If you have a Samsung Galaxy from the last few years, you almost certainly already have an integrated eSIM and don't know it. In this guide, we explain how to check your model's compatibility, install your eSIM step-by-step from the SIM Manager, activate it with a QR code, and configure it as a data line for your next trip. All in less than 5 minutes.
Which Samsung Galaxy models have eSIM?
Samsung massively introduced eSIM in its Galaxy range starting in 2021. Unlike the iPhone guide, where virtually all models since the XS are compatible, in Samsung there are some important exceptions depending on the target market.
This is the list of the most common eSIM-compatible models among travelers:
| Series | Models | eSIM |
|---|---|---|
| Galaxy S21 | S21, S21+, S21 Ultra | ✅ |
| Galaxy S22 | S22, S22+, S22 Ultra | ✅ |
| Galaxy S23 | S23, S23+, S23 Ultra, S23 FE | ✅ |
| Galaxy S24 | S24, S24+, S24 Ultra, S24 FE | ✅ |
| Galaxy Z Fold | Z Fold 3, Z Fold 4, Z Fold 5, Z Fold 6 | ✅ |
| Galaxy Z Flip | Z Flip 3, Z Flip 4, Z Flip 5, Z Flip 6 | ✅ |
| Galaxy Note 20 | Note 20 Ultra | ✅ |
How to check if your Samsung has eSIM? The quickest way is to go to Settings > Connections > SIM Manager. If you see the "Add mobile plan" or "eSIM" option, your phone is compatible. If only the physical SIM appears, your model or regional variant may not support it. You can also consult the complete list of eSIM compatible mobiles for more details.
How to install eSIM on Samsung Galaxy
Before you start, make sure you have the following:
- An eSIM-compatible Samsung Galaxy (see table above)
- Internet connection (WiFi or mobile data from your physical SIM)
- Your PuraSim eSIM QR code (you will receive an email with it after purchase)
- Sufficient battery life — we recommend more than 30%
The installation process on Samsung Galaxy is surprisingly simple and is carried out entirely from the system settings, without the need for external applications:
- Open Settings on your Samsung Galaxy.
- Go to Connections.
- Tap SIM Manager.
- Select Add mobile plan (or "Add eSIM" depending on the One UI version).
- The system will ask you to scan a QR code — we will detail this step in the next section.
- Follow the on-screen instructions to confirm the installation.
- Assign a name to the profile (e.g., "PuraSim Europe") to easily identify it.
The entire process should not take more than 3-5 minutes. Once installed, the eSIM will appear in your SIM Manager next to your physical card, and you can activate or deactivate it whenever you want.
Activate eSIM on Samsung Galaxy with QR code
The most common method to activate a travel eSIM like PuraSim is via QR code. When you get to the "Add mobile plan" step in the previous section, Samsung offers you several options:
- Select Scan QR code.
- Point the camera at the QR code that you will find in the PuraSim confirmation email.
- The system will automatically download the eSIM profile.
- Confirm the installation when the system prompts you.
- Choose when you want to activate the eSIM: you can activate it now or later from the SIM Manager.
- If you have chosen to activate it, select whether you want to use it for data, calls, or both.
Manual alternative (SM-DP+): If the QR code doesn't work or you prefer to enter the data manually, PuraSim also provides you with the SM-DP+ activation code. On the "Add mobile plan" screen, look for the Enter activation code option and enter the SM-DP+ server address and the activation code that you will find in your email. This method is especially useful if you are trying to install the eSIM from another device that already has the camera occupied.
Configure eSIM as the main data line
Once the PuraSim eSIM is installed, the next step is to configure it correctly so that all your travel data traffic goes through it — and not through your Spanish SIM, which could generate roaming charges.
- Go to Settings > Connections > SIM Manager.
- Tap Mobile data.
- Select your PuraSim eSIM as the active data line.
- Go back to the SIM Manager and tap Data roaming.
- Activate data roaming for the PuraSim eSIM — this is essential for it to work abroad.
What about calls? We recommend keeping your physical Spanish SIM as your call and SMS line. This way, you will continue to receive calls on your usual number while using PuraSim data. To configure it, go to SIM Manager > Calls and select your physical SIM.
With this dual SIM configuration, you only pay for the data you use with PuraSim, with no surprises on your usual operator's bill. It is the smartest way to travel connected.
Frequent problems when installing eSIM on Samsung
Although the process is simple, sometimes small obstacles arise. Here are the 5 most common problems and how to solve them:
1. The "Add mobile plan" option does not appear
Cause: The model is from South Korea or China, or the current operator has blocked the eSIM function.
Solution: Confirm the origin of the device (Settings > About phone > Status > IMEI). If the IMEI starts with certain prefixes from those markets, the hardware does not support eSIM. If the problem is the operator, call your company to request that they unlock the eSIM.
2. The QR code does not scan correctly
Cause: Poor lighting, dirty screen, or low-quality QR code printing.
Solution: Make sure you have good light, clean the camera, and increase the brightness of the screen where the QR is displayed. Alternatively, use the manual SM-DP+ activation code that you will find in the PuraSim email.
3. The eSIM installs but does not connect to data
Cause: Data roaming is not activated or the eSIM is not selected as the data line.
Solution: Go to Settings > Connections > SIM Manager > Mobile data and select your PuraSim eSIM. Then activate "Data roaming" for that line.
4. Error "Cannot download profile"
Cause: Connection problem during download or QR code already used.
Solution: Make sure you have a stable WiFi connection. Some eSIM profiles can only be scanned once — if the code has already been used, contact PuraSim support to get a new activation code.
5. The eSIM disappears after updating the system
Cause: In some cases, One UI updates can affect saved eSIM profiles.
Solution: Always save the QR code or SM-DP+ code in a safe place before updating. If the eSIM disappears, reinstall it from the SIM Manager using the saved code. If the profile is no longer valid, contact PuraSim.
Conclusion
Installing an eSIM on Samsung Galaxy is a quick and simple process that any traveler can do in a few minutes from the SIM Manager. The key is to choose a compatible model, activate the eSIM before the trip with WiFi, and configure it correctly as a data line with roaming activated. With PuraSim, you have coverage in more than 100 destinations from the moment you land, without contracts or permanence.
