Aircel though providing services at comparatively lower rate but services are very bad. network does not work at all places . I have bought aircel SIM 1 yr back but .not only the network but also the customer support is not proper. charges are deducted automatically any service is started automatically .I ll not advice to buy SIM of aircel since service are not up to mark. My advice . Use only that network which provide network and customer support do not go lower recharge and offer.
Thanks
