Technology is wonderful when it works

When you send an SMS from your cellphone, the carrier company is making pure profit from you. The SMS travels in the carrier identifier signal that has to be present for a cellphone to talk to a cell tower. It costs the network nothing because without the signal, there's no cell network. ie. the presence of your cellphone on a tower means you can text and it costs nobody anything.
