In anticipation of moving my four line family plan from Sprint to AT&T, I'm trying to figure out how much it is going to cost me each month. I already have an iPhone but discontinued the AT&T service a while back because I was tired of paying for two services and just figured I would reactivate it once I was able to cancel my Sprint account and move all my lines over. Right now with Sprint my base cost for two phones is $70/month. That doesn't include data charges or other charges associated with my extra two phones. Total my bill is running around $170/month. That includes three phones with the basic $15/month data Sprint Power Vision charge plus one phone with no data capability. I am trying to figure what a comparable charge is going to be with AT&T with having one iPhone and the other three phones just regular phones (but two of them would need data access). Is there anyone out there that has a similar setup that would be willing to share with me what your average monthly bill is?
