Well I've managed to last 6 months on 2 degrees and as much as I love my plan I can't live without mobile reception at home. It isn't mobile specific, were simply to far from the nearest Vodafone Cell site, but with Telecom I'd have 5 bars of coverage.
I'll probably drop a 2degree's pre-pay in a phone to keep an eye on coverage to see if things change in the future, meanwhile I've got the pleasure of paying Telecom nearly twice as much per month for similar minutes and data.
