This may help others?
Samsung J330 phones stopped sending SMS a week ago, by trial and error I fixed the problem.
In phone setting networks/wifi etc. there is a setting "lte/2G/3G Auto" change this to "2G/3G Auto", for some reason O2 has stopped this legacy option from sending SMS

As a matter of interest are you a PAYG customer or contract?
