BlynkSimpleSIM800.h: No such file or directory how to solve it a problem? Does any solution to solve it?

Difficult to say, based on the almost non-existent information you’ve provided, but I’d guess the answer is the same one as here…

I’d suggest that you provide significantly more information then, otherwise you’re unlikely to have much success in obtaining assistance.

@DavidTong Please don’t spam the forum by creating new topics about the same issue. I’ve merged your new topic into this one.

I’ve already pointed you to a topic which explains that you are using an outdated method, but instead of switching to the #include <BlynkSimpleTinyGSM.h> approach you are persisting with the outdated and now unsupported #include <BlynkSimpleGSM800.h> approach.

This is despite you saying that…

and failing to respond to my request for further information…
