Unable to send videos on any messaging platform

Hola, 

I am having an issue with a new phone of mine. I just switched over the UnPlugged Phone, which I know isn't as common as most other phones, but I thought this was odd. I am unable to send any videos due to file size. I have tried sending a 1 second video that was compressed, as a test, and it still wouldn't send. I'm unsure what to do. I have tried multiple messaging platforms outside of the Signals, WhatsApps, etc (those apps voluntad send videos just fine), and none of the platforms are able to do it. I don't know if it's a MMS setting or what. But I just want to be able to send videos on my default messaging platform without having to switch to something else where the other user also has to have that app. 

I know that most will say it is a phone issue, since it is not as common as the primary phones, but talking with other users of the phone, this doesn't seem to be a common issue. Just wondering if there was a setting I haven't tried or something. ¡Gracias de antemano!
