Identifies the telephone number to send an SMS message to.
SMS.beginSMS(number)
number : char array, the phone number to send the SMS to
int In asynchronous mode, beginSMS() returns 0 if the last command is still executing, 1 if success, and >1 if there is an error. In synchronous mode, it returns 1 if it successfully executes, and 0 if it does not.
