where to sell imported android mobiles need suggestion

as the title says, i want to sell brand new imported android mobiles in India at discounted prices. a few years back i used to sell on ebay.in without gst number. now ebay is closed and remaining sites like Amazon,, Flipkart ask for gst number

next week i will be getting around 5 of mi note 10’s

so anyone have any sites or forums where we can sell electronics like external hard disks, mobiles etc?

ps : olx is shitty for new mobiles

thanks in advance
