Safe Talk is a new service in the UK that allows you to generate a temporary phone number to use for 7 days to give to people you don't trust/know.

It's simple - text CALL to 80876 and get a temporary number that diverts to your mobile phone for 7 days, and keep your own number safe - until you know if they're nuts or not!

Each number costs £1.50, and you can choose to either extend your usage of the number after seven days or cancel it.
