Do eSIMs Allow Calls and Texts?
One of the most common questions travelers ask is whether they can make calls and send text messages with Twise eSIM. The answer depends on which type of eSIM plan you choose. Many modern eSIM providers, including Twise, offer both data-only eSIMs and voice-enabled eSIM options. Each works differently, so understanding the difference helps you pick the right plan for your trip.
Most Twise travel eSIM plans are data-only packages. These are designed to give you fast, stable internet while abroad — without roaming fees or the hassle of buying a physical SIM card at the airport. Because these plans focus on data, you cannot make traditional phone calls or SMS directly from the eSIM line. Instead, you make calls and send messages through apps like WhatsApp, Messenger, FaceTime, Telegram, Skype, Viber, or iMessage. For most travelers, this is more than enough for staying in touch.
However, if you specifically want to make calls and send text messages with Twise eSIM using your phone’s normal dialer and SMS inbox, you can choose a voice-enabled eSIM plan. These plans include minutes and SMS capability, allowing you to call and text just like you would with a physical SIM card — as long as your eSIM is correctly installed and configured as your primary calling line.
How to Make Calls from eSIM (If Your Plan Supports It)
If you purchased a Twise plan that includes calling and texting features, here’s how to activate it properly:
1. Install the eSIM
Scan the QR code provided in your Twise confirmation email.
Follow the on-screen steps to add the eSIM to your device.
2. Set the Twise eSIM as Your Default Line
Go to your phone settings and select:
- Default line for calls
- Default line for SMS
- Default mobile data (if you want to combine voice + data)
This ensures your phone uses the Twise eSIM when you try to make calls and send text messages.
3. Make Sure You’re in Coverage
Voice-enabled eSIMs only work in the supported countries listed in your plan. Before traveling, check that your destination is included.
4. Dial With the Correct Country Code
This is a common mistake.
Always dial international numbers like:
- +1 for the U.S.
- +44 for the U.K.
- +82 for South Korea
Without the correct code, calls may fail even if your plan supports them.
How to Send Messages from eSIM
If Your Twise eSIM Includes SMS
You can send and receive texts normally. After setting your Twise eSIM as the default SMS line, just open your Messages app and text as usual.
If Your Twise eSIM Is Data-Only
You can still stay fully connected by using messaging apps that run on mobile data or Wi-Fi:
- iMessage
- Facebook Messenger
- Viber
- Line
- Telegram
This method avoids roaming SMS fees and works anywhere your data connection is stable.

What If My eSIM Is Data-Only?
If you choose a data-only plan, you can still make calls and send text messages — just not through the traditional cellular method. Instead, you use apps that rely on the internet.
You also have the option to keep your primary SIM active just for calls and SMS. Many travelers do this when they want to receive important verification codes or banking messages while abroad.
To avoid unexpected roaming fees:
- Turn OFF data roaming on your physical SIM.
- Leave call/SMS roaming ON if you still want to receive texts or calls.
- Use Twise eSIM for affordable mobile data.
- Use internet-based apps for communication.
This setup gives you the best of both worlds:
Reliable data + the ability to stay reachable on your original number.
