Locking and unlocking your mobile

To stop other people from being able to use your phone, set up your phone with a passcode. Find out how to set up a passcode in your mobile's user guide. If you lock yourself out of your phone, you'll need your PUK code.

PIN and PUK codes

  • Your mobile's SIM card has a security PIN and a PUK code. The default PIN is usually 1234. To change this, check your mobile's user guide.
  • Your PIN is a code that keeps information on your mobile safe by locking your SIM.
  • Use the PUK code to unblock your SIM if you enter your PIN wrong three times.
  • The PUK code is on the surrounding plastic that your SIM card was in. If you've lost this piece of plastic, you can still find when you sign in to MySpark.

Find PUK code and unlock SIM card

  1. Sign in to MySpark.
  2. Select Products and services.
  3. Scroll down and select your phone number from the drop-down.
  4. The PUK code for this number will show. Note: If you enter the wrong PUK code 10 times, it'll block your SIM card and you'll need to get a new one.

Important notes about Device Insurance

  • You may see more than one charge on your bill for Device Insurance. This may be because you've recently purchased a new mobile but haven't indicated to Spark that you want to end the insurance on your previous phone. Spark assumes that you may still be using this phone. To cancel the insurance on a previous mobile phone follow the instructions on this page under Cancel your Device Insurance.
  • If you lose your phone, or it's damaged, while you're overseas you may be able to get money back on your loan phone. When you return to NZ, you'll need to make a claim and provide proof of the costs you've faced.
  • If you find a phone you've made a claim on, contact us on 0800 SPK INS (0800 775 467).
  • Your insurance only covers you if your account is up to date.
  • All claims management is handled by Chubb Insurance New Zealand. To lodge a claim, call 0800 SPK INS (0800 775 467). Claims need to be lodged within 30 days from the date of accidental damage or loss. For full details,  View Spark's Device Insurance Policy
