An Essential Pre-Purchase Checklist

  • Understand your data needs: Think about how you use data and how much. Are you constantly browsing or using data-intensive apps like YouTube, TikTok, or games? Opt for a plan with a generous data allowance then. In case you’re a lighter data user can confidently choose a smaller plan.
  • Monitor your data usage: Before buying, keep track of your regular data usage. Here’s a brief breakdown to estimate how much data you’ll likely consume. Once your eSIM is activated, monitor your usage to avoid exceeding your plan limit. Consider turning off data roaming or using Wi-Fi hotspots when possible to avoid surprise charges.
  • Price and Data: find the sweet spot: Small data packages might seem cheap at first glance, but frequent top-ups can turn out to be expensive. Unlimited plans offer peace of mind but cost more. The key is finding the balance between price and your data usage habits.
  • Explore all of the available options: Before you embark on your Japanese adventure, take some time to research eSIM providers. Consider factors like data allowance, network speed, and coverage in your visiting regions. Choosing the right plan ensures you have a reliable connection throughout your trip.
