Voicemail Caller

[Alie57]

Hi 

I've received a couple of voicemail messages, but the caller didn't leave their no. How can I find out who has called me, please.

Is the call not in your call logs?
Sometimes one of the options after listening to the message is "details" - this should include the number that called you.

@Alie57 If the number hasn't appeared in your caller display there's no way you can tell. Chances are they are scam calls, so it's best to ignore them.

Ok thanks a lot. I didn't ring them back, so hopefully they will just get sick of me.
