All HP Pro book 645 G1 machines have SIM card slot but over 90% of them do not have WWAN card installed. Did you buy WWAN card option ?

Then it does not have. WWAN card.

Integrated wireless wide area network (WWAN) options by way of wireless module (select models only)
Two WWAN antennas built into display assembly
Security provided by subscriber identify module (SIM), slot located in battery bay
Support for the following WWAN formats:

• HP hs3110 HSPA+ Mobile Broadband Module part # 723895-001
• HP lt4112 LTE/HSPA+ Mobile Broadband Module part # 704031-001
• HP lt4111 LTE/EV-DO/HSPA+ Mobile Broadband Module part # 704030-001

You can buy one of above parts and install to your machine.
