T-Mobile brings VOIP to iPhone

Internet protocol (VOIP) calling service for iPhone and iPad users, even though it does not sell those devices, PC World reports.

The operator is expanding its free VOIP service, called Bobsled, to iPhones, iPads and Android phones. Users with the app can make calls to mobile or landline phones in the US, Canada and Puerto Rico without incurring charges.

Initially, the app would let people make VOIP calls only to Facebook friends from PCs, PC Advisor states.

In October 2011, it began letting people make calls from Facebook to mobile devices and make calls from PCs to US mobile and landline phones.

ITProPortal says T-Mobile unveiled a separate app for Android device owners a few days ago, with a Bobsled Messaging app specially designed for Google's platform. Users can download the T-Mobile messaging app on their Android tablets, and tie it to their mobile phone numbers, so any message sent via T-Mobile's app can display their mobile number.

Brad Duea, senior VP of marketing for T-Mobile, explains that as VOIP services become more in demand, the carrier is ready to sacrifice a part of its revenue in order to get the customers' attention.
