Code: *31#mobile number

However, that’s not it, since you can still use this code on your iPhone to provide a more granular view of the signal intensity of your network. Bars are a good way to view signal strength, so you can use this code to show signal strength in decibels if you want to know the exact strength. So, here’s how it should be done:

When done, wait for the network to calm down for 20-30 seconds. Then, if the number is over -80 (-70,-60..), the signal intensity is similar to maximum, and if it is below -110 (-120,130..), there is a pretty bad signal on the network. It’s important to remember that, based on whether you are wired to a 3G or 4G network, the signal quality can vary.

You can open the Field Test page again with the secret code to uninstall the decibels and bring back the normal network bars on your iPhone, and tap on the top-left side, which says “Phone,” or you can simply hit the home button once.
