if I'm roaming, how will the VLR from the MSC serving me download my subscription details? Via GMSC? Can you simplify the route it will follow to fetch the details to store in local MSC VLR? for eg: GMSC > GMSC-2 > MSC-2 > HLR-2 > MSC-2 > GMSC-2 > GMSC > MSC (VLR) - might be incorrect but just expressing how I wish to understand the call flow.
