This article explains how to set up WiFi Calling on the Microsoft Lumia 640. Just follow the three simple steps below to get started.

1.            Connect your phone to WiFi

Can't find your WiFi network? Read our instructions on how to connect to a hidden WiFi network.

2.            Switch on WiFi Calling on your phone

Swipe left from the Home Screen and tap settings. Tap mobile + SIM. Tap SIM settings. WiFi Calling defaults as off. Slide the toggle to the right to turn on.

3.           Wait for your confirmation message

Once you’ve turned WiFi Calling on, we'll activate it for you within 24 hours. (If you are a corporate customer, you will not receive this message, as you’ll already be set up and ready to go).

You’ll receive a confirmation text when WiFi Calling has been activated. The WiFi Call indicator will appear at the top left corner of your screen. You’re now ready to send and receive calls and text over WiFi.         

A couple of things to note when using WiFi Calling

At launch, there are a couple of things which might make your call experience over WiFi Calling slightly unusual. Firstly, you’ll hear the international dialling tone when both parties are using WiFi Calling. Secondly, when a call is put on hold, the person on hold won’t hear the hold beeps. There will just be silence. We’re working to resolve these quirks, but it shouldn’t affect the quality of your service.

n.b. WiFi Calling is only available on the EE version of the Microsoft Lumia 640, bought directly from us in one of our stores, online at EE.co.uk, through our telesales team, or through corporate sales if you are a corporate customer.
