iPhone Field Test Mode
Accessing Field Test Mode on the iPhone is relatively simple, just open the Phone app, switch to
the keypad and dial the following code: *3001#12345#* and then press call. If you dialed it
correctly, your iPhone will enter Field Test Mode and you’ll see the numerical value for signal
strength in the upper left hand corner of the screen where the signal strength was previously
displayed in bars. To exit and return your iPhone to normal status, all you need to do is hit the
Home button. The mode is available on any iPhone running iOS 4.1 and all later versions.
Android Field Test Mode
Accessing Field test mode on Android phones is also straightforward. You simply need to
find your way to “Settings” > “About Phone”, and your numerical signal strength will be
available under either Network or Status, depending on the model of the phone you own.
