The SIM800L module is a quad-band GSM / GPRS device, working on the frequencies GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz.
This mobile phone module allows you to add voice, text, data and SMS to your project in a small module.
This version has a uFL connector.
It uses the same SIM800L chip as the FONA module of Adafruit, so the same libraries can be used.
