Welcome to Android Central! Which phone and which carrier? Are you saying that you're not seeing the Caller ID of people calling you, or that other people don't get your Caller ID when you call them?
Be aware that this is an independent community forum, without any direct affiliation with Google or any other company, so there isn't anything we can directly do to restore your Caller ID.
