Android 13 could help a number of eSIMs, even when a cellphone wasn’t constructed for it


Telephones have historically used bodily playing cards known as SIM playing cards to hook up with mobile networks, however there was sluggish progress on switching to a digital model known as eSIM. One of many causes we haven’t seen extra telephones dropping the SIM card slot totally is that Android doesn’t have nice help for a number of eSIMs, which must occur first earlier than most producers could make the swap. The upcoming Android 13 replace seems to be laying the groundwork for precisely that.

Esper experiences that the codebase for Android 13 accommodates an implementation of a patent filed by Google in 2020, which permits a number of SIM profiles for use on a single embedded chip. This works by splitting the one bodily knowledge bus between the modem and eSIM chip into a number of logical interfaces which might be multiplexed on a single bodily interface. It’s type of like how most fashionable CPUs break up bodily CPU cores into logical CPU cores, so extra duties may be carried out on the identical time.

Not like bodily SIM playing cards, which require a big slot on the aspect of a cellphone or pill, eSIM solely requires a small element on the gadget’s motherboard. That leaves more room within the cellphone for a bigger battery, digital camera {hardware}, or the rest. Nevertheless, there haven’t been many telephones that drop the bodily SIM card slot totally — partially as a result of many carriers nonetheless don’t help eSIM, and partially as a result of many units bought internationally have to have two SIMs of some sort. Two eSIMs is an possibility, which the iPhone 13 sequence presents, however that provides extra complexity.

Google hasn’t talked about this performance publicly but, but when it does keep in Android 13 for the ultimate launch, we’ll possible hear extra about it quickly. The brand new performance might result in wider eSIM help throughout telephones, so long as carriers may be satisfied.
