A friend of mine was on Orcon Unlimited VDSL with Genius phone, He was having trouble with the phone, so they let him out of the contract.
He moved over to Telecom VDSL with a normal phone line.
He used to get 44mb/s download sync speed on Orcon, But since moving to Telecom, He gets 62!
Why would this be? Perhaps he was on the wrong profile
