An eSIM with a phone number is a digital SIM profile that includes a number of its own, so you can make calls, send and receive texts and use data without a physical card. Not every eSIM sold to travelers works this way. Most are data-only, and many that advertise a “number” are internet-based lines that only receive texts. Before you buy, decide what you need the number for, then match the plan to that job.
This guide explains the difference between real and virtual numbers, shows when you can skip a number entirely, and walks through setup on a phone that already holds your home line.
A standard travel eSIM is a data plan. It gives your phone a mobile internet connection in the country you land in, and nothing else. There is no number attached, so you cannot be dialed on it and you cannot text from it in the usual way.
An eSIM with a phone number adds a voice and SMS line to that profile. It behaves like a prepaid SIM: you get a number, you can place and receive calls, and you can exchange texts. The only difference is that you install it by scanning a QR code or tapping a link rather than inserting a card. If the basics are new to you, our explainer on what an eSIM is and how it works covers the technology in plain terms.
You will see three kinds of product sold under the same label:
| Type | What it gives you | Typical weakness |
|---|---|---|
| Data-only eSIM | Mobile internet in the destination | No number, no native calls or texts |
| eSIM with a native cellular number | Calls, SMS and data on a local or regional network | Costs more, often limited to certain regions or validity periods |
| eSIM with a virtual (VoIP) number | A number that works over the internet | Calls may not connect like a normal line, and texting can be limited to inbound messages |
The third category is where buyers get caught. A review of eSIMs with phone numbers points out that many plans marketed with a number are cloud numbers that do not support native cellular calls, or that only receive one-time passcodes. It advises checking for outbound calling before you pay, because providers often blur these features in their marketing. We agree with that advice. Read the plan description for the words “outgoing calls” and “SMS send and receive,” not just “phone number.”
Often you do not. If your goal is to stay in touch with family, check in with the office or use maps and rideshare apps, a data-only eSIM plus the apps you already use covers it. Calls and messages over WhatsApp, FaceTime or similar apps still link to your existing home number, and the same review notes that data-only eSIMs are significantly cheaper and more widely available than plans with a native number.
There is a second reason to keep your home SIM active. Your bank, airline and email accounts may send verification codes by text to your usual number. If you swap that number out, those codes stop arriving. Keeping your home line on and adding a travel eSIM for data avoids the problem. We cover the cost side of this in eSIM vs roaming, which shows how to keep your home line without paying roaming rates for data.
A number-bearing eSIM needs a phone that supports eSIM and is not locked to a carrier that blocks other profiles. Apple’s support pages state that eSIM works on iPhone XS and newer, and that an iPhone can store multiple eSIMs, so you can keep your home number alongside a travel plan. On the Google side, Pixel help notes that Pixel 10, Pixel 10 Pro and Pixel 10 Pro XL sold in the US have no physical SIM at all and are eSIM-only. If you own one of those, an eSIM is not a nice extra. It is the only way to add a second line.
Two checks save headaches:
Dual-line setups are what make travel eSIMs practical. Your phone keeps your home line and adds the travel profile. Here is the usual routine:
This arrangement gives you the best of both worlds: your regular number for incoming calls and codes, a local data connection, and, if you buy one, a second number for local use.
The label “with phone number” hides many differences. Run any plan through this list.
We sell prepaid eSIM plans for travelers with one-time payments, and we are straightforward about what each does. The table below lists current prices as published on our site.
| Plan | Data | Price | Best for |
|---|---|---|---|
| Global Travel eSIM | 1 GB | £7.99 | A short stopover |
| Global Travel eSIM | 3 GB | £15.49 | A long weekend |
| Global Travel eSIM | 5 GB | from £18.99 | A week of light use |
| Global Travel eSIM | 10 GB | from £33.49 | Two weeks with maps and video calls |
| Global Travel eSIM | 20 GB | £59.99 | Heavy use or remote work |
| North America Travel eSIM | 1 GB | £25.52 | Brief trips to North America |
| Premium Europe eSIM (calls, SMS and data) | 2 GB | £9.11 | Europe trips where you want a number |
| Data Only US | 10 GB | £10.99 | US trips with data needs |
The Global Travel eSIM plans are data plans. They keep you online in more than 190 destinations while your home number handles the rest through your usual apps. That is the right pick for most travelers.
If you are heading to Europe and want a real line, the Premium Europe eSIM combines calls, SMS and data, and includes a dedicated number. Our page on Premium Europe eSIM data, calls and SMS explains how it works, and you can see the plan on our plans page. Heading to Spain? Our Spain eSIM guide covers coverage in Barcelona, Madrid and beyond.
For the United States we offer data, not a US number. If a US number is essential for you, for example for a local phone verification, ask yourself whether a data plan with your home line kept active would meet the need first. If you only need data, our Data Only US plan is designed for that.
The most common mix-up we see is between wanting a number and wanting to be reachable. They sound the same, but they are not. Most people who say they want a number actually want family, colleagues or an airline to be able to reach them, and that is solved by keeping the home line on and adding data.
Where a real number earns its place is Europe, where a traveler may cross several borders in a week and deal with hotels, drivers and clinics that prefer a phone call. That is why we built a Premium Europe plan with calls, SMS and data, rather than pushing a number on every itinerary.
The second thing we tell people is to install early. A reusable eSIM, one you install once and top up for later trips, takes the pressure out of the airport arrivals hall. You can read how that works in our guide to reusable eSIMs and top-ups, or head to the top-ups page if you already have one installed.
Third, if setup does not go to plan, talk to a person. Our support team answers on WhatsApp, which is useful when you are standing in a foreign airport with half a signal.

Some trips need more thought than a holiday.
Pilgrimage. If you are traveling for Umrah or Hajj, you may need to reach group leaders, family at home and local services, often while moving between crowded sites. Our Umrah and Hajj eSIM guide covers staying connected in Saudi Arabia.
Medical travel. A clinic may want to text or call you with appointment times. Our Turkey medical travel connectivity guide explains how to plan for that.
Families. Give each traveler their own profile if they each have a phone, or set up one phone as a hotspot for a tablet. Make sure children’s phones are eSIM-compatible before departure. For a family, a shared data plan is easier to track than several numbers.
Whatever the trip, check the rules of your insurer too. Our piece on travel insurance and eSIMs lists what to sort out before you fly, such as having an emergency contact line that works abroad.
Use this quick decision path:
If you want data in more than 190 destinations with a number you already own, start with our Global Travel eSIM plans. If your trip is in Europe and you want calls and SMS, look at the Premium Europe eSIM on the plans page. You can also browse eSIM countries to check your destination before you buy. Orders arrive by email, and our WhatsApp support is there if you need a hand with installation.
Yes, on a phone that supports eSIM and dual lines. Your home SIM or eSIM stays active for calls and texts, and the travel eSIM is set as the data line. Turn off data roaming on the home line to avoid extra charges.
Usually yes. Plans with a native number carry voice and SMS on top of data, and data-only eSIMs are significantly cheaper and more widely available, according to one review. Compare the price against what you would actually use the number for.
Sometimes. Virtual numbers can be limited to inbound texts, and some services refuse certain number types. If codes are the main goal, keep your home line active or confirm before you buy that the plan supports the messages you expect.
Yes. Some phones, such as the Pixel 10 models sold in the US, use eSIM only. You install your plans digitally, and the phone can store more than one profile.
Our US option, Data Only US, is a data plan, so it does not include a number. For calls and SMS, we offer the Premium Europe eSIM for trips in Europe.
