FIXING A BLOCKED PUK: An Incredibly Easy Method That Works For All


A PIN code on your SIM card helps protect your phone's data.
For the safety of wireless subscriber’s data and monetary investment, many GSM phone manufacturers (such as AT&T and T-Mobile) provide an option to place a PIN lock on a SIM card. This PIN lock keeps strangers from accessing what’s on the SIM card or making calls with the locked phone. If you enter an incorrect PIN code three times, a PUK (Pin Unlock Key) code will be requested. This number is provided by the service provider.

Take the battery cover off of the blocked phone and remove the battery.

Write down the phone’s IMEI and SIM card number. The IMEI can be found on a sticker behind the phone’s battery (which you’ve already taken out). The SIM card number is printed on one side of your SIM card.

Put the phone back together and power it on.
Call your wireless provider from another phone and ask to speak with someone about PUK unlocking.

Provide the representative with information from the phone and SIM.

Put the given code into the PUK lock screen to unlock your phone and SIM.

How to Retrieve a T-Mobile Pin

Each T-Mobile phone comes with a SIM personal identification number (PIN) that you must enter before you install a new SIM card into the phone. Although the default PIN is 1234, you can change it at any time. After you change the SIM PIN, you must remember it. If you fail to do so, the phone will block the SIM and require a PUK code to make any changes to it. To retrieve your PIN, you’ll have to enter the correct PUK code, which you can get from a T-Mobile Customer Care agent.

Call T-Mobile Customer Care when your phone asks for the PUK code (see Resources). Give the representative the security information on the account, including the account holder’s name and address and the last four digits of his Social Security number.

Explain that you’ve forgotten the phone’s PIN and have reached the maximum amount of attempts to enter it. Write down the PUK code given to you. End the call.

Navigate to the SIM of your T-Mobile phone. Enter the PUK code when prompted. Press the “Enter” key.
Enter your new SIM PIN twice when prompted and click “Done.”

How to Unlock a Samsung by Verizon

Verizon Wireless is one of the largest cell phone providers in the United States. Most Verizon Wireless phones can be used on other service providers, if you can unlock the phone by obtaining the subsidy unlock code, or SUC.

Step 1

Call your service provider’s customer service line. Most cell phones have the customer service number preprogrammed as 611. If your phone doesn’t, you can find the number on your phone bill or the Verizon Wireless website.

Step 2

Explain to the customer service representative that you would like to unlock your phone for use on another network. If you purchased the phone for the no-contract price, which is usually two times more than the price for purchasing the phone under contract, you will be given the SUC, which you need to unlock your phone. If you purchased the phone under a contract, you are legally required to carry out the agreed contract and will have to prove to the customer service representative that they should unlock your phone for you.

Step 3

Turn your phone off when you’re ready to unlock it. Power your phone back on and hold down the factory settings keys. For most phones these are star (*) and one (1), but if this doesn’t work, check your phone’s user manual for the correct keys. The phone will start up and give you a blank screen with a text entry box. Enter the SUC in this box and press send. The phone will now turn off.

Step 4

Remove the SIM card, which is normally located behind the phone’s battery, and put in the SIM card for the service provider you wish to use. Power the phone on and place a test call to make sure that everything is working.

How to Check the IMEI on a Samsung Phone


You must stop surfing and turn off your phone to access the IMEI number.

The serial number for your Samsung phone, usually referred to as the IMEI number, helps customer service representatives help you troubleshoot problems with your phone. It’s also necessary if you want to unlock your phone using a specific character. The number displays in the same location on all Samsung phones — under the battery.

Getting Behind the Battery

To access the IMEI number, turn off your phone and remove the back cover. Take out the battery to expose the Samsung stickers hidden underneath the battery — the stickers are on the phone, not the battery. Look for a line of numbers under a bar code that’s labeled “IMEI” on most phones. For phones that work on the GSM network, the IMEI number should be 15 characters long. On the CDMA network, you’ll see only 11 numbers. Also called the ESN, or electronic serial number, the sticker might not say “IMEI,” but it should be the longest string of numbers on the sticker.

How to Disable the Caller ID on an iPhone

Step 1

Tap “Settings” on the iPhone’s home screen.

Step 2

Tap “Phone.”

Step 3

Tap “Show My Caller ID” in the Calls section.

Step 4

Tap the “ON/OFF” toggle next to Show My Caller ID until “OFF” appears. Your phone number now appears as Private.

How to Format an SD Card in a Cell Phone
