In 2010/2011 we used a Vodafone NZ 3G mobile broadband dongle with a NetBook, and used the same SIM in our 2G Sony phone.
This worked well, and we could get phone and data more or less all over both N. and S. Island.
This time we are bringing a Samsung Galaxy S3 (3G) for voice/texts and to use as a data source tethered to our Sony Xperia Z tablet (which doesn't have data capability/SIM card slot).
Our options seem to be a 3G mobile voice/data plan plus use of WiFi hot spots where they are available.
So any recommendations over the best plan for 2 month roaming?
I read that Telecom NZ include WiFi in their plan, but I have no idea how widespread the WiFi hot spots are.
P.S. I also see some mentions of using 3G dongles with Android tablets, but this also mentions rooting the tablet which I don't want to do. So anyone managed to use a 3G Vodafone dongle with a Sony Xperia X tablet?
