Retrieving IMEI Information From A GSM Device
There is a mandatory requirement by the standardization bodies, that mobile devices for public networks may be uniquely identified by the IMEI number for many addressing and retrieval purposes.
On many, if not most devices, the IMEI number can be retrieved by keying *#06#, or using the AT command ATD*#06#.
The IMEI number of a GSM device can be retrieved by sending the command AT+CGSN. For more information, refer to the 3GPP TS 27.007, Section 5.4 /2/ standards document.

Famous quotes containing the words information and/or device:
“Phenomenal nature shadows him wherever he goes. Clouds in the staring sky transmit to one another, by means of slow signs, incredibly detailed information regarding him. His inmost thoughts are discussed at nightfall, in manual alphabet, by darkly gesticulating trees. Pebbles or stains or sunflecks form patterns representing in some awful way messages which he must intercept. Everything is a cipher and of everything he is the theme.”
—Vladimir Nabokov (1899–1977)
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
