Airtel — Sim quality

Most disgusting part is 'sim' quality, its very cheap quality that have been in the market when compared to other countries. I took my sim in 2019 october and now september 2020, in a short span of 10 months there is need to replace sim, because of sim quality isn't working.
While i m using the mobile data my mobile suddenly stop working, then i went to mobile store, shopkeeper said mobile is perfect your sim isn't working and suggest me to change.
Plz suggest them to maintain absolute quality for some products
