If you’re an iPhone 5s owner and you’re looking for a way to turn on wifi calling, there’s good news and bad news. The good news is that it’s easy to do; the bad news is that it’s not always reliable. Here’s how to do it:

  1. Open the Settings app on your iPhone 5s.
  2. Tap on Cellular and then tap on Wifi Calling.
  3. If wifi calling is turned off, tap on the switch next to it to turn it on. If wifi calling is already turned on, just tap on the blue dot next to Wifi Calling in order to configure it.
  4. You’ll now be able to choose whether or not you want calls made over wifi only, or if calls can also be made over cellular networks as well (assuming your phone has both options). Tap either option you want, then hit Done at the bottom of the screen when you’re finished configuring it. ..
