I can confirm it does have the WIFI Calling feature. I've used it a few times so far without any issues. Yes this phone has Wi-Fi Calling installed. It certainly does, but please be advised that this feature often needs to be activated on your account by your network provider before it appears on the phone, so we would speak to them as well to ask what is required to do this. We hope this helps! ^DB at Samsung Support Yes Yes it does####[]
