Most likely, the 6.1-inch iPhone supporting dual SIM will only be sold in China.
The latest iOS 12 has revealed that Apple will release the first iPhone that can use two SIMs.
According to the Economic Daily News , the 6.1 inch iPhone version of the LCD monitor is the only device in the iPhone 3GS 2018 series that supports this feature. Moreover, users will be difficult to access products because they are likely to be sold in the Chinese market.
