Hi,

Can I connect to Sony Ericson K810i phone directly to the PIC16F877 like show in the schematic ??
Then I need to send sms by executing AT commands. 621-cpw3 (1).jpg
 

Assuming that the said PIC16F877A supports RS 232,I think it can be done,the way you have shown the connections in the circuit diagram...It is worth a try.But what will you use it for?
What are some applications,that you can think of,will be using this arrangement system..?
Try to make the connections and test the system,and let me know what happens..

Well can you please tell me the advantage of usinga phone over a GSM module for SMS alarm system?

the advantage of the GSM modem is the small footprint - the aerial tends to be larger than the modem these days!
if it has a TCP/IP stack one can send UDP datagrams, connect to TCP servers (e.g. use FTP to download and upload files), etc etc
add GPS and you can determine location

I asked why OP preferes Phone ? what are the advantages he is going to get if a Phone is used?

I know the advantages of Modules. But some times some modules give problems.
