    My PUK code isn't working

    • Answer
    • If you have incorrectly entered your PUK (Personal Unblocking Key) ten times your SIM (Subscriber Identity Module) may be permanently blocked and we may need to replace this for you. 

      Please click on the 'Email us' link below and provide a brief description of your query. 

      Important Note
      We will send a replacement SIM card to you if necessary, although Pay & Go™ customers should be aware that if your SIM is permanently blocked, you would need to purchase a brand new SIM.
