Czech Republic

Basics
The Czech Republic has 3 GSM-based network operators: A fourth operator 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.
 * T-Mobile (owned by Deutsche Telekom)
 * O2 (owned by PPF)
 * Vodafone (UK-owned)

Since a few years already more than 50 MVNOs have started up: COOP mobile, TESCO mobile, mobil.cz, OpenCall, Kaktus, Odorik.cz, SAZKA mobile and Vectone mobile are given as examples for good data rates, but there are still 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 on 2100 MHz in most of the areas. 4G/LTE is on 800 MHz, 1800 MHz, 2100 MHz and 2600 MHz available to all users. The former LTE coverage on 900 MHz of Vodafone has migrated to 800 MHz now.

Vodafone has the best 4G/LTE coverage in 2017: 99% of population get Vodafone's LTE while O2 and T-Mobile build up their LTE together and reach 93%. 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 out of these two towns.

SIM cards are available in the stores of the network operators or in many supermarkets without 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 many Czech operators decline non-Czech credit/debit cards for online payment.

A very effective way to use up surplus credit on a Czech SIM card is to spend it on premium SMS for tickets on public transport in Prague. Tickets purchased this way cost the network's standard SMS charge plus the price of the ticket. 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
