What about the television adverts for chastise that say �Text nnnnnn to donate £x�, either once-off or monthly.

That will charge your mobile account. So anyone knowing your number could presumably pull off the same trick?

You need the phone though to be able to send the text from it. Unless it is done purely on CLI and someone spoofs the number - but I don't know if it uses CLI for identity or if it uses something else like the IMEI.

In reply to a post by RobertoS:

Your previous post contradicts that assertion .
