What is an eSIM?

An eSIM is a digital SIM built into your phone. You download a mobile plan with a QR code or an app, and the phone stores it electronically. You do not need to remove a physical card or buy one at the airport.

For travelers, this has two practical benefits. You can buy and activate data before you leave, and you can keep your home number on your primary SIM while you use a travel data plan on a second line.

How to choose an eSIM for travel

Five checks cover most of the decision. Run through them for each provider before you pay.

1. Coverage

Confirm that the plan covers every country on your route. A regional plan can cover many European countries, while a single-country plan suits a one-stop trip. Read the coverage list on the product page, not the provider's homepage.

2. Data and validity

Compare the gigabytes and the number of days. Estimate your daily use before you choose. Maps, messaging, and photo uploads use more data than most travelers expect.

3. Phone compatibility

Your phone must support eSIM and must be unlocked. Check the provider's compatibility list for your phone model before you buy.

4. Activation timing

Most plans start counting validity when you first connect to a network, not when you buy. Confirm this on the product page, so you do not waste days by activating too early.

5. Support and refunds

Read the refund policy before you pay. Find out how to reach support in English, and what they can and cannot fix remotely.

The 4 best eSIMs for travel

Each entry below covers who the provider suits and what to check on its site. We have not included prices, data sizes, or country counts here, because those change often. Confirm them on the provider's page before you buy.

1. Airalo

Best for: travelers who want regional plans that cover many countries in one purchase.

Airalo is one of the best-known eSIM marketplaces. It lists regional and single-country plans, with data and validity shown on each product page. For a multi-country route, check that the regional plan includes every country you will visit.

Promo codes: new Airalo users can enter GETDOCUTRIP at checkout for 15% off. Returning users can use MENTARICH for 10% off. Both are subject to Airalo's offer terms shown at checkout.

Two points matter most before you buy. First, unlimited-style plans have a fair-use limit: Airalo's terms reduce speed to about 1 Mbps after 3 GB in a day on some unlimited plans, so heavy users should choose a fixed data plan instead. Second, eSIMs bought on Airalo generally cannot be reinstalled once used, so keep the QR code and install it on the device you will travel with.

• Check the fair-use terms on the plan page, not only the headline data amount.
• Confirm the plan works on your phone model before you buy.

2. Yesim

Best for: travelers who want to compare plans for a specific destination.

Yesim offers eSIM plans for travel. Compare data, validity, and coverage on the product page for your destination, and confirm the plan works with your phone before you buy.

Yesim is useful if you want a pay-as-you-go balance. Its balance does not expire, so a small top-up can wait for a later trip. Hotspot is included on most plans, which matters if you share a laptop or tablet. Two limits to note: refunds are narrow, and activation can be delayed for up to 180 days after purchase, so buy close to your departure date.

• Read the refund conditions before you pay, because they are narrower than most providers.
• Check whether the plan you choose has a published speed limit after heavy use.

3. Saily

Best for: travelers who want a simple app-based setup.

Saily manages its eSIM plans through an app and a website. Confirm coverage for your route and check how the app handles activation and plan changes.

Saily gives the clearest refund window of the four: a full refund is available within 30 days if you have not installed or activated the plan. Setup is fast, and the eSIM can be moved to another device. The trade-offs are that plans are data-only by default, unlimited plans slow to about 1 Mbps after heavy use, and live chat is available only inside the app.

• Install the app before your trip and log in at home, since support is easier to reach there.
• Keep the refund window in mind: it closes once the plan is activated.

4. Drimsim

Best for: travelers who want a budget-focused option for specific destinations.

Drimsim offers eSIM plans for travel. Compare its coverage and validity against your itinerary. Budget plans often cover fewer countries, so check the list before you buy.

Drimsim is a pay-as-you-go, data-only option with no monthly fee. Its refund applies if the connection fails within 24 hours, and the QR code is delivered by email. Cost per gigabyte is higher on some destination pages (about €10/GB on the Vietnam page at the time of our check), so compare the per-GB price against other providers for the same country. Confirm that your phone model is on its supported list, which covers recent iPhone and Android models.

• Use it when you need a short, single-destination plan and the per-GB cost is acceptable.
• Check the device list before you buy, because older models may not be supported.

How much data do you need?

Start with a simple estimate. Light use, such as messaging, maps, and checking email, uses far less data than video calls, streaming, or uploading photos. Most travelers find that maps and social media make up the bulk of their daily use.

A rough daily estimate

• Light use: messaging and maps, with occasional browsing.
• Medium use: the same, plus some photo uploads and short video calls.
• Heavy use: streaming, frequent video calls, or working remotely from abroad.

Pick a plan with a margin above your estimate. Running out of data in the middle of a trip costs more time than paying for a slightly larger plan.

Pick a plan by traveler type

Short trips with one destination

A single-country plan is usually the simplest choice. Check the validity period and confirm that the plan starts when you connect, not when you buy.

Multi-country routes

A regional plan is more practical if you cross borders often. Read the coverage list and confirm every country on your itinerary is included, including any stop you may add later.

Business travelers

If you depend on your phone for work, check the speed and the fair-use terms before you buy. Some plans reduce speed after a data threshold, and the product page may not highlight this.

Budget travelers

Compare the cost per gigabyte across providers, but also check the coverage list. A cheaper plan that misses one country on your route can cost you more in the end.

Use this table as a checklist. Fill it in for each provider before you pay.

How to set up your eSIM before you leave

1. List your countries and dates. Write down every country on your route and the number of days.
2. Choose a plan that covers all of them. A single-country plan can be cheaper if you visit only one country.
3. Buy and install at home. Scan the QR code or install through the app while you have Wi-Fi.
4. Keep the plan off until you land. Turn it on when you arrive, and set data roaming on for that line.
5. Save the provider's support contact. You may need it if activation fails abroad.

Common mistakes

• Buying a plan that does not include every country on your route.
• Forgetting that the phone must be unlocked.
• Activating the plan at home, which can start the validity period early.
• Assuming the plan includes calls or SMS. Most eSIM plans are data-only.
• Waiting until you land to install the eSIM, when the airport Wi-Fi may be slow or unavailable.

Where an eSIM fits in your trip planning

An eSIM solves the connectivity part of travel. It does not replace your visa. Check your visa requirements well before you travel.

• Use our visa approval predictor for an AI-based estimate of your approval chances. It is an estimate, not a guarantee.
• Read the Schengen visa guide for the application steps.
• Check your paperwork with the visa document checklist.
• Use the things to do before your trip checklist to organize documents and bookings.

Frequently asked questions

Do I need a physical SIM card for an eSIM?

No, if your phone supports eSIM and is unlocked. The eSIM replaces the physical card.

Can I keep my home number while using an eSIM?

Often yes. Many phones support two lines, so you can keep your home number active and use the eSIM for data. Check your phone's dual SIM settings and your carrier's roaming options.

When should I buy an eSIM?

Buy it before you leave, then install it at home. Activate it when you arrive.

Is GetDocuTrip a visa agency?

No. GetDocuTrip is not an official visa agency and does not guarantee visa approval. Check requirements with the embassy or consulate of the country you are visiting.
