Send an SMS message to a phone
The XBee Smart Modem can send and receive Short Message Service (SMS) transmissions (text
messages) while in Transparent mode. This allows you to send and receive text messages to and from
an SMS capable device such as a mobile phone.
Note For help with debugging, see Debugging.
The following table explains the AT commands that you use in this example.
