We’ve rounded up some of the best codes for you to try.

The number is also useful if you are trying to find a lost or stolen iPhone.
To find your IMEI number, go to your keyboard and enter *#06#.
The number should just appear on your screen.
Code to find stronger signal
A viral youtube video explains how a “secret submenu” on your iPhone can turn your signal bars into numbers so you can see when your signal is improving or deteriorating.
In the voiceover, users are prompted to access their iPhone’s keyboard and enter the code: “*3001#12345#*”.
Once you have typed in all these symbols and numbers, you then click on the green call button.
A hidden menu should appear where you are prompted to click “LTE”.
The presenter then clicks on “Serving Cell Meas”.
The video explains how the number you see at the top should be as close to zero as possible to indicate good serve strength.
If you move your phone, you should notice the number change.
Apparently “50 negative” or “40 negative” means good service.
However, “negative 140” means no service at all.

There are different codes for this depending on the situation of the call you want to forward.
If you want to forward a call when you do not answer, dial *61*.

Next, enter the number you want calls forwarded to and type # then the green dial button.
To deactivate, dial the code initially entered and press call.

Press the green dial button.
This feature can be useful if you let someone borrow your iPhone but don’t want them to make outgoing calls.
