A story of postcards, error levels, and the magical undo button
Whenever something important happens on the chip, it creates a notification: like a little postcard. "Profile Enabled!", "Profile Deleted!", or "Oops, something went wrong!" These postcards travel from the chip through the translator to the control centre and profile factory.
Sending messages uses precious battery on tiny sensors. So the system has a clever trick: bundling. Instead of sending notifications one at a time, the translator waits and sends them all together: like putting multiple postcards in one envelope. One transmission, many messages!
Errors come in three flavours: Level 1: the translator spots a problem before it reaches the chip. Level 2: the chip rejects the whole package (bad signature, low counter). Level 3: the package was fine, but one specific command inside failed. And if there's an emergency call? Everything gets blocked: saving lives comes first!
What if the translator executes a command but loses connection before reporting back? Nobody knows what happened! The fix: Profile Rollback: the translator tells the chip "oops, undo that last thing." The chip reverts to its previous state: like pressing Ctrl+Z for your SIM profiles!
When you make an emergency call on an eSIM device, the chip blocks every single management operation until you hang up: just to make absolutely sure nothing interrupts your call for help. The system returns an error meaning "busy saving lives, try later!"
