DCS1800/PCS1900
DATA mode, GPRS ( 3 Rx, 2 Tx ) CLASS 10
GSM 850/EGSM 900
DCS1800/PCS1900
DATA mode, GPRS ( 4 Rx,1 Tx ) CLASS 8

Class 10 is default set when the module work at data translation mode, the module can also work
at class 8 set by AT command.

5.5 Electro-Static discharge

The GSM engine is not protected against Electrostatic Discharge (ESD) in general. Therefore, it is
subject to ESD handing precautions that typically apply to ESD sensitive components. Proper
ESD handing and packaging procedures must be applied throughout the processing, handing and
operation of any application using a SIM802 module.
The measured values of SIM802 are shown as the following table:
