April 2 news, according to Esper reported that Google's Android 13 system will fully promote the development of eSIM technology, or will support a chip to natively open multiple eSIM virtual mobile phone cards.

Compared with physical mobile phone cards, the advantage of eSIM virtual mobile phone cards is that they are easy to handle and do not need to insert physical mobile phone cards. However, this technology is not popular in China, because mobile phones have physical SIM card slots, not much use to get eSIM, the real suitable eSIM device is a smart watch.
Smartwatches are smaller, and if a physical SIM card slot is built in, there's not much room left for batteries and other accessories. However, there are not many smart watches that support eSIM in China, because in the eyes of the vast majority of people, smart watches are just a large bracelet, which is an accessory device to the mobile phone, rather than an independent smart device.
In the mobile phone industry, the rise of eSIM technology is a good thing, although the size of the mobile phone is relatively large, but the interior is also inexhaustible. If the physical SIM card slot is removed, then some space is left for accessories such as batteries, cooling components, and sensors with a larger bottom.
The problem is that SIM cards have a huge advantage, that is, they are easy to manage. Now to apply for mobile phone cards, operators require us to register with real names, and mobile phone cards are handled more, and they may be restricted. Before Xiao Lei bought a mobile phone card as a backup, usually only used for the backup machine to access the Internet, but because he did not make a call, it did not take long to be banned by the operator, asking me to go to the store to unseal.
Operator requirements are so strict when it comes to physical cards, not to mention the inconvenient eSIM for management. In recent years, global telecommunications fraud has been rampant, and operators and relevant departments are trying their best to deal with it. Therefore, even if the practicality of the eSIM card is improved, under the requirements of operators and relevant departments, the equipment of domestic mobile phone manufacturers will most likely not give up the physical SIM.
Two years ago, some mobile phone manufacturers launched a concept machine without a hole design, and this kind of holeless design may become one of the directions of future mobile phone development, but there are too many problems at this stage. Technological progress is always a good thing, and its future cannot be denied because it has no practical value now.
According to Google's usual style, the Android 13 series should be released this fall, and mainstream Android flagships can upgrade the system at the end of the year.
