Step-by-step setup

Install your eSIM in under 2 minutes.

Whichever device you carry, the process is the same: open Settings, scan your QR code, toggle data on at your destination. Pick your platform below for screen-by-screen instructions.
iPhone instructionsAndroid instructions

Install on iPhone.

Requires iOS 14 or later. Make sure your phone is connected to Wi-Fi before you start.

  1. 1

    Open Settings

    Settings → Cellular → Add eSIM

    On iOS 16+ tap Set Up eSIM. On iOS 14–15, tap Add Cellular Plan. Your phone may take a few seconds to load the eSIM setup screen.

    Tip: If you don’t see “Add eSIM,” your iPhone may be carrier-locked. Contact your home carrier to unlock it.

  2. 2

    Pick your method

    Choose “Use QR Code”

    If the camera won’t focus, tap Enter Details Manually and paste the SM-DP+ address and activation code from your confirmation email.
  3. 3

    Scan

    Scan the QR from your confirmation email

    Open the email on a laptop or second device, then hold your phone steady about six inches away. The profile downloads in about 20 seconds.

    Tip: Can’t open the email on a second screen? Forward it to a friend, or paste the activation code manually — same result.

  4. 4

    Label it

    Name your plan something memorable

    We recommend esimple Japan (or whichever country) — it makes finding the right line easy when you switch between data plans on a multi-country trip.
  5. 5

    Activate

    When you land, turn on the line and Data Roaming

    Settings → Cellular → tap your esimple plan → toggle Turn On This Line and Data Roaming. Then set Cellular Data to esimple.

    Tip: Data Roaming sounds scary, but esimple has zero roaming fees — your iPhone just needs that flag set to use a foreign network.

Install on Android.

Wording varies slightly by manufacturer. Samsung and Pixel are the most common — instructions for both are below.

  1. 1

    Open Settings

    Settings → Network & Internet → SIMs → +

    Samsung: Settings → Connections → SIM manager → Add eSIM. OnePlus / Oppo: Settings → Wi-Fi & network → SIM & network.
  2. 2

    Choose download

    Tap “Download a SIM instead?”

    Allow camera permission when prompted. Samsung users will see “Add using QR code” instead.
  3. 3

    Scan + confirm

    Scan the QR, then tap Download

    The profile downloads in about 20 seconds. Tap Settings after install completes — your eSIM appears in your SIM list.
  4. 4

    Label it

    Give the eSIM a clear name

    Most Androids call it “SIM nickname.” Use the destination country so you can tell it apart from your home SIM at a glance.
  5. 5

    Activate

    Land, then set esimple as your data SIM

    SIMs → tap esimple → enable Use SIM, set Mobile data to esimple, and enable Roaming for the esimple line specifically.

Troubleshooting common issues.

If you hit one of these, you’re not alone — most can be fixed in under a minute.

  • The QR code won’t scan

    Open your email on a second device and scan from that screen. Or paste the SM-DP+ address and activation code manually from your confirmation email — same result.

  • Profile downloads but won’t activate

    You need to be in the destination country — most carriers won’t release the profile until your phone touches a local network. Wait until you’ve landed, then toggle Data Roaming on.

  • “No service” after I land

    Restart your phone first. If still no service, check that Data Roaming is enabled for the esimple line specifically — not just your default line.

  • I deleted the eSIM by mistake

    Contact support with your order ID — we can re-issue the same profile within a few hours, free of charge. Most eSIMs allow up to three re-installs.
