I am a completely satisfied with the Airtel 4g LTE connection. Though it has not been a smooth ride, as in the beginning I had faced a lot of connection problems, but Airtel resolved it within 2 weeks from the date when I purchased it and since then I have not got a single complaint. There is no problem with the connection at all. The speed of the connection varies from 8 to 21 mbps anytime throughout the day. The main thing to notice is that the cost is higher when compared to other services, however the quality of service overtakes it.
I would love to recommend Airtel 4g LTE dongle to my friends, relatives and my family members. Also, the people who are reading this review!
