It's a card that China Mobile gave you free of charge when it borrowed bohai university to send you a notice. There is 20 yuan in it, which can be used a few days before school starts. Actually, it is better to say that China Mobile wants to promote their business and then make money for them.

After all, Unicom is also very good.

One feature of this card is that the first few numbers of all freshmen in Boda are the same.

For example, when I was a freshman, it was1874165 * * or1874166 * * only the last four digits were different.

Hmm. How interesting

That's all I know.

Hope to adopt

Thank you! ! ! ! ! ! !
