That's sort of what I thought, AT&T will consider it simply a domestic call. I'm not concerned about the T-Mobile bill since it's part of the gift package that's sending her Down Under. :-) Under normal circumstances I'd get a local SIM and I appreciate the information about getting one in Australia.

I bought the small spool of quad wire at Radio Shack. I don't recall that they sold anything else for inside walls. They sold flat wire for the patch cord between the telephone set and jack, too. I don't recall seeing Cat3 at consumer electronics stores or home improvement stores ever. Was this a mass market consumer item in the days before Cat5 became somewhat common? I do recall seeing Cat5 at Home Depot and Builders Square when big box home improvement stores were new but I don't recall that they offered a choice of Cat3 or Cat5. I assume I'd have had to buy from Graybar if I wanted Cat3, and I might not have been able to buy a reasonably small quantity! One useful purchase I made was Cat5 patchcord with factory-installed plugs for RJ-11 jacks that I could use for the modem. That eliminated some interference.

After >all, in the quanties they consumed, that would have driven down the per unit >cost right off. 'wire' (in rational quantities) was not a 'billable' line-item, even on a T&M-based residential install. I don't recall if they even billed for the -jack- itself, the "labor" rate of circa $70/hr ($17 per 15min increment, circa 1972) put the materials 'in the noise' as far as the customer was concerned. However, going from 'pennies' per foot (quad) to 'several tens of cents' per foot (Cat 3) plus requiring 'home run' wiring rather than daisy-chaining from the nearest jack would have increased material cost *tremendously*. To the point it likely would have called for line-item billing. Whereupon the customers would have been screaming about the 'cost' that was ridiculously higher than what the neighborhood hardware store charged. That the higher-priced stuff is 'better" simply "doesn't matter" when the 'cheap stuff' is "good enough" for the immediate need. A rationale of "you'll thank me in 20 years" (or even 10) doesn't cut it with most people. That aside, the 'killer' fact is that nobody saw the revolution coming. Computers, even 'home' computers, were expensive (comparable to a good used car) and hard to use. Only an uber-geek would consider having more than one, IF said geek could afford it. And a "network" was 'yet another' big chunk of change (*hundreds* of dollars per 'node') on top of the cost of the base equipment. Put 'expensive' wiring in -every- residence to support -that- kind of use? Even as of the early 1990s the reaction to that would have been "you've got to be kidding!!" Wiring for a network in the residence -only- became an issue when the cost of 'a computer' had dropped to the point it was "reasonable" for _each_person_ in a household to have 'their own' unit, and 'networking' had dropped to the point that one "couldn't justify" the 'aggravation' of having to 'go to the computer room' to use a machine. Having adequate ground clearance for a 'mountain' is only an issue when the mountain -does- come to Mohammed, and not the converse. <grin>

Time to trot out a "reductio ad absurdum" argument... [BEGIN R-A-A] There have been documented cases of criminals, not in moving vehicles, using their mobile phones to dispatch hit-men to murder innocent victims who had no control over the cell phone user's actions. So I guess we will need to ban cell phone use by stationary callers as well as by those in vehicles. For that matter, there have been numerous cases of similar murder orders communicated by old-fashioned land-lines. So I guess non-mobile phones will also need to be banned. Anything to save a life, after all! [END R-A-A] The problem of all those "if it saves even one life..." type of arguments is that they rarely acknowledge that there might be costs along with the purported benefits. Those costs are not even purely financial, but may include opportunity costs in time and even in lives. A frequent example of unintended consequences is the field of aviation: new safety measures have to be carefully considered because if they raise the cost of flights too much, or add enough new travel delays, they will end up marginally increasing the number of people who choose to drive instead of fly, inadvertently causing more deaths on the road than they prevent in the air. So by all means, state the case for trying to ban all communication from phones moving at more than X miles per hour (for some value of X). But be prepared to quantify the costs as well as the benefits, so that we can weigh the tradeoffs. We are all aware of reports of crashes caused by distracted driving. But many of us have also heard of drivers phoning in reports of drunken drivers. In my own area, we have had several cases of terrified women desperately calling police to report that they were being chased at high speeds by murderous estranged husbands/boyfriends. All of these positive uses of phones in moving vehicles would disappear under a blanket ban. Are those losses outweighed by the benefits? I don't know -- but I don't think you do either. The burden of proof is on those proposing to change the status quo. Most people can be swayed to your side if the evidence is there, so have at it. But be prepared to show your work.

If a criminal commits murder and gets caught he will go "up the river," and perhaps fry once there.

Not necessary. The current federal Secretary of Transportation has already done that leg-work and is considering a proposal to invoke technology to prevent wireless communications in a moving car. His department is well aware of the large number of deaths that have already resulted from the use of wireless devices in moving vehicles by selfish, self-center members of the "me first" generation.
