Last night at 23.45 I received a txt purporting to be from Telecom 7466 as follows:-

From Telecom: You should now be receiving a text(s) that will change your phone's settings. Save these settings using PIN: 1234 if needed.

Anybody have any idea what this is about? Certainly nothing else has been received since.

Thanks In Advance for any pointers that will stop me scratching my head.
