Introduction to eSIM
If you’re traveling abroad, you no longer need to swap SIM cards, stand in line for a local carrier, or pay for expensive postpaid plans. With an eSIM, staying connected is easier, faster, and smarter.
An eSIM, or embedded SIM card, is built directly into your phone. You can activate it using a QR code or through your provider’s app, skipping the need for a physical SIM or SIM tray. This makes it the perfect solution for international travelers who want flexibility and control.
Most phones released after 2018, including the iPhone XR, iPhone XS, Samsung Galaxy S20+, and Google Pixel 3+, support eSIM download. Before you start your international travel, open your phone settings to confirm eSIM compatibility and prepare for a seamless setup process.
What is an eSIM and How It Works
An eSIM is a digital replacement for a traditional SIM card that allows you to manage multiple phone plans without swapping cards. Unlike traditional SIM cards, an eSIM is embedded directly in your device.
This enhances web protection and prevents theft or damage. It’s secure, eco-friendly, and reliable. Additionally, eSIMs are more secure than physical SIMs because they cannot be removed if the phone is lost or stolen.
With an eSIM, you can have one line for work and another for travel, making it perfect for frequent flyers and business travelers. It’s easy to manage data plans, control data usage, and switch carriers in seconds. eSIMs can support personal hotspot usage, which is essential for travelers who rely on internet access for work.
The technology also improves battery efficiency and ensures stronger connectivity on most networks. From prepaid plans to unlimited data options, an eSIM works for every traveler.
Benefits of Using eSIM for Travel
When traveling abroad, an eSIM gives you full control over your connection. Here’s why international travelers love it:
Easy activation: Use your phone’s camera to scan a QR code and activate instantly.
Affordable prices: Skip postpaid plans and choose flexible regional or global eSIM packages.
Save money: Avoid roaming costs from big networks like T-Mobile and Verizon.
Unlimited plans: Get high speed data without worrying about data limits.
Personal hotspot support: Share your internet connection safely with other devices.

eSIMs are perfect for short-term vacations, digital nomads, or business trips. Whether you’re using iPhone XR or newer, Samsung, or Google Pixel, eSIM download is quick and reliable.
Why eSIMs Are Better Than Physical SIM Cards
Traditional sim cards are inconvenient and outdated. They require a local provider, a SIM tray tool, and often a passport to activate. eSIMs eliminate all of this.
You can add eSIM options to your phone with just a few taps. For travelers visiting multiple countries, this is a game changer. An eSIM also provides stronger protection than a physical SIM, reducing the risk of cloning or loss. Plus, with most phones now supporting eSIM, users experience faster setup, better data usage control, and simpler network switching.
And the best part? eSIMs are significantly cheaper and help travelers save money while enjoying reliable international roaming coverage.
How to Set Up Your eSIM Before Traveling
Setting up an eSIM before your trip is simple. Follow these steps: To activate an eSIM, you typically need to follow the steps provided by the eSIM provider after purchase.
Check compatibility: Make sure your phone model supports eSIM and that it’s unlocked.
Choose your provider: Compare eSIM brands like Firsty, Airalo eSIM, or Nomad to find the best data plans for your route.
Purchase your plan: Select from prepaid plans, or global eSIM options.
Scan your QR code: Scan to QR code with your phone's camera.
Restart your phone: Some phones complete the setup process after a quick restart. Updating phone settings is often required after eSIM installation to enable data usage.
Once your plan is activated, your eSIM works instantly. You can manage your phone plan, view data usage, and use your personal hotspot directly from your device.
Choosing the Right eSIM Provider
Choosing the right eSIM provider depends on your needs, travel plans, and data usage. Here’s what to look for: Many eSIM providers, such as Firsty, Airalo, Nomad, and Holafly, offer regional plans that cover multiple countries. Several eSIM providers partner with local network operators to ensure reliable connections in popular areas.

Plan flexibility: Look for unlimited data plans, global eSIM options, and regional plans that fit your destinations.
Affordable prices: Compare cost per GB and check for better deals or additional benefits.
App usability: Some providers require you to install other apps for management and setup. Firsty offers enhanced security features and is user-friendly, with an app that provides clear instructions.

Using eSIM with a Local Carrier
You can combine your primary line with an eSIM for mobile data while keeping your main phone number active. This way, you can still receive calls and texts while using a travel eSIM for internet.
When using eSIM with a local carrier, always verify:
Compatibility with your phone model.
Data usage policies and speed limits.
Regional coverage and roaming restrictions.
Access to local data rates via eSIM is often cheaper than international roaming charges from your home carrier. Data roaming must be enabled for the travel eSIM to work while abroad.
Data Plans and Pricing
eSIMs offer flexible pricing for all types of travelers. Many eSIMs do not include a phone number, focusing primarily on data services.
Prepaid plans: Fixed data packages for a specific duration.
Unlimited plans: Great for streaming, social media, and navigation.
Global plans: Work across multiple regions, ideal for long trips.
Regional plans: Focused on one continent, like Europe or Asia.
Pay-as-you-go options: Best for light users who want affordable flexibility.
Compare prices and data limits carefully. Look for high-speed data, no hidden additional fees, and options to top up easily.
Providers like Airalo eSIM and Nomad offer competitive prices, but Firsty takes it further with completely free and flexible solutions. Firsty collaborates with local telco companies to provide affordability and reliability in over 170 countries.
