Airtel is a big network provider in india . The schmes n ad shown on t.v. attract me towards airtel n my friends also told me about airtel that it is best . So I buy a airtel sim . The network is good in first week but after one week the network goes slow n slow . I call customer care for this but they said we cant do anything for network . So I hate this airtel network provider . and 3G works like 2G this is the haressement for me . and charges are takes anytime without internet is also sad me . so guys dont believe on airtel.
