?Why can't I open a mms that was sent to me?

[AC Question]

I can't open an mms even though I'm connected to the internet. Why is that? And there's no notification if I receive an mms.

If it's a file type that you don't have an app to open, it won't open.

If the MMS section of your phone's APN isn't set correctly, you won't receive the MMS.
