I’m Using Airtel Since my Fast Mobile nmbr And My Family Members Also Using Airtel. I’m fully Satisfied With Airtel But Airtel Little Costly Compare to Idea, Reliance, Aircel Etc. But If u Want a gud Network All Over india than u pay little extra money. Airtel 3G And 4G Just Osm and 2G little Slow after Launching Airtel 4G. I’m little disappointed with Airtel Coz they Didn’t gave any Gud offers for regular or Old Customers. I think Old Customers is most important customers for any Telecom Company so Airtel Not Want to loose her Old Customers So Provide a Gud Offers in Talktime, Data Offers And Rate Cutters Also. Coz if Airtel Not Provide a gud offers for her old customers so. Those Customers are Choose other Telecom Company by Port out her Airtel Numbers.So Plz Provide a Gud Offers for Old customers. Thnks
