6 years ago when I first got mobile phone all network call rate was very low .but during last few years all network is hiking their call rate day by day. then I was looking for a network which will be chipest from the site of call rate.
Then I switched to aircel. still now it’s chipest in all network .but when I put a internet pack on this a horrible experience faced.even in 3g network .now a days we all use duel sim mobile phone, so you can use it for only just phone call and use others for else work. as I am doing .
