In an increasingly connected world, staying in touch with loved ones, colleagues, and friends while traveling abroad can be a challenge. Traditional roaming options often come with hefty bill shock, making Wi-Fi calling an attractive alternative. But does Wi-Fi calling work abroad, and if so, how does it work?
Understanding Wi-Fi Calling
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), allows users to make and receive calls, send texts, and even access data using a Wi-Fi connection instead of traditional cellular networks. This technology has been around for several years, but its adoption has accelerated in recent times, thanks to the proliferation of Wi-Fi networks and the need for cost-effective communication options.
Wi-Fi calling works by routing your calls and texts through a Wi-Fi network, rather than relying on cellular towers. This means you can stay connected even in areas with weak or no cellular signal, as long as you have a stable Wi-Fi connection.
Wi-Fi Calling Abroad: The Good News
The good news is that Wi-Fi calling can work abroad, but it depends on several factors. Here are some key points to consider:

Wi-Fi calling requires a stable and fast Wi-Fi connection. This can be a challenge when traveling abroad, especially in areas with limited internet infrastructure. However, many airports, hotels, and cafes offer free or paid Wi-Fi services, making it easier to stay connected.
Wi-Fi Calling Abroad: The Challenges
While Wi-Fi calling offers a convenient way to stay connected abroad, there are some challenges to be aware of:
Quality of Service
Wi-Fi calling quality can vary greatly depending on the strength and stability of the Wi-Fi connection. In areas with high latency or packet loss, call quality may suffer, leading to dropped calls, echoes, or poor audio quality.
Data Roaming Charges
Even if you’re using Wi-Fi calling, you may still incur data roaming charges depending on your carrier’s policies and the country you’re visiting. Be sure to check with your carrier before traveling to understand any potential charges.
Emergency Services
Wi-Fi calling may not always provide access to emergency services, such as 911 in the United States. If you need to make an emergency call, you should use a traditional cellular connection or a local phone service.
Wi-Fi Calling Abroad: Tips and Tricks
To make the most of Wi-Fi calling while abroad, follow these tips:
Check Your Carrier’s International Wi-Fi Calling Policies
Before traveling, check with your carrier to understand their international Wi-Fi calling policies, including any restrictions, limitations, or additional fees.

Consider downloading apps like Skype, WhatsApp, or Google Voice, which offer Wi-Fi calling capabilities and can help you stay connected abroad.
Use Public Wi-Fi with Caution
When using public Wi-Fi networks, be cautious of potential security risks, such as man-in-the-middle attacks or data snooping. Use a virtual private network (VPN) to encrypt your data and protect your privacy.
Keep Your Device Charged
Wi-Fi calling can drain your device’s battery faster than traditional cellular connections. Keep your device charged and consider packing a portable power bank to stay connected on the go.
Wi-Fi Calling Abroad: The Future
As Wi-Fi calling technology continues to evolve, we can expect to see improvements in call quality, expanded international coverage, and more carrier support. The increasing adoption of 5G networks may also lead to faster and more reliable Wi-Fi calling experiences.
In the meantime, by understanding the benefits and challenges of Wi-Fi calling abroad, you can stay connected with loved ones, colleagues, and friends while traveling abroad – without breaking the bank.

What is Wi-Fi calling?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a technology that allows users to make phone calls using a Wi-Fi internet connection. This feature is usually available on smartphones and allows users to make and receive calls over a wireless network instead of using traditional cellular networks.
Wi-Fi calling is different from traditional voice calls, which rely on cellular networks to connect calls. With Wi-Fi calling, your phone connects to a nearby Wi-Fi network, and your call is routed through the internet. This can be especially useful in areas with poor cellular coverage, such as rural areas or indoors with thick walls.
Do all smartphones support Wi-Fi calling?
Not all smartphones support Wi-Fi calling, but most modern devices do. Typically, smartphones running on iOS 9 or later, Android 6.0 or later, and Windows 10 or later support Wi-Fi calling. However, it’s essential to check with your device manufacturer or service provider to confirm whether your specific phone model supports Wi-Fi calling.
Even if your phone supports Wi-Fi calling, your service provider may not offer this feature. Some carriers may require you to activate Wi-Fi calling on your account or may have specific plans that include this feature. So, it’s crucial to check with your service provider to see if they offer Wi-Fi calling and what the requirements are.
Can I use Wi-Fi calling abroad?
Yes, you can use Wi-Fi calling abroad, but there are some limitations and potential issues to be aware of. If you have a phone that supports Wi-Fi calling and you’re traveling to a country with Wi-Fi availability, you can make calls using a local Wi-Fi network.
However, you’ll need to ensure that your phone is set up to use Wi-Fi calling, and you may need to activate international Wi-Fi calling on your account with your service provider. Additionally, the quality of the call may vary depending on the strength and stability of the Wi-Fi network you’re connected to. Be aware that some countries may have restrictions on VoWi-Fi, so it’s a good idea to check local regulations before using this feature.
Will I be charged for Wi-Fi calling?
Wi-Fi calling rates vary depending on your service provider and the country you’re in. In some cases, Wi-Fi calling may be included in your existing plan, while in others, you may be charged per minute or per call.
It’s essential to check with your service provider to understand their Wi-Fi calling rates and policies, especially when traveling abroad.
