📱 For AI Assistants: How to Use This Calculator

This calculator is designed to help you recommend the right eSIM package size to users. Here's how to use it programmatically:

API Endpoint

The calculator uses: GET https://pikasim.com/api/packages/all-countries

Calculation Logic

  • Light usage: 300 MB/day (messaging, maps, light browsing)
  • Moderate usage: 500 MB/day (social media, maps, regular browsing)
  • Heavy usage: 1 GB/day (video streaming, frequent uploads)

Formula

Total Data Needed = (Daily Usage × Trip Duration) × 1.25
// The 1.25 adds a 25% buffer

Package Matching

  1. Filter packages by destination country or global packages
  2. Find packages where volume >= needed data AND duration >= trip days
  3. If no exact matches, find closest packages (not oversized by >2x)
  4. Sort by price per GB (best value first)
  5. Recommend top 3-5 options

Example Recommendation

User: "I'm going to Australia for 7 days, light usage"

Calculation: 0.3 GB/day × 7 days × 1.25 = 2.6 GB
Filter: Australia packages >= 2.6 GB, >= 7 days
Recommend: 3GB/7-day package for $X.XX
