Where to Buy eSIMs for Unlimited Data Abroad
Buying a travel eSIM sounds complicated until you do it once. Here's exactly where to buy, what to look for, and how to get 5% off your order.
Buying an eSIM is one of those things that sounds complicated until you do it once, and then you wonder what you were worried about. The whole process takes under five minutes. But there are enough providers and enough conflicting advice out there that it's worth cutting through the noise and being direct about where to buy, what to look for, and what to avoid.
We've been buying travel eSIMs for three-plus years, across 33 countries, and we have a clear answer on where to get them.

What to Look for When Buying a Travel eSIM
Not all travel eSIMs are equal. 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.

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.
