Wechat voice is temporarily unavailable.

1, the other party may be in a network-free state, that is, the other party's mobile phone may be in flight mode, or mobile data is not turned on, WIFI is not connected, or it is in a signal blind area, and it is temporarily unable to access the Internet. In short, the other party's mobile phone may not be able to access the Internet normally at this time.

2. The other party may be making a voice call or a video call at this time, just like we usually make a phone call. If the other party is on the phone, you can't get through. We can call again later.

3. Fang may not have his mobile phone with him at this time or his mobile phone is not with him, so he can't answer it naturally. Naturally, there will be no answer at the back, which will happen to all of us.
