How to Add eSIM on Samsung Galaxy S20

Learning how to add esim on your Samsung Galaxy S20 is straightforward with a few simple steps. This guide will walk you through esim installation on the One UI interface, making the process clear and concise. Whether you’re switching carriers or activating a secondary line, follow these instructions to ensure a smooth setup.

What You’ll Need

  • Internet connection
  • Carrier QR code or activation code
  • Samsung account (if prompted)

Step-by-Step Installation

  • Open Settings from your home screen or app drawer.
  • Tap Connections, then select SIM card manager.
  • Choose Add mobile plan. On some One UI versions this may appear as Download a SIM instead.
  • Use your camera to scan the QR code provided by your carrier. If scanning fails, tap Enter details manually and input the SM-DP+ address and activation code.
  • Confirm the plan name when prompted. You can label this profile (for example, “Work” or “Travel”).
  • When the profile appears, tap it and select Turn on this SIM to activate your eSIM line.
  • Return to Connections > SIM card manager to set data and calling preferences between profiles.

Common Troubleshooting Tips

  • If “Add mobile plan” is missing, update your system software under Settings > Software update and restart the device.
  • If the QR code scan fails, ensure your camera lens is clean or switch to manual entry of the activation details.
  • If activation errors occur, verify that your plan supports esim installation and that the code is valid.
  • If you see error code 900 or network installation errors, clear network settings under Settings > General management > Reset > Reset network settings.
  • For QR code issues unique to the Galaxy S20, request a new activation code from your provider’s eSIM portal if the original code times out.

Installing via TapSim

When you purchase an eSIM through TapSim, all instructions are emailed immediately after purchase. The email includes a QR code and activation details. Simply follow the same steps above, but when you reach the QR code scan stage, use the TapSim email attachment to complete activation.

Conclusion

This guide has covered each phase of your esim set up on the Samsung Galaxy S20. By preparing your QR code, following the exact menu paths, and using the troubleshooting tips provided, you can add a secondary line or switch carriers quickly. Enjoy the flexibility of eSIM on your Galaxy S20.
