text: The key to this problem depends much on the type of your mobile phone.\nA plain SMS is just a text message. To attach something to a message, you need to send an EMS (E for Extended) or a multimedia message (MMS). \nAn EMS is basically an SMS (160 bytes at most, usually) that embodies simple black-and-white images or ringtones.\nIn MMS-es you can attach one or more images or ringtones (MIDI or WAV) to a text message.\nIf the phone model allows it, you can purchase a USB data cable to transfer data to/from the PC, or you can use wireless technologies, including IrDA and Bluetooth (the PC must be equipped with an appropriate adapter).
