Multi-IMSI Roaming solution (MIR)

The BroadForward Multi-IMSI Roaming (MIR) solution enables operators to provide sponsored roaming services to their partners. The software solution offers a wide range of flexible signaling capabilities including smart IMSI translation between the Sponsor IMSI and the Home Mobile Network IMSI. The BroadForward Multi-IMSI Roaming solution is in use at operators worldwide, including Europe’s largest mobile operator group.

Sponsored roaming services
For operators around the world, it is attractive to provide so-called sponsored roaming services. This way they can allow business partners to instantly leverage the operator’s (regional) coverage and roaming agreements via its roaming partners. It means these partners don’t need to build their own worldwide network of roaming partners and agreements. That would take years. With the sponsored roaming service, operators can offer their partner’s customers better international coverage against lower costs, while keeping their own telephone number.

  1. Multi-IMSI SIM-card which contains 2 IMSI’s. IMSI 1 is the home IMSI and IMSI 2 is the sponsored IMSI.
  2. Mappings between IMSI 1 and IMSI 2 are maintained in a database on the MIR.
  3. The home PLMN does not need to know IMSI 2 for each subscriber. Instead the subscriber remains provisioned with the existing IMSI 1.
