10 Tech How-To

How to Set Up eSIM on iPhone XS and XR

Guide 10-33313 · Updated · Step by step

This guide walks you through activating an eSIM on your iPhone XS or iPhone XR, letting you use a second cellular plan without a physical SIM. You’ll need a carrier that supports eSIM and a QR code or activation details from them. Follow the steps below to get your eSIM up and running.

What You’ll Need

  • An iPhone XS or iPhone XR with iOS 12.1 or later (update to the latest iOS if possible).
  • A carrier that supports eSIM on these models (most major carriers do).
  • An eSIM activation card, QR code, or activation details from your carrier (often provided via email or app).
  • A Wi-Fi or cellular connection to complete the setup.

Step-by-Step

  1. Check carrier support: Contact your carrier or visit their website to confirm they support eSIM on iPhone XS/XR and request an eSIM activation. They’ll provide a QR code or an app to install the plan.
  2. Back up your iPhone: Although not required, back up to iCloud or your computer before making changes to cellular settings.
  3. Update iOS: Go to Settings > General > Software Update and install any available updates to ensure eSIM features work correctly.
  4. Open the Camera app: If you have a QR code, open the Camera app and point it at the code. A notification will appear—tap it to start setup.
  5. Alternatively, go to Settings: If you have an activation code or a carrier app, go to Settings > Cellular > Add Cellular Plan.
  6. Scan or enter details: Scan the QR code with the camera, or manually enter the details if prompted (the carrier will give you a confirmation code or SM-DP+ address).
  7. Label your plan: After the plan is added, you’ll be asked to assign a label (e.g., Personal, Business, Travel). Choose one or create a custom label.
  8. Set default line: Choose which line to use as your default for calls, messages, and data. You can change this later in Settings > Cellular.
  9. Finish activation: Follow any on-screen instructions to complete activation. Your carrier may require you to restart your iPhone or wait a few minutes for the plan to become active.
  10. Verify: Check Settings > Cellular to see both plans listed. Make a test call or send a message to confirm the eSIM works.

Common Mistakes

  • Scanning the QR code with the wrong app (e.g., a third-party scanner) instead of the Camera app.
  • Entering the SM-DP+ address incorrectly—double-check for typos.
  • Forgetting to set a default line, which can cause confusion about which number is used.
  • Removing the physical SIM before the eSIM is fully activated.
  • Not having a Wi-Fi connection during setup, which can cause activation failure.

Tips

  • Keep your eSIM activation QR code or details in a safe place—you may need them again if you erase your iPhone.
  • If you travel, you can add a local eSIM plan temporarily without removing your primary line.
  • Use the “Cellular Plans” section to manage data usage per line; you can set one line to use data only when the other is unavailable.
  • If your carrier uses an app for activation, install it before starting; it may handle the setup automatically.

Troubleshooting

eSIM not activating after scanning: Restart your iPhone, then go to Settings > Cellular > Add Cellular Plan and try again. If it still fails, contact your carrier to confirm the eSIM is provisioned and not already used.

“Unable to Add Cellular Plan” error: Ensure your iPhone is not carrier-locked to a different carrier. Go to Settings  General  About and check “Carrier Lock.” If it’s locked, you’ll need to contact the original carrier to unlock it.

No service after activation: Turn off Cellular Data, wait a few seconds, then turn it back on. Also, check that the eSIM line is enabled under Settings > Cellular—toggle it off and on.

eSIM disappeared: Go to Settings > Cellular and tap “Add Cellular Plan” again. If you have the QR code, scan it again. If not, contact your carrier to re-send the activation details.

Can’t make calls on the eSIM line: Make sure the line is set as the default for calls, or manually select it when dialing. Also, check that “Cellular Data” is set to the correct line if you’re using data on the other line.

Frequently Asked Questions

Can I use eSIM and a physical SIM at the same time?

Yes, iPhone XS and XR support Dual SIM (one physical SIM and one eSIM). Both can be active simultaneously for calls and data, though only one can use cellular data at a time.

Will my eSIM work if I erase my iPhone?

No, erasing your iPhone removes the eSIM profile. You’ll need to re-add it using the original QR code or activation details. Some carriers allow you to re-download the plan from their app.

Can I transfer my eSIM to a new iPhone?

Yes, but you must remove the eSIM from the old iPhone first (Settings > Cellular > tap the plan > Remove Cellular Plan). Then, on the new iPhone, add the plan using the same activation method.

Is eSIM free?

Most carriers do not charge extra for eSIM activation, but some may have a fee. Check with your carrier for specific costs.

Can I use eSIM while traveling internationally?

Yes, you can add a local eSIM plan from a carrier in the country you’re visiting, as long as your iPhone is unlocked. This can be cheaper than roaming.

What if my carrier doesn’t support eSIM?

If your carrier doesn’t support eSIM, you’ll need to use a physical SIM. Alternatively, you can switch to a carrier that does support eSIM.
