And those four little signal bars at the top? Basically meaningless. Want the real signal strength? Open your Phone app and dial this: *3001#12345#*, then hit call.

You’re in Field Test Mode.

Is this for I-Phone or Android?

Android’s Field Test Mode is a diagnostic tool that shows detailed network information and allows for hardware testing. To access it, you can either go through the Settings menu, typically under About Phone > Status or Network, or by dialing a secret code like *#*#4636#*#*. While the specific method can vary by device, these options provide access to signal strength (measured in dBm, where numbers closer to 0 are better), network type, and other technical data.

Methods to access Field Test Mode

Via Settings:

Go to Settings.

Navigate to About Phone or About Device.

Look for Status, Network, or Mobile Networks to find your signal strength (dB reading).

Via secret code:

Open the phone’s dialer.

Type in a code, such as *#*#4636#*#*, and press call. Note that this code may not work on all devices, but
it’s a common one to try.

Some specific codes exist for certain brands, like ##33284# for some HTC models.
