Why is the net profit difference between China Unicom and China Mobile so great?

Unicom and mobile, this problem is hard to say.

Personally, I think mobile is doing well, or channels and terminals are enough.

In addition, the investment in mobile is also great. We should also invest heavily in the construction of base stations and the like.

There seems to be no signal in many places of Unicom. . . ?
