Phone [Q] No SIM card installed

HTC One M7 1.29.401.13, H-boot 1.44 unlocked bootloader, S-ON, Cid 032


This icon is always present, with and without SIM card inserted


*restored the phone to stock ROM
*tried different SIM
*airplane on & off few times
no change !

When I use dialer, Connection problem or invalid MMI code message pops up

in service menu, network is set to to WCDMA,

tape solution makes no sense, that icon is always present
