Hi I've got a problem, Im using a Mega2560 and it s not working.
Does anyone knows how to solve this problem.
I'm testing the code below , but the problem is the pin, cause I've read somewhere that i can not use the pin D0 to d9 as serial. And I don t know how to solve it.

if(cell.available() >0)
{
incoming_char=cell.read(); //Get the character from the cellular serial port.
Serial.print(incoming_char); //Print the incoming character to the terminal.
}
//If a character is coming from the terminal to the Arduino...
if(Serial.available() >0)
{
incoming_char=Serial.read(); //Get the character coming from the terminal
cell.print(incoming_char); //Send the character to the cellular module.
