Unable to do anything beyond tuning my phone on /Puk code needed

The phone didn't recognize my code and now I can't do anything beyond turning it on. This is the second att phone I've gotten in 2-3 weeks yet have only had use of 1 for a few hours. I don't think I'm going to be happy in my recent change of providers

Being locked out of your phone with a screen lock or a PUK lock has nothing to do with service provider you're using.

The PUK code is a code that locks a particular SIM card to a particular phone. This prevents someone from stealing your sim card and using it in a different phone and using up your service. Since it is specific to the phone, each time you get a new phone you have to have the PUK code when you move your sim card.

The screen lock prevents somebody else from being able to access the contents of your phone by opening up the screen. Whenever you turn off your phone you may be required to enter the full PIN code even if you have set up an alternate method for unlocking your phone, like swipe, Biometrics.  

Set a pin you won't forget.

We are here to help provide you with your PUK code, @Sabrinajohnson1975.


We do understand how important it is to be able to use your device. This is definitely not the experience we want you to have. Here are the steps to unlock a SIM card with a PIN unlock key (PUK):

  1. Go to your account overview and open the My wireless section.
  2. Scroll to My devices & add-ons and choose the device that needs a PUK code.
  3. Select Manage my device.
  4. Under See device options, select Get your PIN unlock key (PUK).

If your device displays PUK2 or PUK blocked call operator, then the wrong PUK code was entered 10 or more times in a row. The SIM card is blocked and must be replaced. You may pick one up at your local AT&T Store, or we can have one shipped out to you. 


Try this and let us know how it goes!
