Hi i am trying to make a handphone call via arduino mega 1280. With the command below i am able to make the phone show "Callling 96631890" then "connecting 96631890" but it will not reach 96631890 nor ring . I checked the call list but 96631890 don't appear . Anyone know what could i add to make the call sucessful ?
void setup()
{
Serial1.begin(9600);
delay(25000);
}
void loop()
{
Serial1.println("ATD96631890");
delay(5000);
do
{
delay(1);
} while (1>0);
}
Wow, the AT command set, really testing my memory, so i might be wrong. Do you have touch tone service? I think ATD dials with pulse dial, while "ATDT" dfoes a touch tone dial...

I tried ATDT and ATD, both can't dial the cellphone number but i am able to dial my Landline House phone number sucessfully with both ATDT and ATD!!!
werid anyone know how to dial the Cellphone number successfully ?

I'd recheck the cell phone number and make sure you are using all the required numbers.

Well i believe i am using the correct number for dialling, Because i saved the number I.E apple as 96631890 , as i execute the ATD command, the phone show "Calling Apple" "Connecting Apple" but cut off immediately after that. If i change the number to my house phone number (Landline), it works !! but i need to work with another cellphone!!!
Anyone know what's the problem ?
Anyone know the reason why i cannot dial to cellphone ? Cannot find the information anywhere 
What hardware is doing the dialing?

Presumably you can dial the number manually ok?

Yes i am able to dial manually. Anyway i also found one thing werid is that although i can dial my house number sucessfully but when i pick it up, i can't hear anything nor the other user can hear me talking.
It is a few years since I did this, but I recall that the mobile I was using used an extension of the basic AT command set in order to set up and tear down calls. Have you tried connecting your handset to a PC and just controlling it manually using hyperterminal or similar? Probably easier than trying to figure out how it works using a sketch.
try this atdXXXXXXX;
or atd[][;]
XXXX is phone number
