iPhone Duo only supports eSIM and was dismissed. Blogger: You have to delete your domestic number when going abroad.

Abstract:

The iPhone Air launched by Apple last year only supports eSIM, while the iPhone 17 series of the same period retains a physical card slot. This year, Apple’s first foldable screen iPhone Duo also uses a pure eSIM design, and related topics have once again aroused heated discussions. eSIM is a technology that integrates the functions of a physical SIM card into a mobile phone chip. Users do not need to insert or replace physical SIM cards, and can handle services such as network access, card replacement, card replenishment, shutdown or resumption, number cancellation and number portability. From a technical perspective, eSIM makes the internal space of the mobile phone more efficient and reduces the need for card slot openings.

A blogger posted a reminder that when you spend nearly 20,000 yuan to buy an iPhone Duo, you will find that this phone does not have a physical SIM card slot. The National Bank version can store up to 2 eSIM numbers, and you need to go to an offline business hall to apply for a card.

If business people use it abroad, they must delete a domestic eSIM number before writing it to the eSIM of the destination.

Some netizens reminded that if the iPhone Duo is returned to the factory for repair, the user may need to apply for a replacement physical card when using the spare machine, and then go to the business office to write the eSIM after the iPhone Duo repair is completed. This time, the extra time cost cannot be ignored.

Currently, for people who frequently travel to other places and change phones frequently, a pure eSIM solution will cause a lot of trouble. Although domestic mobile phones also support eSIM, they all retain the option of physical SIM card slots, allowing users to flexibly choose according to their own needs. This approach of taking into account both old and new solutions is obviously more in line with most people’s usage habits at this stage.
