View the hidden USSD codes on your Android Smartphone

You know them USSD codes - the so-called "hidden codes of Android" and how you can use them?

Οι USSD codes are the characters you type on your phone to access information, diagnostic tests, or access hidden menus.

But let's see what these codes are and how you can use them on your Android devices - with the necessary care to avoid problems.

Let's start by explaining what USSD (unstructured complementary service data) is.

It is a protocol that allows information to be sent across the network. It is possible, for example, to use these codes to put units on your phone in some countries. Thanks to this protocol, we can buy a card, scratch it and enter the code it says to add units to our device for making calls.

In the same way, there are some codes that we can use to access information, diagnostic tests or to access hidden menus on android Smartphones.

Some of these codes may not be available on some models or brands, but you can try them out carefully.

We repeat that special care is needed, because you could lose data or damage your device, and you will use them, only if you are absolutely sure of yourself…
