T-Mobile and Fixed Mobile Convergence - Launch of an Unlicensed Mobile Access (UMA) service plan
The service is called HotSpot@Home. It is baed on Unlicensed Mobile Access (UMA)-based fixed mobile convergence (FMC) service. This allows their subscribers to make calls from home or from any T-Mobile Hot Spot via WiFi.
The service enables T-Mobile subscribers to make WiFi or cellular calls using a single number. They can also switch those calls between both networks. HotSpot@Home's introductory rates are around $10 a month to individual users' T-Mobile calling plans. If you need more lines for family members they offer a pakcage of five extra lines for $20 a month with family alling plans.
