What is roaming?

Without getting too technical, international roaming services ensure that a mobile phone remains connected to a mobile network while the subscriber is abroad, or outside of the geographical coverage area of the home country network.

The mobile phone connects to a visited network (i.e. the network of a mobile operator in the visited country) which allows the subscriber to automatically make and receive voice calls, send and receive SMS and data, or access other services while travelling abroad.

In order for a subscriber to use a visited network while abroad, both the home and visited networks need to exchange various types of information. To do this, multiple interconnections need to exist between the home network and the visited network.

Comfone enables all of the necessary interconnections between the two mobile network operators to ensure the necessary information can be exchanged.

There are over 900 mobile network operators worldwide and they all need to be connected to one another in order to offer roaming services to their subscribers.

Comfone enables the various interconnections from and to all of the mobile network operators worldwide.
