The Samsung Galaxy S21 series is a powerhouse of features, and one often-asked question is about its eSIM capabilities. If you’re considering switching to an eSIM or simply curious about the tech, you’ve come to the right place. This article dives deep into whether the Samsung S21, S21+, and S21 Ultra support eSIM, and what that means for you. We’ll cover the benefits, how to activate it, and compare eSIM with traditional SIM cards.
Does the Samsung S21 Series Support eSIM?
Yes, the entire Samsung Galaxy S21 series, including the S21, S21+, and S21 Ultra, does support eSIM functionality. This means you can have two active phone numbers on your device—one through a physical SIM card and the other through an eSIM—or even two eSIMs if you don’t use a physical SIM card. This feature is incredibly useful for travelers, those who want separate numbers for work and personal use, or anyone looking for more flexible mobile plans.
What is an eSIM?
Before we go further, let’s understand what an eSIM is. Unlike a traditional physical SIM card that you insert into your phone, an eSIM (embedded SIM) is a digital SIM card built directly into your device. Instead of swapping out tiny plastic cards, you activate an eSIM by scanning a QR code or manually entering an activation code provided by your carrier. This makes it much easier to switch carriers, add a new line, or manage multiple plans.
How to Activate an eSIM on your Samsung S21
Activating an eSIM on your Samsung S21 is straightforward. Here’s a step-by-step guide:
- Obtain an eSIM Profile: Contact your mobile carrier or a provider that offers eSIM plans and request an eSIM profile. They will typically send you a QR code.
- Go to Settings: Open the Settings app on your Samsung S21.
- Navigate to Connections: Tap on “Connections.”
- Access SIM Card Manager: Find and tap “SIM card manager.”
- Add an eSIM: Select the option to “Add eSIM” or “Add mobile plan.”
- Scan QR Code: Use your phone’s camera to scan the QR code provided by your carrier. If you don’t have a QR code, you can enter the activation details manually.
- Follow Prompts: Your phone will guide you through the remaining steps, which may include confirming the activation and choosing your preferred settings.
- Set Preference: Designate which SIM (physical or eSIM) will be primary for data, calls, and messaging.
What if I Don’t Have a QR Code?
If your carrier doesn’t provide a QR code, they will usually give you an activation code that consists of an SM-DP+ Address and an Activation Code. You can input this information manually during step 6 above. You may also need the confirmation code from your carrier
Benefits of Using eSIM on the Samsung S21
Using an eSIM on your Samsung S21 offers several advantages:
- Dual SIM Functionality: Use two phone numbers on the same device, which is ideal for managing work and personal life or using local SIMs while traveling.
- Easy Switching: Changing carriers or plans is incredibly simple. No more fumbling with tiny SIM cards—just scan a QR code.
- Travel Convenience: Purchase a local data plan in a foreign country without having to physically remove your home SIM.
- Environmentally Friendly: Less plastic and fewer SIM cards mean a smaller environmental footprint.
- Device Security: With embedded technology, no removable SIM cards means one less thing to worry about losing.
“The flexibility of eSIM is a game-changer for anyone who juggles multiple phone numbers or travels frequently. It simplifies the entire process of managing mobile connections,” says Dr. Anya Sharma, a mobile tech specialist.

Samsung S21 eSIM Compatibility: Common Questions
Can I use two eSIMs on my Samsung S21?
While the S21 series supports dual SIM capabilities with one physical SIM and one eSIM, it does not typically support two active eSIMs simultaneously. You can store multiple eSIM profiles on your phone, but only one can be active alongside a physical SIM. However, some carriers may offer ways to activate dual eSIM through software updates. So, consult with your specific provider.
Is my Samsung S21 carrier locked for eSIM use?
Just like with physical SIM cards, your Samsung S21 may be carrier locked if you purchased it through a specific provider. You’ll have to ensure that your phone is unlocked to use eSIM plans from other carriers. If your device is locked you will need to consult your service provider for unlocking options.
How much data can I use with an eSIM?
The amount of data you can use depends entirely on your eSIM plan. Data limits, roaming charges, and other plan details are managed by your mobile provider, not the phone itself.
“Understanding the specific limitations of your eSIM plan is crucial. Always read the fine print and choose a plan that aligns with your usage needs.” explains Johnathan Lee, a mobile plan analyst.
What happens if I lose my Samsung S21 with an eSIM?
If you lose your device, you need to contact your mobile carrier to deactivate the eSIM, just like you would do with a physical SIM card. They can then issue a new eSIM profile for your new device.
Can I use my Samsung S21 eSIM with a smartwatch?
Generally, eSIM profiles for phones are different than those used on smartwatches. You would need to obtain a new eSIM profile specific to your smartwatch if it supports cellular connectivity.

The Samsung Galaxy S21 series’ eSIM capability offers significant advantages, especially for those needing dual SIM functionality or simplified international travel. Whether you’re switching carriers, using multiple lines, or looking for an eco-friendly solution, the eSIM on your S21 is a handy tool. By understanding how to activate and manage your eSIM, you can unlock the full potential of your smartphone.
