    I agree. But like HD video, higher quality voice should be the minimum in the age where we are reaching 2Gbps speeds. Is that not a fair thing to ask for?

    As long as T-Mo costs me 2/3rds of what I'd pay other carriers, I'll put up with 2/3rds of the service.
    That's fair. You can take my $40 line access fee on AT&T unlimited and pull it from my cold, dead hands.

    90%+ of my voice usage is to other members of my family, who are either on my T-Mo plan or on a landline, so I never even knew until this thread that there was a carrier interoperability issue with this. I just assumed if both sides had VoLTE it would sound decent.

    Yeah, most people I call are Verizon or AT&T, but in the blue moon where I have to call a T-Mobile customer, I would prefer to use FaceTime audio or something else. It's very jarring. Haven't talked to anyone with Sprint in ages now. I try to keep that negativity out of my life...

Come on now...

    Keep in mind that implementing this requires cooperation on both ends. AT&T and Verizon may not want to work with T-Mobile on this, as it'd make T-Mobile just a little more competitive.

    Exactly right. There is no incentive for AT&T or Verizon to have a compatible standard. It's the great duopoly at work again.

    That's ok since T-Mobile is about to cream the duopoly after the sprint deal. They will have the best spectrum portfolio and will have the resources to build out like never before.

    AT&T, Verizon, and T-Mobile all use AMR-WB 12.65 for HD Voice. That’s a pretty bold claim to make that they “don’t have a compatible standard” and that they’re somehow bullying T-Mobile out of HD Voice compatibility, seeing as Sprint, AT&T and Verizon have complete HD interconnect. Only one doesn’t.

    I do not think it is an AT&T or Verizon wireless issue, I would say it is either due to incompetence on T Mobile USA's end or it is not a high priority item for T Mobile USA to work on at this time considering they are planning to merge Sprint into their internal systems. Not to mention it is in AT&T and Verizon's interests for their HD Voice to work with all wireless carriers since that effects their customers experience when HD Voice calling does not work.

    HD Voice calling does not work when calling my sister who uses Metro PCS a T Mobile owned MVNO. I am using Spectrum Mobile a Verizon MVNO.

    I call my sister on ATT all the time. Our calls are good. We both use iPhone 11 Pro’s.

    I think geeks like us tend-to-project what we think matters most to everyone but we’re often jaded.

    Believe me when I say that things like HD Voice, Intel vs. Qualcomm and mmWave vs. low-band NR are not things the average user is asking for when buying new service or upgrading to a new phone.

    Just my overly developed / advanced opinion. 🤪

    Verizon supports EVS 13.2kHz as well.

    Agreed. Though I did notice how crummy Verizon CDMA (non-VoLTE) calls sound vs. T-Mo, since I was using Xfinity Mobile to park my old landline number back when Xfinity was "free."

    I think most of us over 40 remember when phone calls sounded relative crummy, so most modern-day wireless calls meet or exceed our expectations anyway. Those of us under 40 text more than call, so (as Friends' Joey Tribbiani would say), it's a "moo" point.*

    I want to know what the hell is taking T-Mobile so long with getting interconnected with these other carriers. If T-Mobile had any interest in the well being of their customers and society as a whole they would act on this immediately.

    AT&T also enabled the EVS codec on their network over a month ago.

    Didn’t know that. Is it cross carrier or AT&T-AT&T only?
