It's nearly impossible to use a smart phone without a data plan. If you just need a voice phone, why not get such a thing? And you didn't tell what country and how many minutes you need. My son has that virgin mobile plan but will that work for you?
I am part of a AT&T network with a Samsung infuse smartphone. I have never used the data link or the wi-fi link I did all downloads through a network computer. The only features I want on a cell phone is Voice, Calender, contacts list and camera (download to computer through physical link). Is there any phone that provides those features without a data Plan? and what plans are available for the voice only function?
