Aplus messenger? Gsm Receiver?

is there any hardware(not another GSM modem) out there that can recieve sms from a GSM modem and then power up LED Lights and stuff, in another words with outputs on it?

if u dun get what i meant, what im looking for is something similar like a Aplus messenger but wondering if theres other cheaper hardware around that has the same function.

hope you guys could link me up, greatly appreciated.

thanks in advance.
