the radio cannot be software defined (and user modifiable) for type acceptance and regulatory reasons
In what country? The FCC certainly allows SDR to be certified. "User modifiable" is sufficiently broad as to be nearly meaningless.

This is bizarre. After you pointed out my error, I went to Wikipedia to verify before saying anything more. I was wrong originally; you, me, and your link all know it. But Wikipedia says it was AT&T that first carried the iPhone [0]. I assume it's because AT&T bought Cingular, but it feels off not noting that it was branded under Cingular instead of the separate (at the time) AT&T. It's an eerie feeling finding error…
It is shocking to me that anyone would consider Wikipedia as an irrefutable source of truth.
If I'm at a bar and want to settle something lighthearted between friends, Wikipedia is the source of choice. If it's worth delving deeper, we'll go deeper, but for a quick answer I trust Wikipedia more than saying "Hey Google, which network was the first iPhone exclusive to?"
Perhaps irrefutable is too strong a word, but if I'm looking for an answer (instead of researching a topic) and want a quick, single source, Wikipedia is my go-to.

Here's the actual text on restrictions for SDR: https://www.law.cornell.edu/cfr/text/47/2.944
The FCC defines SDR here extremely broadly, any radio which "frequency range, modulation type or maximum output power (either radiated or conducted)" can be changed.
This describes a substantial portion of radios - including many if not most WiFi access points. They are legal and many US companies design, manufacture, and/or sell these types of radios (I work for one of them).

Wow this is crazy. In India, operators have no incentive in what handset their customer uses so they cannot interfer with user's choices. Besides, they can't disable 3G/2G because of the sheer amount of people who still use these networks from villages.
> Besides, they can't disable 3G/2G Jio has no 2G/3G and they have one of the widest ranging networks encompassing most remote villages. It has never been a problem. I suspect Airtel and Vodafone will turn off their 2g/3g soon.
>Jio has no 2G/3G and they have one of the widest ranging networks encompassing most remote villages.
that's coz they have a "roaming agreement" with BSNL to use the latter's 2G network

Ahhh... TIL. I had no idea.

The loss of 3G is going to be an unmitigated disaster it seems. Might even be appropriate for the FCC to step in and force them to keep it up. A lesser loss is that 3G often works in a big crowd where LTE is overloaded. Maybe that'll at least change to 5G vs LTE over time.
It’s insane to keep a massive portion of spectrum on this old technology to support a very small amount of people with outdated hardware.

Absolutely they are legal to sell, but you have to go through type acceptance under part 15, and then you need to make it so the user cannot modify them.
“ The rules require any manufacturer certifying a device under the new process to take steps to prevent “unauthorized” changes to the software on the device that might alter its radio frequency and power parameters in a way that takes it out of compliance with the regulations known as FCC Part 15 regulations.”
Test equipment is exempt because it is not licensed as an intentional emitter under part 15.

#148A few weeks ago I moved my sim from a broken LG V20 to a Oneplus 3t and att suspended my account. I wasn't sent a message or any kind of notification. My sim just stopped working. I had to call att support for 30+ minutes to find out that it was because the 3t doesn't support volte and get my account reactivated. The way att has been handling this transition has been really shitty. VOLTE is a banned subject on the li…
Not quite clear from your comment, it stopped working even when you switched it back to your old phone? Otherwise, it just sounds like your phone didn't work because it was incompatible, not because your account was banned.
My account was completely disabled. I tried two other phones that are compatible with att volte and they only worked after talking to att support.
