Most Xiaomi smartphones are comes with VoLTE enabled, but some old devices like Xiaomi Mi4i, does not have this feature or disabled it. Thus, you cannot use services like Reliance Jio on these devices. However, there is a workaround to enable VoLTE (voice over LTE) on Xiaomi Mi4i, if your device is rooted and running on MIUI 7 or MIUI 8 ROM. Check out the guide below to know how to enable VoLTE on Xiaomi Mi4i to use Jio voice call over LTE.

In this tutorial, we will let you know the procedure for enabling VoLTE on Xiaomi Mi4i, so that you can use 4G services like Reliance Jio on it. Note that although Xiaomi Mi4i supports Reliance Jio’s 4G network (LTE), it will not support VoLTE, so you cannot make phone calls over LTE. This workaround enables VoLTE on Mi4i, which requires editing a system file.


As this workaround requires editing a system file, make sure that your device has full root access. You can check it by using app like Root checker. To edit the system file, you need to install ‘SQLite Editor’ app (it is a paid app) from Play store. With this app user can browse, open and edit SQLite files on their phone.

Warning: Before head over to the guide note that it requires editing some system file, which is a risky job and should not try, if you are an inexperienced user.

  1. I also own Mi4i and just to enable it, I rooted my phone and purchased SQLite Editor, which costs Rs. 179.39/- and its not free. But there is no such option named volte_feature_disabled, I wasted money in this editor and an entire day.

  2. Volte doesnot require any hardware is a software dependent mi4i is a 4g handset,it should support volte,all it need is a software update from the manufacturer side.i own a zenfone laser which was launched even before jio.initially it didn’t supported volte.after jio was launched,due to the increasing request for volte day by day, asus provided a software update to enable volte.snapdragon 210 onwards supports a software update can do the trick

    How to enable VoLTE support in Xiaomi mobiles

  4. Due to hardware limitations, it is not possible to enable VoLTE on Mi 4i via an OTA update.
    VoLTE support on Mi 4i requires additional hardware changes as well as custom firmware which is not possible at this time.

  5. Its true that Mi4i hardware supports volte and it is limited by MI as they ave not enable in its software. The Xiaomi Mi 4i is powered by 1.7GHz octa-core Qualcomm Snapdragon 615 processor. As per the site of manufacturer, this processor is VOLTE compatible.

    This is upto xiaomi to enable this feature.

  6. That is wrong. A firmware update can also bring VoLTE support, requires supported baseband modem though. Since Mi4 is a 4G phone, most probably this trick will work (we haven’t tested)
