New AT&T Data Plan Saves $15 Monthly By Staff Reporter | Dec 05, 2013 03:16 PM EST AT&T made a couple big announcements today for smartphone users. Most significantly, the company has decided to offer separate pricing on data plans for users who bring their own smartphone, purchase one at full retail cost without a subsidy, or simply have an expired contract.According to the carrier, the new data plans, which will be offered under the AT&T Next banner, will offer customers a $15 per month savings on Mobile Share Value Plans.âWith our new Mobile Share Value Plans, customers donât have to compromise,â said David Christopher, chief marketing officer, AT&T Mobility in a press statement. âOur new no contract option lets customers add a smartphone to the nationâs fastest and most reliable 4G LTE network at a lower monthly cost. Customers want great value and a premium network - and now they can save more and get unlimited talk, text and data to share.â The move by AT&T to offer contract-less services comes after T-Mobileâs UnCarrier initiative, announced earlier this year and offering a similar value proposition. While the new AT&T plans will save money for some customers, they likely wonât seem very attractive to users with grandfathered unlimited data plans at $40.In addition to the new data plans, the company also announced an 18-month upgrade option that will become available to consumers, as well as âselect small business customersâ on December 8. The plan works by allowing subscribers to upgrade their device every year and a half, while spreading out their payments over 26 months. No upgrade or activation fee will be charged. According to Android Central, AT&T subscribers under expired contracts will automatically be migrated to âcheaper, off-contract pricing.â While this is great for most users, itâs decidedly terrible for anybody on the aforementioned unlimited data plan. While itâs more likely that Android Central overstated, it still wouldnât hurt to check in with AT&T since itâs impossible to re-add unlimited data to a smartphone once itâs removed, even by accident.Currently, AT&T offers unlimited data only for non-smartphone users.
