Imsi Transfer Agreement

23. september 2021 Slået fra Af Patrick

When a subscriber starts roaming on a foreign network, he can rely on one of the different communication networks available within the geographical area concerned and having a roaming agreement with the home network. Nevertheless, such an automatic application may currently be unavailable in many countries and, if available, it may be too expensive for the MNO to provide it. In this case, it may be necessary for the end user to manually change the IMSI from Home IMSI to roaming abroad and manually change the IMSI from Roam IMSI to Home IMSI when the end user returns to their home network. This can be done for example with a SIM Tool Kit application. In addition, as has already been said, the transition from Home IMSI to IMSI ROAMING and vice versa is only possible if the home network has concluded an agreement with the visited network. Operators need to develop new bilateral agreements with selected partners who still use hub-based services for other destinations, which can be costly and time-consuming. A SIM card usually contains only one IMSI. If the home network of this IMSI does not have a roaming agreement with the network to which one of your devices wants to connect, it cannot connect to that network. Nor any of your other devices.

The network architecture of the eUICC is designed in such a way that it is not possible to transfer data between channels or profiles, as it requires the authorization of the central certification body guaranteeing legitimacy and not interference between profiles. The BroadForward Multi-IMSI Roaming (MIR) solution enables operators to provide their partners with sponsored roaming services for language/SMS and data. . . .
