The short version
An eSIM (embedded SIM) is a chip already inside your phone that can be programmed with a mobile plan over the internet. Instead of buying a physical SIM card and slotting it in, you download your plan digitally. For travel that means you can be connected the second you land — no shop, no queue, no swapping cards.
How an eSIM works in 3 steps
Pick your destination and how many days you need. Flylo plans are unlimited data, so there's no counting megabytes.
No app required. Your eSIM installs straight from the Flylo checkout — scan a QR code or tap to add it.
Your eSIM activates automatically when you arrive and connect to a local network. Your home number stays live on your physical SIM.
eSIM vs physical SIM
Set everything up at home. No hunting for a SIM kiosk in an unfamiliar airport.
Your normal SIM stays active for calls and texts. The eSIM just handles data.
No tiny plastic card to misplace or damage. It's all digital.
Store multiple eSIMs and change destinations in a couple of taps.

What does eSIM stand for?
eSIM stands for 'embedded SIM'. It's a small chip built into your phone that does the same job as a physical SIM card, but it's programmed digitally — so you can download a mobile plan instead of inserting a plastic card.
Is an eSIM better than a physical SIM for travel?
For travel, yes. You can buy and install an eSIM before you leave home, keep your normal number active on your physical SIM, and switch between them in settings. No airport queues, no swapping tiny cards, no risk of losing your home SIM.
Will an eSIM work in my country?
Flylo eSIMs work in 190+ countries on the strongest local networks. Pick your destination, choose a plan, and you're connected the moment you land.
Does using an eSIM cost extra?
No. You only pay for the data plan you choose. There's no activation fee and no hidden roaming charges — the price you see is the price you pay.
Can I have more than one eSIM on my phone?
Yes. Modern phones store multiple eSIMs and let you keep several installed at once, switching the active one in settings. Most let you run one eSIM plus your physical SIM at the same time (dual SIM).
