S9 Exynos CDMA - Samsung Galaxy S9+ Questions & Answers

If it has CDMA bands and it's rootable, why hasn't a method for enabling the CDMA bands been found yet?
"I will also add that in the past the dual-sourcing made sense due to technical limitations. CDMA compatibility for Verizon and Sprint in the US and China Telecom in China made for compelling arguments for using Snapdragon variants in those markets. However since then Samsung has introduced discrete modems and Exynos SoCs with CDMA compatibility. Indeed the Exynos 9810’s new modem supports CDMA. Samsung’s licensing dispute with Qualcomm and their recent reconciliation points out to issues beyond “simple” technical matters. The fact that the Snapdragon 845 is produced by Samsung is also a factor at play. The foundry business used to be under the same corporate roof as the SoC business making Exynos chips, however last summer Samsung has spun off the manufacturing part into a separate business unit. What this means for the future of dual-sourcing Snapdragon and Exynos SoCs remains uncertain, but for now the Galaxy S9 still continues the tradition, for better or worse."

Sure you're not confusing CDMA with WCDMA? They aren't the same thing, and the Exynos variants don't have a CDMA radio (hence why the Snapdragon version is the one sold in the US for Sprint & Verizon).

Interesting..... Now of course there's the secondary issue in the US at least, in that Sprint nor Verizon would still have to activate the device on their network; something they tend not to do for most devices they don't sell. I also don't believe CDMA devices use a SIM card nor the IMEI number, so you'd have to generate an ESN or MEID number manually (something that could probably be considered as illegal as changing the IMEI in many areas).
Bottom line, there's more to CDMA than just activating the radio or ensuring the proper bands are supported - at least from my understanding of the technology. Of course, I may be mistaken here just like I was about the Exynos 9810 theoretically supporting CDMA, but I still stand by my belief that it's more complicated than how we could enable Band 4 LTE on the Nexus 4 back in the day.

Verizon wireless has BYOD, so I think that rectifies one issue. Well, it's a bummer I can't connect to VZW on an exynos S9. How do I go about making it work?

On my unrooted S9+ UAE Exynos, I got into the Mobile Network Settings. It's axiomatic that there's an option for LTE/CDMA; however, I cannot make it stick. It may be a futile option, but I don't know . Can someone test this?
