eSIM vs roaming vs local SIM card
There are three common ways to get mobile data abroad. Here’s how they compare.
| Travel eSIM | Roaming | Local SIM card | |
|---|---|---|---|
| Setup | Scan a QR code before you fly | None | Visit a shop or airport counter, often with ID |
| Cost | Prepaid: you pay a fixed price upfront | Set by your home carrier, and can be high | Local prices |
| Home number | Stays active in your phone | Stays active | Removed while the local SIM is in |
| Several countries | One regional plan can cover many countries | Depends on your carrier | Usually a new SIM per country |
| Calls & SMS | Usually data only (use WhatsApp or FaceTime) | Included, at roaming rates | Local number included |
When a travel eSIM is the best choice
- You want data as soon as you land, without hunting for a SIM shop.
- You want to keep your home SIM in your phone for bank SMS codes and calls.
- You’re visiting several countries and want one plan.
- You want to know exactly what you’ll pay before you go.
When something else may suit you better
- Your phone doesn’t support eSIM or is locked to your carrier.
- You need a local phone number for calls.
- Your carrier’s roaming package already covers your trip at a price you’re happy with. Check their rates before you go.
