SIM PINs and PUK codes: What are they?
If you’re seeing a PUK Lock or SIM Lock error on your device, don’t worry! It’s not the same as a network lock, which prevents a device from being used on another network. We’ll help you unlock your SIM so you can get back to enjoying your phone in no time.
PUK codes
What is a PUK code?
A PUK (Personal Unlocking Key) is an 8-digit code that unlocks your SIM if the PIN has been entered incorrectly three times.
Where to find your PUK code
- Ting physical SIM (pSIM): Check the original SIM card packaging. The PUK code will be labeled.
- Ting eSIM or no packaging available: Chat with us, and we’ll provide your PUK code.
Important: After 10 incorrect attempts, your SIM will permanently lock. Call us if you’re unsure about your PUK code to avoid this.
SIM PIN
What is a SIM PIN?
A SIM PIN is a feature that protects your SIM card from unauthorized use. If enabled, it will require a PIN when:
- Your device restarts.
- The SIM card is removed.
You’ll see a “Locked SIM” message in the status bar if this feature is active.
Unlocking a SIM PIN lock
Enter the PIN set up on your device to unlock. If you don’t remember your PIN, try the default codes: 0000 or 1234.
Note: Ting cannot retrieve your SIM PIN. If you’re unable to unlock your SIM, contact us to order a replacement SIM.
