Use eSIM for speed and redundancy
An eSIM is useful when you want data immediately after landing or you want to keep your existing physical SIM active.
The tradeoff is often price and local features. Travel eSIM packages may cost more per gigabyte and may not include a local phone number.
Local SIMs make more sense for longer stays
If you will stay for weeks or months and use a lot of data, a local prepaid or monthly plan can offer better value.
Before buying, check identification requirements, activation steps, coverage and whether the plan renews automatically.
The best setup can be both
Many phones support more than one SIM profile. A practical setup is to keep your home number for authentication and use a local or travel data plan for everyday internet.
Confirm roaming settings so an accidental connection to the wrong network does not create a surprise bill.
