Secret iPhone ‘code trick’ reveals EXACTLY where best signal in your house is


A TIKTOK tech tipster has shared a neat way to find the spot in your house with the best mobile phone signal.

In a video on Tuesday, user “Tapsmart Tom” showed how to access a hidden menu on iPhones that gives a more detailed look at your local signal strength than the traditional bars at the top of your display.


Your iPhone has a secret menu that reveals your signal strength

All you have to do is open the dial pad and type *3001#12345#*.

Tap the call button and you’ll see a section of the iPhone not accessible through the usual settings.

It’s actually designed for engineers to get in-depth information about your smartphone’s connection.

But it’s still good to have a nose at.

While you may not be able to make sense of most of it, there are some useful parts.

For example, try to find a bit called LTE RSRP, which stands for Reference Signal Received Power.

This shows your true signal strength by providing an accurate measure of your distance to the nearest cellular tower.

It usually goes from -140 to -40, and the closer you are to -40 the better.

This is actually the data that is used to work out what your phone’s signal bar shows.

But most of the other features are meant for techy types and aren’t much use to everyone else.

In fact, the so-called Field Test Mode has been lurking around for years.

Android owners can find theirs by going to Settings > About phone > Status > SIM status > Signal Strength.

Tapsmart Tom’s video has already racked up more than 80,000 views on TikTok.

“This is a really accurate way to find the signal hotspots in your house,” he said.
