rahuldixit2010 13 Report post Posted October 2, 2016 The VoLTE is enabled but it is not working. VoLTE sign doesn't come. Data is working fine. Does VoLTE work on it. Did you purchased new sim or old jio sim which got activated in other phones. Share this post Link to post Share on other sites

Did you enable "use VoLTE when available" from Dialler ->> More ->> Settings ->> VoLTE If so, then the phone is not fully unlocked and IMS is locked with the original carrier and will not get registered with any other Network.

rahuldixit2010 13 Report post Posted October 4, 2016 yes, it enabled from settings. AT&T it is under Data Setting in the name "Enhanced LTE Services". The phone is full unlocked, but then also it is not working. Share this post Link to post Share on other sites
::: VA ::: 531 Report post Posted October 6, 2016 Guys sorry to say but you are all going about it slightly off direction. Having all supported lte bands unlocked and volte feature enabled in your phone is simply not enough.VOLTE works only and only on devices that the carrier explicitly supports. Your imported handsets are unlocked but model numbers would never match on your Indian carrier. You can benefit from LTE data and jio4gvoice app.Sent from my MI 5 using Tapatalk 1 Share this post Link to post Share on other sites

gpkumaran 21 Report post Posted October 10, 2016 thats what helped me in my s6 edge bought from singapore. eventhough bth here and Sg the model is g925i. i had to flash INU csc version to get volte. even after flashing that, i had to do a factory reset in stock recovery so that the CSC changes to INU. P.S: it usually shows csc in the bottom above the single-sku. btw check your cscversion.txt and softwareversion.xml in system folder if it corresponds to your model number.
