Many of us do not know how to show iphone signal strength in numbers. Most of us consider measuring it with the help of the bars on top which may not be precise. You will be amazed to hear that there is a secret setting in your iPhone which would help you find its correct signal strength. And the strength would be in decibels, that is, it would be stronger if it’s nearer to zero.
The signal strength is indicated by the following values:
-50 to -75: Excellent Signal Strength
-75 to -90: Good Signal Strength
-90 to -110: Fair Signal Strength
-110 or below: Poor Signal Strength
Even if you keep moving about, this number will keep changing and give you the exact value of the strength. Given below are some tips to help you find out how to show iphone signal strength in numbers rather than in bars:
1). Dial the following number on your iPhone and press call: *3001#12345#*
2). You’ve got your iPhone in the Field Test mode now. Check for a signal strength value on the upper left hand corner. You have two options – If you want to go back to the bars system, tap on it and if you want to have the number indicator, go to the next step.
3). Hold on to the power button till you see the bar that says ‘slide to power off’. But, don’t power off your iPhone.
4). Then press the home button again until you exit from the app get back to the home screen.
You’re finished with the process. Again if you want to go to the original signal strength representation, dial *3001#12345#* and press ‘Call’. You will enter the field test mode again. Then press the home button and you’ve done it.
