After two years of trying, I was able to get photos from my dumbphone sent over to my FaceBook page. Two years ago FB changed their settings and I couldn't figure out how to fix it.
But earlier this week I tried again and I'm good to go.
I signed up for the FB mobile, this generates an email address. I thought I had to use email to send the pictures and that cost data money and we don't have a data plan, so I never tried it. Well, last week I tried it because I read in a forum that this doesn't go against data.
And it doesn't! Sending a text to email doesn't count against data, it counts against my messages.
