You can use the radioOff() function, which uses AT+CFUN=0 to put the module in reduced functionality or the powerOff() function which uses AT+CPOWD=1 to power it down. To use powerOff() you need to have connection to the PWRKEY pin to turn it back on. The SIM800 hardware integration guide has a log of information about the various power modes.
Hi,
Is there a way to put the SIM800L into a low power sleep mode?
