How on earth is this a "vulnerability"? It needed adb shell access.
"Google's implementation of the security patch is strange, clearly targeting the Pixel IMS rather than fixing the shell's ability to modify carrier configurations. I'm actually worried that the ongoing backlash will ultimately lead Google to remove the MODIFY_PHONE_STATE permission from the shell to properly fix this issue"
Yeah, what happens when you call 911 in an environment with no 3G/2G and your carrier doesn't like your VoLTE? Is there a public safety issue embedded in all this?

VoLTE is on another layer than the one radio spectrum laws apply to. VoLTE is basically SIP with a special handshake that uses the SIM card instead of the usual username/password. It does not affect radio in any way.
I am aware, but the cell network itself is considered critical infrastructure as well, and operators are custodians of the radio spectrum. So devices that don't respect operator settings are considered problematic. Now, do operators abuse this power to enforce commercial interests? Absolutely. This may well be a case of that. But the general principle that devices that operate on the radio spectrum and in cell networ…
which is never going to happen, because lobbying has overtaken the democratic process, and legislations no longer seem to be about protecting the consumer.

I think it depends; speculating but probably volte is a very complicated spec with many optional enhancements ( think ssl with cipher types ) So carrier can choose to whitelist/blacklist phones depending on extensions available
> whitelist/blacklist phones depending on extensions available That would be, I believe, fine. Those are capabilities-based restrictions. From my point of view, the issue would be if the same phone worked with the same technology over the same mobile network when connected via a carrier A but the same phone on the same network refused to work with the same technology when connected via a carrier B.
But thats the whole point of carrier profiles ( If I didn't understand wrong. )
Eventually it is the carrier who decides what you can do. ( this can also may be related to deals they made with manufacturers )
I think in this case, it is just missing carrier profile. ( which is like a config file )
One workaround is to just do pure VOIP. Then you can get a data only plan. Gotta watch out for 911 access though. Yeah, what happens when you call 911 in an environment with no 3G/2G and your carrier doesn't like your VoLTE? Is there a public safety issue embedded in all this?

Why is having so many bands a bad thing? Demand for data is so much higher now you need (ideally) hundreds of MHz of spectrum in dense areas. You need some way to partition that up as you can't just have one huge static block of spectrum per auction. The issue with LTE isn't bands, it's the crappy way they have done VoLTE and also seemingly learnt nothing for VoNR. They should have done something like GET volte.reser…
> Why is having so many bands a bad thing? Demand for data is so much higher now you need (ideally) hundreds of MHz of spectrum in dense areas. You need some way to partition that up as you can't just have one huge static block of spectrum per auction. Because different countries use different sets of bands. That was true for GSM too, but quad band phones were reasonably available. Many phones were at least tri band,…

Pretty much, but the govt didn't do any blocking directly. They just told the carriers, "Hey, you must not allow people to use devices on your networks that are unable to make emergency calls, or we'll apply serious penalties." The carriers then responded, "I notice that there is no requirement that we allow any device that can make emergency calls. So we will only allow devices we also sell (and maybe a few other mo…
A phone company cannot test every phone in the world to block or whitelist it.
I do not see a rational reason why a mobile carrier should have any say in which connectivity technology is enabled for use with its mobile network on a particular phone model. It should work based on standards, mobile carrier's capabilities and phone's capabilities. If a phone supports capability X, such as VoLTE, then it should just work with all mobile carriers that support that capability. No conditions. As an im…

So why not actually perfect the spec and cut those uncertainties and costs...? idk.
