FREQUENTLY ASKED QUESTIONS

VoWiFi/WiFi Calling, or Voice over WiFi, signifies an expanded aspect of VoLTE, permitting users to conduct voice and video conversations, or transmit text messages via a WiFi network, using their mobile phone’s built-in dialing system. The added value becomes particularly prominent when in locations with weak or nonexistent cellular coverage, such as within structures, indoors, or below ground level. In these instances, a strong WiFi connection replaces the need for a cellular signal, enabling regular call, message, and additional service capabilities. To avail this feature, you require a smartphone equipped with both VoLTE and VoWiFi functionalities.

The inclusion of VoWiFi/WiFi Calling within your VoLTE enabled handset isn’t necessarily guaranteed. It should appear within your device settings and can be activated via a simple toggle. Successful trials of WiFi Calling have been conducted on Samsung, OPPO, VIVO, and Digit devices.

Absolutely, with the proviso that the mobile device possesses the necessary technical specifications and maintains an active, valid WiFi connection.

There is no additional levy for utilizing VoWiFi features from Jazz. Bundle-subscribed customers will use resources already allocated to them. Non-bundle users will face charges calculated based on usage duration, at the standard base rate.

To utilize VoWiFi/WiFi Calling, subscribers must possess:

  • A VoLTE enabled handset with VoWiFi feature activated in the phone settings.
  • A 4G/LTE SIM.
  • Adequate balance (airtime) or an active voice & SMS bundle subscription.

To activate this feature, ensure your handset firmware is up-to-date, the VoLTE and VoWiFi/WiFi Calling functionalities are available and activated in your phone’s connection settings, and VoWiFi/WiFi Calling is enabled within the handset’s SIM settings. The procedure using a Samsung device as an example is as follows:

  • Open the phone application.
  • Click on the More options (three vertical dots) icon.
  • Navigate to the Settings menu.
  • Switch ON the Wi-Fi Calling feature once provisioned from the network side.

VoWiFi/WiFi Calling is accessible across Pakistan.

The requirement for VoWiFi is an active Jazz subscription and a viable WiFi connection.

The presence of a VoWiFi symbol adjacent to your WiFi signal bar signifies a successful connection.

You can either disable WiFi-calling within your device settings or disconnect from your WiFi network.

Yes.

The selected “Wi-Fi preferred” option in your Wi-Fi Calling settings allows your device to prioritize Wi-Fi connections for call and SMS transactions.

Ensure your WiFi connection’s signal strength is robust and functioning. Also, verify your balance or active voice/SMS bundle resources.

Yes. However, if VoLTE is deactivated, a disrupted Wi-Fi connection will terminate an ongoing call. For uninterrupted call experiences, enable both Wi-Fi Calling and VoLTE services.

VoWiFi features are incorporated in your device’s standard software updates. No ‘special’ update for VoWiFi exists.

Potential solutions include:

  • Verifying if your device supports VoWiFi/WiFi Calling and if the WiFi calling option is visible.
  • Ensuring your device’s software is updated.
  • Confirming your device’s WiFi connection is functioning.
  • Switching to another WiFi connection.
  • Checking if VoWiFi/WiFi Calling is activated in the device settings.
  • Checking if WiFi is prioritized over the mobile network for voice calls in the device settings.
  • Restarting your device.

No, VoWiFi will not be accessible to customers on international roaming. All VoWiFi calls are routed locally and will remain within Pakistan.
