The TMO @ Home service is a WIFI connection within your home or any other HotSpot like at your local Starbucks.... You'll get unlimited calling while connected to these servers. And when it first comes out you also need to buy a @HOME connection based phone. and the modem is supposed to be $49.99 with a $50 mail-in rebate, and you have to have broadbrand internet in order for these function to work correctly. Also, the modem gives off its own RF (radio frequency) and that will give you pretty much full service while connected. If a phone call generates while your connected to it, and then you stay on the phone and you leave and go down the street, or somewhere else, Its still free because the call generated from the location. Same way your nights and weekends work. If you recieve a call at 8:59 pm and you stay on the phone for five minutes it takes 5 whenever minutes off your allowed minute plan, but if you were to wait one more minute, those 5 were free.
Price on the WIFI @ HOME its $9.99 for individuals, or $19.99 for families and this is the promo price, not sure when its going up.
Service is expected to drop Early August, and T-Mobile is also getting a new credit program, where our highest deposit is supposed to be $175
