FP6.QREL.16.100.0, Android 16, DSDS (Lebara DK physical + Congstar DE eSIM). After deactivating a SIM and re-enabling, “SIM setup” hangs in infinite loop. Only full power-off + re-setup resolves. Airplane mode does not help. Occurs on every border crossing (DK↔DE), multiple times per month.
Reproducible: Deactivating physical SIM (slot 1) works. Re-enabling it triggers infinite “SIM setup” loop. Only physical removal + reinsertion resolves. eSIM (slot 2) is unaffected.
