eSIM or a local SIM at the airport in Slovakia?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Slovakia starts at $2.87 on this page, which is hard for airport kiosks to beat.

Do Slovakia eSIMs support 5G?
13 of the 13 plans we track for Slovakia include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I top up my Slovakia eSIM if I run out?
Yes. 13 of the 13 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
