Camola, modem connection should not be crossed (I don't know with nokia) but try, if it doesn't work invert Rx with Tx at the phone cable.

Before to connect the max232 to the phone, make sure that is a standard RS232. If the phone has a 3.3 volts system you will blowup the phone communication line. In this case you should use a different approch.

Remember that if you connect the max232 to the PC serial port then Rx and Tx should be crossed. The connection given in the schematic are for a PC serial connection.

Have you tried connecting to a PC with a terminal program like the one in Micro Code Studio?

Camola, I am a little confuse. I did a bit of research on google and it seems that
nokia 6210 has a USB connection. Are you sure your phone has a serial connection?
