Does cell.begin(9600) can make a issue if the Euripean bamn is 1800?

Could you calrifie the imprtamce of this?

Code:

  //Initialize serial ports for communication.
  Serial.begin(4800);
  cell.begin(9600);

These values refer to the baud rate (bits per second) of the serial port modules, i.e. the rate of communication from your arduino chip to your GSM shield (assuming that's what you're doing with "cell") and your pc ("Serial"). It is not related to your locality or provider, only the way your arduino chip connects to the shield.
