Why didn't WeChat send verification information?

The reason why WeChat can't send the verification message is:

1. Bad or unavailable network;

2. The added friends will add you to the "blacklist";

3. The micro-signal was complained by others because it was invisibly degraded;

4. WeChat profile contains sensitive characters or friend verification application information is illegal;

5. Friend settings refuse anyone to add.

Details are as follows:

1. Make sure your network is available. If the network is not good or available, adding friends will naturally fail.

2. It is possible that your friends will add you to the "blacklist", so you will inevitably fail to add.

3. It is also possible that your micro-signal was complained by others, and then your WeChat was invisibly downgraded, which made it impossible for WeChat to add friends.

4. It is also possible that your WeChat profile contains sensitive characters or the information of your friend verification application is illegal, and all your friend adding applications will be automatically blocked by the system, resulting in the failure of adding friends.

5. In addition, some friends often receive applications from strangers to add friends, but they don't want to add strangers, so they set to refuse anyone to add. Therefore, friends cannot be added successfully.
