Had a very nice guy (tho not totally up with the play) come door knocking at the weekend selling a Vodafone Broadband + Home Calling package. We are currently with Telecom/Xtra and on a 20gig plan and dont make toll calls so apart from a potential saving of a few $'s per month could not see the advantage of going through any potential hassle. His main selling point seemed to be ADLS2+ (pretty sure we are on ADSL2) but it seems to me Telecom are rolling this out with the cabinets anyway.
Our XTRA plan and connections seems to do everything we need it to do so would there be any real reason to change apart from maybe $16 / month (and I guess there would be a termination fee with Telecom to consider?)
