Not sure if this is phone or settings related, so will post the query here.
I have a Samsung Galaxy SII. When I receive a picture message all I get is a grey button which says "Download". When I press the button it disappears, and the word "Downloading" appears in the message body. After a while I get "Unfortunately, Messaging has stopped." I also had this when a friend sent me a contact.
When I send a picture message, the picture loads into the message correctly but it just says sending and then messaging stops. When I open messaging again the picture will still be there saying sending, but it never sends.
I have been led to believe this may be APN settings, but I have not been able to find a link to them on the O2 website, and the various other links where I have seen them have all varied slightly.
Thanks in advance, Jim.
