Refund policy

Last updated: August 2026

1. Digital Product Delivery

ZemSim eSIMs are digital products delivered instantly by email right after your purchase. Because there is no physical item to send back, returns do not apply — but we do offer refunds for eligible cases, as described below.

2. Our Guarantee

We stand behind every eSIM we sell. If your eSIM fails to install on a compatible device, or the data plan does not work as described, contact us within 30 days of purchase and we will either replace your eSIM or issue a full refund.

3. When We Offer a Refund

You are eligible for a full refund if:

• The eSIM cannot be installed on your device due to a compatibility issue.
• The data service does not activate or does not work in the country you purchased it for.
• The eSIM was never delivered to your email address.
• You purchased the wrong country or plan and contact us before using the eSIM.

4. How to Request Help

Email us at hello@zemsim.com with your order number and a short description of the issue. We respond within 24 hours. Including your phone model helps us resolve your issue faster.

5. No Partial Refunds

Because each eSIM is a one-time digital product, we do not offer partial refunds or refunds for partially used data.

6. Chargebacks

If you believe there is an error with your order, please contact us before disputing the payment with your bank. We will resolve any issue quickly — usually on the same day.
