Morning Harald, thanks for getting back to me. For a little more context, the problem I'm trying to solve is that I've written an android application to update EF.IMSI, but I don't have a way to inform the UE of changes to the files on the SIM. TS 31.102 has a note in Annex A that says if EF.IMSI is changed through proactive UICC commands (which I'm NOT using, I just thought this was a helpful reference), a REFRESH command should be sent which would cause a 3G session reset which in turn updates the UE about changes to the filesystem. Since I'm not using proactive UICC commands (and it's my understanding that if I wanted to I would need to write an applet to support that, correct?) I'm wondering if there's any other way for me to trigger a 3G session reset. For context, the method I'm currently using to make changes to the files is to simply open a logical channel with ADF.USIM and send the SELECT and UPDATE BINARY APDUs over.
