Idea best network and also best for internet. Review on Idea Mobile Operator

Hello frds. I am shivam ojha and I use idea for internet and I feel better for its performence but some time its network very slow. then I get alot of problem so I always face the network issues with idea, sometimes signals are lost, the voice is breaking and other network related problems. so whenever the duration of that plan ends, the money straight away starts deducting from my balance. What I think is, one day before, they should send a message that the plan of yours is expiring tomorrow. Please recharge.Every time when I travelling to differnent cities or moving from metro from one place to other network always goes up down . no internet working while in travel or in roaming . and there is only one infinity plan which is very costly. there should be another infinity plans with less cost. and it automatically on off the internet services while using .
