No 512 GB Ultras

Sammy just confirmed my order, so they must still be available.

VoLTE is working fine on AT&T on my unlocked S20+ and Ultra. The only thing missing this go around is wifi calling.

Just received my unlocked Ultra. Put in my old ATT SIM. No VoLTE available. Is there anyway to get it working?

I seem to remember some discussion about this a while back, but haven't figured out how to search for it in this forum only.

Are you sure it's not working on its own?

How to tell if it is? The switch under Connections is not there.

This is why I do not buy unlocked for AT&T. You could try flashing the AT&T firmware if worse comes to worse. Everyone, and I mean EVERYONE is sold out of the 512gb Ultras for AT&T.

On Verizon it shows under Mobile Networks which is one menu deeper. Not sure about ATT but I'm sure someone out there has it.

It's not on mine. Maybe I should start a new thread dedicated to this. OK?

There is also no Network Mode showing, as described in this article: https://www.androidcentral.com/how-disable-5g-samsung-galaxy-s20

Seems to be lots of stuff missing on unlocked phones with ATT.

Thanks Mike. Can you point me? I haven't figured out how to do a Search that only covers this forum instead of the entire website.

Actually the one I'm thinking of may be about the S10 which may not be applicable if the S10 was added to their list of Volte devices

That's the one.

After reading through it, I called ATT to update the IMEI, which took forever. After it was supposedly all done, I received an email that the tech had restarted my plan effective today's date; and this raised the monthly cost

After 30 minutes on hold for a second tech, I was assured that the email was computer generated; and my plan had not been changed.

I guess I'll see what I shall see.

Still no VoLTE showing up in the Settings.
