So I just received my Poco X3 NFC. Before I purchased it I made sure that it supported the 4G bands that Boost/Telstra uses for VoLTE. I went ahead and dialled ##86583## to enable VoLTE and also dialled ##869434## to enable VoWIFI. The VoLTE logo doesn't pop up at the top of my screen and when I go to make a call it changes over to 3G. I swapped sim card slots and restarted the phone, but it still doesn't work. If I pop my sim into my Galaxy S8 VoLTE works straight away.
Does anyone know how to get VoLTE to work?
Thanks.
I have the same case with my Mi5s.
I do not have all 4g bands but from what I read, Telstra provides VoLTE on 700 Mhz (B28).
Are the toggle available and switched on in the settings ?
VoLTE activated on your boost account ?
Can take up to 24h to work as per a Boost representative (not sure if this quite accurate tbh).
