A useful eSIM comparison starts with your destination, trip length and data needs. Work through the questions below, then compare plans that meet those requirements.
Choose how much data to buy
Start with your own mobile-data usage and adjust for the Wi-Fi you expect to have. Estimate an eSIM data allowance for your trip, including a worked calculation and questions to ask about unlimited plans.
Understand the price comparison
A cheap entry plan may last only a day or include little data. Our comparison methodology explains total price, price per GB, unlimited-plan limits, snapshot dates and affiliate links.
Check your phone and set up your eSIM
Compatibility depends on the exact phone model, purchase region and carrier lock. Read the travel eSIM setup checklist before buying and keep your provider’s installation instructions available.
