Compare the real trade-offs
A travel eSIM is quick to install and often data-only. Roaming keeps your number familiar but can cost more. A local SIM may offer a local number, but requires a purchase, identity process or store visit.
The cheapest headline price is not the only variable: include activation effort, app access, hotspot rules and what happens when something fails.
Match the option to your trip
There is no universal winner; the right choice is the one whose constraints fit your trip.
- Choose an eSIM when you want data ready before landing.
- Choose roaming when your number and carrier support matter most.
- Choose a local SIM when a local number or local service relationship is essential.
- Keep a second payment, map or data fallback for the first hour.
