So let me see if in understand you correctly. If I am using dual sims, the only way for to use the iPhone 12 and obtain 5G is to move to Mainland China!


Otherwise 5G doesn’t work anywhere else in the world using dual sims?


So there’s no difference in the IPhone 11 and the iPhone 12 since the main point is using 5G. It’s just another way of Obtaining money to apples income.


so why not buy a Samsung, Oppo, Huwai or other phone since they all support 5G in dual sim mode?


afterall I didn’t but the Phone for the camera, I bought it for the phone!


Am i incorrect about any of my statements? Please advise
