The Verizon CDMA shutdown is for the ESN/MEID non-SIM version and Verizon uses it for both their 2G and 3G network.
Iirc, only devices with 4G LTE have SIM card slots when it comes to Verizon.
For me at least, voice calls on Verizon are always on VoLTE now. It’s easy to tell because on Verizon CDMA, you lose data when you make calls and that’s not happening anymore with LTE (likely because they’re using LTE data for the calls).
After the CDMA shutoff, all Verizon mobiles will need to have VoLTE in order to make calls. Phones such as the iPhone 5 and 5s which have LTE but no VoLTE support will not work for calls on Verizon. I tried activating a Verizon-branded iPhone 5s (whitelisted MEID/IME) on prepaid around Dec 19/Jan 20 and Verizon wouldn’t let me.
GSM 3G on AT&T and T-Mobile continue to operate as normal for now.
