Airport SIM kiosk vs eSIM online: the real math
The airport SIM kiosk lives off one customer: the traveler who landed disconnected with no alternative. That urgency gets billed. The real math of both paths.
Why the kiosk is expensive
- Captive customer: you just landed, you need internet NOW for transport and to say you arrived. You are not going to compare prices.
- Premium rent: arrivals-hall square meters are among the most expensive on Earth, and your SIM pays for them.
- "Tourist" packages: inflated versions of the normal prepaid plans, with fewer GB for more money than the same carrier downtown.
The comparison
| eSIM online (before you fly) | Airport kiosk |
|---|
| Price | Normal rate, with promos: from USD 1.79/day unlimited | Tourist rate: typically 1.5-3x the street price |
| Time | 0 minutes on arrival: you connect on landing | 15-60 min queue at peak times + passport paperwork |
| Hours | Buy 24/7, arrives by email in minutes | Many counters close at night: late flight = no SIM |
| Comparing options | Calmly, from your couch | Whatever is there, at whatever price |
When the kiosk is justified
Only two cases: your phone has no eSIM (older device) or you arrived with nothing sorted and need it now. Even in the second case there is a better way out: on the airport Wi-Fi you can buy the eSIM online in 5 minutes — often while everyone else is still in the kiosk queue.

How much more expensive are airport SIMs?
Typically 1.5 to 3 times the street price of the same carrier, with "tourist" packages carrying fewer GB. The newcomer's urgency gets billed.
Can I buy an eSIM while already at the airport?
Yes: on the airport Wi-Fi, the online purchase and email delivery take minutes — usually less than the kiosk queue.
What if my phone has no eSIM?
Then the kiosk or a carrier store in the city (cheaper) is the way. Check first: almost every phone since 2019 already has eSIM.
