GCS’ popularity is obvious

With over 110 operators connected to Comfone's International Roaming Platform (IRP), GCS has established more than 3000 roaming relations since its launch in 1997.

Designed to provide an efficient alternative for implementing and managing large numbers of roaming relations in a short time span, Comfone GCS represents a revolutionary method for establishing international GSM roaming. With only one signalling connection and one single agreement, GCS provides almost immediate roaming with
many GSM networks worldwide, as long as the requested networks
agree to the connection.

Global Cellular Service is a complete roaming service. Comfone specialists provide the additional benefit of a roaming management service, which handles all roaming issues between GCS members, including contract negotiation, coordination and administration.

Comfone's International Roaming Platform maintains consistent service levels to match the increasingly sophisticated and changing expectations of mobile subscribers today. This translates into a competitive advantage for mobile operators, aiding them in generating more roaming revenue faster.
