my contract with AT&T ends in january and im thinking about getting a contract with someone else. i was thinking about nextel for the walkie talkie thing with a few of my friends and my g/f wants one too. does anyone have nextels on here? are they any good? what i hate about AT&T is that as soon as i leave town i lose service. so what are yall using, what do you like/dislike about it? sprint, cingular, at&t, nextel tell me about em.
