@JamesBond Hi there 👋 As we have a lot of under 18s on our network we need anyone who would like to remove the Adult Content Filter to provide photo ID and register their number. You'll find more details over on our How to turn off the Adult Content Filter blog 👌
For details on deactivating your voicemail take a look at All About: Voicemail , here you'll find the codes you need to use to stop your calls connecting to voicemail and also how to switch the diverts on again 😃
