Wi-Fi calling FAQs

Learn about the basics of Wi-Fi calling with answers to frequently asked questions:

What is Wi-Fi calling?

Wi-Fi calling allows you to make phone calls and send texts over a Wi-Fi connection rather than through your phone carrier's cellular network.

Why would I use Wi-Fi calling?

There are several advantages to Wi-Fi calling over standard calling:

• Wi-Fi calls use something called a High-Definition (HD) Voice service, which typically makes the call quality clearer.
• If you're in an area where cellular service is spotty, Wi-Fi calls can sometimes keep calls from getting disconnected.
• Your Wi-Fi connection doesn't need to be extremely fast to support a Wi-Fi call. Most internet speeds are capable - 1Mbps should be enough.

How do I know if I can use Wi-Fi calling?

All major cellular carriers - AT&T, Verizon, Sprint, and T-Mobile - support Wi-Fi calling on recent iPhone and Android smartphone models.

Is Wi-Fi calling free?

For the most part, Wi-Fi calling is free, as long as the calls are being made to US numbers. In some cases, you may need an unlimited plan to access free Wi-Fi calling.

For more information, check your carrier's Wi-Fi calling rates and policies:

• AT&T
• Verizon
• Sprint
• T-Mobile

Are there any downsides to Wi-Fi calling?

When you make Wi-Fi calls internationally, you will be charged based on your international calling plan, so be sure to double-check your rates before racking up extra costs.

If you're traveling abroad and want to make calls, it's safest to use a third-party app like WhatsApp rather than worry about incurring any international calling fees from your carrier.
