Google plus continues to build Android 13 for the release of the final version next fall. Apart from the news that we have been observing in the test editions published to date, another attractive news has arrived for those who want to use multiple phones in exactly the same terminal: the intelligent mobile system will endure multiple specifics in just one eSIM.

A while ago physical and removable SIM cards should have lived to a better life in pursuit of eSIM, the new generation virtual SIMs that are inside in the form of a chip inserted from the factory in the platform plates and that, like standard SIMs, allow us to connect to the Internet and make calls and messages, but with a much higher potential and virtues in design.

Beyond the hardware, with an eSIM you don't have to go to a store to get your SIM (or wait for it to arrive in the mail) when you switch carriers. Portability is much faster, as is the hiring of auxiliary services. In addition to this, the data of the virtual SIM is saved in the cloud, facilitating its use on multiple devices by simply entering the user's credentials. To conclude, indicate that each and every one of these virtues can be extended from smartphones to PCs, wearables or the Internet of Things.

But there's still quite a way to go before it is universally coincident with each and every one of the operators. If you need to use 2 different smartphone numbers in a single device, the solution until now was the dual SIM. One of its virtues is that you have the possibility of using 2 smart mobile service providers simultaneously if the phone is not denied on a specific network and with this you can find greater smart mobile coverage. We were able to find another example of employment in certain markets, especially emerging ones, to divide voice and data rates. It's useful, but annoying.

Android 13 with MEP support

Until now most of teSIM capable phones are incompatible with dual SIM utility unless the OEM included 2 chips eSIM in the phone. However, Google plus has a solution to this problem and everything indicates that it will carry it out in Android 13. The Google plus solution will arrive with the appearance of support for multiple concretes enabled (MEP), a procedure to activate multiple concrete SIMs in just one eSIM.

Google plus got a patent for this technology in the time of 2020 and we saw references to it on AOSP and on the Android developer site. With support for MEP, a single eSIM element can connect to 2 different operators at the same time, ruling out the need to have 2 eSIMs or one eSIM much more a nano SIM card to have dual SIM occupation. This cuts costs and frees up valuable space for other hardware, which is especially essential for items like smartphones, tablets, and foldables.

How does it go?

Each SIM profile that a user downloads and also installs on an eSIM chip is associated with a “dedicated communication work platform”. This communication work platform gives a “communication channel without dependency” between the SIM profile installed on an eSIM chip and a modem, and is generally a physical working platform that connects the 2 via cables/buses.

A physical work platform is required to connect an eSIM chip and a modem, but since that work platform only accepts a single communication channel, 2 physical interfaces would be required to let 2 specific SIMs stored in an eSIM chip communicate for each other. work with a single modem in Dual SIM.

To circumvent this, Google plus offers the creation of logical interfaces that are multiplexed on only one physical work platform. Each logical workstation can provide a non-dependent communication channel between a SIM profile and a modem, requiring only a single actual physical connection to the modem. And it doesn't need to be rewired, so gadgets that already have a single eSIM chip connected to a modem could theoretically accept MEP. From the view of the modem, there is no difference between a logical and a physical work platform, which leaves compatibility with previous editions.

And in addition to this, since the Google plus approach is generic, it is also without dependency on the interface. In truth, Android 13 may not be the only matching OS with this technology, as Google plus explicitly targets other OSes like iOS, macOS, and Windows in its patent.

It's not clear if Google plus plans to make this technology available to everyone for free or through some patent licensing scheme. Google plus has been testing MEP compatibility on unspecified Pixel hardware and has incorporated the new APIs into its app that manages eSIM specifications, so we will surely at least see this technology on some Pixel-capable smartphone. The initiative is the one outlined, supporting multiple concretes in just one eSIM.
