NealR: I think you mean should we have built two networks. One from 20yr old technology and one from 3G technology.
Well from hamilton today, which is a long way north of taupo..
I had a strong 3G telecom XT signal as others did where I was but, my iphone was saying:
"cannot find a data network"
and we couldn't call out or call into Xt
We even tried calling from telecoms old cdma network into XT but nogo.
Which is why I was asking, if there where any backup/redundancy systems in place that will switch in when something like this happens ?
