I am writing this review because I used idea 4glte.for 2months and I am very disappointed with the network coverage.idea provided 4g network for their customers but the network is very slow as compare to another 4g networks like jio, airtel, vodafone.when you use the idea sim for 4g network you feel llike you are using 2g network because it has really very vad network and signal strength. Idea 4g calling voice is also very bad. And at last I request you to not use idea4g network because is totally waste of money. Thanks for reading my review.
