According to an unconfirmed report, T-Mobile USA is going begin offering UMA service soon.
UMA (Unlicensed Mobile Access) lets devices make use of cellular networks through short-range wireless technologies, including Bluetooth and Wi-Fi.
Supposedly, T-Mobile is going to use UMA to offer customers a way to make unlimited phone calls for a very low monthly fee.
The down side of this service is it will require a special Wi-Fi router and a phone that supports UMA. Reportedly, T-Mobile will be offering the routers to customers to install in their homes, and UMA service will likely be added to routers at T-Mobile’s hotspots around the world.
Naturally, demand would be low for a phone that works only near a specially-configured hotspot, so the carrier is expected to offer UMA-capable devices that can also use its GSM network. According to a rumor from earlier this year, T-Mobile will begin offering a smartphone from its Sidekick line with UMA support before the end of this year.
Reportedly, this carrier will begin offering UMA service on September 12 in Seattle and a second city, as yet unknown, city.
