T-Mobile USA has launched a service that lets customers place unlimited domestic calls with their landline phones over a broadband connection.

T-Mobile AtHome will cost $10 per month when it rolls out on July 2.  You will need a wireless plan that costs at least $40 per month, a T-Mobile Internet router for $50 and a contract to sell your soul to the devil, but apart from that it is catch-free. The router plugs into the home broadband connection, and the customer's corded or cordless phones plug into the router.

T-Mobile USA's Chief Executive, Robert Dotson, said that it will give punters an incentive not to be on a competitive land line service. It is targeted at users who do not want to give up their land line in favour of wireless. The technology is similar to the Voice over Internet Protocol, or VoIP, service offered by companies like Vonage.
