How to open the virtual network?

What virtual network do you want to open? Because there are many kinds, such as public security network, which must be signed by the leader before being reported to the local public security bureau, government network and so on. Generally, it is enough to apply to the local mobile company. Monthly fee 10 yuan, free use of 6000 minutes is charged at 5 minutes per hour, which can be used by Shenzhouxing and Global Connect, but Unicom's number cannot be applied, and it can be used in about one week after application. But it's only free to talk to people who have applied for you in the virtual network. Not all virtual networks can talk. It depends on whether you have a virtual network for your friends. Just apply for the same virtual network.
