Bharti Airtel recently launched the 4G services in Delhi. It has already launched 4G services in many cities such as Chennai, Mumbai, Kolkata, Mysore and Pune. The trials in Delhi started on 19th June’15 and the everything looks great right now. Although it’s still in beta phase, still there are no major issues with the network.

Airtel already provides the best 3G network coverage and speeds in Delhi. Another interesting thing is that, as of now in the roll out phase, 4G services can be availed at 3G prices! This means all the devices which support 4G LTE can get 4G data at same price as 3G.

What is 4G?

For those who are unfamiliar with 4G LTE, it stands for Fourth generation Long term evolution GSM network technology. It is the successor to 3G mobile service, which is available all across India. Interestingly, 4G is much more advanced than 3G and provides 5x more speed than 3G with download speeds approaching ~50 Mbps. Crazy fast eh?

Airtel’s 4G services are the first in India to leverage an integrated FD and TD network which will deliver the fastest 4G experience and superior network coverage.

How do I get it?

Well you do need a new 4G enabled SIM card, but don’t worry, the best part is that Airtel is delivering the 4G SIM at our doorsteps without any charges.

So, how’s the network and speed?

Now, talking about the network, 4G is working very well in mostly all regions of Delhi. I’ve used 4G on my Oneplus one, and it’s working fabulous. I’ve been getting speed up to 25 Mbps download speed constantly without any downtime. I only lost the network for 15 minutes in the evening, but since then has been doing very consistent. Also, sometimes it may take a few minutes to switch from 3G to 4G depending upon the signal strength. Occasionally it may even require a reboot, but it’s a rare case.

Airtel 4G speed - Airtel 4G LTE Review

~25mbps feels like a new breeze!


Airtel has done very well till now in providing 4G services across many cities in India and now they have entered the Capital too. As of now, it’s a sole 4G provider in Delhi but Reliance is also getting serious to invade the telecom market and especially 4G business. Reliance will be launching Reliance Jio by 2015 end. The price war between these two will surely be there. Mukesh Ambani, Chairman of Reliance Industries, is now the largest holder of 4G spectrum in India and it’s the first operator to hold a pan-India licence. This will surely disrupt India’s telecom market. Airtel will surely receive a tough competition from Reliance. It will be interesting to see who emerges at the top, but at the end, it’s customer(us) who wins! 🙂

Do try Airtel 4G LTE services if you own a supported handset and enjoy 4G at 3G prices till it lasts. Share your speedtest result below and see if you can break the 25mbps barrier! 😉
