Raymann, you are wrong.
There is no settlement between wireless companies for (local to local) calls. This same non-settlement scenario prevails more and more for wireline calls too.
Access charges do remain for the receiving company on any scenario where a long distance call is delivered to the local company, either wireless or wireline. And in this scenario, ATT attempts to cheat on their payments across the board.
You could be right, I haven't read up on that in a while.
No he isn't.
He is talking about roaming charges, although using Verizon and Cingular as examples won't work since they use different technologies. Inter-carrier roaming settlement charges amount to several tens of millions of dollars a day.
I'm not sure what you mean about AT&T "cheating" on their long distance access payments. Wireless-to-wireline long distance is handled on a wholesale basis. I don't know of any wireless company that charges its customers long distance any more.
