My mobile phone sometimes receives short messages very slowly. What’s going on?

The reason your phone is slow is because there are too many things in the download cache. Just use Tencent Mobile Manager to clean it up. It has a special one-click optimization function that can clean up junk on your phone with just one click. But you can rest assured that it will only clean up unnecessary data in your system to free up space, and will not delete your important information. Also, remember to use Tencent Mobile Manager to close background programs when you use your mobile phone. This can also effectively speed up your mobile phone.
