An easy way to rule out 02 or your sim card is to as a process of elimination insert your sim card in another phone and send a text.


Has both parties recently updated to Samsung One Ui  / Pie ?


If everything is fine via using another phone then you can try processes such as a back up and factory reset.


A Samsung Experience Store or Samsung Service Centre can run a diagnostic test on the phone.
