I am planning to switch to Idea once my current balance is utilised.....Coz Idea is way too cheaper than Vodafone. I have 3 reasons to shift to Idea....1) I dont remember what pack i had taken on my existing Idea connection, that from June 2010, till date, i am charged:1p/sec on outgoing - ROAMINGNil on Incoming - ROAMING.....Whereas Vodafone - it charged me Re.1/min on both In & out.......that too, wasnt per second billing - talk for 1 second also and that Rupee is charged.2) STD calling also is @ 1p/sec from my home circle or even on roaming. But on Vodafone, it becomes Rs.1.3/sec on Home circle, and never dared STD on roaming - so dont know the charges.3) Network......i have noticed tis many times - Call dropping is very less in Idea. I have to call up 3-4 times if i call up using Vodafone (Ofcourse, that costs extra because every 1st second of a call i am charged 1 Re.)Whereas in Idea - once i call up, the call doesnt drop, until i disconnect the fone.There were many other features which i had received on my fone via sms, due to which i have made up my mind to switch to Idea.
