Optus claims it is the first mobile carrier network operator in Australia to give postpaid service providers access to Voice over LTE (VoLTE) and Wi-Fi Calling.
VoLTE allows users to make and receive calls over the 4G network, and previously, only data services were offered via 4G to Optus MVNO postpaid customers.
Ben White, managing director, Wholesale, Satellite and Strategy, said the services would provide “new value and an improved experience for MVNO customers”.
“We’re excited to be the first mobile network operator to offer our MVNO partners the benefits of VoLTE, which is available everywhere the Optus 4G network reaches. We understand that high-quality connectivity and value is critical to our partners, which is why we’re committed to continuously improve our products and services.”
White explained that VoLTE works by utilising 4G technology to make calls, “as opposed to dropping down to 3G when a call connection takes place”.
White said that Optus’ wholesale partners are now able to benefit from voice over Wi-Fi – or Wi-Fi Calling – “which allows users with a compatible device to make and receive calls or text where there is limited mobile coverage but an accessible Wi-Fi service, such as home, office or public Wi-Fi”.
“Wi-Fi Calling is automatically provisioned with VoLTE and makes staying connected easier when mobile signal is limited and there is an available Wi-Fi service. It is particularly useful indoors and solves the problem of coverage holes in areas where mobile signals can struggle to penetrate,” White said.
“When Wi-Fi Calling is switched on and if there is insufficient mobile coverage, a device automatically detects and switches to an authorised WiFi connection to use voice and messaging services.
“When using Wi-Fi Calling or VoLTE, no additional charges will be made on top of regular voice call rates and customers’ mobile data will not be consumed.”
