In the meantime, "Clive" sent me an email about tips and tricks for mobiles (or cells) and I thought I'd share my thoughts with them.
FIRST112 is the international emergency number. A good tip with regards to emergencies is to have a contact in your phonebook "ICE" (in case of emergency) with someone's number that can be phoned. This was used extensively in the 7/7 bombings, but is now taught at all motorcycle training centres as well.
The Emergency Number worldwide for Mobile is 112.
If you find yourself out of the coverage area of
your mobile; network and there is an emergency,
dial 112 and the mobile will search any existing
network to establish the emergency number for you,
and interestingly this number 112 can be dialled
even if the keypad is locked. Try it out.
SECONDThe remote unlocking isn't true, in fact it's twoddle of the highest order. Most cars now use radio frequencies, and all that would cover is audible frequencies.
Have you locked your keys in the car?
Does your car have remote keyless entry?
This may come in handy someday.
Good reason to own a cell phone: If you lock your
keys in the car and the spare keys are at home,
call someone at home on their mobile phone
from your cell phone.
Hold your cell phone about a foot from
your car door and have the person
at your home press the unlock button,
holding it near the mobile phone on their end.
Your car will unlock.
Saves someone from having to
drive your keys to you.
Distance is no object.
You could be hundreds of miles away,
and if you can reach someone who has
the other 'remote' for your car, you can
unlock the doors (or the trunk).
THIRDThis also untrue, but like most myths there is a grain of truth behind it. All Nokias can have the quality of their calls reduced, and this is the keypad shortcut to do it. If the quality is less, then the power used is less, so the battery lasts a bit longer. Typically 5% is quoted.
Hidden Battery Power
Imagine your mobile battery is very low.
To activate, press the keys *3370#
Your mobile will restart with this reserve and the
instrument will show a 50% increase in battery.
This reserve will get charged when
you charge your mobile next time.
FOURTHAs for the stolen mobile phone trick, typing *#06# brings up your unique identifier of your phone, called the IMEI number. This number is barrable by all mobile phone operators. And for the pin number thingy, I think you'll find more truth by sending me your card and your pin number, so we can test it ;-)
How to disable a
STOLEN mobile phone?
To check your Mobile phone's serial number,
key in the following digits on your phone: * # 0 6 #
A 15 digit code will appear on the screen.
This number is unique to your handset.
Write it down and keep it somewhere safe.
When your phone get stolen, you can phone
your service provider and give them this code.
They will then be able to block your handset
so even if the thief changes the SIM card,
your phone will be totally useless.
You probably won't get your phone back,
but at least you know that whoever stole it
can't use/sell it either.
If everybody does this, there would be
no point in people stealing mobile phones.
ATM - PIN Number Reversal - Good to Know
If you should ever be forced by a robber to
withdraw money from an ATM machine, you can
notify the police by entering your PIN # in reverse.
For example, if your pin number is 1234,
then you would put in 4321.
The ATM system recognizes that your PIN number is
backwards from the ATM card you placed in the machine.
The machine will still give you the money you requested,
but unknown to the robber, the police will be
immediately dispatched to the location.
