What is GSM module SIM800?

SIM800 is a quad-band GSM/GPRS module that works on frequencies 850MHz GSM, 900MHz EGSM, 1800MHz DCS, and 1900MHz PCS.It also features GPRS multi-slot class 12/class 10 (optional), and supports CS-1, CS-2, CS-3, and CS-4 GPRS coding schemes. It has one UART port.

How to connect SIM800 to Arduino?

Wiring – Connecting SIM800L GSM module to Arduino UNO Start by soldering/connecting the antenna, insert fully activated Micro SIM card in the socket. Now, connect Tx pin on module to digital pin#3 on Arduino as we’ll be using software serial to talk to the module.

What is SIM800?

SIM800 is a complete Quad-band GSM/GPRS solution in a SMT type which can be embedded in the customer applications. SIM800 support Quad-band 850/900/1800/1900MHz, it can transmit Voice, SMS and data information with low power consumption.

What is difference between SIM800 and SIM900?

SIM800 is the newly released alternate to SIM900 having the same functionality as SIM900 with additional Bluetooth/FM support. Hardware Differences : Voltage range : SIM900 supply voltage ranges from 3.2V to 4.8V whereas SIM800 has reduced supply voltage range of 3.4V to 4.4V.

How do I know if SIM800L is working?

If the power to the SIM800L is enough, the on-board LED starts blinking. If it is blinking every second, this means it is searching for a network. You will know if it’s connected to the network when it blinks every three seconds. If the LED blinks very fast, this means it’s connected through GPRS.

Can we use 4G SIM in SIM800?

Does the SIM800 use a 4G SIM? – Quora. The SIM800 is a GSM/GPRS-only modem module. It can use either a 2G-only SIM or a 3G/4G USIM (which provides compatibility for 2G anyway). It will only work on 2G GSM radio networks so you have to check that in your country – for example it won’t work on the AT or Jio networks.

Does GSM module need SIM card?

A GSM module is a tiny cellphone. It needs a sim card, the same as any other phone. If you want to send a message between two GSM phones, both need to have active sim cards.

How do I connect SIM800 to Raspberry Pi?

Theory, how to use a SIM800L with a Raspberry Pi?

  1. Connect the SIM800L VDD to a GPIO providing power on the Raspberry.
  2. Connect the SIM800L GND to a GND GPIO on the Raspberry.
  3. Link the SIM800L TXD to the Raspberry RXD.
  4. Link the Raspberry’s RXD to the SIM800L TXD.
  5. Send and receive data with AT commands on the serial port.
