[Q] Flashed CM12 To Galaxy S5(SM-G900F) and now I have no cell service topic

Hey everyone. I recently flashed the new CM12 rom to my Galaxy S5 and mostly everything works fine. The only problem I have is I can't make calls and/or send text messages. My carrier is Sprint and my model was formerly SM-G900P however after I flashed CM12 it now says SM-G900F. Whenever I click on mobile plan it says "Sprint has no known provisioning website". I can't even access the APN settings. Can someone please help me fix this, I love CM12 and would rather not go back to stock. I have no problems with my IMEI/MEID number, and under Status in settings my phone number still comes up however for Network it says "Searching for Service" and for Mobile Network Type it says "Unknown", it also says "Disconnected" for Mobile Network state. Is their any way to fix this?
