International WiFi Calling: Is it Free?

WiFi calling is a feature built into most cellular devices that allows you to make and receive calls and texts over WiFi. It’s really handy when cellular service is unavailable or unreliable.

You can stay in touch with those who matter, even with those who live internationally, almost anywhere a WiFi connection is available. Calling the US from home or abroad is free, but what about international WiFi calling?

Is International WiFi Calling Free?

Since it’s free to use WiFi calling for domestic communication, many people assume the same applies when calling or texting long-distance numbers. Unfortunately, that is not the case. Per the three major US carriers’ WiFi calling terms, calling or texting international numbers over WiFi can result in additional charges. Rates will vary across carriers and countries.

AT&T International WiFi Calling Rates

WiFi Calling Other Countries From the US

Most of AT&T's plans include texting to 200+ countries at no charge. You don’t have to worry about being charged for sending texts over WiFi. However, when calling internationally over WiFi from AT&T's Domestic Coverage Area (DCA), which includes the US, Puerto Rico, and the US Virgin Islands, international long-distance rates apply. They are charged per minute and rounded up to the nearest minute.

WiFi Calling Other Countries When Abroad

WiFi calling charges to countries outside of AT&T's DCA depend on your international roaming add-ons.

International roaming add-ons include:

  • AT&T International Day Pass ($10/day): Fee includes WiFi calling to over 210 destinations. If WiFi calling a country not included in the International Day Pass, you will be billed pay-per-use rates.
  • AT&T Cruise Package ($100 or $60 for 30 days): WiFi calling is included in package allowance. Rates will apply after allowance has been reached.
  • Pay-Per-Use: If you do not have an international roaming add-on, WiFi calls to international numbers will be charged a per-minute rate.

T-Mobile International WiFi Calling Rates

WiFi Calling Other Countries From the US

WiFi calls placed to other countries from the US are subject to your plan’s long-distance charges. You can take a look at T-Mobile's stateside international rates for long-distance fees.

If you have T-Mobile's Stateside International Talk add-on ($15/mo), which includes calls from the US to landlines in 70+ countries and mobile lines in 30+ countries as well as discounted rates to the rest of the world, WiFi calling is not supported. It only covers calls made over cellular. WiFi calls will be charged at the international rate.

Sending texts over WiFi calling to international numbers is also subject to your plans long distance charges. However, most plans activated after November 2015 include unlimited texting to anywhere text is available. Thus, you shouldn’t be billed for texting over WiFi if you have a compatible plan.

WiFi Calling Other Countries When Abroad

For those who have an unlimited T-Mobile plan:

  • WiFi calls cost $0.25/min when in 215+ countries and destinations.
  • WiFi calls are charged at World Class rates when on a cruise ship/ferry network, airline (in-flight) network, or countries not included in the 215+ list. You can check rates here, in the “Which country or destination are you traveling to?” section.
  • Messages over WiFi are included when in 215+ countries and destinations.
  • Messages over WiFi cost $0.50 when on a cruise ship/ferry network, airline (in-flight) network, or countries not included in the 215+ list.

Those without unlimited plans are subject to World Class rates when calling other countries while aboard.

Verizon International WiFi Calling Rates

Verizon’s international WiFi calling charges are very vague. They state:

WiFi Calling Other Countries From the US

Charges are based on your international long-distance calling plan. Pay-as-you-go rates apply if you do not have one.

WiFi Calling Other Countries When Abroad

Charges are based on your international long-distance calling plan. Pay-as-you-go rates apply if you do not have one.

  • Connect your iPhone to a WiFi network.
  • Go to Settings.
  • Tap Phone.
  • Toggle On.
  • Tap Enable.
For Android:
