News sources have announced the possibility of Android 13 supporting an e-SIM by connecting to two operators
In this technology, there is no need to use physical SIM cards and They are not in the phone and SIM card information is stored on a chip inside the device. Of course, eSIM also has its own difficulties that have prevented its general acceptance; The difficulties that Esper blog report, Google is trying to fix one of the most important ones in the latest version of its operating system, Android 13.
The main problem in this regard is how to support two SIM cards with eSIM chips; Because using this technology, you can only work with one subscription line at any time. According to Esper’s report, Google will grant a patent to registered and it uses a feature called multiple enabled profiles or MEP (abbreviated as multiple enabled profiles) is to enable the simultaneous use of several active SIM card profiles in one eSIM. In other words, a single eSIM module will be able to connect to two different operators and provide simultaneous user access to both of them.
The interesting thing about this method is that everything happens at the software level and several logical interfaces act as independent communication channels between the SIM card profile and the phone modem; While there is only one real physical connection between the components of this process. In fact, Google adds API classes to Android Open Source Project or AOSP code and to carrier apps. It will allow them to receive the information related to the logical and physical interfaces along with the SIM card profiles stored in them and provide services in this way.
While eSIMs currently have the ability to store multiple profiles on a single chip and support switching between them, only one profile is active at a time. can be used In other words, the only way to get dual-SIM support with existing solutions is to buy a device with multiple eSIMs, multiple physical SIMs, or a combination of an eSIM and a physical SIM.
The question that arises here is why manufacturers don’t use two eSIMs? The answer comes back to the way the phones are made, because having two eSIMs will still occupy the available space, and although the amount of space required will still be less than a physical SIM card, it makes using this method a kind of violation of intent. In fact, with MEP’s support for two active SIM cards in one eSIM module, the cost of materials needed to build the phone will be reduced for manufacturers, and at the same time, additional space will be created to add hardware or use a larger battery. However, if you use multiple eSIMs, some of this free space will be occupied again.
News and rumors indicate that the Android 13 operating system will support dual eSIMs and not only the Android open source project codes. have mentioned this technology, but the website of the developers of this operating system has also announced the possibility of the presence of eSIM in the form of MEP in Android 13. Of course, some new API examples for MEP have already been presented to developers in the second version of the Android 13 preview, and now we have to wait for its full and final implementation in the latest Google operating system.
Of course, Android 13 is not the only operating system that has the ability to support MEP and Google In his patent, he mentions iOS, macOS and Windows as other possible platforms for implementing this method. According to reports, Google has also tested MEP support on some Pixel phones and may consider licensing its patent in the future so that other operating systems can use it.
In this way, if Google’s solution is widely accepted and more operators support eSIM, we will probably see the disappearance of physical SIM cards in the future. Which, of course, will not be realized in the near future due to the existing conditions.
