Call anonymously where to find?

How can I call anonymously? My provider says it has to be on my phone, but where?
Can somebody help me?

Go to Phone
go to Settings (the three dots in the right-hand top of your screen)
go to Calling accounts
tap on your provider
go to GSM call settings
go to Additional settings
wait till the menu pops up
go to Caller ID
and choose ‘Hide number’


Just dial #31#phonenumber to suppress CLIR for exactly that call.
