When a user consumes data in the Local Break Out (LBO) roaming mode, the actual data usage is not visible AFAIK to the home network. The CAT offers an event for call control but I don't see a functionality to monitor the data usage. Also in the USIM file system I see no file recording the data usage, again I see only files for the call metering.
Is there any chance to get the amount of consumed data from an applet?
