Where to Buy an eSIM with Access to Local Networks in Different Countries? A Comparison of the Best Options for Travelers in 2026
Added: 03.08.2026,
Updated: 03.08.2026,
Just a few years ago, most travelers would either search for a local mobile carrier store after landing or rely on expensive roaming services. Today, more and more people choose an eSIM, allowing them to access mobile internet abroad almost immediately after arrival—without replacing their physical SIM card.
The market has grown rapidly, and in 2026 there are now many providers offering travel eSIM plans. However, they differ in the number of supported countries, connection quality, hotspot availability, pricing, and access to local mobile networks.
If you're wondering where to buy an eSIM that provides reliable internet while traveling, this guide compares the most popular providers and helps you choose the best option for your travel style.
Why Choose an eSIM Instead of Roaming?
Until recently, roaming was the easiest way to stay connected while traveling. It still works well for short trips within the European Union, but outside the EU it can quickly become very expensive.
A modern eSIM lets you connect to local mobile networks without purchasing a physical SIM card.
Key benefits include:
- Internet access almost immediately after landing
- No need to visit local carrier stores
- No expensive roaming charges in most destinations
- Keep your existing phone number
- Easy installation using a QR code
- Dual SIM support
- Convenient online top-ups
For most travelers, an eSIM is simply a more convenient—and often more affordable—way to enjoy mobile internet abroad.

Today, travelers typically choose from several types of providers.

Holafly is best known for plans that offer large amounts of data or so-called "unlimited" internet.

Before purchasing, however, you should verify:
- Hotspot availability

- Any speed limitations that may apply
Revolut eSIM

There is no single best provider for everyone. The ideal choice depends on your destination, trip length, and expected data usage.
How Does an eSIM with Local Network Access Work?
When you buy an eSIM, you don't receive a physical SIM card.
Instead:
- You receive a QR code.
- Install the eSIM profile on your device.
- Select the eSIM as your mobile data line.
- Enable data roaming for the eSIM.
- Once you arrive, your phone automatically connects to a supported local operator.
This means you can be online within minutes of landing.
Local eSIM or Regional eSIM?
Local eSIM
A local eSIM is usually the best option if you're visiting only one country.
Examples include:
- Japan
- United States
- Thailand
- Türkiye
These plans typically offer the best price-to-data ratio.
Regional eSIM
Perfect for trips covering multiple countries.
Popular regional plans include:
- Europe
- Asia
- North America
- Middle East
- Balkans
You won't need to switch eSIMs every time you cross a border.
Global eSIM
A global eSIM is ideal for:
- Business travelers
- Digital nomads
- Frequent international travelers
- Multi-continent trips
One eSIM can provide connectivity in more than 100–150 countries.
What Should You Check Before Buying an eSIM?
Not every plan is suitable for every traveler.
Before purchasing, make sure to verify:
- ✔ Whether your phone supports eSIM
- ✔ Whether your device is carrier-unlocked
- ✔ Number of supported countries
- ✔ Access to local network operators
- ✔ Included data allowance
- ✔ Plan validity period
- ✔ Availability of data top-ups
- ✔ Hotspot support
- ✔ Fair Use Policy (FUP)
- ✔ Installation instructions
- ✔ Customer support availability
- ✔ When the plan validity begins
It's also recommended to install your eSIM about two days before departure while connected to stable Wi-Fi. This gives you enough time to resolve any issues before your trip.
Is It Worth Buying an eSIM Through a Marketplace?
There are also marketplaces that compare plans from multiple eSIM providers.
Advantages:
- Easy comparison of different offers
- Wide selection of providers
Potential drawbacks:
- No direct support from the actual provider
- Different refund policies
- Inconsistent plan terms
For many travelers, purchasing directly from an eSIM provider offers a smoother experience and better customer support.
Does a Mobile Wi-Fi Router Still Make Sense?
Absolutely.
Although eSIM has become extremely popular, a portable Wi-Fi router remains an excellent solution for:
- Families
- Groups of friends
- Remote workers using laptops
- Travelers with multiple devices
- Phones that do not support eSIM
A portable hotspot lets several devices share one internet connection, often making it a more economical choice for group travel.
Is an eSIM Worth It?
In most situations, yes.
With an eSIM you can:
- Avoid expensive roaming charges outside the EU
- Get internet access immediately after landing
- Connect to local LTE and 5G networks
- Keep your existing phone number
- Easily manage your data plans
- Travel across multiple countries without changing SIM cards
For frequent travelers, the savings compared with traditional roaming can be significant—especially outside Europe.
How Much Data Do You Need?
Choose your plan based on how you use mobile internet.
3–5 GB
Suitable for:
- Navigation
- Messaging apps
- Booking services
10–20 GB
Recommended for:
- Social media
- Music streaming
- Frequent web browsing
30–50 GB
Ideal for:
- Remote work
- Video meetings

Frequently Asked Questions
Where is the best place to buy an eSIM before traveling?
The safest option is to purchase directly from a trusted eSIM provider. You'll receive the latest plans, installation instructions, and dedicated customer support.
Does an eSIM work immediately after landing?
Yes. If the profile has been installed correctly beforehand and data roaming is enabled for the eSIM, your phone will automatically connect to a supported local network after arrival.
Do I need to replace my physical SIM card?
No. An eSIM is a digital SIM profile installed directly on your device, so there's no need to insert or remove a physical SIM card.
Can I keep my existing phone number?
Yes. In most cases, you can continue using your physical SIM card for calls and SMS while using the eSIM exclusively for mobile data.
Does every phone support eSIM?
No. Before purchasing, check your device specifications or dial *#06#. If your phone displays an EID number or includes an "Add eSIM" option in the settings, it likely supports eSIM. Your phone must also be carrier-unlocked.
Is an eSIM more secure than public Wi-Fi?
Yes. With an eSIM, you connect through a mobile operator's secure cellular network rather than open public Wi-Fi hotspots, reducing the risk of data interception when accessing banking apps, email, or work-related services.
Final Thoughts
In 2026, buying an eSIM with access to local mobile networks is one of the easiest and most convenient ways to stay connected while traveling abroad. Depending on your destination, you can choose a local, regional, or global data plan and enjoy mobile internet without changing physical SIM cards or paying expensive roaming fees.
Several well-known providers—including Airalo, Holafly, Revolut, and Orange Flex—offer travel eSIM solutions.
