The Czech incumbent is likely to change its name from Telefónica to M Telecom.
However, reports E15, it still plans to retain the brand O2.
The telco saw a change of ownership in November last year, when Telefónica agreed to sell a 65.9% stake in its Czech subsidiary to PPF Group for €2,467 million in cash.
Earlier this month it announced plans to reduce the number of divisions from nine to seven as part of a restructuring process.
