Hi there @oldie 

I have not heard of this call from o2.

Always be concerned.

If o2 did send you this message they don't seem to be asking you to do anything.

@oldie Do not respond to any cold call, no matter who they say they are.

Don’t open any links or enter any information if you're sent a text.
