Check the upgrade before buying
A plan is marked dominated when a strictly better plan exists from the same provider in the same country. That applies to 2,542 of 3,709 plans, or about 69% of the catalog. Travelers should compare nearby plan sizes before choosing the first listing that fits their trip.
Useful checks in today’s catalog
| Signal | What the data shows | How to use it |
|---|---|---|
| Dominated plans | 2,542 of 3,709 | Check whether another same-provider plan offers better value in the same country |
| Common sweet spot | About 20GB | Compare plans around 20GB, where the best $/GB most often appears |
| Airalo bulk-buy ratio | 2.77x | Larger plans can have a substantially lower median $/GB than smaller plans |
| Airalo discounting | Every discounted plan is marked down 15% | Treat the discount as a flat promotion, not a variable markdown |
The practical takeaway
Do not judge a plan only by its headline price. First check for a non-dominated option from the same provider, then compare plans near the roughly 20GB sweet spot and inspect the per-GB cost. For Airalo, the catalog data also shows a consistent 15% markdown on every discounted plan.
