If you own an iPhone XR, iPhone 11, or iPhone 12, you may be able to perform a dual-SIM hack on it. This allows users to insert two nano-SIMS, even if they’re from different wireless carriers, into the handset and use them.
While this feature is currently only available in China, and Apple doesn’t provide the configurations anywhere else, it may be feasible (Apple currently allows the iPhone 12 to use a physical SIM card along with a second, digital eSIM card).
YouTuber Hugh Jeffreys , however, had the idea to try swapping the SIM reader and tray in a non-Chinese iPhone for one from China. Surprisingly, the hardware hack works and provides dual-SIM support for non-Chinese iPhones, as seen below.

Stay tuned for additional details as they become available.
