Yes Sameer you are right. It is Vodafone's issue that it is not able to provide VoLTE on Nokia 7 plus. I am chasing Vodafone since last 26 days and still they are not able to enable VoLTE on this device. I will update in this forum once they come up with some solution.
In my case Vodafone VoLTE was not working even before software upgrade.
Hi Sameer they are making you fool like they are doing with me since last 21 days. Ask them if Nokia 7 plus doesn't support VoLTE, why it is mentioned on your website. Also mail attached picture to them on these mail ID email@example.com, firstname.lastname@example.org, email@example.com.
Also tweet to Vodafone IN and DOT mentioning the whole issue.
Hi Ajit Bagal, Nokia 7 plus supports VoLTE out of the box. I tested it with Jio, Airtel and Idea sim cards.
Vodafone needs to add configuration(Some binary files) of Nokia 7 plus at their end.
