I am using Idea network I ported in my two sims to Idea postpaid network using national mnp. I was very happy with my new connections as I was using Idea network for the first time. But What I experienced is that it takes too much time to connect to another network. many a times it shows no network even today it shows limited network It is irritating me a lot. also the data ( internet) speed is very low. For net I have to purchase one more sim. I went to some another service provider for porting my both idea sim to that network but they say ur connection is post paid so porting is possible only postpaid to post paid but I to port it in prepaid then I made request to Idea to convert my postpaid connection to prepaid then one of my connection remained out of order for two or more days. now I am waiting for the time when I port my numbersaz to some another network really it irritated me a lot.
