What is WiFi Calling? WiFi Calling leverages WiFi to provide better mobile phone coverage by connecting calls over a WiFi network in places where cellular service is poor or non existent. Many major operators around the world provide WiFi Calling services, including Sprint, T-Mobile US, AT&T, Orange UK, Vodafone, Rogers Wireless in Canada, and Mobifone in Vietnam.

WiFi Calling is different from over the top (OTT) WiFi Calling applications because it is integrated with the phone. This means subscribers use their same phone number, native dialer, address book, etc. to make and receive calls over WiFi. OTT applications like Skype, Viber, and What’s App require users to create a new contact number that they will make and receive Wi-Fi calls from.

What is the Benefit of Wi-Fi Calling?

Have you ever been somewhere with little to no cellular coverage, but noticed there was WiFi access? WiFi Calling is a tool that lets you solve coverage problems. Certainly there are lots of places with great cellular coverage, but we all have that one corner of the building, or room in our house, where the coverage is spotty. With WiFi Calling, you can get your voice, messaging and other mobile services over WiFi in locations where you don’t have coverage.

How Does WiFi Calling Work?

WiFi Calling works on an enabled smart phone that is connected to a WiFi network. If your smartphone is set up to connect to the WiFi in your home or office, the WiFi Calling client will then automatically switch over to handle calls and messages over the Wi-Fi network (as opposed to the cellular network) whenever you enter your home or office WiFi range.

You can tell if WiFi Calling is active on your phone by an icon in the status bar and in the top right corner of the phone. For Sprint, it’s a white phone/spectrum symbol icon, T-Mobile, it’s a blue ‘Talk Bubble’, for Orange it’s a green house. Check with your network provider if you’re not sure what the icon should look like.

Naturally, the quickest way to tell if WiFi calling is working is if you are able to make a call or send a text from your cell phone in an area where you previously did not have cellular coverage.

Will Wi-Fi Calling Work In My Area?

If you can connect to a WiFi network, Wi-Fi Calling should work. Different operators have different configurations. Sprint and T-Mobile let users access WiFi Calling from just about anywhere in the world. Rogers and Orange UK limit people to domestic use (e.g. within Canada or the UK).

There have been reports of people using WiFi Calling from airplanes, when traveling internationally, from cruise ships, wherever there is WiFi. Users have tweeted and emailed to let us know they have used it from India, where the broadband is good, but the international rates are high. We have heard of people buying a pre-paid data SIM in Europe, putting it into a portable WiFi device, and using it to provide a personal WiFi hotspot to make cheap calls to the US.

How Are WiFi Calls Billed?

This is operator specific, and you should check with your operator about their service plan parameters. Here’s an example: Say you take your Sprint phone to France. You connect to WiFi Calling and call your friend in Seattle. The call is billed like a local call to Seattle (e.g. it comes out of your bucket of minutes), with no international roaming fees. However, if you’re in France and you call a French number (+33 …) then it’s billed like an international call to France.
