Here's the thing. Games in ludong university are generally sponsored by China Unicom. I don't know why it is sponsored by mobile this year. It may be that there are not many students who use mobile cards, so mobile will make this decision and give the mobile phone card as a prize for the winning athletes. However, it is estimated that athletes will not switch to mobile cards. Unicom card has been used for so many years that there is no need to change it. Moreover, Unicom's welfare in Luda is many times better than that of Mobile, and they are not fools. Just take part in a fake sports meeting and hope to adopt ~ ~
