AimQuest, which offers the Global Reach Internet Connection service, says it has signed up 82 service providers in more than 50 countries since it began operations in November. AimQuest spokesman Robert Lau said his firm was the only Internet service provider roaming service that offered a true TCP/IP (transmission control protocol/Internet protocol) network. Mr Lau said AimQuest could offer a better price because it did not lease bandwidth to offer the roaming service. He urged Internet subscribers to check services and roaming tariffs. 'AimQuest does not dictate how much our partners charge for using the service, but other roaming services are priced very much higher,' he said. Four service providers have signed up for the service in Hong Kong - Chevalier Internet, Hong Kong Star Internet, Asia On-Line and HKNet Co. Mr Lau said users did not need to make any software changes to connect to the system. 'All they need is to find out the access numbers in the city in which they want to use the service,' he said. AimQuest claims to cover 500 cities.
