|---|---|---|
| Price (7 days, 5 GB) | $1.14 | $8 avg |
| Where to buy | Online, before you leave | Airport, store, or online |
| Activation time | Under 2 minutes | 5 – 60 minutes |
| Passport required | No | No |
| Phone number included | Data only | Yes, local number |
| Hotspot tethering | Yes (HelloRoam, Saily) | Yes (most plans) |
| Works on dual SIM | Yes, alongside home SIM | Replaces your home SIM |

How to set up an eSIM in Czech Republic
eSIM activation works the same way across all carriers. The process takes under 5 minutes on a compatible phone.
Confirm eSIM compatibility
Your phone must support eSIM. Most phones released after 2020 do, including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Check Settings for an eSIM or digital SIM option.
Check your phone is carrier-unlocked
Some carriers lock phones to their network. If you bought your phone on contract or from a carrier store, contact them to unlock it before your trip. eSIMs from third-party providers will not work on a locked device.
Purchase your Czech Republic eSIM plan 1-30 days before your trip
Buy from HelloRoam, Airalo, Holafly, or another provider listed above. You can purchase 1 to 30 days before departure. Choose a plan that covers your intended stay. You receive a QR code by email within minutes of purchase.
Scan the QR code
Go to Settings > Mobile / Cellular > Add eSIM (or Add Data Plan). Point your camera at the QR code. The eSIM profile installs in about 60 seconds.
Activate on arrival in Czech Republic
Most plans activate when you land. Set the eSIM as your primary data line in Settings. Turn off data roaming on your home SIM to avoid unexpected charges. Run a speed test to confirm you are connected.
eSIM notes for Czech Republic
Czech Republic has three carriers: T-Mobile CZ (dominant, best 5G), Vodafone CZ, and O2 Czech Republic. EU roaming applies. 5G is deployed in Prague and other major cities. CZK is the currency, not EUR.
Prague 5G from T-Mobile covers the city center, Vinohrady, Smichov, and Holesovice. The Old Town, Charles Bridge area, and Mala Strana all have 4G from all carriers. The Prague Metro has T-Mobile 4G inside tunnels on most lines. On the Prague to Brno high-speed route, T-Mobile maintains consistent 4G with brief gaps. The Bohemian Switzerland national park near Decin has O2 4G on main trails and viewing areas. Cesky Krumlov town center has T-Mobile and Vodafone 4G. The Sumava national park forest area is patchy from all carriers. Moravia wine country around Mikulov has good T-Mobile coverage.
