Android13 new function expansion, apply for a single embedded chip multi-eSIM patent

 According to foreign media reports, Google may launch eSIM in Android 13 to promote the popularity of this technology. According to the code for Android 13, it contains a patent filed by Google in 2020 that allows the use of multiple SIM profiles on a single embedded chip.

From the patent description, it is achieved by splitting the single physical data bus between the modem and the eSIM chip into multiple logical interfaces that are multiplexed on a single physical interface. It sounds a bit like modern CPUs split physical CPU cores into logical CPU cores to perform more tasks at the same time.

Unlike a physical SIM card, which requires a slot, an eSIM requires only a small component on the motherboard, which leaves more room for the phone to accommodate a larger battery, camera hardware or other components. However, not many phones have completely ditched the physical SIM slot right now.
