This is one of those "but actually" things that always happens (and why I can't give a straight answer and why I should have hedged that statement as well). The question was about the US and Apple and I responded about the US and Apple, but I should have know I'd get a "but actually" if I didn't hedge everything.
I don't know what country/network you're talking about, but it looks like Uzbekistan might be the only country that's valid for.

Beeline Armenia doesn't have a shutdown date, they also have GSM/UMTS/LTE service and their CDMA network is at 450MHz which the iPhone has never supported. MPT has an LTE service. That leaves Perfectum Mobile in Uzbekistan which looks like it's still heavy in CDMA. Uzmobile also seems to run CDMA at 450MHz, but again the iPhone never supported that. Going through Perfectum's website and looking at their suitable models feels like growing Verizon and Sprint's website from years past.
Yea, I should have hedged further and said "in the US and for Apple's purposes." Really though, I can only find Uzbekistan as an exception. And I could see Uzbekistan lingering on CDMA. Are there more?
I'm not even saying that old tech doesn't linger. Part of it is that CDMA wasn't popular in most of the world. GSM support will stick around longer because it was so popular. Most places that had CDMA networks have replaced them. CDMA kinda became a dead-end technology as Qualcomm's UMB evolution didn't happen - once Verizon chose LTE, there wasn't much of a point.
Honestly, it would have been cool if you'd added information about countries and networks where CDMA might stick around. I'd love interesting information - I literally went around looking for the information not included in your comment. Without that information, it just feels like "I know you were talking about Apple and the US, but actually..."
- toast0 5y agoI'm having trouble finding things with searching tonight. But I think I know where to look to get the pointers I need... I'll see if I can dig up some examples tomorrow. Although, maybe I'll find that everyone has moved to LTE. I was dealing with phone numbers for several years and there had been several networks which were CDMA for home phones only in otherwise GSM nations that started doing mobile phones. I suspect I can find some of the ones I managed to get added to libphonenumber when I was contributing to it. But, I don't know the frequencies, maybe they were at 450 and not iPhone accessible.
- toast0 5y agoWell, I still can't find the references I'm looking for. So I'll accept that CDMA will be dead, and we can both be surprised if it survives a little bit longer.
