difference between Binary header and //SCKL header

[heekeon]

Hi-

I tried to send ringtone data through JAVAMail API or OutlookExpress.
And I still have failed to send it. However, I can upload same ringtone through my operator free SMS sending center. My operator is Rogers AT&T in Canada.

And I realized that Nokia recommend to use Binary Header rather than SCKL Header.

My question is:
(1) Can I use binary header even in OutlookExpress or JavaMail?
I tried, but I don't know how.
(2) So does Binary header imply to use PUD mode with AT modem?

Thanks a lot in advance!

1)I don't think that you can use mail to deliver smart messages.
2)It is easiest to use data shown as hex when dealing with binary
data. In PDU-mode data is always shown as hex, but also Text-mode
has user-data shown as hex when 8 or 16-bit data-coding scheme is
used.
In PDU-mode you can see the whole SMS as it is delivered in the
GSM-network. Both AT-command modes can be used to make
smart messages.
