Just started happening today but I noticed I couldn't make/receive calls even though I could send/receive SMS and get a data connection. Pixel 5 on Verizon.

After turning on Advanced Calling the calls work no problem.

I've never needed to have this on to get phone calls before.

Don't think there were any Graphene updates between it working last and now. Carrier issue?

Also yes I know Pixel 5 is going out of support.

    According to Internet rumor, "Advanced Calling" is another name for VoLTE:

    I believe Verizon has required VoLTE network-wide since the end of 2022.

    Regardless, if I disable Advanced Calling on a 6a on Verizon, I instantly can't make calls.

        de0u If that's the case its interesting that I was able to make calls with it disabled well beyond 2022. Do you know of any privacy implications of using VoLTE? It seems like this feature routes calls over cell data instead of actually using the traditional cell network.

            I am not in a position to dispute the configuration of your device. However, here are some claims:

            VoLTE does indeed route calls over cellular data instead of using older voice-specific cellular protocols. Based on everything I've read online, and my own personal experience as a Verizon customer, Verizon has completely turned off the older voice-specific cellular protocols. At this point, on Verizon's network, VoLTE is not something that one can choose to use or not use, if one wishes to make voice calls carried by that network.

            In general, cellular voice calls are not high-privacy items. I don't believe they are end-to-end encrypted, and I believe the non-e2e encryption has some issues (source).

                  de0u Strange. Either CDMA was somehow still working in my area or my phone previously ignored the Advanced Calling setting.

                  Yeah I guess if all carriers are shutting down 3G voice then the privacy implications don't really matter. Then my choices becomes VoLTE or the new VoNR on 5G.

                  I know 5G is probably worse for privacy due to the extreme geolocation precision. Are there any other privacy concerns of 5G I should know about before switching?

                      I think that's accurate.

                      I have heard that meme a lot, but personally I'm not aware of a strong analysis. For example, I don't think mmWave 5G is all that prevalent.

                      I think 5G enthusiasts (e.g., people who wanted government subsidies for rollout, people who wanted everybody to hurry up and buy a 5G-capable handset) went through a period of claiming that 5G would be so! much! better! in every way, including that if you lost your phone your carrier could tell you which corner of which shelf in your garage you had left it on (woohoo!). And it's true that mmWave cell sites would need to be more dense if they were widely deployed, which would tend to improve localization precision.

                      But personally I haven't seen anything indicating that 5G in practice means your carrier can tell which bathroom stall you're in. And meanwhile, personally, I have set my phone to prefer LTE because I think it improves battery life and network stability.
