A form of this has existed for a while but never caught on for fairly understandable reasons.

Quite a few years ago (2005?) a family member purchased a Samsung-branded dumbphone on a contract. (Monochrome LCD (something like 128x64?), polyphonic ringtones, 3 fixed games, a (really slow, GSM data) WAP browser; that was it. Model SGH-something, I vaguely recall.)

It had no SIM card slot. It was locked to the network (Orange - in Australia FWIW) via software. In order to unlock it we had to call up the telco and go through some process, which we decided not to do in the end (whatever it was, I don't recall), since the phone had less capabilities than the Nokias that flood India and similar places, so we concluded there was no point selling it by the time we dug it out one day and tried to figure out what to do with it. (It's still buried in a box somewhere IIRC.)

I think this is why SIM-less phones are reasonably rare - it's really, really hard to de-contract them, unlock them and put them into sellable (or whatever) condition. Then once you've done that the recipient has to go through some equally arcane process to get the thing linked to a plan/contract too. And considering the ability to pass a phone on is a fairly major selling point - phones aren't solely purchased [preconfigured] on plans, then disposed - I think this was explored somewhat by the industry but ultimately left alone.

Some of the other things I've found in this thread are really interesting, although I wonder how difficult it is to "unconfigure" such a device to sell or pass it on.

It was probably just a CDMA phone - they don't have SIM cards are were actually quite common a while ago.
CDMA phone are worse. It is a way for manufacture of mobile phone to keep you tied to one cellular company.

I always go for GSM supported phones.

Aha! That's what it was, you're right.
