Slashtel Hungary eSIMs start at $1.99 for 1GB over 7 days, across 7 plans. The lowest price per GB is $0.91 on the 20GB plan. A one-week trip costs from $1.99 (1GB). It connects to Vodafone, Telenor Hungary and T-Mobile on up to 5G. It is data only: your own number stays active for calls, SMS and bank codes. The QR code arrives by email within minutes; install it on Wi-Fi before you fly and the days start when it first connects in Hungary. Prices checked 20 October 2026.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Hungary is $5.89 on Vodafone, Telenor Hungary and T-Mobile. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
