Before purchasing from any provider, check that the plan offers genuinely unlimited data (not a small cap that throttles immediately), that the coverage map includes your specific destination, that customer support is available if something goes wrong during installation, and that refunds are available for unused eSIMs in case plans change. Holafly satisfies all of these — including a 6-month refund window on unused plans. ![Installing an eSIM takes under two minutes and works on any compatible device.](https://images.unsplash.com/photo-1512941937669-90a1b58e7e9c?w=1200&auto=format&fit=crop) FAQ ## Buying a travel eSIM Where is the best place to buy an eSIM for travel?

Can I buy an eSIM at the airport? Some airports sell physical SIM cards but eSIMs are purchased online. The advantage is you can buy and install your eSIM before you leave home — no airport lines, no language barriers, full connectivity from the moment you land. How far in advance should I buy an eSIM? You can buy an eSIM right up to minutes before departure. We usually buy ours a day or two before to make sure it's installed and tested. The QR code doesn't expire, so buying early is fine too. Is it safe to buy an eSIM online? Yes. Holafly is one of the largest travel eSIM providers in the world with over 10 million eSIMs sold and a 4.6 Trustpilot rating from 53,000+ reviews. All purchases are processed through standard secure payment systems.

Can I buy an eSIM as a gift for someone else? Yes. Holafly allows you to buy an eSIM and forward the QR code to someone else. Just make sure their phone is eSIM-compatible and unlocked before purchasing. What happens if I don't use my eSIM? Holafly offers a 6-month refund policy for unused eSIMs. If your trip gets cancelled, you can request a refund as long as the eSIM hasn't been activated. What is the difference between an eSIM and a virtual SIM card? They're essentially the same thing — both refer to digital SIM technology that doesn't require a physical card. An eSIM is the hardware standard; a virtual SIM card is a marketing term sometimes used for the same concept. Both work by downloading a carrier profile to your device. ### Related Reading [Travel Data Service Reviews](https://adamandlinds.com/reviews-travel-sim-card-providers/) [Travel SIM Provider Reviews](https://adamandlinds.com/popular-travel-sim-card-provider-reviews/) [Best Prepaid SIMs for Tourists](https://adamandlinds.com/best-prepaid-sim-cards-tourists/) [Holafly Plans Review](https://adamandlinds.com/holafly-plans-review-2/) [How to Stay Connected While Traveling Abroad](https://adamandlinds.com/how-to-stay-connected-while-traveling-abroad/) This post contains affiliate links to Holafly.
