Zapp Mobile
Zapp Mobile was the first CDMA 450 MHz mobile phone operator in Romania, now part of Telekom Romania. Zapp has around 200,000 subscribers left, giving the CDMA network around 1% market share, and the number is declining because of migration of the customers to other GSM or UMTS networks. Zapp is currently aimed at business people and companies, especially due to its attractive billing plan, that allows easy creation of company networks through shared fees and special volume discounts, and because of fast and cheap mobile Internet access in the absence of wireless wi-fi public networks. The coverage and quality of signal has improved consistently in the past years, at present Zapp reaching over 90% of the urban population, but is still far behind that of the competitions, that cover between 95 and 97 of the total population of the country. In 2006 Zapp got a UMTS 2100 MHz license.
Zapp Mobile is a company of Telemobil S.A. România, which was a spin-off of Telefónica Romania, the first Romanian mobile service provider.
On 30 June 2009 Zapp Mobile was acquired by OTE and it is in the process of integration in OTE's Romanian mobile unit Cosmote Romania.
As of 24 March 2013 Zapp CDMA licence expired and the CDMA 450 network was closed down.
