SMS plus friends didn't send a message.

If you use a vivo mobile phone, you can't send WeChat plus friend verification. You can check the following troubleshooting methods:

3. There are too many friends verified on the same day. Please try again another day.

4. The WeChat account was reported;

5. There are sensitive words in the verification information or personal data sent;
