Ludong university Mobile Mobile Card is better. From the perspective of Luda, ludong university Mobile is better than ludong university Unicom. Ludong university Unicom can't get along in Luda, and few of them are useless. They often charge fees at will, forming a vicious circle over time. I suggest that ludong university Unicom reflect on it, focus on how to serve our students in Luda University, and hire people to spoof mobile all day. This is not long-term. Our classmates all know very well, Unicom, please don't say that you have anything to do with our Luda University. I sympathize with those students who are charged at random.
