google: how Google can solve the big SIM card “problem” with Android 13


google may have cracked the code to eliminate physical SIM cards for good. It looks like the tech giant will solve this problem with Android 13.
SIM cards are at the heart of every phone and allow users to receive calls, send messages and even connect to the Internet. These tiny modules are so essential to phones that manufacturers must integrate them, regardless of space constraints. Lack of space inside the devices caused the form factor to shift from full to mini, micro and eventually nano SIM.
These days, some phones are available with embedded SIM cards (eSIM). These new modules can replace traditional cards. However, there is a problem with eSIMs that can prevent them from taking over and that’s where it android 13 functionality comes into play.
The limits of an eSIM
The main problem that eSIMs face is dual SIM support. These chips are designed to work with only one service provider at a time. However, eSIMs can currently store multiple profiles on a single chip and support switching between them, but there is a catch. An eSIM can only keep one active profile at a time. So the only way to get dual SIM support with existing solutions is to buy a device with multiple eSIMs, multiple physical SIMs, or one eSIM and one physical SIM. SIM card.
Why don’t manufacturers just use two eSIMs?
Adding another eSIM slot to the already crammed interior of the device will undermine the whole point of the technology. Even though eSIMs take up less space than physical cards, having two eSIMs would still limit the available space.
How can Google solve this problem?
According to Android Police, Google’s solution will use something called multiple profiles enabled (MEP) which will allow multiple active SIM profiles on a single eSIM. This means that a single eSIM will be able to connect to two different carriers at the same time.
How should this work?
Google’s MEP method becomes more interesting because everything probably happens at the software level. Multiple logical interfaces will serve as independent communication channels between a SIM profile and the phone’s modem while maintaining a single physical connection between the components.
The company will also add API classes to the Android Open Source Project (AOSP) that will allow carrier applications to obtain information about logical and physical interfaces as well as SIM profiles stored on them. Earlier reports suggested that Google was testing it on an engineering pixel Equipment.
When should we expect the arrival of this technology?
According to reports, Google is likely to introduce this supercharged eSIM support on Android 13 as the credentials for this technology are AOSP and the Android developer website suggests its integration in the upcoming OS.
Some new MEP APIs are also present in the second and hopefully latest Android 13 Developer Preview. There will be more information about this feature as betas of the next operating system are released. The company plans to release six betas in six months starting in April
How will this feature help users?
This feature would potentially be a game-changer for people using two SIM cards on a single phone while giving smartphone makers some extra headroom. This feature can later be implemented on iOS and even Windows. However, it is important to note that Apple already allows the iPhone 13 to use two eSIMs for two or more mobile plans.
