I live in Indore and in here the Idea network is working actually good and fast. I can see the network bar full not all the time but most of the time.
Internet by Idea is also good and fast. But there are some problems with their plan:
Firstly, the internet data seems to get exhaust really fast.
Then Idea plan are costly compare to other telecom service.
I am using Idea for like 3 years and more and I didn’t find any trouble using the service expect these two I noticed.
