SIM300 design help

Hi All,

I am developing a remote monitoring system using SIM300 module. My requirement is to communicate to SIM300 using 3 pin configuration i.e. TXD,RXD and GND.
For this purpose I am designing circuit keeping SIM300_EVB schematic as base. I have made certain modifications to it in order to meet my requirements. Please take a look at the attached schematic and suggest any changes if required.
Any help will be greatly appreciated.

Thanks,
Pagal
