i'm not using the default SMS app that came with the phone,
instead i use some other app that is also called 'messages' which i guess is by Google;
anyway that app has following settings that may require Mobile data or WiFi connection,
i find those in Messages app under Settings>Chat features and Settings>Advanced;
so, that advanced messaging isn't there i guess, but 'group messaging' or 'chat'
Thank you. I'll have a play around and see if that works. My friends use the standard app with the phone I believe. I do have the other messages app installed on my phone but have never used it. The one that comes with the phone is currently set as the default app.
Do you mean the non standard messaging app. As in the one that doesn't come with the phone? I have that installed but have never used it. As far as I'm aware my contacts all use the messages app that come with the phone. Will give it a try. Thank you.
meanwhile i was able to check from where i got the messaging app from, i think i didn't like the samsung version layout, and you can see in the settings i posted screens from, it allows files up to 22MB , of course it is not sure that some software update made your phone go crazy 🤷♂️
anyway that is the one i use now, it is indeed by google->
