Hi, i bought a xperia z1 compact unlocked and am in canada. I cannot send/recieve picture or video messages over text, and i have that allowed on my contract and data is unblocked. I went to my provider and they started to set it up but ran into a problem, when try to set up an APN there is a area that says "APN enable/disable" with a box that is checked off but the box is greyed out and connot be changed, and my provider said that that was the problem with not being able to send/recieve pictures or videos over text. Please help how to i fix it so that i am able to.
