  • Video: Low = 500 MB/hr, Standard = 1,000 MB/hr, High = 3,000 MB/hr.
  • Social: 300 MB/hr; Maps: 8 MB/hr; Web: 80 MB/hr.

  • Recommendation logic:
    • Daily = smallest cap ≥ per‑day total; **duration** = smallest allowed duration ≥ trip days.
    • Package = smallest cap ≥ trip total AND validity ≥ trip days (for 3GB, prefers 15 days over 30 if both fit).
