Google Android 13 was exposed to apply for a single embedded chip with multiple eSIM patents. Unlike a physical SIM card that needs a slot, eSIM only needs a small component on the motherboard, which leaves more space for the mobile phone.

Google Android 13 was exposed to apply for multiple eSIM patents for a single embedded chip 1. According to Speer, Google 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 the physical mobile phone card, the advantage of eSIM virtual mobile phone card is that it is convenient to handle and does not need to insert a physical mobile phone card. However, this technology is not popular in China, because mobile phones have physical SIM card slots, and it is of little use to get eSIM. The device that is really suitable for eSIM is a smart watch.
Smart watches are small in size. If the physical SIM card slot is built in, there is not much room for batteries and other accessories. However, there are not many smart watches supporting eSIM in China, because in the eyes of most people, smart watches are just a big hand ring, an accessory device of a mobile phone, not 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, the interior is also inch by inch. If the physical SIM card slot is cancelled, a part of space can be reserved for placing accessories such as batteries, heat dissipation elements and sensors with large bottom.
The problem is that the SIM card has a huge advantage, that is, it is easy to manage. Now, for mobile phone cards, operators require us to register our real names. There are many mobile phone cards, which may be restricted.

Operators are so strict with physical cards, not to mention eSIM, which is inconvenient to manage. This can't blame the operators. In recent years, global telecom fraud is rampant, and operators and relevant departments are trying their best to control it. Therefore, even if the practicality of the eSIM card is improved, the equipment of domestic mobile phone manufacturers will not give up the physical SIM at the request of operators and relevant departments.
Two years ago, a mobile phone manufacturer introduced a concept machine with non-porous design. This non-porous design may become one of the development directions of mobile phones in the future, but there are too many problems at this stage. Technological progress is always a good thing, and its future cannot be denied just because it has no practical value now.
According to Google's consistent style, the Android 13 series should be released this fall, and the mainstream Android flagship can upgrade the system by the end of the year.
Google Android 13 was exposed to apply for multiple eSIM patents for a single embedded chip. Traditional mobile phones use a physical card called SIM card to connect to the cellular network. At present, the progress of the eSIM digital card being promoted is not fast, partly because Android is not well supported. According to Speer's latest report, Google may launch eSIM in Android 13 to promote the popularization of this technology.
Speer reported that the code base of Android 13 includes a patent filed by Google in 2020, which allows multiple SIM card profiles to be used on a single embedded chip.
According to the patent description, it is realized by dividing a single physical data bus between a modem and an eSIM chip into a plurality of logical interfaces, and these logical interfaces are multiplexed on a single physical interface. It sounds a bit like modern CPU splitting physical CPU cores into logical CPU cores, so as to perform more tasks at the same time.
It is understood that unlike a physical SIM card that requires a slot, eSIM only needs a small component on the motherboard, which leaves more space for the mobile phone to accommodate larger batteries, camera hardware or other components. But at present, there are not many mobile phones that completely abandon the physical SIM card slot.
Google didn't mention this feature publicly, but if it does remain in the final version of Android 13, it will be a great boost to the eSIM card.

According to the patent description, it is realized by dividing a single physical data bus between a modem and an eSIM chip into a plurality of logical interfaces, and these logical interfaces are multiplexed on a single physical interface.
It is reported that the eSIM card directly embeds the traditional SIM card into the device chip, instead of being added to the device as an independent detachable component, so users do not need to insert a physical SIM card, just like PHS in the early years.
ESIM has many advantages. Because it is no longer necessary to set up an independent SIM card slot for the equipment, the equipment designed with eSIM will have a lighter and thinner body in the future, and consumers can change operators at any time for the sake of cost and operator advantages.
In addition, this arrangement leaves more room for the mobile phone to accommodate larger batteries, camera hardware or other components.
Compared with the physical SIM card, eSIM has higher security, and it will be difficult for hackers to crack stolen mobile phones in the future.
For enterprises, they can access the enterprise network through the method of eSIM card authentication, and delete the device data remotely through the "mobile device management solution" when employees' devices are lost.
Google officials did not mention information about eSIM. If it is implemented in Android 13, it will be a great boost to the eSIM card.
