Untill now I was using airtel but I was about to port bcz of the speed issue
but now our area is covered under 4g and its juz marvelous.what a speed
and also one thing I mostly like about airtel is that the customer service team is accurate and is so helpful unless like other operators but please reduce the waiting time
bcz when ever I cal customer care it takes soo much time to contact
but regarding this the whole network coverage and speed at our locatoion is nice as I only use this sim mainly for browsing and downloadingAirtel is the fast growing network in the world
Advantages
-high speed browising
-unlimited night packs with low price
-it has 4g

-3g supports in 60% of villages in india
Disadvantages
-high price data packs
-most of villages dont have airtel network
-4g is supports in only famous cities
-some times slow internet speed
