I still don't get where you're going with this. A telecoms company provides a service, probably best described as a telecoms service, since that is the market sector they have chosen to operate in.

And I give them some money so they can pay their doodz and invent better phones & stuff.

And after a while someone invents something ruthlessly better than phones, like telepathy or something, and we all say 'these phones are now officially teh suck' and bin them and use whatever the new thing is. Like what happened to tyewriters.

Yes?
