Looking for the most convenient SIM for you?
Let's customize the best packages for you!
In today’s digital era, staying connected while traveling internationally has become more essential than ever. More and more travelers are switching to eSIMs instead of traditional physical SIM cards to enjoy greater convenience and flexibility. But What is an eSIM, and why has it become the preferred choice for so many people?
What is an eSIM?
An eSIM, or "embedded SIM," is a small chip that is permanently built into your smartphone or other connected devices. Unlike traditional SIM cards that require manual insertion, an eSIM is integrated into your device’s hardware and can be programmed remotely.
No physical card needed: eSIM eliminates the hassle of inserting or swapping plastic SIM cards.
Remote activation: Mobile plans can be downloaded directly to your device over the internet.
Multiple profiles: You can store more than one carrier profile on your eSIM and switch between them as needed.
eSIM technology is now supported by a wide range of devices, including:
Smartphones: iPhone (XS and later), Samsung Galaxy (S20 and later), Google Pixel (Pixel 3 and later)
Tablets: iPad Pro, iPad Air (3rd Gen and later)
Smartwatches: Apple Watch, Samsung Galaxy Watch
Laptops: Some models from Lenovo, Microsoft Surface, and HP
With its convenience and flexibility, eSIM is increasingly popular among travelers and digital nomads who frequently switch between mobile carriers or need affordable international data plans.
An eSIM works by allowing your device to store carrier profiles that can be downloaded and rewritten multiple times when necessary.
Step 1: Purchase an eSIM Plan
Choose a reliable carrier or eSIM provider that offers international or local data plans compatible with your destination.
Make sure your device supports eSIM technology.
Complete your purchase online or via your carrier's app.
Step 2: Receive Your eSIM Activation Details
After purchase, you will receive either: A QR code (most common and convenient option). A manual activation code (SM-DP+ address and activation code).
This will be sent via email or displayed on your provider’s website/app.
Step 3: Add eSIM to Your Device
Open your device’s Settings.
Navigate to Mobile/Cellular Network > Add eSIM or Add Cellular Plan (depending on your device).
Option A: Use your device’s camera to scan the QR code provided.
Option B: If scanning isn’t possible, manually input the activation code and other required details.
Step 4: Confirm and Activate
Follow the on-screen prompts to confirm the installation of the carrier profile.
Your device may ask you to label the eSIM (e.g., "Travel Plan" or "Work").

Step 5: Ready to Use
Once installed and activated, you can: Instantly connect to the local network.
Start using mobile data, make calls, and send texts according to the plan you purchased.
Switching networks: Easily toggle between different carriers without needing to replace any SIM cards.
Adding new profiles: Download new carrier profiles directly to your device when needed.
Deleting profiles: Remove old or unused profiles via your device settings.
As the world becomes more connected, travelers face a common question: Should I stick with a traditional SIM card or switch to a travel eSIM? While both options have their merits, eSIMs are fast becoming the preferred choice for savvy globetrotters

The shift from physical SIM cards to eSIMs among the travel community is far from coincidental. Here are the key reasons why eSIM for travel have become the best go-to solution.
1. Instant connectivity upon arrival
Imagine landing at a busy airport after a long-haul flight—you’re tired and eager to get online to check maps, book a ride, or update family and friends. With eSIM technology, you can activate your data plan before boarding your flight, ensuring instant internet access the moment you touch down. No more wasting time searching for SIM card kiosks or struggling with language barriers to purchase a local SIM.
2. Significant savings on roaming costs
One of the biggest pain points for international travelers is hefty roaming charges from home carriers. eSIMs solve this by letting you:
Choose affordable local or regional data plans.
Avoid unnecessary roaming fees.
Enjoy transparent pricing with prepaid options, so you know exactly what you’re spending.
For example, instead of paying $10/day in roaming fees, an eSIM travel plan might cost you as little as $5 for a full week of data in some countries.
3. Effortless purchase and switching of plans
With eSIM travel, you can buy and switch between plans anytime, anywhere. Whether you’re sitting at home before your trip or hopping between countries on a multi-stop journey, eSIMs allow:
Instant downloads of new plans via QR codes or apps.
Switching carriers directly from your phone settings.
Flexibility to pick the best deal depending on your next destination.
This is perfect for travelers who cross borders frequently and need flexible data options.
4. Enhanced Security—No More Lost SIM Cards
Since eSIMs are embedded directly into your device:
You eliminate the chance of misplacing tiny SIM cards.
You avoid the frustration of carrying SIM ejector tools or adapters.
It’s a safer, more reliable option for those always on the move.
Common scenarios where eSIM is a game-changer
Beyond general advantages, eSIMs prove to be exceptionally useful in specific situations, including:
1. Business travelers on short or long-term trips
For professionals who regularly travel for meetings, conferences, or long-term assignments abroad:
eSIMs allow them to stay connected seamlessly, without interruptions.
They can switch between business and personal data plans as needed.
2. Backpackers & adventure travelers crossing multiple countries
Traveling across borders frequently on a single trip? eSIMs enable you to:
Activate local data plans specific to each country.
Avoid the hassle of buying multiple physical SIMs.
Save money and stay connected even in remote areas.
3. Digital nomads & remote workers
For remote workers who live a borderless lifestyle, eSIMs:
Offer the freedom to switch between networks depending on where you are working from.
Ensure stable connections for video calls, uploads, and remote work tools.
Support multiple profiles, so you can balance both work and personal data needs easily.
