When XT were the most expensive data carrier i got speeds of 7Mbps+
But I switched to Voda and go no coverage. Switched to 2D and got 7Mbps+ off peak and 2Mbps during working hours.
Since they were the first to become the cheapest ($19/500Mb) i signed back to XT to get the best coverage. Best coverage I get, but worst speed. I'm not complaining because cheapest = most congested, I udnerstand that.
Normally it gets pretty congested during working hours in Dunedin I get 1-2Mbps.
Since the Uni restarted I'm getting 300-500kbps in CBD
I am considering 2D (and Voda if/when they do 900MHz in hilly Dunedin) ...
Just saying :D
