I bought idea sim card 3 years before. At that time network was better. I also used idea number for bank account. But now that network is very poor. 4G internate is also poor. Since the monsoon has started I never got network. They were asking for minimum 35 rupees recharge of keeping service active. I was also getting disturbance due to unwanted sms like quizzes, offer etc. Hence instead of blaming idea I chosed another operator.
