A story of on/off switches, invisible cloaks, and unbreakable rules
Every profile on your eSIM chip is in one of two states: Enabled ๐ข (active, phone uses it, only ONE at a time) or Disabled ๐ด (installed and ready, but sleeping). Switching is instant: no download needed! The disabled ones are just waiting for their turn.
Through your phone's eSIM settings, you can turn on any sleeping profile, turn off without deleting, delete permanently, rename them ("๐ Home," "โ๏ธ Travel Japan"), list everything installed, or do a factory reset to wipe everything back to fresh-from-factory condition.
Some profiles come with special rules that even you can't break! "Can't turn off" keeps company profiles active. "Can't delete" makes profiles permanent. "Auto-delete" self-destructs when disabled: perfect for one-time travel plans. The chip simply says "nope!" if you try to break a rule. No way around it!
Your chip might have profiles you can't see! These are called Provisioning Profiles: special keys used only for initial setup. The Assistant app hides them because they're not for everyday use. They're like the builder's keys construction workers use before handing you the front door key!
Even though your phone shows profiles as simple on/off switches, what happens inside the chip is incredibly complex. When you switch, the chip terminates all connections, closes every open channel, wipes cached data, and signals the phone's radio to reset: all in a fraction of a second!
Even though your phone shows profiles as simple on/off switches, the chip actually performs a complex multi-step dance every time you tap: terminating connections, closing channels, wiping caches, and resetting the radio. All in a fraction of a second, so you never notice!
