Try to create more space, close apps, remove data you don't use and hope its not something other than memory

First thing you should do is restart your iPhone. If that doesn't work then delite unused apps, music, and videos. Also, make sure your apps are all updated to the newest version

Hi so two main reason bandwidth provided by the telecom company and the signal level.

If 1 particular one app, then it could be a problem with that app.
If every app, then try a restore.
