Which is a better? GPRS SIM800L or GPRS SIM900? I will implementate the GPRS technologity in my Arduino project, but before buy the module, I want to know which is a better. If GPRS SIM800L or GPRS SIM900? My needs are send JSON array through POST request.

Thanks and best regards.
SIM900 is older type. SIM800L has FM build it and it uses same AT cmds as SIM900.
Also, they are in same quadband. I guess both will work just fine.
