Singapore Telecommunications (SingTel) has revealed plans to launch a series of 3G trials starting this Friday, in preparation for a commercial launch in early 2005. The operator said it will begin the tests in Singapore’s central business district, using 150 existing subscribers before expanding to other parts of the island later in the year. It plans to use feedback from the trial to determine when to start commercial operations. According to Executive Vice President Lim Chuan Poh, services could be launched as early as this year, although she said it is more likely to occur in the first quarter of 2005. SingTel, like its rivals MobileOne and Starhub, is required to have rolled out a 3G network by the end of this year, although commercial services do not have to be launched by then.
