Rumor has it that T-Mobile is prepping the nationwide launch of a Wi-Fi service that would let customers use the technology to make voice calls with their cell phones. Hotspot at Home, which is currently in trials in Seattle, would expand on the carrier"s current Wi-Fi network of 8,000 Internt access hotstops. T-Mobile declined to comment on the rumors, which probably means the America"s fourth-largest carrier has something up its sleeve.
According to reports, when a caller approaches a hotspot while on the phone, his or her call will transfer automatically to Wi-Fi from the carrier"s regular network. The change is supposed to be instantaneous with no noticeable change to the caller. Of course, customers will need a dualmode Wi-Fi/cellular handset like the Samsung SGH-T709. Though the T709 had its debut last year with T-Mobile branding, we haven"t seen any further sign of the phone in months.
