Frequently Asked Questions

1. What is the SIM800L GPRS GSM module?

  • SIM800L GSM/GPRS module is a small GSM modem that can be integrated into a variety of IoT projects. You can use this module to do almost anything a regular cell phone can, such as send SMS text messages, make or receive phone calls, connect to the internet via GPRS, TCP/IP, and more.

2. Can SIM800L connect to internet?

  • SIM800L supports General Packet Radio Service (GPRS) for internet access via HTTP. The module includes a TCP/IP stack that can be accessed using AT commands. This is particularly useful for persistent data logging on low bandwidth networks.

3. Does SIM800L support 4G SIM?

  • SIM800L only supports 2G services. If it is not getting network, try another 2G card and connect the GSM antenna. I use Airtel 4G SIM cards as well as Vodafone 4G sim cards. They operate normally on a 2G network.

4. How do I know if SIM800L is working?

  • If the SIM800L receives enough power, the onboard LED begins to blink. If it is blinking every second, it is looking for a network. It will blink every three seconds if it is connected to the network. If the LED blinks rapidly, it indicates that it is connected via GPRS.

5. How does GSM module work?

  • A customized Global System for Mobile communication (GSM) module is designed for wireless radiation monitoring through Short Messaging Service (SMS). This module can receive serial data from radiation monitoring devices such as survey meters or area monitors and send it to a host server as text SMS.
