Nokia Networks has announced that it is working with Polish mobile operator Polkomtel, which offers services under the Plus brand, to carry out the country’s first public trial of voice-over-Wi-Fi (VoWiFi) technology. The vendor says the new service lets users make regular calls when connected by Wi-Fi in locations with poor mobile coverage. During the trial period, the Wi-Fi Calling+ service is available to Plus users at Wi-Fi hotspots in Poland and across the EU. Justyna Kulka, Director of the Offer Management Department at Polkomtel, commented: ‘Thanks to the engagement of Plus users in the testing phase, we expect the final product to fully meet their needs and expectations. Our next goal is to integrate VoWiFi and VoLTE as an ultimate solution for voice services.’ Polkomtel is the third largest cellular operator in Poland behind T-Mobile and Orange, and is part of the Cyfrowy Polsat Group.
