Important — use in the United Kingdom: we have received reports that this eSIM does not work correctly in the United Kingdom. We are investigating, so please take this into account if you are considering using it there.

• After you arrive, switch roaming on in your device settings.
• Covered countries and regions are listed on Rakuten Mobile’s official site.

• The validity period can be extended. Extensions are sold in 12-month units only — see the extension product.

Before you start (required)

• A Wi-Fi connection is required. Please have Wi-Fi available when you set up.
• To scan the QR code you need a second device to display it, or a printed copy.

While you are setting up

• If you are asked for a password during setup, enter the passcode set on your own device.
• The APN is configured automatically once the eSIM is installed, but some Android devices require the APN to be set manually.
• Automatic detection may not work on an older OS version, so we strongly recommend updating to the latest version first.

On iOS

• On iOS 17 or later you can save the QR code as an image and choose “Use Photo” when installing.

Installing

• This eSIM cannot be reinstalled, so please install it with a stable Wi-Fi connection.

When a reissue is needed

You need to apply for a reissue in these cases:

• The installation failed.
• You deleted the eSIM by mistake.
• You want to move it to another device, for example after changing phones.

Because of how eSIM works, the profile cannot be set up on any device other than the one it was first installed on.

Where to apply

eSIM reissue request form

• Only eSIMs purchased from our store are eligible.
• Make sure the MSN (phone number) of the eSIM is correct — we cannot process a request with the wrong number.
• We cannot accept a reissue during the final month of the validity period.

Important

• Once the reissue process starts, all services on your current eSIM stop.
• A reissue is free, but it takes two to three weeks to issue — over a month when we are busy.
