GTA launches mobile number portability

9 Jan 2006

TeleGuam Holdings local exchange and wireless subsidiary, GTA, has upgraded its network to support mobile number portability (MNP). As part of the upgrade, the operator now owns its own signal transfer points (STPs); it had previously had to rely on STPs from other service providers. The island’s other mobile operators are expected to have completed their own network upgrades to support MNP by mid-February.
