As long as the system isn't being moved and not sending you a message then it won't use the credits. So what is the issue here? get yourself a cheap prepaid phone and put $40 on it and you should be set for quite a while.

it's not that easy! in my country, even if you dont use credit, they go away after a couple of days (7 days mostly), they do this to make people buy credit and use them!

Well unless you stay withing about 12 meters of the device you don't really have another decent option.

I thought of a Transmitter/Receiver, but it has to got a big range !

That sort of thing tends to be regulated by government requiring licenses and whatnot to use. So like i said anything that broadcasts beyond around 12 meters isn't going to be much of an option. Which is why the most affordable option is sms with a cell phone. Even if your country has no regulations to help prevent companies from ripping you off.
