Yes, Sony Ericsson A200 had a bug in SMS picture decoding (old, monochorme, pre-MMS one) which was easily craftable into an exploit if carriers were allowing multipart SMS.

Guess what cell carriers did back then? Yes, they disabled multipart SMS

What else could they do?

Filter. Spam detection wasn’t exactly a novel idea back then either.

With what? Especially back then, I wouldn’t assume there is anything with a programmable CPU in the data path that can inspect and filter things at line rate.

SMS are sent between devices via a message gateway server.
