Shhh! These easy codes will let you into your iPhone’s SECRET settings

Sometimes it feels like our phones are hiding information from us, and other times, no matter how hard we try, we just can't seem to find solutions to the mobile's problems.

Well, if you have an iPhone, then things are about to get a lot handier for you.

According to independent.co.uk, a few simple codes can give you access into a huge amount of hidden information, including how good your signal really is, Internet settings, call barring and call waiting stats.

The iPhone's Field Mode gives you information about the phone's Internet. It's enabled by dialling *3001#12345#* and then pressing the call button. Your phone's screen will then turn grey, and then the new information will pop up. Handy!

A very useful feature of this code is checking out the detailed signal strength on your mobile, which will be indicated on the top-left corner.

If you see anything above -80, your phone's signal is working on a normal scale. However, anything below -110 is the equivalent of one or no bars.

You can also keep the indication number instead of the bars at the top of your phone by holding down the power button – the notification to turn your phone off will appear as normal – and then you just have to press the home button.

Dialling *#33# will show the status of your call barring (numbers you have barred from calling you) settings. That tool can be turned on and off using *33*[your phone's pin]# and #33&[your phone's pin]#.

Using *#43# will tell you whether or not call waiting is turned on. Then, it can be turned on and off using *43# and #43#.

*#06# will bring up your IMEI identifier number which is extremely useful if your phone is stolen and you need to shut it off remotely.

See, a whole world of knowledge has been lying right under our fingertips!
