Singtel is debuting its new mobile data add-on, DataX3, at its exclusive iPhone 7 launch event at Marina Bay Sands Convention Centre tomorrow.
“DataX2 has been extremely well-received and is very popular with our customers, leading us to create an even more attractive offer of DataX3. Now, customers can choose to get more value for their money by simply adding on DataX2 or DataX3, depending on their data consumption needs,” said Yuen Kuan Moon, Chief Executive Officer, Consumer Singapore, Singtel.
Available to Singtel Combo Plan (Combo 2 and above) customers, DataX3 follows the launch of the DataX2 add-on that was first introduced earlier this year.
DataX3 offers significant cost savings to customers who need more data.
For example, a customer on a Combo 4 plan will have the option to top-up S$9.90 per month to increase the current 4GB entitlement to a total of 12GB of mobile data.
It is available to new and re-contracting customers on eligible Combo Plans with a minimum subscription period of 24 months.
WiFi Calling
Singtel also announced that it will offer WiFi Calling (also known as Voice over WiFi) to Singtel mobile postpaid customers from today.
This service allows customers to make HD quality voice calls and send SMS via any local WiFi connection without the use of an app.
The calls will switch seamlessly to the Singtel 4G network when users move out of WiFi hotspot coverage.
The service is available at no additional cost.
At launch, WiFi Calling will be available on select iPhone, Samsung Galaxy and Sony Xperia smartphone models, with other devices to be supported in the coming weeks.
* The currently supported phone models are: iPhone 7, iPhone 7 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, Samsung Galaxy S7 4G+, Samsung Galaxy S7 Edge 4G+ and Sony Xperia X.
To enjoy the service, customers will need to switch on the VoLTE, and WiFi Calling settings on their device and ensure that it is running the latest firmware or iOS.
However, you should note that voice calls and SMS messages made over WiFi will still utilise the talk time and SMS bundles of customers’ mobile plans.
