Money & Savings
Every traveler knows the scene — you land after a long flight, find the local SIM counter, wait in line, show your passport, fill a form, and finally get connected. That was the only way to get mobile data abroad in the past.
Today, with Roamvy eSIMs for travel, travelers can activate data in just seconds, often for a lower cost.
This guide compares airport SIM cards vs eSIMs across 10 popular international hubs to show which truly saves you time and money.

- Limited data validity (often 7–10 days)
- Long queues during busy travel hours
- Passport registration delays
- No easy way to top up or reuse
Average setup time: 20–40 minutes
Average cost: $15–$30 for 5GB

When Airport SIMs Still Make Sense
While eSIMs are the clear winner for most travelers, airport SIMs can be helpful if:
- Your phone doesn’t support eSIM technology.
- You need a local voice number for making calls/SMS messages.
- You’re traveling long-term in a single country.
For everyone else, Roamvy eSIM for travel is faster, cheaper, and far more flexible.

After long flights, every minute counts.
With Roamvy, you can land, turn off airplane mode, and get connected immediately — skipping queues, paperwork, and stress.
That’s why thousands of travelers switch from airport SIMs to Roamvy before every trip.
