What Exactly is an eSIM?
Before we jump into the setup process, let us make sure you understand what you are working with.
eSIM stands for embedded SIM. Unlike the physical SIM card you are probably used to, an eSIM is built directly into your phone. You cannot see it, touch it, or remove it. Instead of inserting a plastic card, you download your mobile plan digitally.
Think of it like this: a physical SIM is like a key you insert into a lock. An eSIM is like having the key stored in your phone’s memory, ready to unlock the network whenever you need it.
Why does this matter to you?
The main advantage is convenience. You can switch carriers without waiting for a new SIM card to arrive in the mail. You can add a second phone number for work or travel without carrying two phones. You can even store multiple plans and switch between them instantly.
For travelers, eSIM is a game changer. Instead of hunting for a local SIM card when you land in a new country, you can buy a data plan online and have it working within minutes.
Before You Start – What You Will Need
Setting up an eSIM requires a few things. Make sure you have everything ready before you begin.
A compatible carrier:
Not every mobile carrier supports eSIM. In 2026, most major carriers do, but it is worth checking before you start.
A stable internet connection:
You need Wi-Fi or mobile data to download the eSIM profile. This is essential for the setup.
Your eSIM activation details:
Depending on your carrier, you will need either a QR code, an activation code, or a carrier app to get started.
Your Samsung account:
While not always required, being logged into your Samsung account can make the process smoother.
How to add an eSIM on Samsung S26 Ultra:-
Method 1: Adding an eSIM Using a QR Code
This is the most common method. Most carriers provide a QR code when you sign up for an eSIM.
Step 1: Open Settings
Swipe down from the top of your screen and tap the gear icon. Alternatively, find the Settings app in your app drawer.
Step 2: Navigate to Connections
In the Settings menu, tap on “Connections.” This is where all your network settings live.
Step 3: Tap on SIM Manager
You will see options for SIM cards here. Tap on “SIM Manager.”
Step 4: Select Add eSIM
Look for the option that says “Add eSIM” or “Add mobile plan.” Tap it.
Step 5: Choose Scan QR Code
Your phone will give you several options. Select “Scan QR code from service provider.”
Step 6: Scan the QR Code
Hold your phone over the QR code your carrier provided. The camera will recognize it automatically. Make sure you have good lighting and hold the phone steady.
Step 7: Follow the On-Screen Instructions
Your phone will process the QR code and display the plan details. Confirm that everything looks correct and tap “Add.”
Step 8: Wait for Activation
The phone will download and install the eSIM profile. This usually takes less than a minute. Once complete, you will see the new plan appear in your SIM Manager.
Practical example: Ahmed just moved to the UK and signed up with a local carrier. They emailed him a QR code. He followed these steps, scanned the code from his laptop screen, and had his new UK number working within two minutes.
Method 2: Adding an eSIM Using an Activation Code
Some carriers prefer to give you an activation code rather than a QR code. This is common with online-only carriers.
Step 1: Open Settings
As before, start from the Settings app.
Step 2: Navigate to Connections
Tap on “Connections” and then “SIM Manager.”
Step 3: Select Add eSIM
Tap “Add eSIM” or “Add mobile plan.”
Step 4: Choose Enter Activation Code
Instead of scanning a QR code, select the option to enter the code manually.
Step 5: Type in the Activation Code
Carefully enter the code your carrier provided. Double-check for any errors. One wrong digit can cause problems.
Step 6: Complete the Setup
The phone will process the code and add the plan. Follow the remaining instructions.
Method 3: Adding an eSIM Through Your Carrier’s App
Many carriers now let you add an eSIM directly through their official app. This is often the easiest method.
Step 1: Download Your Carrier’s App
Go to the Google Play Store and download the official app for your carrier.
Step 2: Log In to Your Account
Sign in to your account using your username and password.
Step 3: Look for eSIM Setup
In the app, find the section for managing your plan. There should be an option like “Set up eSIM” or “Add to device.”
Step 4: Follow the App Instructions
The app will guide you through the process. This usually involves confirming your identity and then sending the eSIM profile directly to your phone.
Step 5: Complete the Installation
Once the app sends the profile, your phone will handle the installation automatically.
Practical example: Leila switched to a new carrier in Australia. Instead of waiting for a QR code, she downloaded the carrier’s app, logged in, and tapped “Activate eSIM.” The app did everything automatically. She had service in under three minutes.
Method 4: Transferring an eSIM from Your Old Phone
If you are upgrading from another Samsung phone, you can transfer your eSIM to your new S26 Ultra.
Step 1: Prepare Your Old Phone
Make sure both phones are charged and connected to Wi-Fi. The old phone should be nearby.
Step 2: Open Settings on Both Phones
You need both devices ready.
Step 3: On Your New Phone
Go to Settings > Connections > SIM Manager. Tap “Add eSIM” and select “Transfer SIM from another device.”
Step 4: Follow the Transfer Process
The phones will communicate with each other. You may need to confirm on your old phone that you approve the transfer.
Step 5: Complete Setup
Once the transfer completes, your eSIM will be active on your new phone. Your old phone will lose service for that plan.
Important note: This method works best when moving between Samsung devices. If you are coming from an iPhone or other Android phone, you will likely need to use a QR code instead.
Managing Multiple eSIMs on Your S26 Ultra
One of the best features of the Samsung S26 Ultra is its ability to handle multiple eSIMs. Here is how to manage them.
Viewing Your Plans
Go to Settings > Connections > SIM Manager. You will see all your installed plans here. Each plan shows the carrier name and network status.
Switching Between Plans
Tap on any plan in the SIM Manager to change its settings. You can enable or disable a plan, choose it as your primary data connection, or assign it to specific contacts.
Setting a Default for Calls and Data
You can choose which plan handles your calls, texts, and data. This is useful if you have a work plan and a personal plan.
Practical example: Priya lives in India but travels to Singapore every month for work. She has her Indian carrier on one eSIM and a Singapore data plan on another. She sets her Indian number for calls and texts, and the Singapore plan for data. When she lands in Singapore, she switches data to the local plan and saves on roaming charges.
Adding an eSIM for International Travel
This is where eSIM really shines. Traveling with a physical SIM means finding a local store, queuing, and dealing with language barriers. With eSIM, you can buy a data plan online before you even board the plane.
Step 1: Research International eSIM Providers
Many companies specialize in travel eSIMs. Some popular ones include Airalo, Holafly, and Nomad. They offer data plans for virtually every country.
Step 2: Buy a Plan Online
Visit their website or download their app. Choose your destination, select a data allowance, and pay. You will usually receive a QR code or activation code by email.
Step 3: Add the eSIM to Your Phone
Use the QR code method described above. The eSIM will appear in your SIM Manager.
Step 4: Activate When You Arrive
Most travel eSIMs activate automatically when you connect to a local network. Some require you to enable the plan manually.
Step 5: Stay Connected
You now have local data rates without the roaming charges.
Practical example: Daniel traveled to Japan for two weeks. He bought a travel eSIM online for $20, got 10GB of data, and set it up on his S26 Ultra before he left. When he landed at Narita Airport, he turned on the eSIM and had data immediately. No need to find a SIM card store. No expensive roaming fees.
