Do I need Wi-Fi to install the eSIM?

Installing an eSIM requires downloading the eSIM profile from the carrier to your device. This process needs a stable internet connection to ensure the download completes successfully and your eSIM is configured correctly.

Wi-Fi is recommended

• Using a stable Wi-Fi connection is the most reliable way to install your eSIMNum profile.
• Wi-Fi reduces the risk of installation errors caused by slow or unstable networks.
• It’s especially recommended to install your eSIM at home or in a location with a strong and stable connection before you travel.

Mobile data can also work

• If you do not have access to Wi-Fi, you can use a stable mobile data connection to install your eSIM.
• Make sure your mobile data signal is strong and consistent to prevent incomplete installation or download errors.

Why a stable connection matters

• The eSIM profile contains carrier information, authentication data, and network settings.
• Any interruption during download or installation may result in:
  • Installation failure
  • QR code or activation code errors
  • Partial installation that prevents your eSIM from working
