I am using idea for 2 years I can say that idea is a best tele communication network I have ever seen never your call will disconnect , no network coverage problem, no internet problem . I did not face any problem in idea from the date date I buy the sim and now. Idea prepaid service is very good because I am using that only. Everyday you will get new offers on internet , calling , messaging etc . I am doing 249 rs recharge of unlimited 2 g internet in that speed was fast and browsing also work very fast after the limited usage also the speed was good. Now recently idea has launch its 4g network which is very good. Recharges are not very much costly at Rs 19 you will get 1 hr 4g unlimited data the speed was mind blowing I have also done this recharge. Network coverage is very nice and customer service was cool and helpfull. Charges and billing are less. Become the member of idea family and enjoy the world.
