There are many smartphone apps out there that will answer your smartphone when a spam caller calls. The downside is that you have to have the smartphone on and it can be a drain on your battery. We put a Bluetooth number detector on our website that you can use for free. If you are using a smartphone, use our app as it will work in the background to stop spam calls from being forwarded to you. For both android and iPhone users, we have an app available in the Google Play Store and Apple's App Store to configure your smartphone to forward unwanted calls (upper right-hand corner of this page) forward to our caller ID detectors so you know right away if there are any unwanted sales callers or nasty spammers on the line
