Czech mobile start-up U:fon, the operating arm of local concern MobilKom, yesterday added mobile voice calls to its existing portfolio of data transmission and fixed-wireless call services, the Prague Daily Monitor reports. The operator became the fourth mobile operator in the Czech market when it launched commercial data-based services in May 2007. In a press release the newcomer said its CDMA network now covers 75% of the population, a figure it hopes to increase to 85% by the end of the year. Launching the new mobile voice service, U:fon said it had struck interconnection agreements with all three incumbent cellcos. It is offering a range of phones based on CDMA technology, and hopes to sign up 70,000 customers this year, rising to 300,000 after three years. According to TeleGeography’s GlobalComms database, MobilKom received its CDMA licence in 2005 and later signed a deal with Chinese equipment vendor ZTE to build out its nationwide CDMA network. U:fon was issued with a prefix code and mobile numbers by the Czech Telecoms Office (CTU) in late 2006 to offer services in the 410MHz-430MHz band.
