Singtel Launches DataX3 and WiFi Calling (video)

Good news for Singtel customers. Singtel has rolled out 2 new services that will increase your Data (with a small fee) and allows quality calls on your phones. Introducing the DataX3 and WiFi Calling from Singtel. Both services are available now.


I got to hear about DataX3 at the iPhone 7 launch on Friday. I believe this is good for those with high data consumption and yet do not want to increase their monthly subscription cost via Combo upgrade. Here is a table showing the DataX3 plans.

Combo Mobile Plans with DataX3


WiFi Calling

WiFi Calling is a free service from Singtel. With WiFi Calling, you can connect to the mobile network with just WiFi signal. I can imagine in a carpark with just WiFi signal and without Cellular network to benefit from it.

However, when you use WiFi Calling to make your call or SMSes, it will still utilize the talk time and SMS bundles of your mobile plans. In my opinion, you are helping Singtel off-load the congestion on the Cellular Network with WiFi.

Here is a short video on how it works.

Unfortunately, only a handful of devices support WiFi Calling at the moment. Read the Press Release for both news – DataX3 and WiFi Calling

Singapore, 16 September, 2016 – Singtel debuted its new mobile data add-on, DataX3, at its exclusive iPhone 7 launch event at Marina Bay Sands Convention Centre, today. With DataX3, customers will enjoy triple the mobile data allowance on their plans, for just S$9.90 a month.

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.

“We are always looking for innovative ways to give our customers more affordable data because mobile data has become essential to most Singaporeans for communicating, shopping, banking and entertainment. 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 Mr Yuen Kuan Moon, Chief Executive Officer, Consumer Singapore, Singtel.

DataX3 offers significant cost savings to customers. For example, a customer on a Combo 4 plan will have the option to top-up S$9.90 per month to get 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.

“WiFi Calling is a network innovation which offers added convenience and an enhanced mobile experience to customers. Our customers can now have mobile coverage even in difficult to reach places such as basements and windowless rooms, as long as there is a WiFi signal. This service extends our extensive mobile network to cover a wider footprint and complements our ongoing efforts in delivering the fastest and widest 4G service in Singapore,” said Mr Yuen.

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. Calls and SMS messages made over WiFi will utilise the talk time and SMS bundles of customers’ mobile plans.
