Prague eSIM

100 Czech Republic plans · from $2.23

Prague's old town is a deliberate maze — the streets curve, the numbering is dual, and the same square has three names depending on which sign you read. A travel eSIM keeps live navigation running, and covers the awkward airport transfer, which is the one part of arriving in Prague that catches people out.

Landing at Václav Havel (PRG)

There is no train or metro directly to the airport. You take bus 119 to Nádraží Veleslavín and change to metro line A — roughly 40 minutes total. Having data on arrival makes that transfer far less stressful than working it out from the terminal signage.

Which networks you'll be on in Prague

Siima eSIMs for the Czech Republic ride T-Mobile CZ and O2. Both give full 5G across Prague; T-Mobile has slightly better coverage in the outer districts and along the D1 motorway.

Coverage around Prague

Metro lines A, B and C

Full coverage in stations and tunnels across all three lines. The deep escalators at Náměstí Míru — among the longest in Europe — keep signal the whole way down.

Old Town, Charles Bridge and Malá Strana

Good coverage throughout, though the density of stone and the crowds on Charles Bridge at sunset can slow throughput. Signal holds on the bridge itself.

Prague Castle and Petřín

The castle complex and the Petřín funicular are well covered, including the hill paths and the lookout tower.

Kutná Hora and Český Krumlov

The two standard day trips both hold 4G. The train to Kutná Hora is fine throughout; the longer bus run south to Český Krumlov dips briefly in the wooded stretches.

How much data you need

Prague is compact and mostly walkable: 2–3 GB covers a long weekend comfortably. A week with day trips is closer to 4 GB.

Frequently asked questions

Is a Czech eSIM valid for a day trip to Dresden or Vienna?
No — a Czech Republic plan stops at the border, and both are popular day trips from Prague. If you are crossing into Germany or Austria, a Europe regional plan covers all three countries on one eSIM.
Do I need to register my passport for a SIM in the Czech Republic?
Not for an eSIM. Some Czech prepaid SIMs require registration to stay active beyond an initial period; a Siima eSIM is issued before you travel and has no in-country registration step.
How do I set up an eSIM before arriving in Prague?
Install it at home while you still have Wi-Fi: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Leave the line switched off until you land — the plan starts counting from first use in Czech Republic, not from purchase.
How much data do I need for a trip to Prague?
Prague is compact and mostly walkable: 2–3 GB covers a long weekend comfortably. A week with day trips is closer to 4 GB.
Is an eSIM cheaper than roaming in Prague?
Almost always. Daily roaming passes from most home carriers run $10–15 per day, while Siima plans covering Prague start from $2.23 for the whole trip. You also avoid per-megabyte charges if you exceed a roaming pass allowance.
