The USSD codes on Android are not that secret codes that will help us nerds, to make toy with our smartphones, even to bricker sometimes. They can be useful for accessing information about your device, for development or to perform actions quickly.

Android, what is that?

The USSD codes

They are often confused with secret codes on Android. First, USSD stands for Unstructured Supplementary Service Data, which is in French Supplementary Service for unstructured data. It is a protocol that allows to send information via GSM, 3G or 4G networks. The idea is to be able to trigger actions remotely, sending a precise code for each.

Are developer options advantageous for Android?

To enter them, it is enough to proceed directly from the pad of the application of call. They usually begin and end with a sharp or an asterisk. You can find a list with your operator, such as Orange. Some orders have been standardized and are available worldwide, unchanged. For example, they can program a call transfer.

You can request information from your service provider’s servers

You can request information from your operator’s servers thanks to them, that’s all. They work on the same level as Android’s own secret codes, so it’s easy to confuse them.

In practice, it is traditionally used to request information from its mobile operator. You may know the famous # 123 # from Orange, which allows you to know the balance of his credit. It’s a USSD code!

The hidden face of USSD codes

This is less true now, but at one time some experts were telling the alarm bell about the possibilities of exploits on Android. The protocol can be used for malicious purposes by applications or even sites.

End of 2012 for example, a scandal to hit the flagship Samsung. They were vulnerable to a factory reset code, which could be launched directly from a web page. That said, I do not see too much interest in the author of this hack, for the blow.

Android USSD codes

They have a peculiarity, they always end with a sharp, but usually start with an asterisk. Unlike USSD codes, you do not need to be connected to the network to activate them: logic, they act directly from and on the Android system.

They are actually stored in system files and depend on the version installed on the Smartphone. Many codes have become obsolete in passing to Android 4.3 Jelly Bean. The most interesting of them is by far the menu of information on the phone.

Also, note that since the arrival of Lollipop some codes are deletes, others implement. We keep the list up to date when we get info, regularly.

It should be noted that some manufacturers are adding their grain of salt with new codes on some of their terminals. We are trying to give you as complete a list as possible. It will eventually be updated when we discover new secret codes.

Warning: these USSD codes can cause you to lose your data or even make your smartphone unusable. Most of the menus are in English and include terms that are incomprehensible, even perplexing to average people. Apply the most basic rule to do-it-yourself: if you do not know correctly what you are performing, it is better to not do it.
