why call ready sim300

Hello,

I have a sim300C and I'd like to connect to GPRS.

I used the hyperterminal to send at command.

I'm not able to connect to gprs
I used several command such as

at+cgreg?
+CGREG: 0,0

at+creg?
+CREG: 0,0

I think this two command specify that I'm not connect into the gprs

but when I used my simcard in my mobile phone I can connect to gprs.

could you please help, on how can I connect to GPRS

Best regards

I'm able to create file for example myfile.txt using the ftp commmand APPE myfile.txt
but when I send data using at+cipsend, I don't find the data sent in the file myfile.txt

Could you please tell me how can I send data within file.

Thank you for your help
 

Hi,

I am using SIM300_V7.03 module for FTP connection. I want to do FTP connection and then create one text file in FTP server and then wants to send the data to that file. So please let me know whether it is possible in this module. If yes then please let me know the procedure.

Hello,
Can you please shrare the command sequence used to create a file. Please suggest a free FTP server for testing purpose, where a file can be upload/download is possible.
