SIM800L V2.0 5V Wireless GSM GPRS MODULE Quad-Band MOD31

SIM800L V2.0 5V Wireless GSM GPRS MODULE Quad-Band MOD31

The manual emphasizes the module’s command-driven design: it supports the standard 3GPP AT command sets plus SIMCom proprietary extensions so that a host microcontroller or PC can manage network registration, calls, messaging and GPRS data sessions via textual AT sequences. The document describes command categories for voice/SMS/GPRS/TCP-IP/HTTP/FTP/MMS and many service functions, showing that the SIM800L is designed to be operated and scripted entirely through these well-documented commands.

Engineering detail in the manual highlights per-variant differences (the SIM800L is one of several SIM800 family variants), noting specific supported commands and hardware signals (for example jamming-detection pin and ADC support differences). The manual positions the SIM800L as a flexible embedded communications engine whose behaviour and services are exposed at the AT level making it suitable wherever a compact, commendable GSM/GPRS engine is needed in a larger device.
