Did you buy WWAN option for your machine ? Without WWAN option the SIM card is useless. Please check Device Manager, you machine MUST have one of the following option before you can yse SIM card
● HP lt4112 LTE/HSPA+ Mobile Broadband Module
● HP lt4211 LTE/EV-DO/HSPA+ Gobi 4G Module
● HP hs3110 HSPA+ Mobile Broadband Module
If not, you can buy WWAN card above and install to your machine.
