Sometimes yes — but many travel eSIM plans are data-only.
This is one of the biggest questions first-time travelers ask. People buy a travel eSIM expecting it to work like their normal SIM card, with calls, SMS, and mobile data included.
But many travel eSIM products are designed mainly for cheap mobile internet abroad, not traditional calling or texting.
This guide explains exactly can you use calls and texts with a travel eSIM, what kind of plans support it, and the smartest way to stay reachable while traveling.
Quick answer: Many travel eSIMs are data-only, meaning no normal calls or SMS. You can still use WhatsApp, FaceTime, Telegram, Messenger, and other internet calling apps. Some premium eSIM plans do include voice numbers and texting.
1. Most travel eSIMs focus on data
The most common travel eSIM model includes:
- mobile internet
- 4G / LTE / 5G data
- use of apps over data
But often does not include:
- traditional voice calls
- SMS texting
- local phone number
This keeps plans cheaper and simpler.
2. Yes — you can still call and message using apps
Even if the eSIM is data-only, you can usually use:
- WhatsApp calls
- FaceTime Audio / Video
- Telegram calls
- Messenger calls
- Zoom
- Teams
- Skype alternatives
For many travelers, this replaces normal calling completely.
3. Some travel eSIMs do include calls and SMS
Certain providers offer:
- local number included
- voice minutes

These are less common than data-only plans, but they exist.
4. Best travel setup: keep your main SIM + use eSIM for data
Many travelers use this smart dual SIM setup:
- Main SIM: home number for calls and SMS
- Travel eSIM: cheap mobile data abroad
This gives the best of both worlds.
