It refuses to come on.

Try changing the sim card. The sim card might be faulty since the new 4G phones use the micro sim cards or the newer versions of the sim cards. Try a new sim card and that should work.

PUK Codes

A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.

Since I don't know the name of you carrier, I'm using AT&T as an example. Most carriers use the same methodology though the wording may be different.

You can obtain your phone's PUK code from AT&T in one of these ways:

• Log in to myAT&T online
• Use our Technical Support Chat.
• Contact Customer Care


To get your phone's PUK code online:

? Log in to myAT&T.
? From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading.
? From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.
? The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.

Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."

You can also do it without any assistance from anyone, However, be sure to read the following carefully because there are pitfalls.

Although most people remember their primary SIM PIN code, those other codes - used for various verification purposes - are never to be found when needed. Below we've included a set of short codes which, when entered on a handset's standby screen, will let you easily change PIN and PUK (short for Pin Unlock Code) codes - but keep in mind, they may not work with all handsets and mobile operators.

More importantly, when changing ones PUK codes there'll be no help to get from the mobile operator if the new codes are forgotten, so make sure to write any changes down alongside the old PUK codes. Also, please note that the codes should be entered without the spaces shown below.

Change SIM Card PIN

** 04 * old PIN * new PIN * new PIN #

Change SIM Card PIN 2 (Write down the new code)

** 042 * old PIN * new PIN * new PIN #

This was wordy but hopefully it helped you.
