How to send SMS to handphone using N30 with AT Command?
Which AT command is necessary?

And who can give me a detailed sample?

I use the +CMGS command:

at+cmgs="+13807885670"
> 888 ->
+CMS ERROR: 500

who can tell me what mean about "ERROR: 500" ?

Hi,

Do you have sms-center number set?
The error 500 arise at least when the number is missing.
Anyway.

at+cmgs="<phone number>" <enter>
message <ctrl +z>

should work, at least it worked for me when I tested it.
