eSIM vs roaming: which is cheaper abroad?
Roaming means using your home plan on a foreign network — simple, but usually billed per day, which adds up on longer trips. A travel eSIM lets you buy just the data you need, up front, at a fixed price.
When roaming is fine
For a quick one‑ or two‑day trip with light use, your carrier’s roaming pass can be convenient enough. The cost problem starts on multi‑day trips.
When an eSIM wins
On trips of several days, a travel eSIM is usually cheaper and more predictable: you see the price before you buy, pay once by card, and there is no bill shock when you get home.
FAQ
Can I use both?
Yes. Keep your home SIM for your number (roaming off) and use the eSIM for data.
