Did u have volte enabled? If u have volte then u can just force vowifi by dialing *#*#869434#*#*

Basically it'll force vowifi swith to appear in Xiaomi phone setting regardless of telco support. Obviously also need telco support at their end too for it to actually work. After dialing the code then the vowifi toggle will appear in phone settings, enable it and see if vowifi icon appear in status bar. Then check by dialing out and receiving call. Test for a few days, see if your contacts complain can't reach u or not. If they complain then can redial the code again to reenable default behavior.

I did the same and it works fine. Contacted maxis cs to enable volte and vowifi but only volte enabled, vowifi switch doesn't appear on phone settings. Did the code, vowifi toggle appeared, i turned it on and tested for a week or 2. Now I've reset it to default behavior again and the vowifi toggle stays and vowifi still works.

So Maxis VoWifi is working perfectly fine on your F3 with this workaround, no buggy encounters?

did you do the dialer code thing to enable vowifi first?

once do the dialer thing only it will appear the vowifi option in Sim1/2, shown as "make calls using wifi"

i got the notification update. when i tap on it, the update gone. 

2 weeks ago, my F3 suddenly shutdown and can't be turn on or charge. Plug on PC no signal. Can't boot to recovery and fastboot mode.

Luckily still have warranty (March 2023 lol). Decided to send my phone to Service centre @ MidValley.

They said need to replace the main board. Data all will be gone. 3 days later they called me to pickup the phone.

A bit sad all my data can't be saved. Just happy the service is free of charge.
Reminder to all to backup your data everyday.

Edit : My phone bootloader is unlocked with custom ROM. They still accepted it for warranty.

Your phone was only one year old? Damn, hope this is an outlier incident. In Reddit, the X3 Pro was having so many reports of the phone dying suddenly from motherboard failure. The F3 was far and few between.

Just checked..my warranty just expired jan this year...hope nothing happen..kind of scare. My last note 5 last almost 5 years till hardware problem. Change it

So far it works fine. Can't say not buggy at all because i rarely make or take calls but when i did, it works.

I had a Note 5 too, until the display started bleeding purple about 3 years in lmao. To be honest, if my F3 dies with a motherboard failure too soon, my next phone won't be Poco anymore.

Did the number dial and after it says 'VoWifi checking disabled', the VoWifi option appeared in settings. Enabled it but VoWifi doesn't work, guess I gotta ring Maxis.

Thats what I've already said. Of course need to call telco cs first and ask them to enable vowifi at their end. The switch can't magically make wovifi work without telco vowifi sip server.

I called and they said it's already activated on their end. I already had VoLTE working before so they mentioned that VoWifi shares the same profile so it should work. However I'm still unable to get VoWifi working by using airplane mode. Are you on latest MiUi 13?

Well not me personally, did that on my mom Xiaomi. What they said should be right, volte shared some tech with vowifi and if you already got maxis volte working, vowifi should be working too. Just that Xiaomi whitelist which telco to allow vowifi via the toggle. The ussd code only bypass the whitelist and show it on all sim without check.

Did it even work without airplane mode, like does the vowifi icon appear in status bar? Maxis vowifi is weird not like digi vowifi that can use while roaming outside malaysia to bypass incoming call charges by using vowifi in airplane mode. Maybe try with other wifi in case your wifi is the problem. Try with kfc mcd wifi or office wifi or something. I just tried on my own xiaomi, not the f3 but 11t, maxis vowifi still work in airplane mode can dial the 123 and hear the bot cs greeting but I'm not roaming.

Do both VoLTE and VoWifi appear in the status bar at the same time? I've always only ever had VoLTE appear. Well then I will have to try with some other WiFi to see if there is a difference.

nope. volte will disappear when vowifi is available.

Is this maxis? I have tried multiple way.  Can't get it work
