How to Install an eSIM on iPhone — Step-by-Step Guide

Installing an eSIM on an iPhone takes less than two minutes. Here's the complete step-by-step process for all supported models (iPhone XS and later).

Before You Start

  • Your iPhone must be unlocked (not carrier-locked)
  • You need an active Wi-Fi or mobile data connection
  • Have your eSIM QR code ready (from SIMPal or your carrier)
  • Make sure your iOS is up to date

Method 1: Scan a QR Code (Most Common)

  1. Open Settings on your iPhone
  2. Tap Mobile Data (or "Cellular" in some regions)
  3. Tap Add eSIM
  4. Tap Use QR Code
  5. Point your camera at the QR code provided by SIMPal or your carrier
  6. Tap Continue on the confirmation screen
  7. Choose a label for the eSIM (e.g. "Travel — Japan") and tap Continue
  8. Choose your default line for calls, texts, and data, then tap Done

Method 2: Enter Details Manually

If you can't scan the QR code, tap Enter Details Manually after step 3 and type in the SM-DP+ Address and Activation Code provided by your carrier.

Method 3: iPhone 14+ (eSIM Transfer / Direct Setup)

iPhone 14 and later in the US are eSIM-only. When setting up a new device, iOS will offer to transfer your eSIM from your previous iPhone automatically if both phones are nearby.

After Installation: Set Your Default Lines

With dual SIM enabled you'll be asked which line to use for:

  • Default line for calls and texts (usually your home SIM)
  • Mobile data (select your travel eSIM for local rates)
  • iMessage and FaceTime

You can change these any time in Settings → Mobile Data.

Troubleshooting

If activation fails, ensure your iPhone is connected to Wi-Fi and that the QR code hasn't been used before. Each SIMPal QR code is single-use. Contact SIMPal support in-app if the issue persists.
