Did you face before to this problem:
We are implementing a Full MVNO. The problem is that when the user put his phone to avoid data roaming he took the network of our MNO as roaming and the user cant connect to internet.
The question is if we need to configure the MSC/SGSN to send a equivalent list during the LU or we need to put that list in the SIM cards User Controlled PLMN Selector with Access Technology field??
Plase send your comments..
