You should try to apply both of them, if one does not you need to try another one.

means those driver do not suite your device. This might be because drivers meant for different OS or version of it like 32/64bit.

If you have driver problem go to device manager, right click on one of the lines under “other devices” that belongs to your modem. Select properties. Select details tab and choose hardware IDs, provide text from that window to us please. Repeat this with all lines of your modem that appears under other devices.
