If unlimited calling for $99/month from anywhere plus unlimited messaging wasn’t enough, T-mobile has stepped up their game. With the recent event of Starbucks Hot Spots becoming AT&T domain, T-mobile needs a boost of confidence for their customers and $10 Unlimited calling via Wifi might just do the trick. The Hot Spot @ Home service has been around for some time, but has seemed to be another attempt to divert our attention from the lack of 3G connectivity on the T-mobile network and at $20/month it really was not appealing. The new service is cleverly coined as Talk Forever Mobile and it can be added to your account for $10/month and requires a special router, but with a Starbucks on every block there are plenty of chances to get your unlimited calling into action.
