Gsm Home Phone

I want to get rid of my AT & T fixed. I'm looking for a solution where I can use my existing DECT handsets or buy a new cordless phone system that can connect to a GSM network (T-Mobile) network directly. I'm not looking for a VoIP solution. Appreciate your help on this.

T-Mobile offers service called @ Home.
its a bit to do.
You can use the same phone for GSM calls and calls to the house via a router that you will receive by mail. It is an addition to wireless T-Mobile for $ 10 extra. The catch - you must have broadband internet at home.

Find in T Mobile hot spot at home, they offer mobile phones with wifi that will give you unlimited minutes if you use the wifi to call anyone in the United States. They also offer a cordless phone to work off this feature too!
