In this article, we will guide you on how to change iPhone signal bars to numbers. This is not a new trick, and you don't need to jailbreak or deeply interfere with the system. Refer to the steps below for more details.
Changing iPhone signal bars to numbers
Step 1: Begin by opening the iPhone dialer app, then enter *3001#12345#* and press call.
Step 2: After making the call, your iPhone will enter Field Test mode. Here, you'll notice the signal bars replaced by negative numbers. According to Cnet, values around -113 indicate weak signal, while those near -50 indicate strong signal.
Step 3: Finally, press and hold the power button until the device displays “Slide to power off.” Instead of sliding to power off, release the power button and press the Home button for 5 seconds until Field Test mode exits completely. After this step, you've successfully changed iPhone signal bars to numbers.
That's how you can change iPhone signal bars to numbers. To revert back to the 5-bar signal as usual, simply follow the same steps mentioned above. However, when in Field Test interface, press the Home button to exit instead of the power button as mentioned.
