SIM800 modules are upgraded version of its previous successful GSM/GPRS/GPRS module series SIM900. There are multiple sub versions of each series, each of which cater to a different set of users and applications.
SIM800 vs SIM900 GSM modules
There exist multiple versions of these modules,
SIM900 comes in the form of full version Quad band SIM900 & dual band version SIM900A, SIM900D
SIM800 comes in the form of full version Quad band SIM800 & stripped down compact size version SIM800C.
"What extra does SIM800 modules give me compared to SIM900 series modules?"
SIM800 GSM modules have a inbuilt Bluetooth stack compliant with 3.0+EDR & FM radio support, and the interface is accessible using AT commands.
