Chosen Solution

I can take photos with my phone and attach them to text messages but am then unable t send any messages with photos attached. This was not always the case as I was previously able to send text messages with photos attached. Can anyone advise on how to solve?

Do you have a data connection? MMS messages require a cellular data connection to successfully send.

It could be a problem with your messaging plan. That is the most mundane answer, and also the easiest to fix.

They want you to turn on imessages. Got to Settings, go to messages and turn on imessage and make sure MMS messaging is on. Whether you want it or not, that is how they set it up. Ummm. I wonder why.
