Airtel — my airtel number showing invalid sim

My airtel number is +91-[protected]. I am using this number from 2-3 years.

I am getting invalid sim problem from yesterday evening. Please request you register my complain. Always i recharge this sim with 3 months unlimited pack, currently also this pack running and it will go coming 2 months.

There will be no issue like kyc because i purchase this sim by adhar card only. Infect if there will be any documents or any other update required then i should receive messages/alrert from airtel but i don't.

My alternate number +91-[protected].
