text: how to send a ringtone composed by me from pc to mobile? i composed a ring tone using ringtone convertor. now i want to send it to my mobile.  but when i tried to sms the ring tone it was received just as an ordinary sms.  need help the key to this problem depends much on the type of your mobile phone. a 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).  an ems is basically an sms (160 bytes at most, usually) that embodies simple black-and-white images or ringtones. in mms-es you can attach one or more images or ringtones (midi or wav) to a text message. if 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).
