FAQ

Common questions

Everything you need to know before buying.

An eSIM is a digital SIM built into your phone. Instead of inserting a plastic card, you simply tap an activation link or scan a QR code to activate your mobile data plan. It works exactly like a regular SIM, just without the physical card.

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.

Instantly. Your activation link and backup QR code appear on screen seconds after purchase. We also send everything by email so you have it saved for later.

Yes. Most eSIM-compatible phones are dual-SIM, meaning you can use your physical SIM for calls and texts from home while using the eSIM for mobile data abroad.

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.

We accept Apple Pay, Google Pay, PayPal, Klarna, Amazon Pay, all major credit and debit cards, and more. All payments are processed securely.
