Hi again @wicks21!
Interesting that they told you that since it has always been like this since MMS was introduced.
"Although the standard does not specify a maximum size for a message, 300 kB and 600 kB are the recommended sizes used by networks." This information is taken directly from the wikipedia page about MMS.
I may have been wrong about a limit (there may be a hidden one in the service), but I haven't heard of any operator at least here in the Nordics that allow more than 400 kB.
Most users these days send videos and pictures using applications such as Facebook Messenger, WhatsApp and so on, where there isn't a limit, but it does require an Internet connection. This does however require that the counterpart has the same application and you have an account, so it's not as "smooth" as MMS, since this only requires you have to the phone number for the one that you want to send the files to.
I understand that it's strange when you receive two different answers, but trust me, there is to my knowledge, no setting in any smartphone device to increase the size of a MMS, it's the operator that decides the size.
