Guys I Was using airtel network. One of my friend told me to use Vodafone network. Realy I felt bad. Bczz automatically cal get disconnected. Bcz Vodafone network. Its one of the worst network compared to other network. And 4g network works as 2g network. After opening videos in YouTube it is simply rotating rotating til 5 to 10 mnt. That experience was horrible. Dont use Vodafone network frndz.
