Whichever way you look at it, it's still not as good as the TalkTalk offer with its free AnyTime UK and international calls (to 28 countries).
Furthermore some of PlusNet's "comparisons" with TalkTalk features are either incorrect or misleading.
For instance it states TalkTalk's Technical Support is "£2 per call plus 10p/min".
In fact your initial call is 10p a minute (still way below most ISPS) and, if a query can't be answered immediately or requires additional support staff assistance, then a fixed charge of £2 is made.
That's still cheaper than a great number of other ISPs..:-)
