Hungary travel data eSIM
What is a Hungary eSIM?
Traveling to Hungary? A CometSIM eSIM lets you explore Budapest’s historic streets, the shores of Lake Balaton, and the country’s plains without hunting for a local SIM. Install the eSIM before you depart, keep your home number, and stay online as soon as you connect in Hungary, whether you’re navigating city transport or checking museum tickets.
In Hungary the eSIM links to Telenor Hungary 5G and Vodafone 5G networks. Your data allowance runs from the moment you first connect to either network, and you can use it for maps, translation, and booking apps throughout your stay.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operators does the Hungary eSIM use and what does that mean for a traveller?
The eSIM connects to Telenor Hungary 5G and Vodafone 5G. This gives you access to the services those operators provide, allowing you to use data for maps, apps, and online bookings while in Hungary.
Does the eSIM also work in a neighbouring country of Hungary?
No, this is a single‑country plan valid only in Hungary. CometSIM offers regional plans that cover multiple countries for travelers heading beyond Hungary’s borders.
Which plan size suits a trip to Budapest and Lake Balaton?
As a rough guide, the 5 GB 30‑day plan often fits a moderate amount of navigation, sightseeing, and booking app usage for a two‑city visit, while heavier users might consider the 10 GB option.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
