Why can't Yuyao's campus card cornet send short messages to Ningbo's?

It should be that your virtual networks are different. Yuyao and Ningbo are both from Zhejiang Province. You can open a high school link so that you can send text messages and make phone calls. After opening, you can play with all the virtual Netcom schools in Zhejiang Province, and then the trumpet will become a 600+ trombone.

I'm here in Ke Qiao, Shaoxing, and I think you should also have it there.

If you don't know how to open it, you can ask 10086 labor service.
