Understanding WiFi Calling: What It Is and How It Works

WiFi calling is a feature that lets you make phone calls and send text messages using an internet connection instead of your mobile carrier's cellular network. When you have this feature turned on, your phone can connect to any WiFi network—at home, work, a coffee shop, or anywhere else with internet access—and use that connection to place calls and texts as if you were using regular cell service.

The technology behind WiFi calling converts your voice into data packets that travel over the internet, similar to how video calls or messaging apps work. Your phone automatically switches between WiFi calling and regular cellular calling depending on which connection is available and stronger. This means you don't have to manually choose which type of connection to use—your device handles it.

Most modern smartphones support WiFi calling, including devices running iOS 8 and later, Android 5.0 and later, and most Windows phones. However, not all carriers offer this feature, and some phones may have restrictions based on their manufacturer or carrier settings. The feature has been available since around 2015 and has become increasingly common as carriers recognize its value.

WiFi calling can be particularly useful in areas where cellular signal is weak but internet connection is strong. For example, if you're in a basement, rural area, or building with thick walls that block cell signals, WiFi calling may allow you to maintain phone service. It can also reduce data usage in some situations because voice calls use the internet connection rather than cellular airtime.

Practical Takeaway: Check your phone's settings to see if WiFi calling is supported. Look in your phone's "About" section or contact your carrier to learn whether your specific device and plan offer this feature.

Checking Whether Your Carrier and Phone Support WiFi Calling

Not all mobile carriers offer WiFi calling, so the first step is determining whether your carrier includes this feature. Major carriers in the United States—including Verizon, AT&T, T-Mobile, and most regional carriers—do offer WiFi calling to their customers. However, some smaller carriers, mobile virtual network operators (MVNOs), or prepaid services may not support it yet.

To find out if your carrier supports WiFi calling, visit your carrier's website or call their customer service number. You can usually find this number on your phone bill or on the back of your SIM card. When you contact them, explain that you want to learn about WiFi calling options. The representative can confirm whether your account plan includes this feature and whether any additional setup is required on their end.

Your phone also needs to support WiFi calling. Most phones made after 2015 have this capability built in, but older devices may not. To check your phone:

• On iPhone: Go to Settings, tap Phone, and look for a WiFi Calling option. If you see it, your phone supports the feature.
• On Android: Go to Settings, look for "Calls" or "Phone," and search for WiFi Calling. The exact menu varies by manufacturer.
• On other phones: Check your user manual or search for your phone model plus "WiFi calling support."

Keep in mind that having WiFi calling on your phone and having a carrier that supports it are two separate requirements. Both must be true for the feature to work. Some carriers may require you to meet certain account requirements, such as being a postpaid customer rather than a prepaid customer, though this is becoming less common.

Even if your primary carrier doesn't offer WiFi calling, you might be able to use WiFi calling through an alternative app-based service. Many messaging and calling apps—such as Skype, Google Voice, WhatsApp, or Viber—allow you to make calls over WiFi without needing carrier support.

Practical Takeaway: Contact your specific carrier directly to confirm whether WiFi calling is part of your plan. Write down the carrier's name, your account number, and the date you contacted them. Keep this information for your records.

Turning On WiFi Calling: Step-by-Step Instructions for Common Devices

Once you've confirmed that both your phone and carrier support WiFi calling, activating the feature typically takes just a few minutes. The process differs slightly depending on your device type, but the general principle is the same: navigate to your phone settings and toggle WiFi calling on.

For iPhone Users:

• Open the Settings app on your home screen.
• Tap "Phone" (not "WiFi").
• Look for the option labeled "WiFi Calling" or "WiFi Calling on Other Networks."
• Toggle the switch to the on position. The switch will turn green or blue when active.
• You may see a prompt asking for your emergency address. Enter this information if requested, as it helps emergency services locate you if you call 911 over WiFi.
• Confirm your selection and exit settings.

For Android Users (Samsung, Google Pixel, and similar):

• Open the Settings app.
• Look for "Connections," "Network & Internet," or "Phone" depending on your manufacturer.
• Find and tap "Calls" or "Call Settings."
• Select "WiFi Calling."
• Toggle WiFi Calling on if it's not already active.
• Enter or update your emergency address when prompted.

What Happens After You Enable It:

After turning on WiFi calling, your phone will begin searching for saved WiFi networks. When your device connects to WiFi, a small icon—typically showing a phone with WiFi waves—appears in your status bar. This indicates that WiFi calling is active and ready to use. Your phone will prioritize WiFi calling when WiFi is available and strong, but will automatically switch back to cellular calling when WiFi is unavailable.

Some carriers may require you to restart your phone after turning on WiFi calling for the first time. If calls don't work over WiFi immediately, try restarting your device and reconnecting to your WiFi network. If problems persist, contact your carrier to verify that WiFi calling is fully enabled on your account.

Practical Takeaway: After turning on WiFi calling, connect to your home WiFi network and make a test call to a friend or family member to confirm it's working properly. Note the icon that appears in your status bar so you recognize when WiFi calling is active.

Managing WiFi Calling Preferences and Advanced Settings

Beyond simply turning WiFi calling on or off, most phones and carriers offer additional settings that let you customize how the feature behaves. These preferences can improve your experience by giving you more control over when WiFi calling is used.

WiFi Preference Settings:

Most phones have an option to prefer WiFi calling when WiFi is available, or to prefer cellular calling even when WiFi is present. If you have a strong WiFi connection and want to conserve your cellular data, you can set your phone to prioritize WiFi calls. Conversely, if cellular service works well for you, you can set your phone to primarily use cellular and only switch to WiFi if cellular signal is very weak.

Emergency Address Updates:

When you enable WiFi calling, your phone may ask for an emergency address—the location where emergency services should respond if you call 911. This is important because 911 dispatchers may not be able to determine your exact location when you're calling over WiFi, unlike with cellular calls where location can be tracked more precisely. Most phones allow you to update this address in your WiFi calling settings. If you travel frequently or move, update your emergency address in your settings to reflect your current location.

WiFi Network Selection:

Your phone remembers WiFi networks you've connected to previously and may automatically connect to them when in range. You can view your list of saved WiFi networks in your phone's WiFi settings. Some people prefer to remove networks they no longer use to prevent automatic connections. Additionally, some carriers let you manage which networks your phone prioritizes for WiFi calling.
