All calls to me are now showing as "unknown"

[imjs]

I'd been wondering why I was missing calls from my family despite having their number set to override the DND on my phone. I've realised that suddenly all calls are coming through to my phone without the caller ID. I have tried 3 family members on 3 networks (one is Smarty) but they are all showing up as "unknown caller". I can see them in my contacts list (android/google). Any idea what's changed, please?

@imjs  A quick Google search suggests that your phone is not receiving the caller ID with each call.

I would advise a web chat with Smarty Support team so that they can check your account. Also worth checking if it's the same with your sim in another phone first if possible.
