Ready before you go.

A step-by-step guide to installing your eSIM. Always follow your supplier’s package-specific instructions first.

Before installation

Connect to Wi-Fi, check device compatibility, and confirm when the plan’s validity begins. Have the supplier’s installation details ready on another screen, or use its supported manual or one-tap method.

Install on iPhone

  1. Open Settings → Cellular (or Mobile Data) → Add eSIM.
  2. Choose Use QR Code and scan the code supplied with your order. Use Enter Details Manually if that option is provided.
  3. Follow the prompts and label the line so you can recognize it, such as “Travel data”.
  4. Select the travel eSIM for mobile data when you are ready to use it. Follow supplier guidance on data roaming and activation.
  5. Keep data roaming off on your home SIM if you want to avoid home-carrier roaming data charges. Check automatic data switching too.

Not connecting yet?

  1. Confirm that you are in a covered destination and the plan is valid.
  2. Check that the eSIM is enabled and selected for mobile data.
  3. Follow supplier instructions for roaming, network selection, and APN. Do not guess settings.
  4. Try toggling airplane mode, then contact supplier support if the issue remains.

Do not delete the eSIM as a troubleshooting step. Reinstallation may not be supported. Ask the supplier for help ↗ (opens in a new tab).
