We have shared the full setup of the GSM shield box here and free download links are available for download. To configure a GSM Shield Box for Windows, you will first need a SIM card from your chosen carrier. A SIM card is a contract between you and a communications provider.
You will also need a USB cable, which you can purchase from a cell phone retailer. To use the device, you must first power it on by pressing the power key for two seconds.
Then, the LED will blink once every 800 ms until it finds a network. If the LED stops blinking after three seconds, you can turn the device on using the software that comes with the device.

GPRS is a packet-switching technology
GPRS stands for General Packet Radio Service. It is a best-effort telecommunications protocol that is used for wireless network communication.
Unlike GSM, which only provides 9.6 Kbps of data transmission and supports 160 characters per message, GPRS allows for much higher data rates.
GPRS allows for faster wireless mobile Web browsing, instant messaging, and chat services, as well as home automation via wireless remote control.
GPRS can increase data rates to 56Kbps and 114Kbps, depending on the type of device and the network. GPRS is also more convenient for interactive communication, like video conferencing. Users can connect to VRN without dialing up.
This mode of communication changed the fundamentals of communication and has become critical in areas where wireless resources are scarce. GPRS is a packet switching technology that enables mobile internet connections to be faster than ever.
A SIM card is a contract with a communications provider
A SIM card is a small, removable electronic device that has a contract with a communications provider. In the first years of their introduction, SIM cards were the size of a credit or bank card, but they have since shrunk in size. They are still electrically identical, though, and can be transferred from one device to another.
In recent years, eSIM has replaced the physical SIM card in some domains. eSIM uses a software-based SIM embedded into an unremovable eUICC.
OneSimCard accepts returned SIM cards for credit and does not have any liability for their customers or for any third party’s failure. This includes faulty equipment or improper installation.
In addition, OneSimCard has no responsibility for the quality of service or for any malfunction of the device. Additionally, the SIM card is the Customer’s sole responsibility. The contract will survive the termination of the Agreement.
GPRS library functions
Using the GPRS library functions of GSM Shiard Box Setup for Windows is as easy as pressing one button and then pressing another. The shield can be powered by an external 5V power supply, which is available on the PC.
To turn it on, press the power key for two seconds. The shield’s LED will blink every 800 ms until it finds a network. Once it does, it will blink every three seconds. Then, you can turn it off and on via the software.
Once you’ve done that, you can send AT commands to make phone calls using the SIM900. Then, restart the SIM900 and enter the target number. It is important to enter the number without quotes to make it work. The result will be an “ATH OK” message. Occasionally, this will fail if the number you enter is unintelligible or the command format is incorrect.
When you’re using a PC with an Ethernet port, you can use the GSM Shield Box Setup For Windows application to configure the box and send and receive SMS texts. The GUI of this application contains AT commands to change the baud rate of the shield, which you can change from 115200 to 19200. By following these instructions, you can quickly and easily set up your shield with Windows.
During GSM Shield Box Setup For Windows, you can send and receive AT commands directly from your PC. Before coding the AT commands, make sure you send them in the correct sequence.
Model: GSM Shield Box
Current Version: 2.1.2

This software also has a utility for decoding the AT commands. Once you know the sequence of the commands, you can easily implement them into your application. If you’re using a sketch or library, you can implement AT commands in your code.
Powering up the GSM Shield
There are two ways to power up the GSM shield box for Windows. The first method is to plug in a standard USB power supply. The USB power supply must have at least 5V. The second method is to use a DC jack to power the Arduino shield. The Arduino shield has a toggle switch next to the DC jack that you can use to power the shield. Press the power key for two seconds to turn it on. The LED on the shield will blink every 800 ms until it finds a network. Once it does, it will be ready for use.
To start using the GSM shield, you need an Arduino or Raspberry Pi board and a SIM card. The SIM card represents your contract with your communications provider. Your SIM card should support GSM coverage in your area, or have a roaming agreement with a GSM carrier. You will need to purchase the recommended accessories separately. To power up the GSM shield for Windows, use a 2G or 3G Mini SIM card.
Using the UART port
If you are using Windows, you should use the UART port on your computer for the GSM shield. You can use the command ‘at’ to change the baud rate of the shield. By default, the shield runs at 115200, but you can change it to 19200 by using the AT command. Once you have changed the baud rate, you should see a small LED on the shield.
To enable the GPRS shield, you should first enable the SIM card and then install the required libraries. You can also use the SoftSerial Library for this purpose. This will allow you to communicate with the GSM shield box. The SoftSerial Library and DialVoiceCall() libraries are required to send and receive messages. The following lines are included in the software.
