Now that's the sort of thing I was afraid of. This person is said to have handed his phone briefly to the complainant (long enough to clock and record the number, or even send it to her own phone). What made me wonder is that she's made this complaint before about others (which smelt faintly ratty to me.)

I'll test it on my spare sim card and my NHS number, I think. That would just leave the question whether that site is accessible from an NHS pc.

Edit: Costs £5 to pick up the text, and I don't think the NHS would like me dumping that on their bill! OTOH, it would be a small price to pay to get someone you don't like into trouble!
