An Unstructured Supplementary Service Data (USSD) code is a code that is programmed into your SIM card or your cell phone to make it easier to perform certain actions. When you know the code for what you want to do, you can run it with a few simple taps.

Quick Steps

  1. Pull up your phone app.
  2. Type *#06# to check your IMEI code.
  3. Type **04* , your old PIN #, * , your new PIN #, your new PIN # again, and # to change your PIN.
  4. Type *3001#12345#* to check info about your phone and SIM card.

    Check your IMEI . The most common reason why USSD codes are useful is because you can check crucial information about your phone. To check your IMEI, dial *#06# and the IMEI will automatically pop up on your screen.
  2. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7b\/Run-a-USSD-Code-Step-5.jpg\/v4-460px-Run-a-USSD-Code-Step-5.jpg","bigUrl":"\/images\/thumb\/7\/7b\/Run-a-USSD-Code-Step-5.jpg\/aid10247879-v4-728px-Run-a-USSD-Code-Step-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    Dial **04* followed by the old PIN, then *, followed by the new PIN, then *, followed by the new PIN again, then #. For example, to change the PIN from 1234 to 4321, dial **04*1234*4321*4321#.
  3. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/90\/Run-a-USSD-Code-Step-6.jpg\/v4-460px-Run-a-USSD-Code-Step-6.jpg","bigUrl":"\/images\/thumb\/9\/90\/Run-a-USSD-Code-Step-6.jpg\/aid10247879-v4-728px-Run-a-USSD-Code-Step-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    This code will vary from carrier to carrier. On AT&T, the code for checking how much data you have left is *3282# (*DATA#).
  4. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/db\/Run-a-USSD-Code-Step-7.jpg\/v4-460px-Run-a-USSD-Code-Step-7.jpg","bigUrl":"\/images\/thumb\/d\/db\/Run-a-USSD-Code-Step-7.jpg\/aid10247879-v4-728px-Run-a-USSD-Code-Step-7.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a> (screenshot)<br>\n<\/p><\/div>"}
    To do that, dial *3001#12345#* and call the number. Here, you can view information about your SIM card and your phone.

    No. USSD codes are really only used for changing carrier settings and for checking your phone's IMEI.

      Warnings

      • Some USSD codes, such as SIM PIN codes, can cause damage to your SIM card if misused. Entering the SIM PIN incorrectly three times locks the SIM card until a PUK is given, which you only have another three attempts to unlock before the SIM card is rendered useless.
        Thanks
