Well u can actually get numbers of website which sell mobile spares online. Just look for “ mobile spare parts” on google and u will find range of sites all they way from china to india .
But ordering online for mobile parts is a costly method if u are dealing in this industry as they have higher charges then the local market for the same type of product.
Better way is to either opt for a mumbai or delhi based supplier .
I myself am a mobile spare parts dealer from mumbai.
