I use two SIM cards, Jio and Airtel. But I can use only Jio network. But sometime when I did not got full speed from Jio then I use airtel's network. And literally airtel speed is double comapare to Jio. Where I live there is good speed of Airtel. But I can say that this doesnt matter. Customer support can disappoint you if you are using pre-paid connection. Because any operator can not solve the problem within minutes/hour. They need some time at leat 24 hours to ensure that what is the issue with the particular handset or network. I use postpaid connection that is little bit costly compare to pre-paid but what would be the difference if pre-paid and post-paid billing will be the same. But overall it's nice operator. It's much better than Idea, Vodafone, Docomo etc.
