Android 13 New Feature Expansion

According to foreign media reports, Google may focus on eSIM in Android 13 to promote the popularization of this technology. According to the code of Android 13, its content includes a patent submitted by Google in 2020, which allows the use of multiple SIM configuration files on a single embedded chip.
From the patent description, it is achieved by splitting a single physical data bus between the modem and eSIM chip into multiple logical interfaces, which are reused on a single physical interface. It sounds a bit like modern CPUs splitting physical CPU cores into logical CPU cores to perform more tasks simultaneously.
Unlike physical SIM cards that require slots, eSIM only requires a small component on the motherboard, which leaves more space for the phone to accommodate larger batteries, camera hardware, or other components. However, there are currently not many phones that have completely abandoned their physical SIM card slots. A previous report from a statistical agency showed that Huawei's 5G mobile phone shipments in 2019 remained the world's largest, with a quantity of 6.9 million units and a market share of 36.9%. Samsung followed closely, with a shipment volume of 6.5 million units and a market share of 35.8%. vivo ranked third with a shipment volume of 2 million units and a market share of 10.7%.
