Someone is call my cell private how can I get the number

You can try Trapcall service for your phone. It is not free though; plans cost from $5 per month up to $25 per month depending on the features you want. There is no annual contract, but the plans are discounted if you opt for a 6 month or 12 month plan.

I think the service was originally developed to help protect abused women and has expanded from there.
