FREE CALLS TO FRIENDS ON NT CONNECT Unlimited voice calls with anyone else using the app, anywhere in the world, over Wi-Fi or mobile data.

RINGS LIKE A REAL CALL Incoming calls appear on your lock screen with your contact's name and show up in your phone's call log, right alongside your regular calls. REACHES YOU WHEN THE APP ISN'T OPEN Calls come through even when the app is in the background and your phone is asleep. Nothing to keep open, nothing to check. VISUAL VOICEMAIL See every voicemail in a list, play what you want, delete the rest. CALL FORWARDING Send calls to another number when you can't pick up. CALL BLOCKING AND SPAM PROTECTION Block unwanted numbers and manage your own allow and block lists. YOUR CONTACTS AND FAVORITES Call straight from your phone's contacts and keep the people you call most one tap away. BLUETOOTH READY Works with Bluetooth earbuds, headsets and car audio.
