I have heard second hand that Vodafone has insufficient capacity in Central Otago. Something like half the connections required to support the network. I ask this as I found my Vodafone 845 just dropping all signal and then all of a sudden full signal (this is in the middle of 'town' not in the wops.).
So I bought another phone as I hated that phone and thought the radio in it was crapping out, but exactly the same thing is happening with my new phone.
Anyone in central having similar problems?
