Hi Aratti, thanks for replying...
I suggest you to use a devider also for the PWON input.
do you mean to place another 3k3 to PWON and Gnd? Do you think if I use 3.3v to PIC16F628A will communicate well to the GSM module? I tried to supply the mcu with 3.3v with blinking program on PortB.0 but using the voltage meter no deflection shown.
Please help.....

regards,
joe
