Whitelist Call Blocker
Virus Free No Ads
By working with groups there are only a few clicks to block or allow hundreds of callers by Whitelist Call Blocker.
If the blocker is not working in most of the cases the local phone number format is the reason.
So if you want to get it fixed soon please send me the exact format of the number as it's to be seen in your display when somebody calls you. And tell me your country you are from. You can even write the numbers as an X (e.g. ++XXXX XXX XXX or XXX XX XXX X) Important for me are spaces and the non digits and the length.
Please report errors to firstname.lastname@example.org or on my facebook site at https://www.facebook.com/whitelistcallblocker
