Sometimes yes, but in many cases travel eSIMs are data-only.
That means many travel eSIM plans are designed mainly for mobile internet, not for traditional voice calls or SMS. This is one of the most common things travelers want to understand before buying.
This guide explains whether you can call and text with a travel eSIM, when a travel eSIM includes a phone number, and the best way to stay connected while abroad.
Quick answer: Many travel eSIMs are data-only, so they do not include traditional calls or SMS. However, you can still use apps like WhatsApp, FaceTime, Telegram, and Messenger, and many travelers keep their regular SIM active for calls and text messages.
What does data-only mean?
A data-only travel eSIM gives you mobile internet access but does not always include:
- a local phone number
- traditional voice calls
- standard SMS text messaging
This setup is very common because many travelers mainly need internet for maps, messaging apps, rides, bookings, and web browsing.
Can I still make calls with a travel eSIM?
Yes, in many cases you can still make calls, but often through internet-based apps rather than normal carrier voice service.
For example, with mobile data from a travel eSIM, you can usually call using:
- FaceTime Audio
- Telegram
- Messenger
- Zoom or similar apps
So even if your eSIM is data-only, you may still be able to communicate very easily.
Can I send text messages with a travel eSIM?
It depends on what you mean by text messages.
If you mean traditional SMS, many travel eSIMs do not include that.
If you mean internet messaging apps, then yes — in most cases you can send messages normally through apps like:
- iMessage
- Telegram
- Messenger
- Viber
As long as your eSIM provides working mobile data, those apps usually continue working.
Do travel eSIMs come with a phone number?
Some do, but many do not.
Many travel eSIM plans are sold only for data, which means they are not designed to replace your main phone number. Instead, they are designed to give you internet access abroad quickly and easily.
That is why it is important to check the plan details before buying if traditional calls or SMS matter to you.
What is the best setup for most travelers?
For many people, the best setup is simple:
| Line | Recommended Use |
|---|---|
| Main SIM | Calls, SMS, verification codes |
| Travel eSIM | Mobile data abroad |
This setup lets you keep your normal number while using the eSIM for data.
Will WhatsApp still work with a travel eSIM?
Yes, in most cases WhatsApp will still work normally.
WhatsApp is linked to your phone number, but it works through an internet connection. That means your travel eSIM can provide the data while your WhatsApp account stays the same.
This is one reason many travelers are happy with a data-only eSIM.
Can I still receive SMS on my main number?
Usually yes, if your main physical SIM stays active in the phone and your carrier supports service while abroad.
This can be useful for:
- bank codes
- two-factor authentication
- booking confirmations
- important account alerts

What if I want regular calls and SMS too?
If you want traditional calls and SMS, you have a few options:
- keep your main SIM active for calls and texts
- choose a plan that specifically includes a phone number
- use internet calling and messaging apps instead
For many travelers, keeping the main SIM active is the easiest solution.
Does iPhone or Samsung handle this differently?
The idea is similar on both. If your phone supports dual SIM, you can often keep your main SIM for calls and texts while using the eSIM for mobile data.
Common mistakes to avoid
Assuming every travel eSIM includes a phone number
Many travel eSIMs are data-only, so always check the plan details.
Confusing app messaging with SMS
WhatsApp and similar apps use data, not standard SMS service.
Turning off the main SIM too quickly
If you want calls or verification texts, keeping your regular SIM active may be the better option.
Expecting normal calls without checking the plan
If voice service matters to you, confirm it before buying.
Final thoughts
Yes, you may be able to call and text with a travel eSIM, but in many cases this happens through internet apps rather than traditional carrier voice and SMS.
For most travelers, a data-only eSIM plus an active main SIM is the easiest and most flexible setup.
