The size limit of WeChat sends files varies by scenario. 1. The maximum file sending in ordinary chats is 25MB, which exceeds the need to compress, split or share links with third-party tools; 2. FileHelper is also limited to 25MB, and it is recommended to upload the cloud disk and save it through the link; 3. The maximum file can be sent in WeCom (Enterprise WeChat), which is suitable for office use; 4. Voice messages are up to 3 hours, the pictures do not exceed 30MB, and short videos must be less than 25MB. High-definition videos are recommended to be compressed or sent through WeChat Moments. If you cannot send large files, you can choose WeCom or file sharing link to solve the problem.

You can use WeChat to not bind your mobile phone number, but you need to bypass the default registration process. 1. Select the email instead of your mobile phone number when registering, and verify the email number; 2. Log in through your existing QQ or Weibo account, and you may not need a mobile phone number; 3. Use the "Device Transfer" function to log in on a new device and skip to re-verify your mobile phone number; 4. Log in through the desktop version, provided that the existing device is logged in; 5.

Observe the other party's online status, reply speed, avatar signature changes or withdrawal of messages to make speculations; 3. Indirectly test the reaction by pulling in group chat content, @ reminder or initiating video calls, etc. Although these methods are not absolutely accurate, they can improve judgment accuracy in combination.

WeChat occupies a large amount of storage space mainly because of media files, cached data, chat records and applet content. 1. Automatic download of media files leads to accumulation, especially in group chats, which are not easy to detect; 2. The cached data becomes redundant over time, including avatars, web pages and mini-program caches; 3. Long-term chat records and backups hide space, and forwarding messages and documents gradually accumulate; 4. Mini-programs and browsing content will also retain local data, adding additional burden. You can free up space by turning off automatic downloads, regularly cleaning caches, selectively deleting chat history, and managing applets.

If your WeChat account is blocked or has limited functions, it is usually because it violates community norms or usage rules. Common reasons include: 1. Send too many messages in a short period of time, especially mass marketing information or duplicate content; 2. Use unofficial plug-ins or automation tools, such as automatic reply, like-brushing software, etc.; 3. Reported by other users, such as complaints caused by harassment, inappropriate remarks or spam; 4. Account security abnormalities, such as logging in other places or equipment changes triggering the risk control mechanism. The response methods are to avoid mass sending, not use third-party tools, pay attention to words and deeds, and share content with caution, and bind mobile phone numbers and email addresses to improve security. If the error blocks are mistakenly blocked, please contact customer service to appeal, otherwise you usually have to wait 24 to 48 hours to lift the restrictions.
