lumia 640 xl LTE activate volte for reliance jio
Sir, I heard lumia 640 xl LTE, will support volte, in your site telling it must be activated from service provider,
In India reliance jio , is telling lumia 640xl LTE, has some OS problem, so it must be activated from Microsoft side,
As you are a Microsoft big windows OS , you must show interest in your product lumia 640 xl LTE to activate volte, and talk to reliance jio Telecom company To promote lumia 640xl mobile to get 3 months preview offers,
You can not seat quite, around 16 mobile company tied up with reliance jio, you must show interest, not reliance will show,
As we feel Microsoft company is wast ,

2017-04-17T13:45:06+00:00 It is up to Jio to support VoLTE on Windows phones. This has been said over and over.
T-Mobile in the Czech Republic supports VoLTE on Windows phones with their app and SIM with no update from Microsoft required.
Link to their VoLTE information. I can not provide a translated page because it is secure https.
https://www.t-mobile.cz/volte They support the Microsoft Lumia 550, 640 LTE, 650, 950, 950 XL directly, no firmware update required, just their app.
Your problem is with Jio, not Microsoft as seen with this example below.
Link in this forum from a user that used T-Mobile in Czech Republic SIM and was mad about the app that was installed and changed his phone when he installed their SIM. He did not understand he was getting VoLTE.
