A story of weather sensors, sleepy devices, and fleet-sized thinking
Phones have screens to tap, SMS messages, and always-on internet. But tiny IoT robots have none of that: they're sealed in boxes, sleep for days, and there are thousands of them. So engineers built a brand new system called SGP.31 and SGP.32.
Instead of tapping a phone screen, a Remote Control Centre (called the eIM) manages everything from the cloud. One person can control thousands of devices from a single dashboard: sending commands, switching profiles, and checking status.
Each device has a little helper called the IPA (IoT Profile Assistant). It's like a translator: it takes commands from the remote control centre and passes them to the eSIM chip. The IPA doesn't make decisions: it just delivers messages, like a faithful messenger.
What if a profile switch goes wrong and the robot loses connection? The chip has a fallback profile: an automatic parachute. And if a download breaks, it can roll back like pressing "undo." Plus, the system is careful not to wear out the chip's memory: some devices need to run for 10+ years on one battery!
Everything is remote, automatic, and built for fleets of thousands. No tapping screens, no QR codes, no naming profiles: just signed commands from the cloud and devices that take care of themselves.
Some IoT devices are designed to run for 10+ years on a single battery: so the eSIM system has to be careful not to wear out the chip's memory with too many writes. Every operation is precious!
