Prepaid Data SIM Card Wiki

Basics[]

The Czech Republic has 3 GSM-based network operators:

  • T-Mobile (owned by Deutsche Telekom)
  • O2 (owned by PPF)
  • Vodafone (UK-owned)

A fourth operator Nordic telecom (formerly known as U:fon) is on GSM-incompatible CDMA 450-MHz reaching 90% of the Czech population with up to 3.1 Mbps speed. This band is not compatible with usual CDMA-phones either and only works with devices specifically designed for CDMA 450. They aim to start 4G/LTE on 450 MHz which is also incompatible with all usual GSM or CDMA devices. That's why they aren't mentioned any further.

Since a few years already more than 50 MVNOs have started up: COOP mobile, TESCO mobile, mobil.cz, OpenCall, Kaktus, Odorik.cz and SAZKA mobile are given as examples for good data rates, but there are still some more on the market.

2G/GSM covers all of the country on 900 and 1800 MHz like in the rest of Europe. 3G/UMTS is usually on 2100 MHz but it is available only in bigger cities. 4G/LTE is on 800 MHz, 1800 MHz, 2100 MHz and 2600 MHz (Bands 1, 3, 7, 20) available to all users and the coverage is much better than 3G. For 5G auctions will be held in 2020 and some operators have already started on n38 (3500 MHz) in city centers.

All three operators have 4G/LTE coverage 99% of population in 2018. O2 and T-Mobile also have network sharing agreements for 2G and 3G practically everywhere outside of Prague and Brno. That's why their footprint is almost the same outside these two towns.

SIM cards are available in the stores of the network operators and in many kiosks and supermarkets. Prepaid SIMs in the Czech Republic don't require any personal registration. Recharge vouchers can be bought at many kiosks, post offices and petrol stations.

Unlike in many other European countries, you will lose all credit on a Czech SIM card, if you don't top-up your balance periodically; periodic usage is not enough. This can be hard to do from abroad as some Czech operators may decline non-Czech credit/debit cards for online payment.

EU flag.png
The Czech Republic is part of the EU, where from June 2017 new international roaming rules are enforced. In most European countries you can now 'roam like at home' at domestic rates rather than excessive roaming rates. Two major Czech operators apply rules without restrictions, but Vodafone and some smaller providers have opted out. For specifics about the new regulation check European Union chapter and every provider below.

T-Mobile[]

Czech T-Mobile has good 2G and 3G coverage throughout the Czech Republic rivalling with O2 and Vodafone: coverage map. It's the market leader in the country with 40% share.

4G/LTE is also open for prepaid on 800, 1800, 2100 and 2600 MHz (Bands 1, 3, 7, 20) with almost the same coverage as O2 at 98% in 2020. 5G is open for prepaid.

Further fees[]

If you spent less then 100 Kč during the last 30 days on your SIM card line (not your account), you will be charged 0.70 Kč fee per day for your active SIM card. However, you may suspend/resume the SIM card online to avoid this fee. The balance, phone number or SIM card doesn't expire, so it can be good option if you visit Czech Rep. from time to time.

Two years after last recharge to your account, another fee will be imposed: 2 Kč per month are charged for inactive accounts.

EU roaming []

International roaming is blocked by default. You will need to sign this amendment to contract, where you undertake to pay in 30 days any debit that could occur on your account due to roaming services or premium SMS services. You can sign in their office (Prague or Brno) or verify your signature at any post office (fee: 30 Kč) and send it to them by post. Only then, roaming is opened and "roam like at home" rules apply.
