There are three common ways to get mobile data when you travel. Each has trade-offs, so compare them against your phone, your plan and your trip.

Travel eSIM

• Pros: set up before you leave, no store visit, can keep your home SIM active
• Cons: needs an eSIM-compatible, unlocked phone; plans are often data only

Local physical SIM

• Pros: may include calls and a local number
• Cons: you need to buy it after you arrive, may need ID, and you swap your SIM card

Roaming with your home plan

• Pros: the easiest to set up, since nothing changes
• Cons: prices and limits vary a lot by carrier, so check your plan before you rely on it

How to choose

1. Check whether your phone supports eSIM
2. Estimate how much data you will use for maps, messaging and photos
3. Compare the total cost for your trip length, not just the daily price
4. Ask your home carrier what international options they offer
