About this product
The SIM800A is a dual-band GSM/GPRS module working on the EGSM 900 and DCS 1800 MHz bands, with support for voice, SMS, and GPRS data. It is driven by AT commands over a serial interface and needs a 3.4 to 4.4 V supply able to deliver transmit-current pulses. Availability of 2G service on the target network should be confirmed before deployment.
