The answer is Yes but No!!
Since the Jio Phone runs on KaiOS and not on Android, it’s not possible to flash Google Play Services (or install Google Play Store) on the phone.
But you can download and install Google Play Store apps on Jio Phone.
First, open the Official Play Store website to install apps on Jio Phone.
Wait till Play Store has been completely loaded in your phone.
Tap on the search bar and type any of the App name you want to install.
Now click on that specific app to open it.
