O2 Czech Republic: A major integrated operator providing extensive mobile and fixed-line services, including 2G, 3G, 4G, and 5G networks.
T-Mobile Czech Republic: A subsidiary of Deutsche Telekom, offering comprehensive mobile services with widespread coverage across the country.
Vodafone Czech Republic: Part of the Vodafone Group, delivering a range of mobile services with a significant customer base and network reach.
In addition to these MNOs, the Czech Republic hosts several Mobile Virtual Network Operators (MVNOs) that provide mobile services by leasing access from the major carriers. Notable local MVNOs include SAZKAmobil and Lama mobile, both of which utilize Vodafone's network infrastructure. It's important to note that most travel eSIMs rely on MNO infrastructure rather than MVNOs.

All listed plans support inbound and outbound voice calls and SMS, though some only allow inbound SMS or combined inbound/outbound SMS.
