Airtel 4G is nice service wherever it is available.Gives 5 to 10mbps download speed. Fastest uploading also 2 to 4 mbps. Speed varies according to location and tower. Gives gr8 speed even in 3g. And best thing 4g packs are priced at 3g pack price. Also support roaming on other some network.Speed is like that you will run out of data if using youtube.
Gr8 for regular official use with limited data and if want movies go with unlimited data plans.
Want High speed wireless service I recommend Airtel 4G.
Good customer Service.
