What number do I call for the operator on the 3 network service in the uk?

Answer 1

You can dial 118333 for national directory services or 118313 from your 3 phone for international directory services to help you find what you’re after. If you need the police you can dial 101 - the new non-emergency number. And if it’s serious you’ll always be able to dial 999, even if your keypad is locked.

This is from the three website - there was nothing specific about contacting an operator. Have you tried '100' or '0'?
