VoWiFi for Hotlink

EXPAND ALL COLLAPSE ALL

• What is Voice over WiFi?

  Voice over WiFi (VoWiFi) is a voice call service that uses Voice over IP (VoIP) technologies from mobile devices connected across a WiFi connection. You can use this service to make HD quality calls via any local WiFi connection without the use of an app.

• What is the benefit of VoWiFi?

  Voice over WiFi (VoWiFi) allows you to receive and make calls over a WiFi network on your Maxis mobile line when mobile signal is limited or absent. While you move between strong 4G coverage network and weak or no Wi-Fi signal, the call will continue without any interruption.

• How do I activate VoWiFi? Do I need to call Maxis to activate VoWiFi on my Maxis Mobile?

  Effective 16 December 2021, all Hotlink customers will be provisioned with VoWiFi service. Do check if your phone is compatible over Maxis VoWiFi.

• What are the disadvantages of VoWiFi?

  VoWiFi is dependent on WiFi networks and WiFi connections may lag with inadequate signal strength especially crowded venues, i.e. malls, hotels, airports, universities & cafe.

  As VoWiFi is an IP call, seamless handover to cellular calls at 2G coverage areas is not possible when users move to a weak WiFi signal corner with 2G coverage only.

  Apart from this, some devices do not support VoWiFi, hence users will need to have a compatible device before using this service.

• How to enable VoWiFi on my device?

  Different phones may have different steps to enable VoWiFi.

  In general:
  From your phone, click at SETTINGS > MOBILE NETWORK > Enable WiFi Calling/VoWiFi

  If your phone does not have this option, it may not support Maxis VoWiFi. Do ensure that your phone is updated with the latest software.
  

• Do I need to change the SIM card to use VoWiFi?

  LTE-SIM is required to enjoy VoWiFi, to check if you’re on LTE-SIM:

  Hotlink Unlimited, dial *100*6*1*4# 
  Hotlink Video or Pantas, dial *100*6*1*5# 
  Other plans, dial *100*6*1*6# 

• What is the charging rate for VoWiFi?

  Calls within Malaysia will be charged according to the standard call rates according to your rateplan.

  If your Mobile plan is bundled with voice minutes, VoWiFi calls will utilize those minutes. In the absence of bundled voice minutes, you will be charged at Pay-Per-Use rate.

• What are the differences between VoLTE and VoWiFi?

  VoLTE or Voice Over 4G LTE network offers superior voice quality as compared to VoWiFi. You can still browse while being on a call. It has multitasking capabilities to switch between apps, such as video calling, multimedia file sharing, images and phone calls simultaneously at the fastest speed.

  VoWiFi uses the WiFi network to make calls in HD. VoWiFi improves call reliability indoors, regardless of your mobile signal strength.
