Re: What a surprise - TPS is useless.
Be VERY wary giving out your mobile number.
Not that wary. I just have an old phone with a 3 PAYG SIM in it stuck away in a drawer. (FYI 3 credit rolls over month after month). Just turn it on and use it once a quarter or thereabouts, otherwise it's off
That way I am certain I'll be giving out a number that's highly unlikely to be superceded and that I have little concern about who knows.
Handy standby too
