U Mobile WiFi calling service has been launched today, the first in Malaysia. With the new service, customers will be able to make and receive voice calls over a personal or public WiFi connection.

According to the Telco, One of the key challenges faced by Telco operators in Malaysia today is providing good in-building voice coverage especially for high-rise and offices. U Mobile WiFi Calling is the perfect solution to voice coverage issues as most buildings today have WiFi connectivity.
U Mobile WiFi Calling is available to both its prepaid and postpaid customers from today at no additional charge. With the new service, customers will be able to call and receive calls even in areas of limited network coverage such as basements, indoor or remote areas as long as they are connected to a WiFi terminal.
Unlike other Voice over Internet Protocol (VOIP) calls such as Skype, Viber and WhatsApp, WiFi Calling provides a similar experience to normal mobile phone calls as WiFi calls are made and received using existing mobile numbers. Apart from that, one may make WiFi calls to both mobile numbers as well as landlines. U Mobile customers may also make IDD calls with WiFi Calling.
For U Mobile customers who are travelling, WiFi Calling offers savings, as there will be no roaming charges for any calls made via a WiFi connection. This means, every time a U Mobile customer makes a WiFi call to a Malaysian number, regardless of where he or she is, the call will be treated like it was made from Malaysia.
