[SOLVED] AT command for refilling prepaid account.

[luatntother]

I'm developing a system which use Sim300cz module, is there any AT command for refilling sim card's prepaid account? Thank you very much for your helps!
Best regard

P/s: In my country, i can refill my prepaid account by typing *100*xxxxxxxxxxxxx# then pressing call button on my phone where xxxxxxxxxxxxx is code of a operator's card.

I presume that the *100* "call" is transmitted as "Unstructured Supplementary Service Data", see +CUSD command.

+CUSD is also used to request the acount balance of prepaid cards with a "*100#" (or similar) command.
