Is this a real text? I think a scam

[ZZZZ5678]

So I’ve just upgraded my phone all online, got my messages and contract etc: but then I got a text from a number8101921 saying it’s o2 that I need to click this link to finish my contract for my o2 refresh, I haven’t clicked anything of course as I usually get a message from actually o2. And the link looks Odd as well, but it seems concerning as soon as I’ve upgraded I’ve got this text a few hours later?

Thankyou Cleoriff, I have had the same message straight after upgrading my o2 contract. I have reported it.

It's not actually a scam text.

Confirmed here in this thread by O2 staff member.
