Anyone has an idea how attachment of a multi-sim devices occures in either 4G or 5G?
Multi-sim: a technology,just reading about it in Orange France, where you can use the same number (MSISDN) on the same mobile / tablet / car… at the same time.
I think here the HSS is mainly involved for mapping the same MSISDN to different IMSIs.
What I think is that the network attachment will be normal as any 2 different devices.
Any other ideas about that?
