Description SIM800L GPRS-GSM Module SIM800L GPRS-GSM Module support Hyper Text Transfer Protocol application. Which provides a mode to the alternate of HTTP server. The basic application contains GET, POST, HEAD methods; it also supports proxy server, redirection, broken transfer resuming functions. SIM800 series modules support File Transfer Protocol application. Which provides a mode to interact with FTP server. The basic application contains GET, PUT methods, it also supports broken transfer resuming function. PUT method supports APPE, STOR and other modes. Features: Power supply: voltage range: 3.4V`4.4V Power saving: SLEEP mode is 0.7mA (BS-PA-MFEMS=9). Band: GSM type: small mobile station four frequency: EGSM900, DCS1800, GSM850, PCS1900, can automatically search the four frequency bands. You can also set the frequency band through the AT command.
