Frequently asked questions

How do I install this eSIM?

After purchase you will receive an email with a QR code. Open your phone Settings, go to Mobile Data or Cellular, tap Add eSIM, and scan the code. The whole process takes under a minute over Wi-Fi.

Is my phone compatible?

Most phones from 2019 onwards support eSIM. iPhone XS and newer, Google Pixel 4 and newer, and Samsung Galaxy S20 and newer all work. Check your phone Settings for an eSIM option to confirm.

Can I top up this plan?

If the plan supports top-up, you can add more data from your My eSIMs page in seconds. The extra data is added to your existing eSIM profile — no need to install a new one.

What is the refund policy?

Read our Japan travel guide →

Two scenarios qualify for a full refund: (1) the QR code has never been installed on any device, or (2) the eSIM cannot be activated due to a fault on our side. Once installed, the eSIM counts as used under UK Consumer Contracts Regulations 2013 and is no longer refundable. The 14-day cooling-off right is waived at checkout under reg. 37 because eSIMs are delivered immediately. Contact us within 30 days of purchase to request a refund — see /refunds for the full policy.
