Travelers today have more ways than ever to stay connected abroad. Alongside eSIM technology, another feature that’s gained popularity is Wi-Fi Calling. But what exactly is it, and how does it work with your Roamvy eSIM? Let’s break it down in simple terms.

What is Wi-Fi Calling?

Wi-Fi Calling allows you to make and receive calls or send texts using a Wi-Fi connection instead of relying only on mobile networks.

It’s especially useful when:

• Mobile coverage is weak (hotels, basements, rural areas).
• You want to avoid international calling fees.
• You’re connected to a reliable Wi-Fi network.

How Does Wi-Fi Calling Work with an eSIM?

The process is simple:

1. Your phone connects to Wi-Fi.
2. Instead of routing calls over mobile towers, they travel over the internet.
3. On the other end, the call looks and sounds just like a normal phone call.

When combined with an eSIM for data, Wi-Fi Calling gives you multiple ways to stay connected while traveling:

• Use your Roamvy eSIM for mobile data on the go.
• Switch to Wi-Fi Calling when you’re in a café, hotel, or co-working space.

Benefits of Wi-Fi Calling for Travelers

• Lower costs: Avoid international call charges by using Wi-Fi.
• Better coverage indoors: Great for areas with weak mobile signal.
• No extra apps needed: Works directly with your phone’s dialer and messaging app.
• Seamless switching: Your phone automatically uses Wi-Fi Calling when available.

Do You Still Need an eSIM if You Use Wi-Fi Calling?

Yes. Wi-Fi Calling is a great complement, but not a replacement for mobile data. You’ll still need an eSIM for:

• Maps and navigation on the go.
• Ride-hailing apps like Uber or Lyft.
• Messaging apps outside Wi-Fi zones.
• Staying connected in transit (airports, trains, taxis).

FAQs

Do all phones support Wi-Fi Calling?
Most modern smartphones do, but you’ll need to check your settings to make sure it’s enabled.

Can I use Wi-Fi Calling without a SIM or eSIM?
No. Wi-Fi Calling still requires a SIM or eSIM to verify your number, even though it uses Wi-Fi for the connection.

Usually yes, but it depends on your home carrier. Using it with a Roamvy eSIM ensures you always have a reliable data backup.
