I've been reading up on a way to send simple encrypted SMS without a mobile phone data plan. I don't know how well it can work over long distances, but it seems to act like a network of repeaters. Anybody using this system? I'd like to find out more. I have family in Vidalia, Portland Or. and NSW Australia. Not sure if it can be used for such long distances. But it really only depends on the development of the "mesh" network, it seems. No Ham radio license needed. And the only equipment may be just a simple $30 radio signal emitter.
