Pixel 4a 5g, when call quality indicator is HD or HD+ no one can hear me, but I hear them!

Confirmed with three callers today. They are unable to hear me but I can hear them crystal clear.

Edit: I just turned off 5g and turned on 3g and voice works perfectly! What the heck is going on with 5g? 

I noticed for the first time yesterday HD+ was indicated in the Google phone call screen, I've never seen that before. I've seen HD but not HD+. May be a coincidence, but maybe not...

No matter what I try, including using a headset or speaker, no one can hear me. This rules out its my phone's mic, as well I can record sound clips just fine. It's got to be the network...

Does anyone have experience with this? I tried to turn off VOLTE to fix the issue, but that's no longer an option.

As I said I'm on a pixel 4a 5g and I'm using eSim. 

Desperate for some help.

Thank you!

It's an eSim I don't have any other phones that support eSim unfortunately.

I just turned off 5g, and switched to 3g, and voice calls work. So it must be volte causing the issue, frustrated because volte worked on Bell just fine.

Thoughts?

@Hewis  Can you try the sim card in another phone to test . And then try a known to work SIM card from agreed or family in your phone to test ? This way you can rule out if it’s device issue or account issue . But my gut tells it gonna be a device  settings issue
