Specifications:

1.What is GSM module SIM800A?

• GSM module SIM800A is a cellular module that operates on the 2G (GSM/GPRS) network. It supports cellular network communication and includes features such as voice calls, SMS messaging, and data transfer. The module is intended to be integrated into a variety of applications, such as IoT devices, that require communication over a cellular network.

2.Does SIM800A support 4G SIM?

• No, the SIM800A is a 2G (GSM/GPRS) module and does not support 4G (LTE) network. It is designed to work with 2G SIM cards only. If you need a module that supports 4G, you may consider other cellular modules that support LTE network.

3.What voltage is SIM800A?

• The SIM800A module operates on a voltage range of 3.4V to 4.5V DC. It is recommended to use a regulated power supply to ensure stable voltage input and prevent damage to the module. The specific voltage requirements may vary depending on the operating mode and the specific application requirements. It is important to consult the datasheet for the module for more information on the voltage requirements and operating conditions.

4.What is the difference between sim800a and SIM900A?

• The SIM800A and SIM900A are both cellular modules that support 2G (GSM/GPRS) network, but there are some differences between them:
  • Frequency bands: The SIM800A supports 900 MHz and 1800 MHz frequency bands, while the SIM900A supports the 900 MHz frequency band only.
  • Package type: The SIM800A is available in a compact LGA form factor, while the SIM900A is available in a larger PCB form factor.
  • Power consumption: The SIM800A is designed to have lower power consumption compared to the SIM900A, making it more suitable for battery-powered applications.
  • Features: The SIM800A has more advanced features compared to the SIM900A, including TCP/IP stack, HTTP protocol support, and built-in MP3 decoder.
