I have lived several years in India and it is quite literally one of the last places I would want to be during the pandemic and the economic turmoil it has wreaked.
I think many will stay in Phuket as well since the population will be mostly vaccinated and the covid numbers should remain lower than in other places.
If you are leaving in a month and are fully vaccinated then you can go to Phuket for a week without quarantine and then travel to any open provinces after that so long as you pass a covid test after 5 days.
Sorry to hear this. It is one of the safest countries from covid at the moment so they should let people stay, especially since it contributes to their economy.
