Having all the same issues as reported in this thread and tried all the suggestions the issue still exists. There is no good way to use volte. The option seems to be dropped calls or 3g.
I've been having the same issue. 3g the calls work completely fine volte dropped calls or can't hear the caller. Support has been unable to help. This has been going on for months so leaving volte for a few weeks and coming back has definitely not...
