If you're wondering what exactly secret codes are, well, these are USSD codes that provide some information when you dial them from your smart phone. Android smart phones come with their own set of secret codes, but each different smart phone comes with its own set of codes, derived from its manufacturer and, therefore, it is a difficult task to keep track of them.

Code: * 3001 # 12345 # *

However, that is not all, since you can also use this code on your iPhone to get a more detailed view of the signal strength of your network. The bars are a good way to see the intensity of the signal, but if you want to know the exact intensity, you can use this code to see the intensity of the signal in decibels . So, here is how to do it:

Then just press and hold the Power / Lock button to unless you get the option "Swipe to turn off" . Once you are on the power off screen, simply press and hold the start button and see the bars replaced with the power of the network in decibels.
Once this is done, wait 20-30 seconds for the network to establish. Then, you can take note of the intensity of your seal. If the number is greater than -80 (-70, -60 ..), the intensity of the seal is almost full and it is less than -110 (-120, 130 ..), The network has a seal quite weak . It is important to keep in mind that the signal strength varies depending on whether it is connected to a 3G or 4G network.
