Figure in the listing shows the pinout of GSMsim800 for testing follow the given steps:

• 12v supply is given to the DC jack.

• Inset the simcard.

• Then push switch to ON.

• Then power LED is ON , as well as buzzer is ON.

• There is another two LEDs will on , One is for network selection(Yellow) and

• Another for range selection(Green).range LED blinks fast that means range is selected.

• Make connection with PC through TTL .

• Open hyperterminal and check through commands.

• When make a call for that no , buzzer is getting ON."
