3 Denmark has launched Voice over LTE and extended its Voice over Wi-Fi service to a range of new devices.
The company’s private and business customers on its Free Voice subscriptions and compatible handsets will automatically get access to VoLTE for free.
The service will initially be available to customers with iPhone 6 and iPhone 7 devices or with a Sony XZ or X Compact. The service will be introduced automatically for customers with the latest version of iOS.
3 also introduced VoWi-Fi to a range of new Android devices, including the Sony Xperia XZ, Sony Xperia X Compact, Samsung Galaxy S6 Flat, Samsung Galaxy S6 Edge, Samsung Galaxy S7 Flat, Samsung Galaxy S7 Edge, Samsung A3 (2017), Samsung A5 (2017).
The company first introduced VoWi-Fi March 2016.
According to 3 Denmark’s Network Director, Kim Christensen, the biggest advantage from VoLTE will be the automatic handover from Wi-Fi to 4G when available.
Christensen predicted all of its calls would ultimately be placed over the 4G network. She added: “When we launched Wi-Fi calls in March 2016 as the first telco in Denmark, we solved the problem for those customers who are in buildings where cell signal is weak. With Voice over 4G it’s possible for customers to continue a conversation even though they leave their house and Wi-Fi signal.”
She said other advantages would include better sound quality and the ability to use 4G data while making a call.
Telenor is the only rival Danish operator that has launched VoWi-Fi and VoLTE services.
Elsewhere in Europe, UK mobile operator O2 also launched VoLTE and VoWi-Fi this week.
