Wi-Fi calling lets you make and receive calls and texts over a Wi-Fi connection instead of the cellular network. This is a game-changer if you have poor cell signal at home, work, or anywhere your carrier’s network is weak. This guide explains how Wi-Fi calling works, which carriers support it, and how to set it up on Android and iPhone.
What Is Wi-Fi Calling?
Wi-Fi calling is a feature built into most modern smartphones and supported by major US carriers. When enabled, your phone routes calls and text messages through your Wi-Fi internet connection when cellular signal is weak or unavailable. Calls sound just like regular phone calls, and they show up on your phone bill normally — there is no extra charge in most cases.
Which Carriers Support Wi-Fi Calling?
Most major and prepaid carriers in the US support Wi-Fi calling, including AT&T, T-Mobile, Verizon, Metro by T-Mobile, Cricket Wireless, Boost Mobile, Consumer Cellular, Mint Mobile, Visible, and many others. Check your carrier’s website or call customer service to confirm Wi-Fi calling is supported on your specific plan.
How to Enable Wi-Fi Calling on iPhone
- Open Settings on your iPhone.
- Tap Cellular (or Phone on older iOS versions).
- Tap Wi-Fi Calling.
- Toggle on Wi-Fi Calling on This iPhone.
- You may be prompted to enter or confirm your address for emergency services (E911). This is required by law.

When Wi-Fi calling is active, you will see “Wi-Fi” next to your carrier name in the status bar at the top of the screen.

Other Android Phones
The location of the Wi-Fi calling setting varies by manufacturer. Try searching for “Wi-Fi calling” in your Settings search bar, or look under Settings > Network & Internet > Mobile Network > Wi-Fi Calling.
Wi-Fi Calling Not Showing Up?
If you cannot find the Wi-Fi calling option, there are several possible reasons:
- Your carrier does not support Wi-Fi calling on your specific plan or device. Contact your carrier to confirm.
- Your phone is locked to another carrier. If you are using a phone originally purchased from a different carrier, it may block Wi-Fi calling on your current carrier’s network.
- Your phone is too old. Wi-Fi calling requires VoLTE (Voice over LTE) support, which is not available on very old devices.
- VoLTE is not enabled. On some phones, Wi-Fi calling requires VoLTE to be turned on first. Check Settings > Mobile Networks and look for a VoLTE option.

Frequently Asked Questions
Does Wi-Fi calling use data?
Wi-Fi calling uses your Wi-Fi internet connection, not your cellular data plan. It does not count against your monthly data allowance. However, it does use your home internet bandwidth — typically about 1 MB per minute for a voice call.
Is Wi-Fi calling free?
Wi-Fi calling itself is free on most carrier plans in the US. Calls to US numbers are treated the same as regular cellular calls and use your included minutes. Calls to international numbers may incur international calling charges depending on your plan.
Can I use Wi-Fi calling without a SIM card?
No. Wi-Fi calling is a carrier service tied to your phone number, which is associated with your SIM card. You need an active SIM card and a carrier plan that supports Wi-Fi calling. Without a SIM, you can use apps like WhatsApp or FaceTime for calls over Wi-Fi, but these are not the same as traditional Wi-Fi calling.
Does Wi-Fi calling work for emergency 911 calls?
Yes, Wi-Fi calling supports 911 calls. That is why carriers require you to register your address when enabling Wi-Fi calling — so emergency services can locate you even when you are calling over Wi-Fi from a registered address rather than a cell tower.
