Do eSIMs include calls and SMS? A travel calling guide
An eSIM can make calls and send texts, but only when the mobile plan installed on it includes voice and SMS. The eSIM itself is a digital SIM format. Most short-term travel eSIMs focus on data, so app calls work while normal phone calls and carrier SMS may not.
Check the package type before buying. If the listing says "data only," do not expect a new phone number, calling minutes, or SMS. If it says "data, voice and text," read which countries you can call, what number you receive, and how many minutes or messages are included.
Quick answer: what works with each eSIM setup?
The word "eSIM" tells you how the mobile plan is installed, not which services the plan includes. A carrier can put a full phone plan or a data-only travel plan on the same eSIM chip.
| Setup | Normal calls | Carrier SMS | Internet calls and messages | Phone number |
|---|---|---|---|---|
| Data-only travel eSIM | No | No | Yes, through apps using data | Usually none |
| Travel eSIM with voice and SMS | Yes, within the plan's rules | Yes, within the plan's rules | Yes | Usually included |
| Home SIM plus data-only travel eSIM | Through the home line if roaming is available | Through the home line if roaming is available | Yes, through travel data | Your existing number stays on the home line |
| Local carrier eSIM | Usually, when included in the local plan | Usually, when included in the local plan | Yes | Often a local number |
This distinction matters at checkout. A large data allowance does not imply voice minutes, and an unlimited-data label does not mean unlimited calls or texts.
What is the difference between an eSIM and an eSIM plan?
An eSIM is the digital version of the SIM profile that authenticates your phone on a mobile network. The plan attached to that profile decides whether you receive data, voice service, SMS, or a combination of them.
The GSMA's eSIM overview explains that eSIM changes how a SIM profile is loaded into the device. It does not change the SIM's role. This is why a full carrier plan on an eSIM can behave much like the same plan on a removable SIM card.
Travel sellers often use "eSIM" as shorthand for a prepaid data package. That is common, but it can make data-only plans sound like a limitation of the technology. It is a limitation of that particular package.
Can you make calls and texts with an eSIM?
Yes, you can make calls and send texts with an eSIM when the plan includes voice and SMS. With a data-only eSIM, you can call and message through internet apps, but you cannot place a normal carrier call or send a standard SMS from that travel line.
Normal cellular calls
Normal calls use the mobile carrier's voice service and appear in the phone's dialer. A voice-enabled eSIM must have calling service, an assigned number, and coverage where you use it. Check whether the allowance covers local calls, international calls, incoming calls, or only calls within a listed region.
A data-only plan does not gain normal calling just because the phone has a dialer. You would need another active line or an internet calling service.
Internet calls and messages
WhatsApp, FaceTime, Messenger, Signal, Telegram, and similar apps use internet data. They can work through a data-only travel eSIM when the app is available in the destination and the connection is strong enough. The other person usually needs the same app, unless you use a service that can call ordinary phone numbers.
App calls are not the same as carrier calls. They use your data allowance, depend on internet quality, and may not replace access to local emergency or service numbers.
SMS, iMessage, and RCS are different
SMS travels through a carrier line. A data-only eSIM cannot receive a bank code or send a standard SMS because it has no SMS service. iMessage and RCS can use mobile data, but both remain tied to account and phone-number settings. A SIM change may prompt the app to verify the number again.
On an iPhone, check Settings > Apps > Messages > Send & Receive before departure. On Android, check the number and connection status in your messaging app. Do not assume a blue bubble or chat label proves that carrier SMS is available.
Best eSIM for calls and texts: what should you buy?
The best eSIM for calls and texts is a plan that explicitly includes voice, SMS, and a usable phone number for your destination. There is no single provider that fits every route. Compare the exact package, calling area, number country, allowances, validity, and support before paying.
Use this checklist on the package page:
| Check | What the listing should tell you | Why it matters |
|---|---|---|
| Plan type | "Data, voice and SMS" rather than "data only" | Confirms that normal calls and texts are part of the package |
| Phone number | Whether a number is included and its country code | A foreign number may be inconvenient for local contacts |
| Call allowance | Included minutes and eligible destinations | Local, regional, and international calls may have different rules |
| Incoming calls | Whether they use minutes or incur a charge | Receiving a call is not always free |
| SMS allowance | Number of outgoing texts and whether incoming SMS works | Verification messages and short codes may have restrictions |
| Coverage | Every country where voice and data should work | Data coverage does not always prove voice coverage |
| Validity | When the plan starts and when the number expires | A temporary number may stop working at the end of the package |
| Support | A reachable channel before and during the trip | Voice setup can fail even when mobile data connects |
Roaming eSIM publishes this guide and sells travel data plans. The product cards below are shopping links from our live catalog, not an independent ranking of voice providers. Treat a package as data-only unless its product details clearly list calls, SMS, or a phone number.
Do you need a phone number with a travel eSIM?
You need an included phone number if you want people to call the travel line, receive standard SMS on it, or give local businesses a number that works without an app. You do not need a new number for maps, email, web browsing, or app-based calls and messages.
Before choosing a numbered eSIM, check the country code. A plan that works in Europe may assign a number from another country. Calling that number can count as an international call for the person contacting you. Some temporary numbers also cannot receive short-code messages used by banks or ticketing systems.
If a hotel or restaurant accepts WhatsApp, a data-only plan may cover the conversation. If you expect calls from drivers, clinics, government offices, or people who will use the normal dialer, a voice-enabled local plan is easier to explain and test.
Can you keep your home number and receive bank texts?
On a compatible dual-SIM phone, you can keep the home SIM or eSIM active for your usual number while a travel eSIM handles mobile data. Verification texts still go to the home number. Delivery and roaming charges depend on your home carrier, so check its terms before relying on this setup.
Prepare the two lines before departure:
- Sign in to banking, airline, email, and government apps while you are still at home.
- Add an authenticator app, passkey, backup code, or trusted device where the service allows it.
- Ask the home carrier whether incoming SMS works abroad and what calls, voicemail, and messages cost.
- Set the travel eSIM as the mobile-data line.
- Turn off data roaming on the home line unless you knowingly need it.
- Disable automatic data switching if the phone could move data back to the home SIM.
Keeping the home line switched on can expose it to roaming charges even when it is not the data line. A received SMS may be free with one carrier, but calls, voicemail, or outgoing texts can still cost money. Use the carrier's written rates rather than assuming all activity is free.
Will WhatsApp work with a data-only eSIM?
WhatsApp normally keeps the number already registered to your account while the travel eSIM supplies internet access. Messages and calls use data, so the travel eSIM does not need its own phone number. Do not choose "Change Number" unless you intend to move the account.
The same basic idea applies to other app-based services, but account rules differ. FaceTime and iMessage can use your Apple Account email or registered number. RCS may need to verify the active number again. Our travel eSIM vs roaming guide explains how the travel data line and home number can work together.
How do you set up two SIMs for travel calls and data?
Dual-SIM phones can separate the jobs: the travel eSIM supplies data, while the home line or a voice-enabled travel line handles normal calls and SMS. Set the defaults deliberately so the phone does not choose a costly line without warning.
iPhone setup
Apple's Dual SIM guide says supported iPhones can use separate voice and data plans, with one cellular data network active at a time.
- Label the lines, for example "Home" and "Travel."
- Choose the travel eSIM under Cellular Data.
- Choose the line with voice service as the default voice line.
- Turn off Allow Cellular Data Switching if you do not want the home line to carry data.
- Review iMessage, FaceTime, voicemail, and Wi-Fi Calling settings for the home number.
Android and Pixel setup
Google's Pixel Dual SIM guide lets users choose separate defaults for calls, texts, and mobile data on supported phones.
- Open Settings > Network & internet > SIMs.
- Set the travel eSIM as the mobile-data SIM.
- Set calls and texts to the voice-enabled line, or choose "Ask every time."
- Review automatic data switching and data-during-calls settings.
- Test an outgoing call and a text before you depend on either line.
Samsung and other Android menus use different names. The same rule still applies: choose one line for data and confirm which line handles calls and SMS.
eSIM vs physical SIM: which is better for calling?
An eSIM and a physical SIM can provide the same calling quality when they use the same carrier, plan, phone, and network. The SIM format does not make a call clearer or more reliable. Coverage, congestion, supported frequencies, roaming agreements, and the voice package determine the result.
| Calling factor | eSIM | Physical SIM |
|---|---|---|
| Voice quality | Depends on network and plan | Depends on network and plan |
| Normal calls and SMS | Available when included | Available when included |
| Buying before arrival | Often easier | May require delivery or a shop visit |
| Keeping the home SIM installed | Yes | Only if the phone has another slot or the home line is an eSIM |
| Moving service to another phone | Requires a carrier transfer or new profile | The card can often be moved, subject to carrier rules |
| Local phone number | Available from some carrier and travel plans | Common with local prepaid plans |
| Lost-phone response | Profile cannot be physically removed | Card can be removed and placed in another phone |
The GSMA guide to eSIM architecture describes eSIM and removable SIM as different ways to authenticate a device for calls, messages, and network access. For calling, compare the subscription rather than the chip.
A physical local SIM can still be practical for a long stay or a phone without eSIM support. It also suits travelers who need a local prepaid number. An eSIM is easier when you want to buy before arrival and keep the existing SIM in place.
When is a data-only eSIM enough?
A data-only travel eSIM is usually enough when you mainly need maps, transport apps, email, web access, and calls through apps your contacts already use. It also works well when your home line can remain available for occasional verification texts under acceptable roaming terms.
Choose a plan with voice and SMS, a local carrier plan, or controlled home-carrier roaming when:
- You must call ordinary local numbers without relying on an app.
- Hotels, drivers, clients, or family need to call a normal number.
- You need carrier SMS on the travel line.
- Your work or account security depends on a reachable number.
- App-based calling is unreliable or restricted at the destination.

What should you check before checkout?
Read the complete package page instead of relying on the product name or data allowance. Save a screenshot or offline copy of the calling rules because you may need them after arrival.
- Is the package data-only or does it include voice and SMS?
- Does it provide a number, and what is the country code?
- Can you receive calls and texts as well as send them?
- Which destinations can you call without an international charge?
- Do minutes or SMS expire with the data plan?
- Does the number receive bank short codes and verification messages?
- Which network carries voice service at the destination?
- Does your unlocked phone support eSIM and dual SIM?
- What support is available if data works but calling does not?
Our guide to where to buy an eSIM for international travel covers coverage, activation, refunds, and support checks. When setting the data line, follow the package instructions because some travel plans require data roaming on their own line.

Frequently asked questions
Do all eSIMs include a phone number?
No. An eSIM plan includes a phone number only when the carrier or seller assigns one. Many travel eSIMs are data-only and have no number. Check the plan type and number country before buying.
Can a data-only eSIM receive SMS codes?
No. A data-only eSIM has no carrier SMS service. Send verification codes to an active home or voice-enabled travel number, or set up another login method before departure.
Can you call a normal phone number with a data-only eSIM?
Not through the phone's carrier dialer. You need an internet calling service that supports calls to ordinary numbers, or another SIM line with voice service. App-to-app calls work only when both sides use a compatible service.
Will a travel eSIM change your WhatsApp number?
No. Installing a travel eSIM does not automatically change the number registered to WhatsApp. The app can use the new data connection while keeping the existing account number.
Can you leave your physical SIM active with an eSIM?
Yes, on a compatible dual-SIM phone. Use the eSIM for data and the physical SIM for calls or texts if the carrier supports roaming. Check call, SMS, voicemail, and data charges before leaving the home line enabled.
Is eSIM calling less reliable than physical SIM calling?
No. The SIM format does not decide call quality. Reliability depends on the carrier, local network, plan, device support, signal, and congestion. Compare those factors for the exact package and destination.
