An honest in-flight announcement

Wed, 13 Sep 2006 12:00:00 +0000

What would an honest in-flight announcement sound like? Among other things, it would say…

Please switch off all mobile phones, since they can interfere with the aircraft’s navigation systems. At least, that’s what you’ve always been told. The real reason to switch them off is because they interfere with mobile networks on the ground, but somehow that doesn’t sound quite so good.

Mobiles can be used on flights

Mon, 12 Apr 2004 12:00:00 +0000

Phones can be used on flights. (from The Economist. Requires subscription)

On an average transatlantic flight, several phones are usually left switched on by accident, and the avionics systems on modern aircraft are hardened against radio interference. No, the use of phones on planes is banned because they disrupt mobile networks on the ground. An airliner with 500 phones on board, whizzing across a city, can befuddle a mobile network as the phones busily hop from one base-station to the next.

Check your mobile phones serial number

Thu, 21 Jun 2001 12:00:00 +0000

A note from my friend Ashish: “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. Should 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. If everybody did this, there would be no point in stealing mobile phones.”

silverfaewolf 14 Jan 2009 10:12 pm: The code works for certain providers. However, you can also go into your phone settings, and find “phone information” or something similar, and it will also give you the equipment serial number (ESN). Phones w/an IMEI, that’s the same as an MSN or ESN (manufacturer’s or Equipment). It depends on the network. Sprint, Verizon, Cricket, and Metro PCS all run on CDMA towers. Nextel runs on iDEN towers. T-mobile and AT&T run on unicel. Unicel towers are the most common worldwide, but CDMA are the most common in the US. This is why you can use a japanese at&t phone in the states, but can’t always transfer it to the sprint network. They’re designed and programmed to run on different towers.
Waqas 18 Apr 2009 8:41 am: Hi. This trick is useless because if you’ve got a stolen mobile and its IMEI number is blocked by the service provider, there is still a way to use this handset. Reinstall the software of the handset and change the IMEI number too:)). In some countries, the person who does this job would ask the 50% amount of the handset for doing this job.
