There is a note on the one-tel web site that the calls packages are going down by £1 each
http://www.onetel.co.uk/index.php/totalukcalls
currently 13.99 vs ntl 15.50
http://www.onetel.co.uk/index.php/Leisureukcalls
currently 4.99 vs ntl 9.00
There is no 60 min cut-off on one-tel, but there is a delay in making every call due to the box re-dialing.
One of the best bits I like about one-tel is the free fully itemized electronic bill (in Excel)
