I just purchased a new phone and found that it was locked to AT&T. What is a locked phone?

Phones that come with calling plans and are purchased through a specific carrier are often considered to be ‘locked’. The carrier has set up the software used on the phone so that it is locked to that specific carrier, meaning that the phone will work with a SIM card from that carrier only. The lock is known by various names like SPC Lock, SIM Lock or Sub Lock.

Why is my phone locked to AT&T?

Your service provider, AT&T, has enabled the network restriction so that you are unable to use your phone with any other GSM network. The manufacturer has locked the cell phone to AT&T.

What can I do with my phone that is locked to AT&T? How can I start using it again?

The safest and most reliable way to get your locked phone working again is to use unlock codes.. Unlock codes are phone specific codes that can remove the network restriction.

If I use unlock codes in my phone can I use it with another service provider?

If you use unlock codes from a reputable unlocking service provider, your phone will be permanently unlocked without affecting any of the phone’s software. You can then start using your phone with any other compatible GSM network.

Where can I get unlock codes that will unlock my AT&T phone?

You can get unlock codes from GSMLiberty. We are a reputable company and have been providing an unlocking service for various phone models locked to different carriers for some years now.

How do I find the IMEI number in my phone?

Here are two methods to find the IMEI number of your phone:

  1. Remove the battery and look for the 15 digit IMEI number present on the label which is located underneath the battery.
  2. Dial *#06#* while the phone is powered on. The 15 digit IMEI number will be displayed on the screen.

Why is it important for the IMEI number to be valid?

Our code generator provides codes for valid IMEI numbers only. If the number is not valid, we will not be able to generate an accurate code for your phone.

What will be the effect of using the AT&T unlock codes on the phone?

After you enter the unlock codes that you receive from GSMLiberty, your phone will be unlocked and you will be free to use any compatible service provider of your choice.

How do I tell whether my phone is locked?

Before placing an order for the unlock codes, be sure to find out whether or not your phone is locked. Here are some simple ways to find this out.

  1. Check for the mobile carrier’s logo on the phone box, handset or start-up screen.
  2. Check whether the logo of the phone carrier is present on the phone.
  3. Check whether the logo of the phone carrier appears on the screen every time the phone is switched on.
  4. There are various menu items related to the phone carrier within the phone itself.

One final way to check is to get a SIM card from a different network and place it in your phone. If the phone is unlocked, it will turn on normally with all the features getting loaded properly. The name of the phone carrier will also be displayed on the screen. If it is locked, an error message will be displayed prompting you to enter a SIM Network Unlock Pin.

What is the procedure for using the unlock codes to unlock my AT&T phone?

In most cases the procedure is as simple as inserting a non-allowed SIM card and dialing the unlock code when prompted.
