Call waiting not working

[Jessnoone]

The call waiting won’t activate on my iPhone 12. Every time I go to select it says could not save. Without this I don’t have voicemail either. Please help

Hi @Jessnoone

Thanks for coming to the community. 

Have you tries restarting your iPhone and trying to activate call waiting again? 

Have you text VM ON to 150? 

Thanks 🙂

Leanne.
