IF YOU’VE ever found yourself wandering around trying to find better signal then you might want to try this iPhone trick.
A viral YouTube video explains how a “secret sub-menu” on your iPhone can turn your signal bars into numbers so you can see when your signal is getting better or worse.
The video is courtesy of popular YouTube channel Josh Connects.
In the voice over users are instructed to go to their iPhone keypad and enter the code: “*3001#12345#*”.
One you’ve typed out all those symbols and numbers you then click the green call button.
A hidden menu should pop up on which you’re instructed to click “LTE”.
The presenter then clicks “Serving Cell Meas”.
He then explains: “Now what these numbers mean, they’re your service strength”.
The video explains how the number you see at the top should be as close to zero as possible to indicate good service strength.
If you move your phone around you should notice the number change.
Apparently “negative 50” or “negative 40” means good service.
However, “negative 140” means no service at all.
