Are You An Airtel Subscriber in Mumbai? Here’s How to Enable VoLTE Services in Your Supported Smartphone

Bharti Airtel, a couple of days ago became the second Indian telecom operator after Reliance Jio to offer VoLTE services in the country. Although Reliance Jio is offering pan-India VoLTE services, Bharti Airtel is rolling it out in a phased manner, meaning Airtel VoLTE services will go live in select cities first. The pan-India roll out for the same is expected to be done by March 2018.


So, for now, Airtel has VoLTE coverage only in Mumbai. However, we have seen numerous comments from our Airtel Mumbai readers saying that they’re not able to register on Airtel VoLTE network. There might be two reasons for this:

1) Smartphone compatibility: Yes, you heard it right. Not every VoLTE smartphone supports Airtel VoLTE service because the manufacturer has to separately enable a software patch, which can be done with a software update. For now, the Airtel VoLTE supported smartphones are:

Apple iPhone SE, Apple iPhone 6, Apple iPhone 6 Plus, Apple iPhone 6S, Apple iPhone 6S Plus, Apple iPhone 7, Apple iPhone 7 Plus, Samsung Galaxy J7, Samsung Galaxy A8, Samsung Galaxy J2 Pro/J2 2016, Xiaomi Mi Max Prime, Xiaomi Redmi Note 4, Xiaomi Mi Max, Xiaomi Mi5, Gionee A1, and Oppo F3 Plus.

These are the supported smartphones for now, but the list will keep on increasing to add more smartphones to the list. Keep checking for the updated list.

2) Incorrect Settings
There are some users who’re using a compatible smartphone, but unable to register on Airtel VoLTE network, which is underwhelming. The only reason for this might be the incorrect settings. Airtel has issued a universal method for all the compatible smartphones to register on the network. Follow the below steps to register on Airtel VoLTE network.

  • Check for a software update: If you own any of the smartphones in the above list and still dont get Airtel VoLTE, then the first thing you need to do is to head over to the system settings and check for a software update. If you have any pending update, update the device right away, which might enable the Airtel VoLTE settings on your smartphone.
  • Network Settings
    To make the Airtel VoLTE work, you should be on 4G LTE network. So, choose your smartphone’s network settings to 4G/3G/2G/auto, so that your device will register on the Airtel VoLTE network. Also, do check whether HD calling is turned on or off on your smartphone.
  • For Dual SIM users
    Customers with dual-SIM handsets have to ensure that the Airtel 4G SIM has been inserted in the data SIM slot/slot 1 and network mode has been set as “4G/3G/2G (Auto)”.

By following these steps, your Airtel VoLTE network should show up. If not, just reboot the smartphone once. If you still can’t able to get the Airtel VoLTE network, we suggest you head over the nearest Airtel store for a fix.

[…] You can activate Airtel VoLTE services by following the procedure we’ve written two weeks ago. Also, Airtel has extended VoLTE support for some more Samsung devices, and the operator promised support for more devices by the end of this year. […]

Since we are talking Mumbai, how is TelecomTalk user community experience with Vodafone?

I have noticed the 4G connection keeps dropping to 3G (and in recent days even Edge!). Speeds are sometimes OK, and unusably slow at other times. The variation in network quality is far too high for a professionally managed network.

Looks like Vodafone is desperate to save cash ahead of the merger with Idea. But, if they treat their top market like this, they will start losing customers.

You have to realize that Vodafone doesn’t have the required amount of spectrum needed for such a data heavy market. Mumbai has one of the highest data usage compared to subscribers and overall available infra. Airtel and Jio have more spectrum so speeds and even coverage is better than Vodafone at many places. Vodafone also has the most subscribers in the circle so it sucks that they are not using the spectrum that is already available with them to serve their high paying customers. If you want reliable voice usage then stick with Vodafone if you are more into data… Read more »

Indeed. The quality of Vodafone has gone down the drain in Mumbai. Their 4G as well as 3G network is highly inconsistent these days.

HD calling to Jio from a VoLTE enabled Airtel connection is possible? Or its just limited to VoLTE enabled other Airtel connections?

HD Volte calls b/w operators r currently NOT active worldwide. Reason being Operators need to create IMS trunk at Voice gateway/Router level among themselves to connect to other operator like local area network and this require special intent/willingness to do this and technically requires dedicated voice bandwidth at router level to carry Volte HD calls among them… So technically it is feasible but Operators do not do it to create monopoly….

Actually, HD voice is part of the LTE standard and not a separate feature. You are right that it needs codec support at the IP voice gateway, but this is very easy to do. In several markets, cross-operator HD voice calls are already in place. The initial problems for Airtel will be elsewhere. The LTE network needs a lot of optimisation to work well. Otherwise, calls will drop or just not connect. The phased deployment should ideally let them learn from the first few circles, but the radio network optimisation often needs to be tweaked locally. Moving to LTE quickly… Read more »

Isn’t their system will crash ? If they allow Volte for all ? That’s the reason they are selective for some time
