  • The software and hardware information is readily available on the screen so you can check the phone specs
  • You can validate the IMEI (International Mobile Equipment Identity) and serial number without opening the phone – helpful if you want to network unlock your phone as this is the key information required to retrieve the unlock code

Cons:

  • Battery check could drain the battery fully and sometime damage it altogether

What are the steps to use the code?

The most frequently used (universal) code is to “Display IMEI Number” and the corresponding secret code is *#06#. The code is so popular that it works on almost any make/model of mobile phone including iPhones. The IMEI (International Mobile Equipment Identity) number displayed is a 15 digit number that is uniquely assigned to each mobile phone. IMEI number is also asked while buying and selling mobile phones or unlocking your phone online.

Step 1: First open the default dialer that comes with the phone and enter the code – *#06#

Step 2: The moment you finish typing the code it gets executed and the IMEI (International Mobile Equipment Identity) number is displayed on the screen.

Note: The IMEI number is hidden in the above image as is should always be protected for security reasons.

Maintain caution when using the codes

The codes are designed to be used in certain scenarios and only manufacturer specific codes are to be used with their own brand. Mixing the codes with manufacturers and brands can alter the configuration of the phone and cease working. Using the codes without the knowledge or a purpose might cause harm to your phone as well.

Sometime manufacturers will alter the codes based on different model types so depending on the model you have not all code will work with your phone.
