USSD Codes – Your Quick Phone Toolkit

Ever wonder why dialing *#06# shows your IMEI? Those little star‑and‑hash combos are USSD codes – short commands that talk directly to your phone’s firmware. They’re fast, don’t need internet, and can reveal hidden info or fix tiny glitches in a few seconds.

This tag page gathers all the articles that teach you which codes to use, what they do, and how to run them safely. Whether you’re hunting for battery stats, network strength, or a secret menu, you’ll find step‑by‑step guides right here.

Common USSD Codes for Android Phones

*#*#4636#*#* – Opens the Testing menu where you can see detailed battery, usage, and Wi‑Fi info. Just type it in the dialer and hit call.

*#0*# – Brings up a hardware test screen. You can check the LCD, touch, sensor, and speaker without any app.

*#06# – Shows your device’s IMEI number. Handy if you need to register your phone or block it when it’s lost.

*#*#7262626#*#* – Displays a list of all installed apps. Great for cleaning up unused software and freeing storage.

*#*#4986*2650588#*#* – Gives you the complete firmware version, kernel, and build details. Useful when troubleshooting or updating.

Using USSD Codes for Network & Battery Checks

If you’re tired of weak signal bars, try *#*#4636#*#* again and tap the “Phone Information” tab. It shows real‑time signal strength in dBm, letting you spot dead zones.

To see how healthy your battery really is, dial *#*#3424#*#*. This code opens a hidden battery health screen with charge cycles and capacity percentages.

Running *#*#7262626#*#* can also reveal which apps are using the most data. Knowing that helps you cut down on unnecessary background usage and improve speed.

When you need to reset the network settings without wiping everything, use *#*#7780#*#*. It clears carrier info and restores the default network configuration, which often solves dropped call issues.

All these codes work on most Android devices out of the box. iPhone users have a smaller set, but *3001#12345#* opens the Field Test mode where you can view signal metrics similar to Android’s testing menu.

Remember, USSD codes are read‑only unless you’re in a hidden menu that allows changes. Don’t change settings you don’t understand – you could end up resetting important data.
