The phone is based on AOSP android. My cousin also got one. It doesn't have Google play store.
I tried installing different versions of Playstore apk's (from apkmirror). Play store just wouldn't open after installation. Any resolution?
Edit: Can't install gapps through flashing for a few months. I also tried a method from miui forum. Play services kept throwing up an error saying it stopped working. Was quite a task to navigate and uninstall play services.
