VoWiFi is a technology that enables users to make/receive calls over Wi-Fi without the need to connect to a mobile network. Calls are made using the standard dialer, without the use of an additional application. Mobile phones may switch to VoLTE (4G Voice) when Wi-Fi signals are weak, without interrupting the call. Likewise, a call on VoLTE can switch to Wi-Fi when connectivity is available, without interrupting the call.


To activate, follow the below mentioned steps:
  • Ensure you have a VoWiFi supported device
  • Make sure the VoWiFi calling function is set to ‘Active’ on the handset settings
  • Request to activate the service by dialing #107#

What is the eligibility criteria to be able to activate VoWiFi?

You are required to have a device that has the VoWiFi feature enabled for the Dialog network, and a 4G SIM on your device

What are the device models that are compatible with VoWiFi on the Dialog network?

As of 16th October 2018, the following device models are compatible:

  • Huawei NOVA 3i
  • Huawei NOVA 3
  • Huawei P20 Pro
  • Huawei P20 Lite
  • Huawei P20

All future high-end Huawei phones released after this date will also contain the feature. Please refer to this page for an updated list of compatible devices.

What are the benefits of VoWiFi?

  • Ability to make calls over any Wi-Fi network
  • Superior call quality
  • Standard call charges only
  • Make any normal voice call via Wi-Fi without any app

What is the voice quality when using VoWiFi?

High quality voice and video calls can be made using VoWiFi. Voice quality on any Wi-Fi connection that has a data rate above 200kbps is as good as using the 4G voice (VoLTE) function. However, the quality may degrade should the speed of the connection drop below 128kbps.

How are calls charged?

Standard call tariffs for voice and video calling +tax will apply

Why is there a beta launch period?

During this period, customers have to request for the service to be activated via the #107# USSD. The service will then be activated for those who meet the eligibility criteria. Since the service involves using a public Wi-Fi connection, this period will be used to gather customer experience data prior to making it available for all customers by default.

Note: After activating the service, if the line gets disconnected temporarily and then reconnects, the VoWiFi service will not be reactivated by default. The customer is required to request activation again. This is only necessary during the beta launch period.
