Your eSIM connects automatically to the Czech Republic's strongest mobile networks — O2, T-Mobile and Vodafone — for fast, reliable 4G/5G from the spires of Prague to the spa town of Karlovy Vary and the historic streets of Český Krumlov.

The Czech Republic's largest network with the widest 5G reach — your main connection across cities, towns and rural regions alike.

From wandering Prague's Old Town Square and crossing the Charles Bridge to soaking in the spa town of Karlovy Vary or exploring the fairytale castle of Český Krumlov, your unlimited data keeps maps, translation and ride-hailing apps running wherever the Czech Republic takes you.

Will my Czech Republic eSIM work beyond Prague in smaller towns?+

Yes. Your eSIM runs on the Czech Republic's leading carriers, which provide solid 4G/5G across Brno, Český Krumlov, Karlovy Vary and the smaller historic towns. Signal may thin out in the deep forests of Bohemia and Moravia or on remote hiking trails but reconnects automatically as you return to populated areas.

Can I share my Czech Republic eSIM as a hotspot?+

Absolutely. Tethering is fully supported, so you can share your unlimited connection with a laptop, tablet or a travel companion's phone — perfect for working from a Prague café or keeping the group online during a day trip to Český Krumlov.
