⚠️ Important: About "1 Day" Calculation Methods

eSIM providers use different "1 day" counting methods:

  • 24-hour basis: 24 hours from activation = 1 day
  • Calendar days: Local time 00:00-23:59 = 1 day
  • UTC basis: Day changes at UTC 00:00

📌 Please check each service's terms to understand their day counting method before purchase.

💡 Helpful Tips

  • 🔄 For connecting flights, calculate from your first arrival destination
  • ⏰ Consider time zone changes that might affect day calculations
  • 📞 Consider purchasing 1 extra day for emergency communication needs
