Airtel — airtel number is showing invalid and inactive

Address:

560017

I've been using mobile no :- [protected] (From karnataka - bangalore region) from 2008 till present. It was my postpaid number from 2008 till 2016 and i've changed it to prepaid in 2016 as i had to frequently travel out of india on short work related visits to foreign countries so that i can recharge and use when needed.

I've changed this number [protected] from post paid to prepaid and activated international roaming as well so that i will get calls/messages when i was on travel out of india on business visits and it was working perfectly.

Now that i notice from oct 2017, my sim card is not working and not detecting any signal. When i tried to recharge it is saying "the airtel number is not correct", which is worrying me.

Can you explain me what happened here? Have this number is blocked, if so, please reactivate it and i continue use our airtel services in india and outside india.

Considering i'm airtel customer from 2008, please help me in this regard. I badly need this number as this is my primary point of contact number from 2008.

You can reach me on [protected]@gmail.com

Appreciate your response.
