send SMS in Series 60

Hi
Please take a look at the code I try in order to send a sms message (for now there is no text in it ).

in the emulator the execute goes without errors and with a system info message the the mms message was sent ,
In the Nokia 6600 there is no error , but also no info message , and no sms is sent (at least not to the number I wrote , which is a regular mobile ).

*** what do I do wrong ?

*** also , how can I add a simple text or header to the message , like for example "Start Message"?

Thanks in advance , TE
