In today’s interconnected world, staying in touch with loved ones, colleagues, and clients while traveling abroad is crucial. With the rise of WiFi calling, many travelers are wondering if this technology will work overseas, allowing them to make voice and video calls using their smartphones. In this article, we’ll delve into the world of WiFi calling, exploring its capabilities, limitations, and what you need to know to stay connected while traveling abroad.
What is WiFi Calling?
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make voice and video calls using their smartphone’s internet connection. This technology uses the internet to transmit voice and video signals, rather than traditional cellular networks. WiFi calling is supported by many modern smartphones, including iPhones and Android devices.
How Does WiFi Calling Work?
WiFi calling works by using your smartphone’s internet connection to connect to a WiFi network. Once connected, your phone uses the internet to transmit voice and video signals to the recipient’s phone. This process is similar to making a voice or video call using a messaging app, such as WhatsApp or Skype.
To use WiFi calling, you’ll need:
- A smartphone that supports WiFi calling
- A stable internet connection (WiFi or mobile data)

What is WiFi calling and how does it work?
WiFi calling is a technology that allows users to make voice calls over the internet using a WiFi connection. It works by routing voice calls through the internet instead of traditional cellular networks. This means that as long as you have a stable WiFi connection, you can make calls to anyone, anywhere in the world, without relying on cellular coverage.
WiFi calling uses Voice over Internet Protocol (VoIP) technology to transmit voice calls over the internet. When you make a call using WiFi calling, your phone converts your voice into digital data and sends it over the internet to the recipient’s phone. The recipient’s phone then converts the digital data back into voice, allowing you to have a conversation in real-time.
Will WiFi calling work overseas?
Yes, WiFi calling can work overseas as long as you have a stable WiFi connection. Many countries have widespread WiFi coverage, and you can often find free or paid WiFi hotspots in public areas such as cafes, airports, and hotels. Additionally, many mobile carriers offer international WiFi calling plans that allow you to make calls over WiFi while abroad.
However, it’s essential to check with your mobile carrier before traveling abroad to see if they offer international WiFi calling and what the rates and coverage are like. Some carriers may charge extra for international WiFi calling, while others may include it in their standard plans. It’s also important to note that WiFi calling may not work in all countries or areas, so it’s always a good idea to check the local WiFi coverage before relying on it.
Do I need a special phone or plan to use WiFi calling overseas?
To use WiFi calling overseas, you’ll need a phone that supports WiFi calling and a mobile carrier that offers international WiFi calling. Most modern smartphones support WiFi calling, but it’s essential to check with your carrier to see if your phone is compatible with their WiFi calling service.
You may also need to add an international WiFi calling plan to your existing mobile plan. This can usually be done through your carrier’s website or by contacting their customer service. Some carriers may offer pay-as-you-go rates for international WiFi calling, while others may require you to add a monthly or annual plan.
How do I enable WiFi calling on my phone?
To enable WiFi calling on your phone, you’ll typically need to go to your phone’s settings menu and look for the WiFi calling option. This option is usually found in the “Connections” or “Wireless & networks” section of your phone’s settings. Once you’ve found the WiFi calling option, you can toggle it on to enable the service.
You may also need to enter your emergency address, as WiFi calling requires this information to work. This is a regulatory requirement in many countries, and it helps emergency services locate you in case of an emergency. Once you’ve enabled WiFi calling and entered your emergency address, you should be able to make calls over WiFi.
Is WiFi calling secure?
WiFi calling is generally considered to be secure, as long as you’re using a secure WiFi connection. When you make a call over WiFi, your voice is encrypted and transmitted over the internet, which makes it difficult for hackers to intercept your calls. However, if you’re using a public WiFi hotspot, there is a risk that hackers could intercept your calls if the hotspot is not secure.
To minimize this risk, it’s essential to use a secure WiFi connection whenever possible. Look for WiFi hotspots that use WPA2 encryption, and avoid using public WiFi hotspots that don’t require a password. You can also use a virtual private network (VPN) to encrypt your internet traffic and protect your calls from hackers.
Can I use WiFi calling to make emergency calls overseas?
Yes, you can use WiFi calling to make emergency calls overseas, but there are some limitations to be aware of. In the US, for example, WiFi calling is required to support emergency calling, including 911 calls. However, when you’re traveling abroad, the emergency calling features may not work in the same way.
When you make an emergency call over WiFi while abroad, your call may be routed to a local emergency service, but the service may not be able to locate you. This is because WiFi calling doesn’t provide the same location information as traditional cellular calling. To minimize this risk, it’s essential to know the local emergency numbers and to be prepared to provide your location information to the emergency services.
Are there any alternatives to WiFi calling for staying connected overseas?
Yes, there are several alternatives to WiFi calling for staying connected overseas. One option is to use a local SIM card or a prepaid international SIM card, which can provide you with a local phone number and access to local cellular networks. Another option is to use a messaging app, such as WhatsApp or Skype, which can allow you to make voice and video calls over the internet.
You can also use a portable WiFi hotspot, which can provide you with a secure and reliable WiFi connection wherever you go. These hotspots often come with international data plans, which can allow you to stay connected while abroad. Finally, you can use a traditional international calling card, which can provide you with a prepaid calling plan and access to local cellular networks.
