Though we have now had telephones with eSIM assist for years now, the expertise has not caught up sufficient to interchange conventional SIM playing cards. One key hurdle with eSIMs is in the best way it helps twin SIMs. Whilst you can arrange a number of SIM profiles in an eSIM, solely a kind of profiles could be energetic at a time. In response to a brand new report from Esper, nonetheless, Google is working to enhance eSIM assist on Android 13.

Android 13 to A number of Enabled Profiles (MEP) for eSIM

As Esper’s Mishaal Rahman studies, Google has applied what it calls A number of Enabled Profiles (MEP) on Android 13. Patented again in 2020, the expertise permits a single eSIM component to hook up with two totally different carriers on the similar time. This manner, the OEM doesn’t have so as to add two eSIM parts (which takes up area) or use a mixture of eSIM and bodily nano-SIM card slot to supply twin SIM performance.

One of the best a part of MEP is that it’s software-based, and therefore, backward appropriate with current telephones out there. The method includes utilizing a number of logical interfaces multiplexed on a single bodily interface. The report mentions that Google has been testing MEP assist on Pixel {hardware} and has added new APIs to handle eSIM profiles in Android 13.

“Google is proposing the creation of logical interfaces which are multiplexed on a single bodily interface. Every logical interface can then present an unbiased communication channel between a SIM profile and a modem, so there’d solely have to be a single precise bodily connection to the modem. No rewiring is required, so current units with a single eSIM chip wired to a modem can theoretically assist MEP,” explains Rahman.

It’s additionally price noting that the tactic in Google’s patent is platform agnostic. Therefore, we may additionally see it in motion on different platforms sooner or later. That’s if the corporate has plans to make it accessible to different firms via a license. Talking of different platforms, the iPhone 13 sequence helps two eSIMs on the similar time. Nevertheless, it stays unclear how the corporate has applied it.

Both means, we’ll hopefully have extra particulars on multi eSIM assist when Google formally launches Android 13 at Google I/O 2022 later this 12 months. So, do you assume MEP may improve eSIM adoption within the smartphone business? Share your ideas with us within the feedback.
