VoLTE Operators list

Hi Experts,
Anyone working with Telstra Australia?
Need to know there network is VoLTE enabled or not.
PLMN 505 -11

In GSMA document or website, you can find list of VOLTE Operators in each continent.

In GSA, it has database about operators.

Yes, it have. But unfortunately not all can afford paying their fees.

@ankgitm , you can try free Wikipedia:

Unfortunately, not for VoLTE specifically… If someone has a free source/link, please share it. (Alternative to GSA paid database)
