Why can't I get all pictures or texts sent to me?

AC Question

I have an HTC one m8 and since the newest update I haven't been receiving the texts sent to me. It happens a lot at night, I won't get any of the goodnight texts sent that I know have been sent. Like my friends will show me on their phone that it sent but I won't get them. Is this an issue with my phone or my network or what? Also I can only get 2 pictures sent to me at a time. How can I change that? If someone sends me multiple pictures I only get two of them? Do I have to take my phone in, it's getting really aggravating especially when I don't know if someone has replied to a text of mine.

Thanks
