20+ Best Hidden Codes
You have to enter these secret codes into the dialer to find out about the device, how to hide calls, fix problems, etc. So, let’s check out some of your iPhone’s secret dialer codes
Field Test Mode
*3001#12345#*
This code is the one you need to use if you want to find out basic information about your network. With this iPhone secret code, you can find out how strong your network signal really is in decibels.
- First, make sure that your iPhone has an active cellular connection.
- Next, open the phone app and enter the code on the dialer
- On the Field test menu, tap on the LTE.
- On the next screen, tap on the Serving Cell Meas.
- Now, on the next screen, look at the numerical measurement behind rsrp0
The numbers after the rsrp0 are the strength of your iPhone’s cell signal in dBm.
For those who don’t know, the signal strength is good if the numbers behind rsrp0 are between -50dB and -60dB. Between -70dB and -90dB, the signal strength is good. If the number is greater than -100dB, it means the signal strength is weak.
Enter Field Test Mode in iOS 10 or Earlier
