I used to think that idea is a good network but let me tell you my expreince with it. I will not say it is worst, but yes this is not for me, I have very high demands. I expected to get a good network inside my house and a high speed internet as it was a 4g sim but, the speed on the network is not up to the mark.
The speed is very decent, it will feel like 3g, not like true 4g in 4g a mobile get around 30-40mb/s but it is not with idea network they say that this is fast network! but this is really not.
The network coverage is not good if you are a traveller like me!
