check AT+CSQ?
see output is not 99,99
it can be any value but not 99
if it is 99 then there is no signal received by modem....
what antenna are you using for modem

Dear Thanh
This is Danielle form SIMCom,please tell me where you bought the modules?
What is your project?
Thanks for details
Dear Mr. LTK1827,
i have seen your At command code above, you are not giving correct AT command for ATD.
please try ATD975905660; in this format.
you are not giving semicolon after the mobile number, plesase try & do let us know whether it solved your issue or not.

i tried lots ATD command. But now problem is NODIALTONE. I check CSQ Command still has signal = ~(25,0), (30,0)
And if i flash new FW name SIM300M32 down from this forum to my module SIM300S32. CSQ command result alway = (99,99)
reflash the firmware and try....... I hope your SIM is not having security password
