How to Activate eSIM on Samsung Galaxy Z Flip3 5G

What You’ll Need

  • Internet connection
  • Carrier QR code or activation code
  • Google account for setup prompts

Gather the items listed above before you begin. Ensure you have a stable internet connection over Wi‑Fi or mobile data to fetch the activation profile without interruption.

The Samsung Galaxy Z Flip3 5G is one of the most innovative models from Samsung, built specifically for modern connectivity. As one of the top esim enabled phones on the market, it offers secondary lines without a physical SIM card slot. This guide will help beginners through a straightforward process tailored to this device.

Below, you’ll find concise esim instructions that take you through each submenu in One UI 3.1 on Android 11. These steps include any alternate names or quirks found on the Z Flip3 5G, ensuring clarity for first-time users.

If you’re new to digital SIM technology, you may be asking what is esim? An eSIM is a programmable SIM embedded in your device, allowing you to activate a mobile plan without a traditional card. Let’s begin.

Adopting eSIM on your Flip3 5G saves space for a second physical SIM and increases flexibility when traveling. The built‑in SIM eliminates the risk of losing small cards and speeds up carrier switching.

Step-by-Step Installation

  • Open Settings on your Samsung Galaxy Z Flip3 5G.
  • Tap Connections in the main menu.
  • Select SIM card manager under Connections.
  • Tap Add mobile plan (or Download SIM profile on some One UI builds).
  • Use your camera to scan the QR code sent by your carrier.
  • If the camera fails, choose Enter code manually and type the activation details.
  • Follow on-screen prompts to label the new profile and tap OK to confirm.

Once the download completes, the new plan appears in SIM card manager. You can set it as the default line for calls, messages, or data under the same menu.

Common Troubleshooting Tips

  • If “Add mobile plan” is missing, update One UI and reboot the device.
  • If the QR scan fails, clean the camera lens or select Enter code manually.
  • If activation errors occur, ensure your plan is eSIM-enabled with your provider.
  • Clear the cache of the SIM card manager app if you see error code 21 during installation.
  • Toggle Airplane mode on and off if mobile data does not activate after installation.

These tips cover the most common issues. If you continue to see errors, verify the eSIM profile status under SIM card manager and contact your carrier for additional support.

Installing via TapSim

All TapSim customers receive detailed instructions by email immediately after purchase. This message contains a QR code, activation code, and a link to additional setup details. Simply follow the same onscreen steps to scan the QR or enter the code manually when prompted under Add mobile plan.

TapSim integrates seamlessly with Samsung’s mobile data settings. You only need to download the profile directly from your email link or scan the provided code.

After activation, you can manage profiles in SIM card manager by tapping the eSIM entry and selecting preferred usage options, such as data allocation or call routing.

Conclusion

Installing an eSIM on the Samsung Galaxy Z Flip3 5G requires only a few simple steps and minimal equipment. By following this guide and using the troubleshooting tips, you can activate a secondary line without a physical SIM. For further assistance, consult your carrier’s support resources or Samsung’s online documentation.
