No VoLTE on Boost Mobile for Poco X3 NFC

So I just received my Poco X3 NFC. Before I purchased it I made sure that it supported the 4G bands that Boost/Telstra uses for VoLTE. I went ahead and dialled ##86583## to enable VoLTE and also dialled ##869434## to enable VoWIFI. The VoLTE logo doesn't pop up at the top of my screen and when I go to make a call it changes over to 3G. I swapped sim card slots and restarted the phone, but it still doesn't work. If I pop my sim into my Galaxy S8 VoLTE works straight away.

Does anyone know how to get VoLTE to work?

  • I have the same case with my Mi5s.

    I do not have all 4g bands but from what I read, Telstra provides VoLTE on 700 Mhz (B28).
    Are the toggle available and switched on in the settings ?
    VoLTE activated on your boost account ?

    Can take up to 24h to work as per a Boost representative (not sure if this quite accurate tbh).

    • Yeah I've activated it through the dialler using ##86583## and it's also on in the sim card settings page. VoLTE was working fine for the last 2 months on Boost with my Galaxy S8.

      Not sure what the issue is…

  • Did you dial the asterisks' aswell? I'm with Boost too but with a Mi 9 and I dialed the following to make it work:
    @#@#86583#@#@ to enable VoLTE. Should say "carrier check disabled" if successfull.
    @#@#869434#@#@ to enable VoWIFI Should say "carrier check disabled" if successfull.

    It took a few hours to take effect.

    Edit: Looks like Ozbargain strips out the asterisks :-(. Replace @'s with asterisks.

    • Yeah I activated both VoLTE and VoWIFI through the dialler, and I made sure that they were both turned on in the sim card settings menu.

  • maybe IMS configuration for Telstra is not included in the OS

  • I had my mi mix 2 working for Optus/telstra with these two codes. I am still waiting for poco x3 it's in sorting centre Syd, should arrive next week. I will put in my Telstra sim card to have a try, finger crossed.

  • VoLTE ?

    How can you tell if you have or have not got it? I assume they all use the internet data for voice transmission anyway?

    • You may have a VoLTE icon in your status bar if you have it, also calls wont fall back to 3g when calling.

  • I have been struggling with this for a long time now.
    My earlier thread for my phone was also on the same lines:

    No VoLTE on Boost Mobile for Redmi Note 5 Pro (Xiaomi) Handset

    Which 4G LTE Band is required for VoLTE in Australia?

    … albeit, my handset does not have Band 28. But in the same threads, there are others using Xiaomi Mi A1 and Mi A2 who have reported that VoLTE works. Similarly another person has reported that VoLTE works on Mi 9T and Mi 9T Pro.

    Just having the Band is not enough, the Telco has to support the Firmware on your phone. From what I can make out is that "Mi Phones" get VoLTE on Boost, but "Redmi or POCO Phones" do not get VoLTE. It may be something to do with the firmware, as Mi A1 and Mi A2 will be on Stock Android (no MIUI), so it may already be supported by Telstra for VoLTE.

    Not sure how it works on Mi 9T / 9T Pro, but thats the only other Mi Model which seems to have VoLTE working.

    1. Your phone needs to support it
    2. Your carrier ALSO needs to support it
    3. and you are using your data allowance for VoLTE

    So even though 3rd party resellers like Boost may use Telstra network, they may not have capability to track your data usage

    • Data allowance doesnt get 'accounted' for VoLTE. Data balance is not deducted from your plan if VoLTE calls are used.

      • Rang up Optus and they said VoLTE DOES use up your data

        I will check again

        EDIT: IF data is NOT METERED, would imagine everyone calling international for FREE hehe

        • Having VoLTE doesnt mean you may place an international call.
          You would get charged as per your plan, so if international calls were not included in your plan, you would still get charged for it - VoLTE or not, it is immaterial.

          Just that the "Data Usage" is not accounted for.

          • @djoz: International call centers!!!! Still on hold for Optus technical support now

  • It depends where your phone came from, grey import sites get their phones from Asian countries and they don't have access to all of our frequencies.

    Each phone comes in multiple configurations and model numbers with different specifications.

  • Has anyone got VoLTE to work on the Poco X3 NFC? Regardless which provider you're with Telstra/Boost, Optus or Vodaphone?

  • here is something that keeps popping up: POSTPAID

    VoLTE is available to eligible Optus consumer and SMB postpaid customers using compatible VoLTE phones.

    • Prepaid customers as well now. Need to message and get rep to turn it on, though.

  • Anyone has poco x3 volte working on telstra network?

    • No Volte and VoWifi

  • Other than VoLTE, has your reception been okay with the Poco X3 on the Telstra network? This thread suggests it's not as good as other phones, at least in the posters' location…

  • I have the UK version of the Poco X3 from Amazon.
    Works with VOLTE on Optus. VOLTE sign top right hand and it doesn't fall back to 3G when a call is made.

  • Got my Poco X3 the other day, sadly no VoLTE on boost, but looks like VoWiFi works. Wonder if it will work if using a custom ROM? Has anyone installed one and gotten it to work?

    • +1

      I've installed Resurrection Remix 8.6.5 custom ROM on my Poco X3 NFC.
      I haven't been able to get VoLTE or VoWiFi to work. Even called Boost customer service band they conformed that VoLTE is enabled. This worked fine in my Samsung S8+

      I really like the RR ROM so don't know if I should try to install another ROM just to get VoLTE to work.

      • Damn that's a shame, VoWiFi works on stock at least so that's something.

        Not sure if another ROM might work for VoLTE if that's the case, but not the end of the world I suppose.

        Thanks for checking!

        Both volte and vowifi works on custom android 11 ROMs but it needs abit of work . Mostly finding the right mbn files and fixing Qualcomm USB init , because on custom ROMs the Qualcomm Diag mode doesn't work , so you need to fix it in vendor partition in internal, anyways good luck

        • Thank you.
          Is there a particular vendor partition I could flash in recovery that would fix the issue? Any guides on how to make it all work?

          • @vrsac: I did all this awhile ago forgot the steps , but if you stay on stock you don't have to mess with vendor at all. Just follow this

            • @Walibak: could you please post what you remember about Qualcomm USB init and the vendor files?
              I was able to get a diag port and use efstools to copy mbn to nv items but when I reboot it doesn't stick.
              Any ideas mate?

              NOTE: Fyi - I can open a diag port on stock or custom roms on my POCO F2 Pro.

          • @vrsac: did you have any luck?

            • @mackaqld: I've read the guide linked by @Walibak
              It's a lot of work and there is no guarantee it's going to work. It's basically hacking carrier data in EFS partition that also holds IMEI information. I'm afraid that if EFS partition is accidentally corrupted, that the phone won't connect to mobile network.
              I'm planning to flash a new ROM soon, so, I'll try that first and the "EFS hack" only as last resort.

              • @vrsac: If you backup your EFS in twrp, you can restore it if you muck it up..
                I have been playing around with mine, and had no success. I have written the telstra mbn to nv items but it doesn't stick after a reboot. I haven't needed to restore my efs backup. Not sure if your phone will have the same issue with the mbn not sticking.

                I hope Xiaomi fix this issue, not sure if the actual issue is with the mbn file or something else in the firmware. All the Telstra mbn files are the same on the sd 865 devices since the start of Android 11 and doesn't seem to be changing so it's possible that they won't fix it. They probably don't know there's an issue.

  • Anyone have any luck with Volte?

    • Just did this on my Poco m3 pro 5g. It did not work until I put both codes in. Then it worked perfectly. I have Boost and 3g reception can be a bit spotty where I live. So 4g, volte not working was a problem. I keyed just the volte code and nothing happened. After inputting the call over wifi code, the menu option appeared in the sim settings. I was able to make a call with perfect clarity. I used an app called netmonitor to check that the call was actually made using b28 700mhz. So definitely 4g Volte now works.

      • @Gratt: Can you plz share both the codes that you are referring to. Thanks.

  • Tried to follow that guide but trying to set those props resulted in Selinux denials.

  • Old thread but just want to let people know that I ended up buying an Optus sim to try out, volte/vowifi works flawlessly on the X3 NFC.

    Still no luck for boost with me, but worth getting a cheap Optus sim if you want to test out their reception and whatnot.
