Signs on to mobile network and makes and receives calls but can't get

Hi @jules051363 ,

Check if the mobile data setting has been enabled.

Go to Settings > Network and Internet > Mobile Network > Mobile Data

If this setting is disabled you won’t have internet access or be able to send or receive MMS messages (texts with pictures, video etc). You can still send/receive SMS messages however.

Also it is a good way to control your data download (if limited), as disabling this setting prevents any apps from downloading in the background without your knowledge
