I can't really answer that, except to say that many WWAN modules that fit in there in terms of dimensions and connections actually work. Actually, because HP has built in a lock here: Even if, for example, various HP modules and third-party modules would work, the BIOS has a fixed definition of which components are permitted (cannot be read out in the BIOS view). All others are acknowledged with a beep sound and a message when booting. The laptop runs perfectly, but the WWAN function is deactivated. In other words, HP is playing the card of protecting its own market here. Only original HP parts and only the very specific models. No chance to change the BIOS (or there are hacks, but the effort is too high in my opinion). In any case, I would google more extensively, also in English, or ask the HP hotline/support to find out the correct product number. It's really tedious. Good luck.
