When you receive a call to your Burner, it is routed through your actual phone number and will show up as your Burner number calling you. However you can receive a notification that tells you when a number is calling and who it is before the Burner number is shown as calling you.
On an iPhone: Set Push Notifications to “On;” you will receive a notification before you get the call from your Burner. The notification alerts you as to who is calling.
On Android: Make sure “Rings,” underneath your Burner number, is set to on. This way you will be notified and can get a call. “Rings” is found in the “More Options” on the bottom bar; it is the last icon on the bar. Make sure that when the menu is open it says “Disable Rings,” which in turn, means that “Rings” is on.
