it works with it off, and make this a solved chat.
We tested while my girlfriend was heading home. It appears you can only have HD voice when google voice and wifi calling are disabled. HD voice will not work with either one active.
