There are a number of different ways your phone can become blocked. Here's what to do.
Have you entered the wrong PIN code several times?
Your SIM card will block itself and ask for your PUK code. You can find your PUK code in your SIM card wallet.
Don't have your SIM card wallet? If you've already signed up for My T-Mobile, you can easily access your PUK code online. Here's how.
Step 1) Sign up or log in to My T-Mobile
Step 2) Select Phone
Step 3) (If there's more than one mobile on your account, click on the mobile number you wish to find out the PUK for - if there's only one mobile on your account, go straight to step 4)
Step 4) Select Unblock SIM
Step 5) Click beside If your PIN code is locked
Step 6) Your PUK code will display. Enter this into your phone to unblock your SIM
Tip: If you enter the wrong PIN 10 or more times, this will LOCK your SIM card and you will need to replace it. To order a replacement SIM card call us on 0845 412 5000 (Charged at local toll rates) or if you have access to another T-Mobile phone, simply dial 150.
