In this article

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: Contact 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.
