AT&T quietly announced a new feature that they are launching tomorrow that while not exactly free is still a little interesting. They are going to start offering their customers unlimited calls to any mobile US number no matter what the carrier though there are a few gotchas. You need to be on AT&T’s unlimited messaging plan ($20/month for individuals and $30/month for family plans) and you need to be on a “select” individual or family plan. My guess they are doing that to rule out the bottom two tiers of family and individual plans like they have done in the past.
Still if you are on a “select” plan and plan on getting or already have AT&T’s unlimited messaging plan then you can sign up tomorrow for unlimited mobile calling at www.att.com/anymobile.
