On my s5 I can't open multimedia messages

[AC Question]

Someone sends me a multimedia message and there is a button that says download, I click on it but it just loads and loads and loads until it basically times out

Confirm that your data is on and you have signal and 2. confirm that you have the feature turned on in your MM settings.
My wife swore up and down that she couldn't recieve MM messages until I checked her phone settings and turned the feature on.
I guess she was right, she couldn't receive the messages but I didn't push the subject.
