How to Enable WiFi Calling

Last Updated:

If you know how to enable WiFi calling, you can make voice calls over a WiFi network instead of using your cellular company's mobile network. But why would you want to do that?

Voice calls can be made using your home WiFi connection or a WiFi hotspot when you are out and about. They can be a handy calling option when you are in an area with weak or no cellular coverage, which I'm sure we have all experienced before (like on an airplane).

Typically, WiFi calls are SIMilar to normal phone calls, using regular phone numbers. The four major wireless carriers, T-Mobile, Verizon Wireless, Sprint and AT&T, each offer their own version of WiFi calling.

WiFi call services are fairly easy to set up from your phone settings, with minor differences depending on your cell phone carrier. You'll need to check if your carrier offers WiFi calling with the phone you have. It is also important to check your wireless carrier's billing policy for WiFi calls on your service plan.

What is WiFi Calling?

This is how it works. WiFi call services allow you to make a phone call via WiFi instead of via cellular signal. To use WiFi calling, you need to find a hotspot or WiFi connection. You can go to a cafe, a library, or use a separate hotspot to make WiFi phone calls.

One great thing about WiFi calling is that it can be used while your phone is in airplane mode. In airplane mode, your phone still has access to WiFi. As a result, you can make business phone calls and send messages via your WiFi hotspot or your plane's WiFi connection.

WiFi calling has been with us for awhile, with device and phone apps like Skype, Google Hangouts, and Google Voice. Such phone apps allow users to make and receive phone calls and text messages over the internet, even if they don't have a cellular network connection.

WhatsApp is another fantastic WiFi call app, letting you make calls and send texts for free, even if you don't have a cellular coverage plan. It's available on a wide range of smartphone devices, all you need is access to a wireless network. You can even use WhatsApp on your iPod Touch or iPad.

If you have a prepaid device, you can also buy a SIM card for WiFi calling. Once you buy a SIM card, insert it into your phone to use it for WiFi calls and texts. Even if you don't have a prepaid device, you can download a SIM VoIP app for WiFi calling.

One advantage of using your cell phone plan's WiFi service over the free WiFi calling apps is that they offer 911 emergency access, while the free Apps do not offer the ability to make emergency calls.

How to Enable iPhone WiFi Calling

If you're an iPad or iPhone user, there are a couple of different ways you may be able to call someone via WiFi. Many iPhone iterations, such as the iPod Touch, have actually had WiFi calling capabilities in the name of FaceTime for years. Facetime allows iCloud users to sign into their iCloud account and chat with one another over WiFi. If you are not an iCloud user, however, your iPhone may also be able to make WiFi calls without using an iCloud account via FaceTime, as long as your carrier allows it.

If your carrier supports WiFi calling, here's how to enable WiFi calling on your iPhone:

1. Open the Settings, then tap on Phone.

2. From there, scroll to WiFi Calling.

3. Switch the slider on and follow the on-screen prompts showing you how to enable WiFi calling.

From Settings > Phone > WiFi Calling, you can turn on this call feature. If prompted, enter or confirm your address in case of emergency. The status bar will then display WiFi after your carrier name. Once the status bar does this, you can proceed to make a call and text via WiFi.

Voice Over LTE

You may also be able to turn on Voice Over LTE calls. LTE Voice Over calling is an upgrade from your wireless service that allows you to make calls and send messages over your LTE network instead of over other, more congested networks. Voice Over LTE calling requires a certain smartphone hardware in order to work properly. Additionally, both users need to have their VoLTE option turned on in their settings for it to work. Your phone's LTE Voice Over capabilities will also depend on what each cellular carrier allows. Call your cell phone carrier support number for more information.

If you don't see WiFi calling as an option, it's possible it's at a different location in your interface. Search the name of your smartphone model and "WiFi calling" as well as the name of your cellular service provider.

Pro Tip: WiFi calling support is not available on some phones. The service must be offered by your cellular network provider.

Verizon Wireless WiFi Calling

Here are some tips on activating WiFi calling with Verizon Wireless. Be sure you have access to the internet to complete the setup.

First, you need to activate HD Voice, which is called "Advanced Calling" on some phones. You also must set up an address to use in case of emergency.

Check to see if your device is HD Voice enabled and that your account includes the HD Voice feature. Activate HD Voice (skip this step if it's activated already). Go to the Apps menu from your home screen, and tap Settings, then tap Advanced Calling > Activate Advanced Calling. Follow any onscreen instructions to enter an address in case of emergency. When the address is entered, you're ready to make WiFi calls.

AT&T WiFi Calling

AT&T customers can use WiFi calling and text whenever they have access to a WiFi connection. It's especially good for those indoor locations where the cellular signals can't reach, but a wireless network connection is available. You can use this feature in the U.S. as well as most international locations. It's easy to set up and once enabled it works automatically.

To enable WiFi calling for AT&T customers, open your iPhone's settings and follow the steps to activate WiFi calling.

Make and receive phone calls domestically at no additional charge and no impact on your airtime usage via WiFi. Text messages over WiFi are charged as per your current rate plan. Note that for international calls, your calling plan rates will apply even when you call via WiFi.

T-Mobile WiFi Calling

T-Mobile offers WiFi calling, access to high-speed data and instant messaging over wireless internet connections. The first step is to check that your T-Mobile iPhone or Android device supports WiFi calling. Then the feature must be enabled in settings. Get information on how to set up your T-mobile iPhone or Android for WiFi calling on the T-Mobile WiFi calling Device tutorials page.

For the most part, it's a matter of going to settings, tapping WiFi calling, and following the prompts to activate the service.

You are also required to set up a 911 emergency service address so your location is available to the dispatcher in case of any emergency calls or necessary emergency services. Visit the T-Mobile instructions page for setting up your e911 address.

Pro Tip: When making WiFi calls over T-Mobile, be sure to disable data roaming especially when traveling internationally to avoid data roaming charges. We have a guide on how to avoid data roaming charges for you.

Sprint WiFi Calling

WiFi Calling with Sprint can be activated with both Android smartphones and iPhones. It's a great way to improve voice service in an area with limited mobile network coverage, again you must have access to WiFi to use the feature.

Sprint iPhone users need iOS 8.3 or later. With your iPhone, go to settings and tap Phone. Tap WiFi calling to turn on the option and follow the prompts.

Sprint Android phone users can turn on the option from WiFi calling inside settings, following the on-screen prompts.

You can use WiFi calling over the Internet in over 200 countries, but international calling rates still apply.

If you use apps like Skype, Google Hangouts, Google Voice and WhatsApp to make WiFi calls, and you also have a cellular service provider plan, you may still be charged for using data during calls, unless you make a point of turning data off while using these apps.
