First, I apologize if I am in the wrong area, but I need some help making a decision quickly. We are AT&T customers with 5 iphones on one account. We have all previously been on the 2 year contract and upgrade at different times over the two year period (iphone 4s-6s). I recently visited the AT&T store and while I was there was told about the Next Plan. The salesperson assured me that we would save a lot by slowly switching to the Next Plan as we upgraded our phones--she said that we can switch right away to the shared data instead of what we have now ~1GB of data per person. The 5 of us typically use less than 5GB of data(use a lot of wifi) all together and very few minutes. We have been sharing 250 (?) minutes and unlimited texting--the lowest plan they have for minutes. We pay about $25-30 per phone for the data and then also pay for the additional lines ($10 each I think?). We keep the phones for 24 months before upgrading. Is it a good idea to switch? The salesperson also said they were probably phasing out the 2 year contract by the summer. I also have a tablet that I pay per month through Verizon that I could add to this plan if it saved me money. I just don't want to get locked into something that doesn't make sense. Thanks for any help you can offer! I have a feeling buying outright is always the best but can't really afford to pay out $650 at one time!
