Battleground Mobile India released early access, but everyone who registered did not get it. So here is the trick:
- Go to this site BGMI
- Click on early access, select your Gmail it will be registered.
- Go to play store with that Gmail and install.
It will show internal error after you clicked on the early access button, come back and click again you will get the early access.
If you are not able to get that go to APKMirror downlaod apk, data will be downloaded inside the app once you installed and opened.
