This feature could help you to save on the SMS cost by not triggering the SMS verification for a known blacklisted phone number. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, an error message about the blacklisted phone number will be returned. You will have to create your blacklisted phone number list for this feature to function. Please read this <a href=\"https:\/\/www.fraudlabspro.com\/resources\/tutorials\/how-to-blacklist-a-phone-number\">article<\/a> on how to do so. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once you are done with the blacklisted phone list update, you can enable the feature by following the below steps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1.
