It is free to talk to each other for 400 minutes in the virtual network. If you answer the phone and handle the one-way charging service of the virtual network, it is completely free for you to answer the virtual network phone. If you don't handle the one-way charging service of virtual network, you should also deduct the corresponding virtual network minutes when others call you. I also study in Hangzhou. Our virtual network makes virtual network calls all over Hangzhou, which is the same as making virtual network calls at school. When making a virtual network call outside Hangzhou, both parties will deduct the minutes of the virtual network regardless of whether the one-way charging service of the virtual network is handled. Outside Zhejiang Province, the virtual network is invalid.

I can guarantee the above.
