In the new Apple smartphones found support for working with two SIM cards. About this on his YouTube Channel stated blogger Hugh Jeffreys.
At the moment, Apple smartphones with support for the second physical SIM card are made only for the China Market. To add the second SIM card to the classic iPhone, Blogger acquired on one of the shopping tray for the Apple phone released for the Chinese market. In order for the secret function of the smartphone to start working, the author had to disassemble his iPhone 12.
Removing your own machine, Jeffrex removed the ordinary tray for one SIM card and replaced it to a similar spare part from the iPhone donor from China, intended for two SIM cards. After the enthusiast attached the item to the place and collected the phone, two SIM cards appeared on the device.
Hugh Jeffreys explained that all Apple phones starting with iPhone XR and iPhone XS can work with two SIM cards. However, in devices released for different from the Chinese markets, the function of the second SIM card executes ESIM. In the case of installation in smartphones for American or European markets, the ESIM support is stopped, as the smartphone automatically assigns it IMEI (international mobile equipment identifier) by the second physical sim card.
In conclusion, Jeffreys said that for the upgrade of the smartphone, a tray for two SIM cards is required, which can be purchased about 500 rubles, and screwdrivers for disassembling the device. The author clarified that in the event of the installation of the new equipment, the official warranty on the iPhone stops.
