Under what circumstances will you chat with a person who has WeChat and does not have WeChat, and send a lot of messages?

The following are some possible situations, which may cause a person to chat with people who have WeChat, instead of using WeChat, send a lot of messages by SMS:

1. Network connection problem: If two people's mobile phone signals are unstable or one of them has a network connection problem, this may cause WeChat chat to be delayed or unable to send messages. In this case, sending information by SMS may be more reliable, because SMS can send and receive information without network connection.

2. Technical problems: If the version of one party's mobile phone system is too low or there are other technical problems, this may lead to the abnormal use or non-normal use of WeChat chat. In this case, it may be safer to send information by SMS.

3. Privacy protection: Some people may want to protect their privacy during the chat, for example, in public places or when they don't want others to see the chat content. In this case, it may be safer to send information by SMS, because SMS can set encryption protection and privacy protection functions.

4. Information length limit: WeChat chat has a limit on the length of information. If you need to send a lot of information or transmit a lot of files or videos, it may be more convenient to use SMS.

5. Different communication needs: Sometimes, it is more convenient to use SMS than WeChat. For example, when a person needs to send multiple messages quickly or track the sending and receiving of information, it may be more practical to use SMS.

In short, which communication method to use depends on personal needs and circumstances. When choosing communication mode, we need to consider factors such as network connection, privacy protection, information length limitation, technical problems, communication requirements, etc.
