Hiya @JennyL, thanks for getting in touch. I'm really sorry that the caller display isn't working, it does look like this just isn't active on our back end systems.
I have now placed an order to add this for you and it should be active within the next working day. Should you have any further queries at all, please do not hesitate to get back to me.
