4G mobile operator Tele2 Netherlands has launched VoWiFi (a.k.a. Wi-Fi calling), it announced on its website, noting that the solution solves the problem of poor signal in deep indoor locations and/or blocking by thick concrete walls in offices or homes.
VoWiFi calls for Tele2 subscribers do not attract any data usage charges, and the service is now available for consumers and business customers with compatible devices, activated via a downloadable app.
