WP7607 remote sim failed

Hi,
tried different FW/SDK:
SDK for WP76 (Release 9 + Legato 18.08.0)
SDK for WP76 (Release 13.3 + Legato 19.11.0)

remote sim doesn’t work:

Jan 20 19:24:56 swi-mdm9x28 user.info Legato:  INFO | rSimDaemon[9197]/rSimDaemon T=main | le_rsim.c le_rsim_Init() 1725 | le_rsim_Init called
Jan 20 19:24:56 swi-mdm9x28 user.err Legato: =ERR= | rSimDaemon[9197]/rSimDaemon T=main | le_rsim.c le_rsim_Init() 1757 | pa_rsim_AddSimActionRequestHandler failed

Module: WP7607

any tips?
anyone had luck to make it work?
