Hello, my wife and I have both had OnePlus3T GSM android phones for over a year with no issues. For some reason my wife had her Visual voicemail disappear about a week ago and mine just disappeared yesterday. We did not change anything on our phones, it just vanished at the same time ting sent us a voice mail setup call. While trying to figure it out, from the dialer menu, I went into:
settings--->call settings--->SIM 1 (Ting)---->Voicemail and it shows visual voice mail as turned on. I have tried rebooting it, turning it on and off, but nothing worked. I did set up a regular ting voicemail in the mean time. Any help would be appreciated.
Phone is on: Oxygen 4.51 (updated to new version to see if that would fix it.
