SIM808 module is a complete Quad-Band GSM/GPRS module which combines GPS technology for satellite navigation.
The compact design which integrated GPRS and GPS in a SMT package will significantly save both time and costs for customers to develop GPS enabled applications. Featuring an industry-standard interface and GPS function, it allows variable assets to be tracked seamlessly at any location and anytime with signal coverage.


SIM808 GSM with GNSS module is a Quadband GSM, Gloneass GPS, Bluetooth three-in-one function module. Designed for the global market, SIM808 is integrated with a high-performance GSM/GPRS engine, a GPS engine, and a BT engine. The GSM/GPRS engine is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz. SIM808 GSM features GPRS multi-slot class 12/ class 10 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. The GPS solution offers best-in-class acquisition and tracking sensitivity, Time-To-First-Fix (TTFF) and accuracy
