Using EDGE/GRPS with iPad and AT&T Plan
I have a new Apple iPad with WiFi and 3G, and I've signed up for AT&T's 2GB prepaid plan. AT&T's data coverage map shows solid dark blue where I live and work, so my data coverage should be fine there.
But I have a question concerning my plan's coverage where I vacation for a couple of weeks every year. That area shows the lighter blue, signifying EDGE/GRPS coverage. I do have WiFi available to me there most of the time. But if I need to turn "Cellular Data" on in the iPad's setting in order to make a connection ...
(1) does an EDGE/GRPS connection require that I also turn on "Data Roaming" in my iPad settings?
(2) are those EDGE/GRPS connections covered in my prepaid plan, or would there be additional charges for using the EDGE/GRPS connection?
