Connection and code for controlling sim800l , arduino and 8 channel relay

PLEASE, AS A MATTER OF URGENT CONNECTION AND CODE FOR CONTROLLING SIM800L , ARDUINO AND 8 CHANNEL RELAY

After the connections using sim module, arduino and relay, am having major problem with the coding. When I send a message to the Sim module, the bulb won't light on despite confirming that the sim module have established network connection with the Sim successfully.

Please, I'll need help with the text code for connecting arduino, a sim module and a channel relay.

Thanks
