Resolution mms change

[_nulka7791_]

Hi, since some time without any setting change from my end I cannot attach more than one image to sms as it says that the size is too big. Moreover while I am attaching gif or a short movie, resolution of the attachment automatically changes in my chat chaina as well as for the receiver. It becomes blur and you barely can see anything. What may cause this? How to solve this?

Thanks, Ania
