1. For short trips, start with eSIM
For a one-to-seven-day stay and a compatible phone, installing an eSIM before departure is usually the quickest option. Enable its data line after arrival.
Keep the original SIM for messages and turn off data roaming on that line.
2. Compare roaming when your number matters
Carrier roaming can be simpler when you must answer calls on your usual number or claim expenses through work. Check coverage, throttling and hotspot rules.
3. Consider a local SIM for longer stays
For several weeks or more, a local prepaid SIM may cost less. Compare identity checks, top-up methods and number expiry.
4. Final checks
Confirm the phone is unlocked and supports local bands. Plans change quickly, so verify price and terms on the provider's official page before purchase.
