If I've never provided the NHS with my mobile phone number and yet still received this text am I correct in assuming it was either sent by BT themselves or that they provided whoever sent it with all of their customers' numbers?
It would have been sent by all mobile operators to all their numbers registered on their customer database. I think there is a facility called cell broadcast, which is also used for emergency alerts. They do not need any personal details to do this.
