Why Should You Choose Dualine
Dualine gives you a second line for calling, texting, and picture messaging. It intercepts calls on your Dualine second number, routing them to your cell phone so no one sees your real number. You can call, text, and manage contacts from within the app and treat it as a long-term second phone number or create a disposable phone number for dating, food delivery apps, Uber, Lyft, online shopping, or selling items in Facebook Marketplace in order to protect your identity and phone number from would-be stalkers.
