These simple codes will give
you access to your iPhone settings secrets
Most of us do not know, but it turns out that
the iPhone has a hidden menu, called "Field Test", which can be
accessed by entering a code a unique code for a specific feature.
This hidden menu is a really important tool,
which allows you to view additional information about the connection of your
iPhone to the internet. The menu can be activated by entering the following
code: *3001#12345#* and then pressing the Call button. Then, your iPhone
will show a gray screen, and you will see all the extra information related to
your iphone internet connectivity.
One of the most useful information that
appear is a signal strength indicator more detailed than the five points that
we can currently see at the top left of your screen.
Now, in place of the points we will see a
figure, which is the cellular reception expressed in dB. The smaller the
number, the better the signal. For example, -50 would mean that the signal is
perfect, the equivalent to the five points, while -105 I would like to say that
we would not have signal.
You might not see these figures while you are
using your iPhone generally,If you want do not disappear when you return
to the normal display of the phone you only need to press the power button
of your iPhone until you exit the slider to turn it off. When you exit releases
the shutdown button and press the Home button until you see your home screen,
then you will see as the coverage points have become the numbers that described
in the preceding paragraph.
In this way we will open the function, and
the best thing is that we will be able to switch between the two ways to
view the signal simply by playing on the same and choosing the way in which
we want to see it. Try it very simple.
There are also a number of other codes that
offer other information:
*#33# displays the status of your call barring settings. This tool
can be activated and deactivated by typing *33*PIN# and #33&PIN#,
replacing "pin" by the PIN number of your SIM card in the
iphone you put in your iphone.
*#43# will tell you if you have call waiting enabled. This function
allows you to receive an alert if a call comes in when we are talking on the
phone, and the on hold until we are able to help her. Can be activated by
dialling *43# and deactivated with #43#
*#06# will show you your identification number IMEI.
