A SIM PIN adds an extra layer of security to your phone. It stops anyone else from using your SIM or eSIM to make calls or use data if they get their hands on your device.
What is the default SIM PIN?
The default PIN for all iD Mobile SIMs is 0000.
To keep your account secure, we recommend changing this to a unique code that only you know.
Please note: Be careful when entering your PIN. If you enter it incorrectly 3 times, your SIM will be blocked and you’ll need a PUK code to unlock it.
