freitasm: This completely makes things more expensive. You have to pay $45 for NDSL and not have a landline. So you need to sign up for a VoIP provider, plus an ISP.
At the end of the day you will be paying at least the same, if not more, for a good service and connection.
Sorry! You've lost me there Mauricio

How do you work out that it is MORE expensive?
There is a saving of $29.95 per month to be had, less the ISP charge which may be as little as $10 if past experience (from the pre UBS days) is anything to go by. This would probably include some small amount of data, much as the $29.95 type plans do now. If NDSL customers choose Xnet, if may be an even smaller fixed charge, and then $1 per GB as they charge now.
I don't see any way that it can possibly work out MORE expensive. There should be at least a $20 saving to be had, whichever way you look at it.
Out of that, NDSL customers will need to pay for Voice Services. Again, if past experience is anything to go by, WxC are likely to offer VFX to NDSL customers with free line rental and free local calls so long as they use Xnet for their ISP. All supposition on my part, but this has been their policy to date.
