Can You Make Calls With an eSIM?

One of the most common questions travelers have when preparing for a trip is: Can you make calls with eSIM? The short answer is yes, but in a smarter way.

Our eSIMs are data-only, meaning you won’t get a temporary local phone number for SMS or analog calls. Instead, you can use your Unlimited Data to make crystal-clear voice and video calls through popular data calling apps like WhatsApp, FaceTime, or Messenger. It’s the modern way to stay connected without paying for expensive roaming minutes. Here is everything you need to know.

How Do Calls Work with a Data-Only eSIM?

It’s easier than it sounds. While traditional eSIM plans with call and text services rely on standard voice networks, a data-only eSIM works differently: all calls happen through the internet.

Instead of using analog minutes or a phone number, you make calls through internet-based apps. This way, you avoid expensive roaming charges and can keep communicating with friends and family seamlessly.

Ways to Make Calls When Using a Data-Only eSIM

There are two simple ways to make calls when traveling with your eSIM. You can rely entirely on apps, or keep your home SIM active for voice while using the eSIM for data. Both methods work. Keep reading to learn which one fits your trip best.

Using calling apps while traveling

This is the main way travelers make calls with a data-only eSIM. Apps like WhatsApp, Facebook Messenger, Telegram, and FaceTime let you place voice and video calls using only your mobile data. It allows you to talk without roaming fees, works worldwide, and is perfect if you already use these platforms for data calling every day.

Using your physical SIM for voice calls

Many people keep their personal SIM active for calls and SMS while using the travel eSIM for data. It’s an easy dual SIM setup, popular among travelers wondering how to call from an eSIM on iPhone or Android, and a convenient way to keep their usual number available.

Important: Just remember that your carrier may charge voice or SMS roaming fees, even if your primary SIM is not selected for Mobile Data. To avoid accidental data charges, keep data roaming disabled on your personal line and let the eSIM handle all your data usage during the trip.

Where App-Based Calling May Be Restricted

In some destinations, VoIP services like WhatsApp, FaceTime, Telegram, or Messenger may be partially restricted due to local regulations. This can affect voice or video calls even if your eSIM data works normally. These limitations are common in:

• China
• UAE/Dubai
• Oman
• Qatar
• Turkey (intermittent)

Some travelers use a VPN to restore calling features, but only where it is legal. Always check local regulations before using a VPN.

Troubleshooting Tips: 

If you are having trouble, try these quick fixes:

• Confirm your calling apps have permission to use mobile data. It's essential for data calling.
• If using Dual SIM, check that your physical SIM is set as the Default Voice Line for eSIM voice and data setups.
• Turn off Data Saver/Low Data Mode on your phone. It can restrict background data for calling apps and interfere with your eSIM calls.
• Restart your phone to refresh both lines.
• Test another app to see if the issue is with a specific service or your eSIM calls and data connection.
