About Global Call Limited. Your Call Your World

About Us

Global Call Limited is a licensed ETS (External Telecommunications Services) provider in Hong Kong. Our focused business is to provide high quality and low cost IDD services to retail and business customers. We operate our own carrier-grade telecommunications switching facility and the IT systems necessary to deliver these services.

Our account managers are supported by a dedicated customer service team. To ensure service continuity, each business customer is assigned a specific account manager who is responsible for ensuring that all of its needs are met. Account managers also make sure that customers are kept up to date with the latest Global Call products.


High Quality Product


Our investment in carrier-grade equipment supported by SunTM, CISCOTM and HPTM equipment for our operating infrastructure.

We operate our technologies using international signalling protocols as adopted by countries like the United States, United Kingdom and Australia. We use lines directly connected to Tier One Carriers and we maintain excess bandwidth to ensure fast, clear, quality availability.

This investment in quality technology ensures that customers will not be faced with the inconvenience of sub-standard lines and associated issues such as distortion, slow connections, echoes, drop-outs, or similar problems.

Global Call Limited also uses a stand-alone system that constantly scrutinizes our Call Detail Records (CDR) system and billing system so that our customers have confidence in all aspects of their dealings with us.
