[Q] 816 dual vs single sim

I am interested in 816 dual sim but I found that it has a different processor then the single sim version (single sim is Msm8928 and dual sim is msm8228) so will this differ in rom development (CM11) i.e. we will need a separate device tree and such details?

Question [Q] can I flash it with the global ROM to activate dual SIM

Hi Guy,
I have a NA OnePlus 9 pro, can I flash it with the global ROM to activate dual SIM and if so how would I do it?
I am a newbie and this is my first dabble into android and I need dual sim for work.

First off, your NA Oneplus 9 Pro is the global ROM(unless you have a T-Mobile version). Second, Global ROM does not support dual SIM yet.

Also, check your sim card tray. On NA version, the 2nd tray has a black bar on it preventing you from even inserting a 2nd sim.

i think even you buy a dual sim tray for oneplus 9 pro, the dual sim is still locked in the software side.
