Hi ​@Hitesh316uk ,

I’m sorry to hear you’re having trouble with your SIM being blocked. I know that can be really frustrating. I’ll help you get this sorted.
 

If your SIM is asking for a PUK code, it usually means the PIN was entered incorrectly too many times. Here’s what you can do:

1. Log in to your iD Mobile account (app or website)
   Go to My Account > My SIM / Device
   Your PUK code should be displayed there
   
   2. Enter the PUK code carefully
   You’ll be prompted to enter a new PIN after
   Be careful: entering the wrong PUK too many times can permanently block the SIM
   
   3. If you can’t log in
   Contact us on 0800 049 1300 from another phone
   We’ll verify your account and provide the PUK code
    

If you’re still stuck, let us know and we’ll guide you step by step.
