Thank you for your help @Bambino . But I logged into MyO2 on my desktop
to update my security information and it asked to send a verification
code to my phone and that came through from the same number as the
suspected fraudulent number. Very confuse...
Thank you. The initial text came from 65075 with my PAC code, then I had
multiple texts from O2 with verification codes so now I'm not sure as to
which ones are the fraudulent messages.
