Contact Simsimsim
One email address for orders, eSIM problems, refunds and questions.
Email: support@simsimsim.app. You can write in English, Russian or Ukrainian. We aim to answer within 1-2 business days.
What to include
The more of this you send, the faster we can solve it:
- The email address you used for the order and your order ID.
- The destination and the plan you bought.
- Your phone model and iOS or Android version.
- For connection problems, a screenshot of Settings, Cellular (or Mobile network), with the eSIM line visible.
- For refunds, say whether you installed the eSIM. The refund policy has different windows for “never installed”, “installed but not activated” and “activated”.
Before you write
Many problems have a quick fix. These guides cover the common ones:
- eSIM not connecting: no signal or no data after install.
- QR code not working: scan errors and manual entry.
- APN settings: when you need them and how to set them.
- Does my phone support eSIM?: check before you buy.
Refunds
Send your order ID and the reason to the address above. The steps and time windows are on the refund page. Please contact us before opening a chargeback; it is much faster to solve it with us.
