This is a mini SIM800L GPRS GSM module, micro SIM card core board, quad-band TTL serial port with an antenna. This module consists of antennas.
The SIM800L GSM/GPRS module is a miniature GSM modem that can be integrated into various IoT projects. This module lets you do almost everything a normal mobile phone can do. You can send text messages via SMS, make and receive phone calls, and connect to the Internet via GPRS, TCP/IP, and more. Additionally, the module supports quad-band GSM/GPRS networks, allowing it to work virtually anywhere in the world.
The first is a wire (soldered directly to the NET pin on the board), which is very useful in tight spaces. Second – PCB Antenna – Comes with double-sided tape and pigtail cable with IPX connector. This improves performance and allows the module to fit in a metal case as long as the antenna is outside.
