T-Mobile announced Monday that it will extend its HotSpot @Home service to include businesses. Right now, the service allows regular consumers to make unlimited calls via a home Wi-Fi network (provided you have a UMA-supported phone), and if they wander out of range, the call will switch over to the cellular network.
Like the consumer model, businesses need only pay a flat monthly rate to take advantage of the unlimited Wi-Fi calls, though it'll likely take place over enterprise-grade Wi-Fi networks instead. This makes sense to us, since businesses have a lot more people wheeling and dealing over the phone. Right now the only real business phone that has the UMA capability in T-Mobile's lineup is the BlackBerry Curve.
