Configure Roaming Profiles⚓︎

==============

Roaming Profiles provide 3GPP roaming restrictions by defining which Carrier Groups a subscriber is allowed to attach to. They can be applied at the System, Site, or Subscriber level.

Understanding 3GPP Roaming Restrictions⚓︎

In 3GPP mobile networks, roaming occurs when a mobile asset leaves the coverage area of its Home Public Land Mobile Network (HPLMN) and attempts to attach to a Visited Public Land Mobile Network (VPLMN). Without explicit restrictions, a device might connect to any available VPLMN that has a roaming agreement with the home network.

Roaming Profiles allow administrators to enforce network selection policies, effectively steering roaming traffic by strictly defining the physical networks (Carriers/PLMNs) a device is permitted to use globally. This granular control is essential for: - Cost Management: Blocking expensive roaming partners and forcing devices to connect only to partners with favorable data rates. - Security & Compliance: Restricting attachments to trusted national carriers, preventing data from traversing foreign networks, and satisfying data sovereignty requirements. - Service Quality: Ensuring devices attach to networks that support specific features (like 5G SA) or offer superior SLAs and coverage, rather than simply connecting to the first available signal.

Carrier Groups⚓︎

A Carrier Group is a collection of Carriers used within Roaming Profiles to define sets of allowed or restricted networks. Before creating a Roaming Profile, you must define the Carrier Groups that represent the sets of networks you want to manage.

For detailed instructions on creating and managing these groups, see Manage Carriers and Carrier Groups.

Roaming Profiles⚓︎

Once Carrier Groups are defined, you can create Roaming Profiles.

1. Navigate to Roaming Profiles.
2. Click Add or select an existing profile to edit.
3. Type a Name and Description.
4. Select the Customer this profile belongs to.
5. In the Allowed Carrier Groups tab, select one or more Carrier Groups that subscribers using this profile are permitted to roam on.
6. Click Submit.

Applying Roaming Profiles⚓︎

Roaming Profiles can be applied at different levels of the hierarchy. If a Roaming Profile is set at multiple levels, the most specific one (Subscriber) takes precedence.
