Mobile Phone
Hacks !
First off, let me introduce you my Phone:
In the true spirit of hacking, here are some things you can do with your 'mobile' phone.
Send SMS via serial port
Your mobile phone has a GSM modem inside. You can communicate with this modem as other modems (AT Commands).
Sending an SMS text message to a mobile phone from a terminal device is pretty simple. The phone used in this example is a Samsung C100, which is linked to the computer via Infrared which uses communications port #4.Note that the Ctrl-Z is necessary for terminating the text entry.
To send an SMS text message to a Nokia phone with Visual Basic:
' Set up the communications port MSComm1.CommPort = 4 ' Com Port 4 ' Set for 9600 baud, no parity, 8 data, and 1 stop bit. MSComm1.Settings = "9600,N,8,1" ' Tell the control to read entire buffer when Input is used MSComm1.InputLen = 0 ' Open the port MSComm1.PortOpen = True ' Send an 'AT' command to the phone MSComm1.Output = "AT" & Chr$(13) & Chr(10) ' The phone will respond with an 'OK' ' Set up the phone for a text message MSComm1.Output = "AT+CMGF=1" & Chr$(13) & Chr(10) ' The phone will respond with an 'OK' ' Prep for SMS, give destination type and destination address. ' Enter the destination type and destination address to prep for SMS ' e.g. AT+CMGS="9841274555",129 MSComm1.Output = "AT+CMGS= " & Chr(34) & _ "9841274555" & Chr(34) & ",129" & Chr$(13) & Chr(10) ' The phone will return a'>' prompt, and await entry of the SMS message text. ' Now send the text to the phone and terminate with (Ctrl-Z) MSComm1.Output = "Hello World !!!" ' The phone will respond with a conformation containing ' the 'message reference number' eg. +CMGS:' Close the port MSComm1.PortOpen = False
I would like to send SMS using the 8051 micro. But I don't have the serial cable yet.

I use EasyGPRS and the IrDA port to download RingTones to my phone.
IMEI Number - The Unique number for your phone
The IMEI (International Mobile Equipment Identity) is a unique 15-digit code used to identify an individual GSM mobile telephone to a GSM network. The IMEI can be displayed on most phones by dialling the code *# 06 #. It is also usually printed on the compliance plate under the battery. An IMEI code is divided into four sections, with each section separated by a space as shown by this example: 490520 30 123456 0. The table below describes the four items that combine to make the IMEI number.
| Item | Description | Example |
| TAC | Type Approval Code - The first six digits of the IMEI. This code identifies the country in which type approval was sought for the phone, and the approval number. The first two digits of the TAC represent the country of approval. | 490520 |
| FAC | Final Assembly Code - Identifies the facility where the phone was assembled. Eg Nokia, Alcatel etc | 20 |
| SNR | Serial Number - The unique serial number of the handset | 123456 |
| SP | Spare - Usually this digit is 0 | 0 |
IMEI numbers of cellular phones connected to a GSM network are stored in a database (EIR - Equipment Identity Register) containing all valid mobile phone equipment.
When a phone is reported stolen or is not type approved, the number is marked invalid.
When a phone is switched on, this unqiue IMEI number is transmitted and checked against a database of blacklisted or greylisted phones in the network's EIR (Equipment ID Register). This EIR determines whether the phone can log onto the network to make and receive calls.
Though it is illegal, there are ways to change this number ;) But why? Think about that for yourself. But How. GOOGLE it.
