I know almost nothing about phones, but stumbled onto a solution for not being able to download pictures sent to me as an attachment to a text message. First, click "settings," then "more ...," then "mobile networks," then check the box for "data enabled" to "enable data access over Mobile network." Then make sure your WiFi connection is turned off. If I do these things and still can't download a picture attached to a text message, I just turn my phone off and then back on and presto, the picture downloads and appears. I live out in the country and a weak connection to the phone network may be part of my problem. I hope this helps you. I am looking forward to the day when I can fix my phone with my Winchester shotgun.
