Secure Numbers Only

Secure Numbers Only (SNO) is the way to TAKE BACK YOUR PRIVACY. SNO is a call blocker and instantly blocks numbers that are not in your contact list. The app also has a built-in feature that sends an automated sms to the caller. The sms has a request form link that the caller needs to fill out and submit to contact the user. You choose who is allowed to contact you by approving or blocking the request on the app. The app also has a built-in group function, where you can add people or children and monitor who is on their contact list and who is trying to contact them. - TAKE BACK YOUR PRIVACY WITH SNO - NO SPAMCALLERS - NO ROBOCALLS - PROTECT YOUR FAMILY AND TAKE BACK CONTROL EMERGENCY NUMBERS: For emergency numbers to be able to contact you please ensure that you add them to your contact list. NOTE: For successful call blocking, the app needs to be set as the default dialer, or default caller ID and spam app. This can be changed in the default apps section of your device's settings.
