So this may be an old topic but there does not seem a clear answer to this.
I am trying to send a text “Hello World” to check that text are working from my mobile phone using the message app that comes with the phone. This app supports both text messages and mms.
But the network refuses to send the message as I get “MMS not supported”.
There are no special images with this message so it should be treated as a normal text message not “MMS”
I did not have this problem when I was with THREE who is effectively the same network
Do I now need to use a different app or how to I change settings to resolve this. I do not want to send MMS messages just text messages or at least the same functionality I had with THREE
