More Details
The first three digits of the carrier code indicate the
country of operation. The last two digits are the carrier's allocated "color" within that country. For
example, in Australia, Vodafone is 505-03 (country 505, carrier color 3). In the UK, however, Vodafone is 234-15
(country 234, carrier color 15).
There are two main occasions when you might need to know a carrier code. The first is if you need to edit the roaming
(preferred carrier) database on your SIM card. Not all phones allow you to do this (Motorola is the only brand
I can immediately think of that offers the feature).
The second reason you might need to know a carrier code is because some unlock codes (e.g. SIM unblocking codes)
are algorithmically generated from the code of the carrier that issued your phone. Various cracking programs exist
to calculate these unlock codes if you type in (for example) the phone's IMEI and the issuing carrier code.

My third book is released! Learn what you'll need to know in order to become an embedded engineer.

Check out my second book; learn practical stuff about building robots and control systems around Linux PCs and the Atmel AVR.

My first book gives you all the intro you need on developing 32-bit embedded systems on a hobbyist budget.

GSM Carrier Codes
The list below has been compiled from the firmware of various GSM900,
900/1800 and 1900 handsets. It is not necessarily complete. Also note that the carrier description strings are
transcribed directly from the phone's display - any misspellings or unusual abbreviations in the handset manufacturer's
records have been accurately reproduced here.
