I wouldn't touch the Edge Plan with a 20' pole. As with AT&T's Next, they seem to be rip offs. They bank on you giving in and upgrading each year, thereby keeping your phone and reselling it as a refurb. The Edge plan will cost you more. I have 4 phones on Verizon's More Everything Plan. I'm happy with that. Unlimited text and talk, 4 shared gb of data, free international texting, and free cloud storage for $247 per month. Verizon has a new single line plan for $60 a month. Unlimited text and talk with 2 gb data. That's a good deal if your on wifi a lot.
