I have a national 1G data plan on 2D. I noticed when in the PN CBD i was roaming on VF data as shown by a R in the status icon and checked when i went to Mobile Networks settings in my GN.
I think national data includes roaming but i also noticed a billboard near me advertising 2D 3Gb data.
So I rescanned the networks, found 2D and chose it.I was able to select the network and the icon changed to H which I presume means HSPA or something like that.
I wonder if 2D is available here why I roamed onto VF?
