On outgoing calls from your Numero line, you can flip on per-call privacy that displays &#8220;Unknown Number&#8221; or a different number to the receiver. This is the in-app equivalent of Method 1, layered on top of an already-not-your-primary line.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">That last layer is what most articles miss.
