During Order Decomposition, the customer order may contain lines related to their ability to roam, for example:
- Whether they are allowed to roam to other networks
- Which countries and/or networks they are allowed to roam to
- The duration of any allowed roaming
- Restrictions or limitations on use while roaming
During Network Configuration, home subscriber profiles in the HLR/HSS may need to up updated to reflect the roaming options for customers.

Additionally, configuration to handle outbound voice, data and message requests from roaming subscribers of partner networks – possibly received from GSMA via IR.21 RAEX updates – may need to be applied to the VLR (2G/3G), MME (4G) and AMFs (5G) systems.
Porting may require additional network configuration to re-route inbound requests to ported-out subscribers to their new home network, if this is the network architecture supported by the regulatory agency.
Usage reports (CDRs, IPDRs, etc) for subscribers from partner networks who are roaming onto this network will need to be collated and shared to their home network provider according to the agreed interface (Interconnect). Invoices will be generated and issued at agreed intervals to represent the charge to a partner network from its home subscribers roaming onto this network.
Additionally, partner networks will share usage information for home subscribers who are roaming onto their networks.
This usage information must be validated, and separately allocated to customer usage accounts on the Billing system, if appropriate. Separately, partner networks will send invoices for the services used by home subscribers roaming onto their network (Invoice Handling).
These invoices will need to be validated; separate line item charges in the invoice will need to be allocated to the relevant customer Billing accounts in the Billing systems; and the invoice will need approving and paying in line with the agreed terms.
