Which mobile networks does Czech Republic have?
All three networks passed 90 percent 5G population coverage by early 2025, with Vodafone at 96.47 percent, O2 at 93.56 percent and T-Mobile at 93.40 percent as of November 2024. 4G is effectively everywhere people live.
- T-Mobile: T-Mobile is the most awarded Czech network, taking 12 of 14 awards outright or jointly in Opensignal's February 2025 report, with 5G reaching over 93 percent of the population.
- O2: O2 finished its network modernisation with about 5,300 5G base stations covering 96 percent of the population and won Opensignal's 5G Coverage Experience award outright.
- Vodafone: Vodafone reported the highest 5G population coverage of the three at over 96 percent in late 2024 and is a joint Opensignal winner for availability and reliability.
The Czech Republic has an active MVNO market riding on the three host networks, but travel eSIMs and tourist SIMs all end up on O2, T-Mobile or Vodafone infrastructure anyway.

Is 5G available in Czech Republic?
5G is close to nationwide on all three carriers, and the operators signed a five year deal with the government to extend 5G into 600 underserved rural areas, so coverage keeps improving outside the cities.
How much data do you need in Czech Republic?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Czech Republic right now:
eSIM or a local SIM at the airport in Czech Republic?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Czech Republic starts at $2.87 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Czech Republic eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Czech Republic
Bring a passport when buying a local SIM. EU roam like at home applies, so anyone with an EU SIM can simply roam at domestic rates.
At Prague airport there is a Vodafone shop in Terminal 2 arrivals open 6am to 10pm, with tourist plans from about 800 CZK for 10GB over 30 days. City centre shops from all three operators are 10 to 20 percent cheaper, so many travellers wait.
Coverage is a non issue on the main tourist trail. If you are on an EU plan you likely do not need a local SIM at all for a short trip.

Do Czech Republic eSIMs support 5G?

Can I top up my Czech Republic eSIM if I run out?
Yes. 13 of the 13 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
