This is how Truecaller caller ID works on iPhone. It works a bit differently than it does on Android due to Apple restrictions but the iPhone user does need to have a 3g, 4g or a strong Wi-Fi connection and they also have to have the Truecaller app installed. With the Android here, we’re going to show you how to call You don’t have to call using Truecaller, you can use the normal dialer but we’re going to be calling from Truecaller. so the iPhone does NOT have the Android’s number in their phonebook so this will be a totally new number for the iPhone. So what happens when you call… You’re going to get a push notification with the name and now you’re going to get the ID of the caller.
