I've just noticed that on the Xnet VFX calling rates page there are different prices for calling cellular customers in Canada. As the NANPA prohibits certain prefixes for mobiles only (with the exception of the 600 prefix), how does WorldxChange 'know' which type of phone is which? Would I be correct with the assumption that the other providers that WxC use for the completion of the call (Bell, Telus, Rogers) give out the information?

That said, I called a couple of mobiles in Canada a few weeks ago and I was only charged $0.05/minute (604 and 250 prefixes) - is the rates sheet out of date? or was I just lucky..?
