Here is a little tutorial:
1. Download your zip file;
2. Copy zip file on the root of your SD Card;
3. Reboot your phone on custom recovey TWRP or CWM
4. Install the modem
5. Reboot your phone and wait for the GSM signal to appear;
6. If your signal is no good repeat steps 1 to 5 with another one.
Allways make backup !
