In plain English
It is the card's own serial number, used to tell one individual card apart from another in a mobile telecommunications system. Because it is unique, it identifies that specific SIM or similar integrated circuit card rather than just a general type of card.
In context
In activation details, ICCID labels the unique serial number that identifies the individual SIM or eSIM profile being referred to.
- Situation
- Porting numbers, activating SIM or eSIM, replacing devices, and changing account details
- What it communicates
- labels the SIM or eSIM profile identifier in activation details
Meaning limits
By itself, the term does not indicate who the card belongs to or any details beyond that card's unique identification.
Examples
“Although the two SIM cards came in the same package, each had a different ICCID.”
“For the activation request, the technician entered the ICCID from the replacement SIM.”
