A story of how consumer phones and IoT robots joined forces under one mighty spec
For years, the eSIM ecosystem was split in two: SGP.22 for consumer phones (where you scan QR codes) and SGP.02 for IoT machines (cars, sensors, factory robots). Same chip: two completely different rulebooks. Companies had to build everything twice!
Having two separate specs meant double the work for everyone: chip makers, carriers, phone manufacturers. Worse, each spec missed features the other had. The GSMA decided: what if we combined the best of both worlds into one unified rulebook?
SGP.22 v3.x is the grand unification! Whether you're a smartphone, a smartwatch, a car, or a factory sensor: you now all follow the same rulebook. The best features from both worlds are merged: push notifications from IoT, multiple profiles from consumer, and brand-new capabilities neither had before.
v3.x introduces six big innovations: Multiple Enabled Profiles (MEP) so you can be on two networks at once, Push Service for instant notifications, Feature Support handshakes, Device Change to move keys between phones, Chip Updates to keep your vault modern, and Interoperability rules so old and new can coexist peacefully.
For nearly a decade, two parallel eSIM worlds existed side by side. In 2024, the GSMA decided: let's bring them together. SGP.22 v3.x absorbs the best of SGP.02 and adds brand-new features, creating a single, future-proof standard that works for phones, cars, watches, sensors: and whatever comes next!
SGP.22 v3.x isn't just an update: it's the biggest eSIM standard merger ever. By absorbing SGP.02's best ideas (remote management, push notifications) and adding new ones (MEP, device change), it creates one rulebook for every connected device on the planet. That's billions of devices speaking the same language!
