Frequently Asked Questions

An eSIM is a digital SIM built into a compatible device. It lets you add a mobile data plan without inserting a physical SIM card. Your device must support eSIM and be network or carrier unlocked. See our Compatible Devices guide before purchasing.

Choose a destination, select a suitable data plan and complete your order. Once the order is successfully processed, you receive the information needed to install your eSIM. See the complete process on How It Works, or start at All Destinations.

Check your exact model, region and carrier variant in the manufacturer’s specifications, and look for an option to add an eSIM or mobile plan in your device settings. Model names alone are not always enough because regional versions can differ. Use our Compatible Devices page as a starting point.

Yes. Your device must be network or carrier unlocked so it can use an eSIM plan from another provider. If you are unsure, check with the carrier that supplied your phone before buying.

Our current integration sends the activation email after your WooCommerce order reaches Completed status and the eSIM processing succeeds. The email is not sent simply because checkout has started. If your order is completed but you cannot find the message, check your spam or junk folder and then contact us.

The activation email generated by our current integration contains your order information, ICCID, an LPA code and a QR code made from that installation data. It may also show plan information when available. Keep this email safe and follow the instructions supplied with your eSIM.

Open the mobile or cellular settings on your compatible phone, choose the option to add an eSIM and scan the QR code supplied in your activation email. Menu names vary by device and operating-system version. Follow our step-by-step Installation Guide.

Check the instructions and conditions for your specific plan before installing it. Activation rules can vary between plans, countries and network partners, so do not assume that every package should be installed at the same time. If the timing is unclear, contact us before installation.

The start of the validity period is plan-specific. Depending on the package and network partner, it may begin after purchase, after installation, on the first connection to a supported network, or when several conditions are met. Review the information supplied for your plan and ask us before installation if anything is unclear.

Yes. Use a stable Wi-Fi or internet connection while adding and downloading the eSIM profile. Once installation is complete, follow the supplied instructions to select the eSIM for mobile data when appropriate.

Many compatible phones can keep a physical SIM active alongside an eSIM, but this depends on the exact device and its dual-SIM capabilities. Check which line is selected for calls, messages and mobile data. Your regular carrier may charge for services used through the physical SIM.

Retesim travel eSIM packages supplied through the current Yesim integration are data-only and do not provide a traditional mobile number for regular cellular calls or SMS. You can use internet-based calling and messaging apps with the data connection. Where your phone supports it, you may keep your physical SIM for normal calls and messages.

The current package will no longer provide data after its included allowance has been used. Available next steps can depend on the plan, so we do not promise that every package supports a top-up. You can browse available eSIM plans or contact us for help.

Do not delete your eSIM profile if you still intend to use it. Reinstallation and transfer are not guaranteed, an eSIM normally cannot be active on two devices at the same time, and support can vary by provider and plan. Contact us before deleting the profile, resetting the phone or moving to another device.

First confirm that your exact device supports eSIM and is unlocked, that you had a stable internet connection during installation, and that the new eSIM is selected for mobile data when appropriate. Review the supplied instructions and our Installation Guide. If the problem continues, contact us with your order number, device model and destination so we can check the specific plan.

Refund eligibility depends on the Retesim Refund Policy, the state of your order and whether the eSIM or data plan has already been installed, activated or used. Review the policy and contact us as soon as possible, preferably before installing or using the eSIM. The published Refund Policy takes precedence over this general FAQ answer.
