+/*
+ * This example shows how to send an SMS message using the Arduino_Cellular library.
+ * 
+ * Instructions:
+ * 1. Insert a SIM card with or without PIN code in the Arduino Pro 4G Module.
+ * 2. Provide sufficient power to the Arduino Pro 4G Module. Ideally, use a 5V power supply
+ *    with a current rating of at least 2A and connect it to the VIN and GND pins.
+ * 3. Make sure the SIM card has enough credit to send SMS messages.
+ * 4. Specify the APN, GPRS username, and GPRS password of your mobile network provider.
+ * 5. Specify the PIN code of your SIM card if it has one.
+ * 6. Specify the phone number of the recipient and the message you want to send. 
+ * 7. Upload the sketch to the connected Arduino board.
+ *
