I'm pretty sure call forward has been discussed on here in the past and the outcome was that it's not available on Skinny. Unless things have changed recently I'm pretty sure it's not available on Telecom prepay or Vodafone prepay either.
dacraka: I asked Skinny on Twitter and they don't support this feature. I think only Vodafone and 2degrees only support this.
Thanx folks. Pity they don't. Oh a lobby session coming on..
