How to Download and Use eSIM on Samsung and iPhone 12 Pro

Installing an eSIM on the iPhone 12 Pro is straightforward thanks to Apple’s integrated eSIM download options in iOS. As a digital SIM solution, eSIM eliminates the need for a physical card while supporting dual‑SIM functionality. This guide walks you through each stage, from initial setup to activation, with clear, concise instructions tailored for beginners.

What You’ll Need

  • Internet connection
  • Provider QR code or activation code
  • Apple ID (if prompted)

Step‑by‑Step Installation

  • Open Settings on your iPhone 12 Pro running iOS 16 or later.
  • Tap Cellular (in some regions, this appears as Mobile Data).
  • Select Add eSIM. On older builds you may see Add Cellular Plan.
  • Choose Download a Carrier Plan to fetch settings automatically, or tap Use QR Code to scan manually.
  • Point the camera at your carrier’s QR code. If scanning fails, enable Camera access under Settings > Privacy > Camera.
  • Confirm the plan by tapping Add Cellular Plan, then assign a label (e.g., Primary, Business).
  • Return to Settings > Cellular to view your eSIM profile and enable Data or Voice permissions.

Common Troubleshooting Tips

  • If “Add eSIM” is missing, update to the latest iOS and restart your device.
  • If the QR scan fails, clean your camera lens or enter the SM‑DS and activation code manually.
  • If activation errors occur, ensure your plan supports eSIM provisioning with your provider.
  • On iOS 16.2 some users report dual‑SIM labels resetting after reboot—reapply custom names in Settings.
  • Error code 80110017 may appear briefly; toggle Airplane Mode off and on before retrying.

For TapSim purchases, all instructions arrive by email immediately after purchase. That email includes your unique QR code and activation details. Whether you’ve used esim android samsung setups or other platforms, the activation link in your inbox simplifies the process. You’ll scan the provided QR code or paste the activation URL in Settings > Cellular > Add eSIM.
