how do eSIMs actually work for travel?

Our take

Are you gearing up for an exciting trip and considering an eSIM instead of a traditional local SIM card? eSIMs, like those offered by Holafly, allow you to activate data without the hassle of swapping physical SIMs. But how do they work in practice? You can install an eSIM before your travels, and it activates automatically upon arrival. Plus, it typically lets you keep your regular number while using data from the eSIM.

I’m traveling soon and keep seeing people recommend eSIMs instead of buying a local SIM card, especially services like Holafly.

I get the basic idea that it lets you activate data without swapping physical SIMs, but I’m still confused about how it works in real life. Do you install it before the trip and it just starts working when you land? And does it replace your normal number or can you still use your regular SIM at the same time?

For people who’ve used Holafly or similar services, was it actually worth it compared to getting a local SIM?
Any hidden downsides I should know before relying on it for a trip?

I’d love to hear what worked best for you while traveling.
