Quick answer
Yes, you can make normal phone calls on an eSIM, as long as your plan includes voice. An eSIM is simply a digital SIM, so it handles calls and texts just like a physical one when the plan supports them. The catch is that most travel eSIMs are sold data-only, so you need a voice-enabled eSIM, such as WorldSIM eSIM Pro, which comes with a real UK and USA number for calls and SMS.
There is a widespread belief that an eSIM can only do data. It is one of the most common reasons travellers wrongly assume they must rely on WhatsApp for everything. The truth is simpler: an eSIM can absolutely make and receive ordinary calls; whether yours does depends entirely on the plan you buy.
Can you make normal phone calls on an eSIM?
Yes. An eSIM is just a SIM in digital form, embedded in your phone instead of slotted in as a card. Technically it carries voice calls and SMS exactly like a physical SIM. So when people say “you can’t call on an eSIM,” what is actually true is that their specific eSIM plan is data-only. Choose a plan that includes voice, and you can dial any number and receive calls normally.
Why are most travel eSIMs data-only?
Most travel eSIM brands sell data-only plans because data is easier to provision across dozens of countries and because they assume travelers will use apps for calls. That is a product decision, not a technical barrier. It does leave a real gap, though, because plenty of everyday situations need a proper phone call. Providers that include voice and a genuine number, like WorldSIM, are simply less common, which is covered in our eSIM myths article.
Compare WorldSIM eSIM Pro with mobile networks
Although many travel eSIM providers focus only on mobile data, travellers often need much more than an internet connection. Whether you’re calling a hotel, contacting a taxi driver, receiving SMS verification codes, or speaking with local businesses, having a voice-enabled eSIM makes travelling much easier. Unlike many travel eSIMs and expensive roaming services, WorldSIM eSIM Pro combines data, voice calls, SMS, and international coverage in one solution.

| WorldSIM eSIM Pro | £25 | £0.04/min incoming, £0.34/min outgoing | £0.15 per message | 10GB–85GB bundles (£5–30/GB) | All 195+ countries |

App calls vs real phone calls: the difference that matters
WhatsApp and FaceTime are great, but they only work when the other person uses the same app and has the internet. A real phone call works with any number.
| Feature | App calls (WhatsApp, etc.) | Real calls (voice eSIM) |
|---|---|---|
| Can call any phone number | No, app users only | Yes, any number |
| Call hotels, taxis, businesses | Rarely | Yes |
| Receive SMS verification codes | No | Yes |
| Needs internet to work | Yes | No, uses the network |
| Has its own phone number | Tied to your existing number | Yes, a real UK/USA number |
When you really need real calls abroad
The moments a data-only plan cannot handle are more frequent than people expect: phoning a restaurant to confirm a booking, calling a taxi or transfer driver, reaching a car-hire desk, speaking to a hotel that does not use apps, or receiving a one-time SMS passcode from your bank. For any of these, a voice-enabled eSIM is the difference between a quick call and being stuck.
How to get an eSIM with calls and a real number
It is the same simple process as any eSIM, just with a voice-enabled plan.
- Choose a voice eSIM such as WorldSIM eSIM Pro, which includes calls, SMS and a real UK (+44) and USA (+1) number.
- Receive the eSIM QR code by email and install it on home Wi-Fi before you travel.
- Keep your home SIM in the phone if you want to retain your usual number too, via dual SIM.
- Switch the eSIM on when you land; make and receive calls and texts normally, no app required.
If your trip is to a specific country, you can also look at a dedicated line such as a USA number or UK number, or add a standalone virtual number.
Get an eSIM you can actually call from WorldSIM eSIM Pro includes voice calls, SMS and your own UK and USA number across 100+ countries, with no roaming charges. Real calls, not just apps. See eSIM Pro plans

Frequently asked questions
Q: Can you make normal phone calls on an eSIM?
A: Yes, if your plan includes voice. An eSIM is a digital SIM, so it carries calls and texts like a physical SIM when the plan supports them. The catch is that most travel eSIMs are data-only, so choose a voice-enabled eSIM, such as WorldSIM eSIM Pro, to make and receive ordinary calls.
Q: Why are most travel eSIMs data-only?
A: Most providers sell data-only plans because data is simpler to provision across many countries and they assume travellers use apps for calls. It is a product choice, not a technical limit. Providers that also offer voice and a real number, like WorldSIM, are less common.
Q: What is the difference between app calls and real eSIM calls?
A: App calls like WhatsApp only work when both people use the same app and have the internet. Real calls on a voice eSIM use the mobile network and can dial any number, including hotels, taxis and landlines, and receive calls and SMS without the other person needing an app.
Q: Can I get a phone number with my eSIM?
A: Yes, with a voice-enabled eSIM. WorldSIM eSIM Pro comes with a real UK (+44) and USA (+1) number, so you can be called and texted on a normal number, receive SMS codes, and make outgoing calls without apps. Data-only eSIMs typically do not provide a usable number for calls.
Q: Do I need Wi-Fi to make calls on an eSIM?
A: No. Calls on a voice eSIM use the mobile network, so they work anywhere you have signal, no Wi-Fi needed. Only app-based calls like WhatsApp require the internet. This is a key advantage when you need to phone a business that does not use messaging apps.
Q: Can a WorldSIM eSIM Pro receive OTPs from banks and government sites?
Yes. WorldSIM’s eSIM Pro is SMS-enabled and receives one-time passwords from UK banks (Barclays, Monzo, HSBC), HMRC, PayPal, Apple, and Google in 195+ countries, just like a physical SIM.
