lumia 640 xl LTE activate volte for reliance jio

When I fed ##7820# it shows sim unlock symbol and bar with no code please replay what to do

Sir, only one thing we must do, Microsoft site said Lumia 640 xl LTE has volte hardware and it will work volte, know all Lumia customer must go to consumer protection forum, that as we brought Microsoft Lumia mobile as site said it will work volte, we inserted jio SIM VOLTE is not working,then Microsoft  cheated all, we want full money back,

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 ,

Hi , 

in future we remember Microsoft as a cheater company who destroyed Nokia and Lumia phones and cheated worldwide lumia users.

when open market phones do not support volte, microsoft should not advertise it as volte phone in the open markets. first you check your website for specifications and reply. when they cant provide the service they should not say they have it. VOLTE dont require operator specific implementation for open market phones . VOLTE implementation can be done from changes in microsoft firmware, which microsoft is not doing. you people think the public are dumb and post some random replies to divert the issue.

as one of the member responded the following has to be done by microsoft for open market phones.

hello noobs ,don't say anything without knowing, ##7820#  is to unlock carrier to work with other sim ,for indian devices its unlocked,these 20 codes doesn't related to any Volte.if we can provision with volte ppkg ,settings will appear,if jio assist with windows phone we can tell any variables to access volte

Jio and Microsoft have to collaborate first. Then Jio will provide the unlock 🔓 code according to phone 📱 IMEI.
