Frequently asked questions

How do I install my eSIM?

Your activation link appears instantly after purchase - just tap it on your phone. We also email everything, so you can install later if needed. Installation takes less than a minute.

I accidentally deleted my eSIM - can I reinstall it?

Contact our support team with your order number. We can usually provide a new activation link or QR code. Note that some eSIMs can only be installed once, so a new plan may be required.

Do I need to unlock my phone to use an eSIM?

Your phone must be carrier-unlocked to use a third-party eSIM. If you bought your phone outright or finished your contract, it's usually unlocked. Contact your carrier if unsure.

How is an eSIM different from a physical SIM card?

An eSIM is embedded in your device and activated digitally - just tap a link or scan a code. You don't need to swap cards or visit a store. You can have multiple eSIM plans stored on one phone and switch between them instantly.

Can I install my eSIM before traveling?

Yes, and we recommend it. Install the eSIM while you have WiFi at home using the activation link. Check the product details whether your plan starts after installation or at first connection in your destination.

Which iPhone models support eSIM?

iPhone XS, XR, and all newer models support eSIM. This includes the entire iPhone 11, 12, 13, 14, 15, 16, and 17 series. iPhone X and earlier do not support eSIM.
