HD2 MBX 5G SIM PIN required or incorrect


I have a problem with KPN (NL) SIM’s in multiple HD2 MBX 5G routers, they all have a Thales MV31-W modems.

Modem with KPN SIM uses firmware T99W175.F0.

Modem with Vodafone SIM uses firmware T99W175.F0. and works fine.

do specific networks use specific firmware?

Please upgrade your HD2 MBX to 8.2.0 then upgrade the cellular firmware from support.cgi page to confirm it helps.
