Unfortunately, this error message means that your carrier's SMS center does not currently support 7-bit BinHex file deliveries. We suggest that you ask your carrier to upgrade the service so that you can receive binary files like ring tones.
Alternatively, if you know a friend whose phone you can send ring tones or logos to, put his or her GSM (PCS) chip in your phone, send the media you want to his or her telephone number (using your phone), save the ring tone, and then swap your GSM chip back into your phone. The phone itself will retain the ring tone.
