Myths about Cell Phone Emergency Uses

Spread the love

This post is by Bernie Carr,

I collected a series of emails about cell phones’ emergency uses and finally got a chance to research and test them.

The following tips sounded so promising but turned out to be myths after all:

  1. If you get locked out of your car, call someone at home and have them find your spare key.  Sound the clicker to unlock your cell phone from afar.  I first tried this by parking the car a few doors away.  It seemed to work but it turned out the normal clicker radius still covered where I was parked.   Once I parked the car a few blocks away this did not work.   I started to research this online and it turns out the Mythbusters team tried it too and this idea was “Busted”   You cannot unlock your car using your cell phone.
  2. Dial 1-1-2 anywhere in the world to get emergency help.   I researched this one and there may be some areas (such as a few places in Europe) where 112 will direct your call to the emergency line but it is not universally true everywhere.  Don’t count on it, 9-1-1 is still the number to call for emergencies.
  3. Dialing *3370# when your cell battery is low will “unlock” reserve battery power.  Not true, you need to keep your cell phone charged at all times.
  4. If you press *#06#  you can find out your secret cell phone code; keep the code in case it ever gets stolen so you can disable it remotely.  The easy way to disable a stolen cell phone is to call your cell phone service provider to report the theft.  Give them your phone number and they will take care of it.  That’s why it’s a prudent habit to keep a written list of important phone numbers in a safe place.

This one is TRUE:  Inactive cell phones can still call 9-1-1

The one thing that is true is you can use a charged cell phone, even though it no longer has cell service, to make an emergency call.  However, the cell phone must be properly charged to make the 911 call.  (Do not call 911 just to test it.)  Don’t throw away that old cell phone that you just disconnected from service:

  • Keep it (along with the charger) in your glove box as a spare cell for emergency
  • Save the phone and the charger; give it to someone to use as an emergency
  • Donate it.  AT&T and other cell stores have a donation bin.

    1. I got one of those chain emails and it sounded good, but I thought I better test and or research before I passed it to anyone. Thanks milleniumfly.

  1. 112 is the GSM standard emergency number and will be translated by the handset to the emergency number appropriate to the assigned network. It works all over Europe, and most of the rest of the world (I do believe USA being an exception). 911 works in the UK and Ireland, as does 999.

    *#06# provides your IMEI number on nearly all makes and models of phones, required to at the handset to a block register (stolen, lost, etc.)

    Phones with no sim can still call emergency services.

  2. To be clear. In the UK? These 4 numbers will get you through to the emergency service :
    99 (because of pbx’s…I.e if you are at the office and dial 999, forgetting to dial 9 for an outside line, you will still connect to the emergency services) So 99 works on all phones
    911 because we are all so used to American films and TV
    112 anywhere in the European union

  3. I recently discovered anyone can follow a twitter account by SMS (whether you have an account yourself or not) just by texting ‘follow’ and then the account name to the twitter service number in your country (40404 in the US, 86444 in the UK). Bound to be useful for getting news and updates, as long as you know in advance what accounts may be useful to you. I’ve made a list 🙂
