The smarter way
to stay connected abroad

An eSIM is a digital SIM card embedded directly into your device. Instead of buying a physical SIM on arrival — queuing at an airport kiosk, figuring out local packaging, hoping it works — you activate a travel plan from your phone before you even board.

The shift to eSIM is one of the most practical upgrades a frequent traveller can make. No more drawer full of foreign SIM cards, no more relying on expensive roaming packages from your home carrier, and no risk of losing your main SIM while swapping it out.

The Basics

What is an eSIM
and how does it work?

A traditional SIM card is a small removable chip that identifies your device on a mobile network. An eSIM (embedded SIM) does the same job — but it's soldered directly into your phone's motherboard. You can't physically swap it, but you can reprogram it wirelessly by downloading a new "SIM profile" from a provider.

In practice: you buy a data plan online, receive a QR code by email, scan it with your phone's camera, and within a few seconds your device has a new local number and data connection for your destination. You can store multiple eSIM profiles at once and switch between them from Settings.

📱
Digital activation
Download your plan via QR code or app. No store visit, no physical card. Activate at home before you travel.
🌍
Multi-country plans
Single regional plans cover Europe, Asia-Pacific, or the Americas — no new SIM for each country crossing.
📡
Dual SIM
Your home number stays active for calls and texts while the eSIM handles data. No need to choose one over the other.

Which phones support eSIM? iPhone XS (2018) and all later models. Samsung Galaxy S20 and later. Google Pixel 3 and later. Most flagship Android devices released since 2021. To confirm: on iPhone, go to Settings → General → About and look for an EID number. On Android, go to Settings → Network → SIM cards. Note that some carrier-locked devices may restrict third-party eSIMs even when the hardware is compatible — check with your home carrier first if unsure.

The Choice

eSIM vs Physical SIM —
which is right for you?

Both work. The choice depends on your trip length, the number of countries you're visiting, and how much data you need. Here's an honest side-by-side.

eSIMPhysical SIM
SetupBefore you fly — QR code scan at homeBuy locally on arrival (airport, convenience store)
Speed of accessInstant — data works as soon as you landRequires finding a store, potentially queuing
CostVaries — competitive on short trips, multi-countryOften cheaper per GB for longer stays in one country
Multi-countrySingle regional plan covers multiple countriesMay need a new SIM per country
Device requirementeSIM-compatible phone onlyWorks on any unlocked phone with a SIM slot
Home numberStays active via dual SIMMay need to remove home SIM to insert travel SIM
ReusabilitySome plans can be topped up; others single-useCan often top up locally; discard when done

When eSIM wins

Short trips (under 3 weeks) where the convenience of instant activation outweighs the slightly higher per-GB cost of travel-specific plans.

Multi-country routes — a single Europe or Asia-Pacific regional eSIM covers multiple countries without re-buying.

Last-minute departures — no time to shop for a local SIM, no language barrier to navigate at a foreign counter.

Travellers who can't swap SIMs — if your phone is carrier-locked to your home SIM, a secondary eSIM for data is the cleanest solution.

When a local SIM wins

Long stays (4+ weeks) in one country — local carriers frequently offer much better data/cost ratios than international travel plans.

High data needs — if you're working remotely and need 30–50 GB a month, a local plan usually offers better value.

Older or budget phones — not eSIM-compatible. A physical SIM is your only option on most mid-range Android devices.

Countries with limited eSIM coverage — some markets in Central Africa and parts of South Asia have patchy eSIM provider support.

Getting Started

How to activate an eSIM
before you fly

The whole process takes under five minutes and should be done on a stable Wi-Fi connection at home — not rushing through airport security.

1
Check your phone is eSIM-compatible and unlocked
Confirm your device supports eSIM (see the "Which phones support eSIM?" section above). Also verify your phone is carrier-unlocked — if you're still under a locked contract, contact your home carrier to unlock it before purchasing a travel eSIM.
2
Choose a plan for your destination(s)
Select a provider and plan based on the countries you're visiting, the number of days, and your estimated data usage. Regional plans (e.g. "Europe 15 days") are usually better value than separate country plans if you're crossing borders.
3
Purchase and receive your QR code
After payment you'll receive a QR code by email (or within the provider's app). Do not scan it yet if your plan has a fixed start date — some plans begin counting down from the moment of installation, not from first use. Read the terms carefully.
4
Install the eSIM profile
On iPhone: go to Settings → Cellular → Add eSIM and scan the QR code. On Android: go to Settings → Network → SIM cards → Add eSIM. You'll need a working internet connection (Wi-Fi or mobile) to complete the download. Do this at home or in your hotel, not at the airport gate.
5
Set data roaming and activate on arrival
Make sure Data Roaming is enabled for the eSIM line in your settings. When you land, your phone should automatically connect to a local partner network. If it doesn't within a few minutes, manually select the eSIM line as your data SIM in Settings.
Coverage

eSIM coverage
around the world

Most major eSIM providers cover 190+ countries, but coverage quality and plan availability vary significantly by region. Here's what to expect.

Europe

Excellent coverage across all EU countries plus the UK, Switzerland, Norway, Iceland and the Balkans. Regional plans work seamlessly across borders. Most providers offer 4G/LTE as standard, with 5G available in major cities on premium plans.

Asia-Pacific

Strong coverage in Japan, South Korea, Thailand, Singapore, Bali, Vietnam and the Philippines. China requires specific plans — standard international eSIMs don't bypass the Great Firewall. Australia and New Zealand are well-covered. Remote Pacific islands are generally not supported.

Americas

Comprehensive coverage across the USA, Canada and Mexico. Most Central American countries are well-supported. South America coverage is strong in Brazil, Argentina, Chile, Colombia and Peru; more limited in remote Amazonian and Andean regions. The Caribbean varies significantly by island.

Middle East & Africa

UAE, Saudi Arabia, Qatar, Turkey and Israel are well-covered. Most North African countries (Morocco, Egypt, Tunisia) are supported. Sub-Saharan Africa coverage is concentrated in South Africa, Kenya, Nigeria and Ghana. Remote or conflict-affected regions typically have no eSIM support.

Head to Head

Airalo vs Yesim —
which one to buy

Two providers dominate the travel eSIM market, and they are built for different travellers. Airalo has the larger catalogue and the better-known brand; Yesim is cheaper per gigabyte on most regional plans and lets you keep one profile across several countries. Below is the honest split.

Our pick

Yesim

Best value per gigabyte

  • ✓ Cheaper regional bundles on most of Europe and Asia
  • ✓ One profile usable across multiple countries on a single trip
  • ✓ Pay-as-you-go option if you only need light data
  • ✓ Top-ups handled in-app, no second QR code
  • · Smaller catalogue of single-country plans
See Yesim plans →

Airalo

Widest country coverage

  • ✓ Plans in 200+ destinations, including hard-to-cover markets
  • ✓ The most established brand — largest body of user reviews
  • ✓ Strong single-country plans for long stays
  • ✓ Loyalty credit if you travel often
  • · Usually costs more per gigabyte on regional bundles
See Airalo plans →

The short answer. One country, one trip, somewhere unusual — Airalo. Several countries in one journey, or a Europe/Asia region hop where price per gigabyte decides — Yesim. Both activate the same way and both keep your home number live on the second line, so the choice is about plan shape and price, not about how they work.

Which eSIM for your trip?

The better eSIM depends less on the brand than on the shape of your journey. Here is what we would pick for the most common trips.

Our pick: Yesim

Europe, several countries

A single profile that follows you across borders is exactly what a rail trip or a city-hop through Europe needs. Airalo’s Europe regional package is the alternative if you prefer a fixed bundle.

See Yesim Europe plans →
Our pick: Either

Croatia, Greece or one Mediterranean country

For one country, both work well: pick Airalo’s local plan for a long stay, or Yesim if you might cross into a neighbouring country — Croatia to Slovenia or Montenegro, for example.

Compare Yesim plans →
Our pick: Airalo

USA or Canada

Strong single-country plans for North America and the largest catalogue of data sizes, useful for long road trips.

See Airalo USA plans →
Our pick: Either

Japan, Korea or Southeast Asia

Both cover the region well. Choose a regional Asia plan if you are combining countries; otherwise compare the single-country price in each app.

Our pick: Yesim

Light data, short trip

Pay-as-you-go means you only pay for the megabytes you actually use — ideal for maps and messaging on a long weekend.

FAQ

eSIM Travel Questions Answered

It depends on the shape of your trip. Choose Airalo if you are visiting a single country, staying a while, or heading somewhere less commonly covered — it has the largest catalogue, with plans in over 200 destinations. Choose Yesim if you are crossing several countries on one journey: a single profile follows you across borders. Which one is cheaper depends on the destination and how much data you use, so compare the price for your exact trip in each app. Both activate identically by QR code, and both let your home number stay active on the second SIM line. See the full comparison →
Most smartphones released since 2020 support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. To confirm on iPhone: go to Settings → General → About and look for an EID number. On Android: Settings → Network → SIM cards. Note that some carrier-locked devices may restrict third-party eSIMs even if the hardware is compatible.
Yes. Most eSIM-compatible devices support dual SIM: your home physical SIM (or eSIM) handles calls and texts, while the travel eSIM provides local data. You can receive calls on your regular number even when actively routing data through the travel eSIM. Check your device's Dual SIM settings before you leave.
It depends on the provider. Some eSIM profiles can be topped up or reactivated for future trips; others are single-use and must be deleted once expired. Check your specific provider's terms before purchasing if reusability is important to you.
Most providers will either stop your data or throttle it to a slow speed. You can usually top up directly through the provider's app without a new QR code. It's worth buying slightly more data than you expect to use rather than running out in a remote area with no Wi-Fi access.
In most cases, yes — significantly so. A travel eSIM usually costs far less than your mobile carrier's daily roaming pass for the same amount of data. The difference is most noticeable on trips over five days or when visiting multiple countries on a single journey.
It depends on the trip. Prices change often and vary by destination and data size, so compare the plan for your exact trip in each app. As a rule of thumb, Yesim pay-as-you-go is often the better deal for light use, while a fixed Airalo package can be good value for a longer stay in one country.
If you are crossing several countries, choose a single Yesim profile or Airalo’s Europe regional package so you do not need a new plan at each border. If you are staying in one country, compare the local single-country plan from each provider.
Yes. These travel eSIMs are data-only: your home line stays active on the other SIM slot for calls and texts, and WhatsApp keeps working with your usual number over the eSIM data.
