GSM international roaming allows end users to use their mobile service in countries around the world where international roaming arrangements are in place with carriers in those countries.
The International Roaming user guide 
(for registered resellers only) explains the things end users should know about using their mobile while overseas.
Activation
International roaming is automatically available to all resellers under the GSM Postpaid Resale agreement. However, it is at the reseller's discretion whether they wish to activate international roaming for any individual service. This may be done at the time of service connection/activation or at a later date upon end user request.
To enable an end user to use international roaming, the service needs to have the international roaming product code activated. This is done through the LinxOnline Mobiles (LOLM) interface.
