All options for data abroad: roaming, eSIM, local USIM, pocket WiFi.
TL;DR
- Roaming: Use home carrier abroad—easy, expensive.
- eSIM: Buy data plan online, install before departure—good balance of cost and convenience; keep home number (dual SIM).
- Local USIM: Buy at destination—often cheapest for heavy/long use; may need to remove home SIM.
- Pocket WiFi: Rent one device, share—good for groups; pickup/return, battery, single point of failure.
