Introduction:

In this tutorial, we’ll learn how to connect an Arduino Uno to a 4G LTE module to send SMS messages and make calls. We’ll be using a Jio SIM card, but you can use a SIM card of any generation (2G, 3G, or 4G). This tutorial will guide you through the step-by-step process of uploading code and controlling messages and calls.

Hardware Required:

1. Arduino Uno board
2. 4G LTE module
3. Any SIM card(2G,3G,4G)
4. USB cable
5. Smartphone (optional, for receiving messages and calls)
6. Jumper Wire

Software Required:

1. Arduino IDE

Step 1: Hardware Connection:

1. Connect the Arduino Uno to the computer via USB cable.
2. Connect the 4G LTE module to the Arduino Uno according to the pinout.
3. Insert the Jio SIM card into the 4G LTE module.

Step 2: Uploading Code in Arduino IDE:

1. Open the Arduino IDE.
2. Open the example code provided or paste the code given below.
3. Select the appropriate board and port, and upload the code to the Arduino Uno.

Step 3: Sending Messages:

1. Open the Serial Monitor.
2. Type “S” and press Enter.
3. A message will be received on the smartphone.

Step 4: Making Calls:

1. Open the Serial Monitor.
2. Type “C” and press Enter.
3. A call will be received on the smartphone.

This way, you can use the 4G LTE module with Arduino Uno to send messages and make calls.
