Have you ever come across "secret codes" for phones that usually begin with "#"? These codes have been around for a long time and can still be used today to access hidden settings and information. In this article, we’ll explain what these codes are and reveal some of the most important ones.

These codes fall into two main categories: USSD codes and MMI codes. While they might not be particularly useful to the average smartphone owner, these hidden codes can be fun to try out once in a while to satisfy your curiosity. The purpose of this article is to provide a comprehensive list of these secret codes for Android devices.

Before diving in, it’s helpful to understand what these codes are and the key differences between MMI and USSD codes. However, if you're in a hurry, feel free to skip ahead to the section where we explore specific smartphone codes.

I still remember how amazed I was when I first got hold of the Nokia 3210 back when I was a kid, and it was during that time I developed my love for technology, particularly for mobile phones. I started sharing my knowledge through writing in different blogs and forums back in Nokia Nseries era. I even make videos before where I put different phones side-by-side. Today, I'm still an avid enthusiast of smartphones, but my interests have evolved into smart devices and electric vehicles.

    These were far more useful in the days of dumb phones. With smart phones, this is pretty esoteric or info otherwise available in the app or irrelevant. Most prepaid deals offer unlimited talk and text for the most part anymore.
