Have gotten several calls, no message left.  Definitely junk call.

Stupid number keeps calling me and nothing on the other end

Keep getting multiple calls, usually around noon. I never answer, but they never leave a message.

I'm getting calls from this number stating Sierra Madre as area. I never answer. They leave no voice or text message. I just texted them saying, "Who are you?".  So far, no reply. But I did not receive a text saying it's a landline, so it must be a mobile phone, which is different. Most of these unknown calls come from landlines.

I'm starting to block all these callers.
