MMS settings for Samsung Galaxy S4 on O2 PAYG

Anonymous
Not applicable
I am trying to set my wife's Samsung Galaxy S4 up to send MMS. It can receive MMS fine, but every time I try to send an image I get an error saying "Error network problem".
I've tried texting ACTIVE to 2020 and installed those settings, but to no avail.
Why can I receive but not send?
She has enough credit, so it's not that.

Wouldn't it be cheaper and easier to send pictures by email?

Yes, I did have Mobile Data turned on however I turned it off and back on and then selected another picture and it worked!
Thanks for the tip.
I'm not sure if there's a strict limit on the size of images you can send over MMS nowadays. I was trying a photo I took the other day and they failed, then one I took in 2010 (likely much smaller in size) worked.

You can set a size for mms in message settings and the phone should resize them automatically.

Any idea where those settings are? The handset is on Android Lollipop

Thanks, the menus aren't exactly the same on Lollipop it would seem but I could find the AP settings. Nothing mentioned about file size though. I may need to phone O2 again 😞
