ring tone prob. with smpp

Hi Stipe,

When I am sending ringtones with CIMD SMSC it comes to the mobile.

lynx --dump "http://127.0.0.1:12013/cgi-bin/sendsms?username=foo&password=bar&from=1234&to=123456789&udh=%06%05%04%15%81%00%00&text=%02%4A%3A%71%11%A5%B1%0D%A1%85%A1%D1%85%21%85%A4%04%00%66%98%C3%31%36%C5%12%89%44%97%89%76%16%61%94%17%81%68%14%62%4C%B0%DB%14%4A%25%12%5E%25%D8%59%86%50%5E%A5%AA%51%89%32%C3%6C%51%28%94%69%26%14%61%76%1B%61%94%17%61%64%12%41%44%92%61%46%17%89%B6%19%41%76%16%41%24%14%88%00"


but when I am sending through SMPP SMSC it doesn't come to the mobile.
Is there any limitation with SMPP SMSC.
The logo works well with both SMPP and CIMD.
