Default No cell signal in custom ROM

I am using a custom ROM from xda (it is 1.2GB in size, not AOSP). However, there was no cellular reception at all. So I checked the phone setting, it just didn't read out my phone number, baseband info... see the attached pics. However, when I restored back to stock ROM NAE, phone could find the signal and showed my phone number correctly. What might be the reason here?
