I just upgraded from a note 2 to a note 4 and moved my sim card over. I worked with carrier to set perimeters, but nothing I do will allow me to send or receive images. If someone sends me an image, the text app shows "multimedia message" with a download button. It never downloads. If i try with Facebook's messenger, a popup says blocked by carrier, but carrier denies it.
As an aside, this phone was originally on Verizon, and many of Verizon's apps can't be deleated, including the first screen when booted.
