Is the upcoming Google eSIM, future of mobile networking and communication?

Android 13’s eSIM seems to be the future of mobile networking and communications. For those who are tired of juggling SIM cards and eSIMs to switch between carriers, Google may have a solution on the way in Android 13: allowing multiple profiles on a single eSIM. Introducing the Google eSIM.

What is the new eSIM?

Google’s solution to allow multiple enabled profiles (MEP) was referenced in the Android Open Source Project and Android Developers website, which suggests it’s coming in the next big Android 13 update, according to a blog post on Thursday by Mishaal Rahman, senior technical editor for Android developer platform Esper.

While allowing multiple profiles on a single eSIM card will make it far easier for folks who want to switch between carrier networks, it also cuts hardware costs, sparing the need to make space for one or two physical SIM cards. Instead, phone-makers could use the space to expand battery size or allow a slot for expandable storage via micro SD card (a feature frequently cut to save room for a physical SIM card).

What is the accessibility of the Google eSIM?

US consumers may not widely switch between SIM profiles on their phones, but it’s handy for those switching between personal and professional lines. More importantly, the capability is a big priority for phone owners in other countries, where phone-makers market device variants with a combination of one physical SIM and an eSIM or two physical SIM cards. Phones currently rely on a physical connection between SIM and modem, requiring separate connections for multiple SIMs. Google’s MEP solution, which was granted a patent in 2020, splits a single physical interface between different digital (logic) connections. After finding evidence that Google has been trying out the MEP solution on “unspecified Pixel hardware,” Rahman predicts that this approach will debut in Android 13. But the solution isn’t specific to Android, meaning it could be applied to other operating systems, like iOS or Windows.
