Hello all,

I have done the connection between the remote server and the client where the SIM300 modem is connected through TCP/IP stack.

But now i have to establish the email facility.
but i am not able to do so.

So please can anybody tell me am i using the right modem (SIMCOM SIM300)??
Does this modem have a facility to send and recieve the emails??

If yes then please send me some procedural steps for the same, and if not then which modem should i have to go for the same application??

Please reply me as soon as possible...

Thanks in advance...

Added after 3 minutes:

Is there any setting needed for the SMTP??

I didn't find any kind of AT commands for the setting of SMTP??
Even i couldn't find anything regarding the SMTP for mailing in the SIM300 modem...

Please help me...[/QUOTE]
