FIELD TEST mode is an interesting feature which allows users to see their phone-signal strength measured in numbers, with the number going up and down depending on signal.
A value above -80 is a full-bar strength, but anything below -110 is very weak. This is a more accurate way of seeing whether you have enough signal to make a call, rather than holding on to hope with one-bar.
We advice you to be careful and don’t tamper or do what you don’t understand with the codes as using the secret codes on your iPhone is totally at your own risk.
