Hello,
I am unable to make calls via WiFi. I have a Galaxy S3, and I recently received a replacement phone from insurance (due to an issue with my charging port). I've only been using this phone since yesterday. Since I got it, I have an alert "Error: REG90 "Unable to Connect""
I have full WiFi signal, and I have tried the instructions listed in the trouble shooting page: Wi-Fi Calling troubleshooting for Android. Still no luck.
Can anyone else help me with this? I have very poor signal in my house, and WiFi calling makes that much less frustrating.
Thank you,
Jessica
