CNet reported today that T-Mobile will be entering the VoIP market in a very big way.

By launching their @Home service nationwide, T-Mobile will be offering a home VoIP telephone line to their current wireless customers. With unlimited local and long-distance (domestic) for only $10.00 / month, T-Mobile will certainly attract many new customers.

The telephone line will use an existing high speed Internet connection to send phone service to their equivalent of a VoIP adapter. This adapter apparently will also be compatible with their Hotspot @Home service.

That $10.00 a month price tag (plus taxes and typical fees of course) is an amazing price. And we’re sure some Vonage customers are already doing a double-take.
