Send a correction or editorial question

Email hello@esimjapanguide.com about this guide, including price corrections, unclear wording, accessibility problems or privacy questions.

For a correction, include the page URL, the provider and package involved, and a link to the current provider listing. Explain which detail differs: data allowance, validity, network, hotspot terms or checkout price. A dated screenshot can help explain a temporary promotion; remove account details, order numbers and installation codes before sending it.

Our comparison methodology explains how we match packages and distinguish price checks from editorial updates. The About page explains who runs the guide, and our privacy policy describes information involved in contacting us.

Help with an eSIM you bought

For an installation problem, refund, activation error or account issue, contact the provider through the support route in your order confirmation. This guide cannot access a provider’s customer account or change a purchased package.

Keep your order confirmation and note the exact error message, device model and settings involved. Share that information with the provider’s support team through its official channel. Do not send payment-card details, passwords or an eSIM QR code to this guide. Our Japan eSIM FAQ covers general setup checks you can review alongside your provider’s instructions.
