Roaming is defined as the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services when travelling outside the geographical coverage area of the home network, by means of using a visited network.
It is technically supported by mobility management, authentication and billing procedures.

If the visited network is in the same country as the home network, this is known as National Roaming. If the visited network is outside the home country, this is known as International Roaming(the term Global Roaming has also been used).

If the visited network operates on a different technical standard than the home network, this is known as Inter-standard roaming.

GSM Coverage Maps is a unique resource containing information supplied and approved by the members of the GSM Association. Network, Services and Roaming information are continually updated to reflect the evolving situation worldwide. Interactive coverage maps, updated quarterly, allow you to navigate to see where exactly you can use your phone.
