5. Does VoLTE consume data?

6. How do I know If I’m using VoLTE?
— For iOS users, the icon at the top left of your screen will remain as ‘4G’ when you are making or receiving calls.
— For Android users, you will see a VoLTE icon at the top right of your screen during calls.
7. Does VoLTE work for both outgoing and incoming calls if only one person has VoLTE?
Yes. As long as your mobile device supports VoLTE and you’re in a 4G coverage area, you can enjoy VoLTE-quality calls whether you’re making or receiving them — even if the other person doesn’t have VoLTE.
8. Can I use VoLTE while roaming?
Yes, you can use VoLTE while roaming, as long as there is LTE or 4G coverage. However, prevailing roaming call rates will apply.
9. Do VoLTE calls work when my mobile data is turned off?
Yes, you can still make and receive local VoLTE calls even if your mobile data is turned off. However, if you’re roaming, you may need to turn on mobile data or data roaming to use VoLTE.
10. What happens when I'm moving from 4G to 3G during a call?
If you’re on a VoLTE call and move out of 4G coverage, your call will seamlessly switch to the 3G network, so you can continue the conversation without interruption—though the call quality may be slightly reduced.
11. What should I do if I’m unable to make outgoing calls or use shortcodes after activating VoLTE on my phone?
If you encounter issues with outgoing calls or using USSD shortcode (e.g. *400#, *100#) after enabling VoLTE on your device, try the following:
a. For outgoing call issues: Disable VoLTE in your device settings or switch your network mode to 3G.
b. For USSD shortcode issues: Use the MyDST app or message WhatsApp DEE at +673 861 6888 to perform your transactions more conveniently.
