Benefits of using WhatsApp with an eSIM

With your Free Roaming eSIM, you can use WhatsApp just as you normally would during international travel. There’s no need to change your number or worry about roaming fees. As long as you have an internet connection, you’ll stay in touch from anywhere in the world.

Make international calls and send messages without extra charges, since it works over mobile data.
Keep your main WhatsApp number active, no matter where you are, there’s no need to add a local number.
With an eSIM, you don’t need a physical SIM card. Just mobile data or Wi-Fi is enough to stay connected.

Things to Keep in Mind

Make sure WhatsApp is allowed to use mobile data on your phone. If it’s not set up correctly, it won’t work—even with an eSIM.
To make or receive WhatsApp calls or send and receive messages, the other person must also have the app installed and be connected to the internet.
To avoid roaming charges from your primary carrier, turn off your main SIM while using your Free Roaming eSIM.
If you’re traveling to countries like China, keep in mind that WhatsApp may be blocked due to local internet restrictions, even with a VPN.
