Who called from 4043876941

Caller ID: Unknown.

Doesn't the number need to be in your address book for a caller ID to come through on your cell phone?

Got text. No caller ID but message was pretty clear. Said that if I was still interested in finding a job to visit their website. Prolly got my resume off of Monster.

No, caller IDs are in the number programming. If it doesn't come up it's because there is none.

Cell phones are different than other phones. They want to limit the amount of data sent to keep costs down so they don't send caller ID info. The number has to be in your address book to come up in caller ID.
