Mi A2 is one of the most popular smartphones from Xiaomi in India due to its clutter-free software experience and regular monthly security updates. Recently the device has also received Google’s latest Android 10 with January 2020 security patch. Due to the popularity of Wi-Fi Calling, many users were expecting the feature along with the Android 10 update. But it didn’t happen. Even though the company is expected to release the WiFi Calling feature in the upcoming software update here is an easy way that allows you to enable the WiFi calling in Mi A2.
Note: GizArena is not responsible for any issues or damage or any kind of data loss to your device. Follow this tutorial on your own risk.
Enable Wi-Fi Calling on Xiaomi Mi A2
In the first step, you’ll have to disable the Wi-Fi calling check. The process is very simple and doesn’t require any 3rd party app installations. All you have to do is:
- Open the Dialer
- enter this code – *#*#869434#*#*
- Once you dial, you’ll get a small notification saying “Vowifi carrier check was disabled”
Enter the Code 
Confirmation
Once you disable the VoWiFi carrier check, now enable the VoWiFi in the Dialer settings. To do so:
- Open Dialer
- Tap on Menu icon on the top right
- Go to Settings
- Select Calling accounts
- Then, select your Network Operator (Ex. Airtel, Jio, etc.)
- Select the option Wi-Fi Calling
- Turn on the Wi-Fi Calling by tapping on the Toggle
That’s it. You’ve successfully enabled Wi-Fi Calling on your Primary SIM. Now, follow the same method (Calling accounts -> Select the second SIM) to enable Wi-Fi Calling on your second SIM. This method is tested successfully on the Airtel network with BSNL ISP. Check out the screenshots below.
Note: If you experience any issues with Call Quality or Network, disable the Vowifi carrier check. Simply Dial *#*#869434#*#* once again which disables the VoWiFi and you’ll get a message saying “Vowifi carrier check was enabled“.

Wow it’s mid 2023 and i just tried this on my international Xiaomi Mi Note 10 and it works! It disabled the checking and I see the option. I can’t toggle the wifi calling for some reason but I think it’s an issue on my side as this sim has not connected to this network in this phone yet ( no cell service here). Will try tomorrow and update you all.
Thanks so much Satwik. I am very very thankful to you as I was facing network issues for long until I read your article. Now my phone is working fantastic. I was not even aware that there is wi fi calling available in MI A2.
Thanks once again buddy.
You’re most welcome Kirti Shukla. I am glad the article helped you.
Any way to force or prioritize Wifi calling over normal call?
As far as I know, if you’re connected to WiFi, priority will be given to WiFi calling.
Successfully enabled but there is a problem with network.
As I turn off my wifi emergency call/no service is shown on Airtel sim.
And also unable to send or receive messages.
Please help
Restart your phone and check. There may be issues with the SIM card also. Insert the SIM in another phone and check.
I have enabled referring to the steps mentioned above.
Even though i have connected to my wifi, wifi calling doesn’t work. At my place there is no network for airtel indoors, will wifi calling work in that case or does it require atleast minimum mobile network to be available for wifi calling to work?
You can make wifi calls with little or even no cellular network. But, your internet service provider should support WiFi calling. WiFi calling depends on cellular Network, phone model, and ISP.
Does it works for JIO?
No. It doesn’t support Jio as of now.
Thanks a lot for the trick, it works! Is there any way to enable it for text message also as it will be helpful with OTP ?
awesome, thanks
You’re Welcome Sri 🙂
Is this option works with Jio as I have 2 sim cards? One is Vodafone and another is Jio. Whenever I receive calls on Vodafone it shows that it’s on wifi but not for the Jio
As far as I know, Mi A2 doesn’t support WiFi calling on the Jio network.
It’s been a tough day, month, year, etc.
I just really needed a win today, and this trick worked instantly. Thank you. Seriously.
Today surprisingly WiFi calling started working on my VI (Idea) card as well. Looks like VI is enabling it phases. Anyway thanks for the trick.
Hi, Thanks for the update. Please mention your ISP and Location.
Hello there, thanks for the trick that you have shared but please research how can we enable wifi calling over the Jio network using Mi A2. I have two sims on my phone Sim1-Jio and Sim2-Airtel. For both of them, I have enabled wifi calling for airtel it is working absolutely fine but for the Jio it is not don’t know what’s the reason. I also experience that person on the other side of the call not able to hear me while calling keeping wifi connected on Jio. But one thing I know for sure that it can work on Jio also because I have seen it once when I was receiving a call on Jio it was catching the call through and the Jio WiFi HD call was written at the top.
Does anyone know if it works with VI? I have heard that WiFi calling is now available in Maharashtra on VI.
Is this feature available for BSNL Sim in India?
I have not tested it. But, VoWiFi on Airtel works with BSNL ISP.
Thank you bro its gonna be very helpful for me
