Vivo X Fold
I am currently with Fido for my cellular phone service running a old import( 2016), Huawei Honor Note 8, from Toronto, Canada area, and interested in the Vivo X Fold and this Fido support webpage shows that it should work along with Gishan Canada for Fido APN settings for the Vivo X Fold but I am concerned after hearing that the Vivo X Fold VoLTE is not working in Canada from senior forum member Frcraig, despite all of his efforts.

I have read about the Vivo X Fold phone in general to understand about it's issue being a Chinese only ROM and most likely no Global Rom is coming for software ( I currently own and have dealt with this the past 6 years on my Huawei Honor Note 8). I can also live with it's limited multi-tasking (i.e. hardware quality/form factor amazing and hope updates will only improve the multi-tasking in the near future) I also understand that amongst the top foldables in similar full size phone format/foldable format: HUAWEI Mate X2, Vivo X Fold, Oppo Find N, and the Samsung Fold 4 are the only ones at this point (Surface duo 2 is more a two screen device with a distinctive separation/hinge in the middle) that compete with each other. I am not a fan of the narrow front screen of the Samsung fold 4, hence the Vivo X Fold direction.

For the Vivo X Fold I understand from a senior member here on the forum, Frcraig (Thanks so much for all of your efforts and sharing thus so far) that VoLTE on this phone is not available from Canadian carriers, because they did not pay any of the Canadian carriers the VoLTE certification, and the reason why it can't be turned on. Without VoLTE, the phone will drop to 3G if available but because 3G in Canada is going to be phased out starting in Dec 2023 and generally not available in the States, this is a major concern for people interested in this phone if in Canada.

I am hoping that there can be a possible a resolution to this and started this thread to explore possibilities and/or solutions as this is a major concern!

Would like to know if anyone in Canada has been able to get the VoLTE to work/turn on?


I understand that it is greyed out and can't be turned on in the mobile settings- maybe because:
1) it hasn't been certified (Vivo has not paid any of the Canadian carriers the certification fee) even though it works on most bands including 5G in some cases?
2) sim card is not the latest, and therefor can't offer the VoLTE option?

I spoke to a Rogers technician from technical support today, speaking about the above VoLTE issue, the issues that Frcraig is already experiencing with his new Vivo X Fold. We spoke about the phone bands in general should work according to the phone bands it offers. Rogers Technical support, the lady I was speaking to, Stephanie, for over 30 min, had also put the question on their live global message board to see if there was any specific answers, and received mixed answers- i.e. yes and no, and did not have a definitive answer, but 5 points were made:
1) Can not give a guarantee that the phone will work with VoLTE and not aware of this licensing issue
2) Should work as it does have the 4G and LTE bands - make sure you have an updated Sim Card
3) Confirmed that the 3G is going to be removed in the near future (Dec 2023, after speaking to Frcraig)
4) She Suggested to try a BIOS code to switch it on: "*#*#4636#*#*" on the phone dial pad, as it is a universal code to switch that radio on if it is off, or turn off and back on to reset it - I found a video showing this process using the Redmi Note, @ the 5 min time stamp - Note also very important, prior to doing this, the Sim Card in your phone should be relatively new, and if not get yours replaced, so the sim card has that option/ability to use the VoLTE service from the updated current Sim Card hardware
5) Suggest to use Google search term: what to do if volte is not working - for more information

I am also wondering if this phone absolutely does not work with the VoLTE, that maybe after the 2023 3G removal, that Canadian carriers will update/allow at that time, as I understand the phone can work on the VoLTE as it has the 4G and LTE bands on pretty much all the Canadian Carriers.

Hopefully this community forum and interested parties can find a solution to this VoLTE problem, that I am told is an issue,
so those who do have the phone please confirm that you have the latest Sim Card and have tried the steps above
and/or if someone else has work-around solutions... maybe through rooting the phone or something?

Message to https://www.vivo.com/en/support page through their email
(also commented on their Facebook page: https://www.facebook.com/vivocareGlobal a quick question also)

I am in Canada interested in getting the Vivo X Fold, but finding out that Canadian carriers (main ones here in Canada: Rogers and Bell) from local XDA Forum on the Vivo X Fold (https://forum.xda-developers.com/f/vivo-x-fold.12651/) do not allow the VoLTE 4G to be turned on here in Canada even though carriers support 4G and LTE bands on your phone.

VoLTE is the major Voice Over LTE 4G communications standard protocol, that allows us in Canada with local carriers to talk on the phone with others.

See forum feedback from XDA member that is in Canada with your Vivo X Fold phone:
https://forum.xda-developers.com/t/...e-fence-as-to-which-one.4473827/post-87216075
for his feedback and efforts to get VoLTE to work, i.e. it is not working!

Is there a reason why the VoLTE 4G is greyed out and can't be turned on, on the Vivo X Fold her in Canada, thereby making voice phone calls not possible on your phone through this standard voice communications protocol?

There are a lot of interested people here for the Vivo X Fold in Canada that want a quality foldable phone and don't want to use the Samsung fold because it is too narrow on the front screen,
but looks like we are forced to get it as it is the only foldable that will work on Canadian carriers! Your phone is the only other possible choice BUT DOESN'T HAVE VOLTE 4G WORKING with any of the carriers here in Canada!

Have confirmed this with Rogers and Bell putting their current Sim Card in, and the option to turn on VoLTE is greyed out, i.e. can't be turned on by either cellular service.

I know T-Mobile in USA, the Vivo X Fold works on their network, but why not at least one carrier in Canada?
(There is talk that Vivo got their phones certified for use with T-Mobile in the USA, but no carriers were certified (paid registration fee so that it works with carrier) in Canada, leaving us Canadians that want to use any of your phones, not able to because the VoLTE can't be turned on in the phones mobile service settings.

Can you tell me why this is not working and/or reason why VoLTE is not able to be turned on?

Is there anything that can be done about this?

For what its worth, you can enable VoNR for stand alone frequencies. in developer settings or with a dialing code. The problem is that while these phones can connect on n78 Stand Alone networks, (3500mhz) the Canadian telecoms have just started using this frequency and it is only in a few major cities. They are also not using Voice Over 5G (VoNR) so even when the n78 band reaches your area, you would have to wait for the carrier to switch their technology for voice calls from VoLTE to VoNR. So far only T-Mobile (in Seattle and Salt Lake City) have turned on VoNR.

So 5G works but VoLTE 4G doesn't! Yeah, I see that band for Rogers, Bell, Telus, Virgin, and Koodo. Do you think that the VoNR may be up by Dec 2023, in large citiy like Toronto... maybe there is light at the end of the tunnel for the Vivo X Fold voice communication then?

I called Rogers and asked that exact question, and they said VoNR (Vo5G) "isn't on the horizon". In the US T-Moblile has switched it on in two test cities - Seattle and Salt Lake. Rogers contracts with Ericsson for their VoLTE and 5G technology, and Ericsson has rolled out VoNR for other clients in other countries - so it is coming, just not soon. I'll cross my fingers it is here before Canada shuts down 3G.

As an aside for those facing the issue of VoLTE not being enabled on this device with Canadian carriers, there is a work around to voice calls dropping to 3G (and therefore no voice calls once 3G is shut down). I subscribed for $10 per month to a Google Voice business account, which gives me a Halifax, Nova Scotia phone number and calls placed with the Google Voice dialing app go out over mobile data, so I can place voice calls via the 5G network. I can't tell the difference between voice quality on VOIP over 5G and regular 3G voice. These calls do consume mobile data (as opposed to unlimited voice minutes) but I ran a log to see how much data these calls were consuming, and for the past 30 days I've used Google Voice for 1,800 minutes (30 hours of talking!) used just over 1 GB of mobile data. On my 80 GB monthly plan I don't know how I could ever exceed that even if I let my wife talk on the phone : )

To clarify though, for my understanding, the Vivo X Fold and other Vivo's for that matter for the most part depending on bands and the carriers here, will generally work on the 4G and LTE, and 5G if available, but not on the VoLTE 4G (which is voice over the 4G and LTE as a communication protocol for regular standard voice phone calls... but because Vivio didn't certify/pay any of the Canadian carriers, the sim cards will not allow you to turn it on and/or allow you to use it even though it is just a software switch as the phone could work as it does with other carriers such as T-Mobile in the States. - Hopefully I am correct so far....

So, the next question based on what you mentioned about the Vo5G.... would that not also required Vivo to have certified/pay the carriers upfront to use that communication protocol through the sim card when it becomes available (voice over 5G), as some of the carriers offering the 5G Bands with the Vivo X Fold are already running off the 5G for Data.

To have voice over 5G (Vo5G), isn't it similar to VoLTE 4G's lack of certification/payment to the carrier from Vivo, i.e. if they didn't pay for VoLTE 4G, then they surely didn't pay for Vo5G also, right?

Using subscription VOIP over 5G as a monthly cost is a great idea and patches this problem of the voice calling when 3G is dropped with and added cost to your phone service. As you mentioned all of those calls equate to a small amount of your data which is good... so an option that allows you to pay a little extra to have a call service better than Skype is a way-out, to still have phone service if you have a Vivo and no 3G for here in Canada.

Side note, I use a VOIP service when I got rid of my Bell landline for the house, which looks like it can be also linked to a "softphone" that I am already paying for, so there is that...
I never bothered to set-up on my phone, as I use the cellular service for my voice calls.

LOL, you have me thinking here, maybe the Vivo X Fold may be still be a possibility... if I could live with this... on the fence with both, Ugh... Samsung Fold 4 revile and pre-orders start Wed... I know you already suggested the Samsung as your choice now that you know about this VoLTE... just that the Vivo's front screen improved width, quality material/feel is a big weight with the tradeoff being no s-pen, better software-multi-tasking/apps... oh and working VoLTE for this side of the earth...
if I went with Samsung, I probably get their new ear buds and watch also as I don't have either. I think I am going to the store again and look at the Samsung Fold 3 in my hands again... every time I have, it is just so narrow and I am so use to my quality phone with the 7" screen, I have used since 2016.

VoLTE options only appear by virtue of the carrier check and SIM, however Vivo has chosen to include VoNR options in the firmware that are not carrier check and SIM dependent. There is a switch in Developer Settings (which can also be activated with a dialing code) that enables VoNR.

Just to complicate your purchase decision, several tech industry leaks in the past two days have suggested Vivo will release a new foldable (being dubbed "Vivo X Fold S" by Gizbchina). One Indian source said it may launch in the next few weeks and include a global version with FunTouch firmware.

frcraig, You keep surprising me with your in-depth knowledge and nuance's of technical detail.... so Vo5G/VoNR is not going to be a problem then, when "eventually" we get there on this phone. Lol, I think you have more insight and information than calling a Tech Support at a carrier, lol... thanks for the explanation and info.

Oh man, I confirmed with a search, one on Aug 8 & 9, you're right on the ball with this. Bigfire member on another thread here, was asking about this very thing.

You know, I was testing out a Fold 3 again today, thinking to my demise that this is most likely going to be the phone I will be reluctantly getting because my phone is really long in the tooth, Samsung has a monopoly here in Canada on the folds, and the fact that Vivo X Fold has the VoLTE issue which I think is a big negative.

Now that you have pointed out this Vivo X Fold S, and reading about the leaked improvements, hmm... two weeks.... I don't know, was intending to pre-order the Fold 4 tomorrow, and now have more questions.

If it is going to have the Funtouch Global version, does this mean that it would likely have VoLTE licensing... you had mentioned earlier that all Vivo phones will not work here because no VoLTE licensing here, with Canadian carriers?

Side note, the Xiami Mix Fold 2 just got teased and is thinner (5.4 vs 6.28 Vivo X fold vs 6.4 Sam Fold 3) and with the flat fold will be a lot thinner than the 14-16 mm of the Sam Fold 3.

on the one hand I am disappointed with the development and I am hoping it's a small spec bump. But if it provides an ease transition between x fold and x fold s (e.g. fun touch installation) it could be very compelling.

I think that project is just for the people who are rooted and BLU to try.

The VoLTE issue on Canadian carriers applies equally to the Origin OS Ocean and Funtouch versions of Vivo Phones. It also applies to Xiaomi phones (they release their new Mix Fold 2 tomorrow) but you can disable carrier checks and enable VoLTE on Xiaomi phones with a dialer code.

This is from Big WhiteDwarf in the comments section to me

"I live in Canada, too. In terms of volte, I unlocked my Xiaomi phone and flashed the xiaomi EU ROM, updated the Google carrier services component, then volte just works. I'm not sure if the Chinese ROM works the same way, but it can be done via software tweaks most likely. But to be honest, I don't really notice much difference with volte on or off and I don't really make calls too much these days. Btw, mix fold 2 won't get the EU ROM."

.... Not sure but you can only do this if you can get access to the bootloader which I understand in recent security update, that is no longer available now.

Finally received a response from vivo Customer Care about the VoLTE on the Vivo X Fold:

"Thank you so much for your email and we are sorry for the delayed reply. According to your email, we are sorry for the inconvenience. We appreciate your interest in purchasing our products. We are very sorry to inform you that our service is not available in Canada. Also like to inform you that, all our handsets have not yet been tested to see if data, Volte, and network service is compatible in another country. However, please note that we are still expanding our overseas market, if there is no official store in your country temporarily, we do not suggest you purchase vivo Phones from other channels since it’s inconvenient for you to repair the phone if is damaged. Also, we can not provide any service for other problems. We are not available in Canada right now but don't worry we are take your dimand as a suggestion and forward it to our concern team. Hope they will work on it and you will understand this fact."

So, for Canadians, no VoLTE is a big issue, and they are straight out saying not to get their phone.

a japanese figured out how to unlock volte in japan. but u have to unlock the bootloader, root and patch an img file with magisk. then again, it's a risk for doing that. and it might not necessarily work in canada.

Thanks for sharing as instructions look promising! Having VoLTE access here in Canada would do two things, allow us to import and use this quality form factor phone in Canada with Canadian carriers as a main driver and therefor give Samsung Z Fold 4 some over-due competition which is badly needed.

There is a rumor that there is a Vivo X Fold S edition coming soon and may have a global rom.... I similar heard that the Oppo Find N Foldable will also will be coming out with a global version, and then there is the sleek thin Mix 2 with its great form factor, although software is ? and not refined as Samsung's.

If anyone in Canada (frcraig, rocky272727....) is willing to try this unlock procedure, please share here so we know if this is a possible fix for the VoLTE. I am sure the appreciation would go a long way, as I was on board with the Vivo X Fold with all of its concerns, but VoLTE is the big one that has stopped me from ordering it and have preordered the Z Fold 4 instead.

Side note: Isn't the bootloader now locked with a recent June security patch, i.e. making it impossible to unlock the bootloader? I understand when it is purchased, Giztop and Wonda both update and add Google on the phone to save customers the pain of trying to start the phone in Chinese which in turn I understand the Bootloader is permanently locked. You could when ordering, tell them not to update and hopefully it is still with the original rom that is unlockable, but not sure.

The Japanese instructions for unlocking the bootloader, rooting with Magisk, and installing the VoLTE enabler module are dated June 26th. If find that date odd. For these instructions to work you would need to have a pre-June version of the firmware, because the June 1st security update removed the unlocking vulnerability that this method relies on. Vivo hasn't added any firmware versions for the Vivo X Note or the Vivo X Fold to its downgrading tool, so if you upgraded (like I did) before using this exploit you are out of luck. The reason I ordered the Xiaomi Mix Fold 2 is that unlike Vivo, Xiaomi allows you to unlock the bootloader, so I will root with Magisk (canary) and install the VoLTE enabler module the Japanese chap used.

ur right, the guy wrote at the top of the page (in red) saying that the latest version of OS is blocked from unlocking the bootloader.... maybe i shouldn't update my OS....

    I am still waiting as well. The updates are released in batches by IMIE number, so you should get it in the next few weeks. Unfortunately the updates download and install without the option to simply download first. Consequently, I can't see anyone having the update file available to share because it is not stored on the device once the update has been applied. The publicly available firmware on the manufacturer's Chinese site is still several versions behind.

    Ohh wow!! I'm wanting to get the vivo x fold but soo not sure it would not work in the US. I'm currently with ATT and they have done away with the 3g voice which sucks..but with the new update to enable VoLTE it should work I would think. I currently have the Samsung note 20 ultra which I had to get due to the 3g voice discontinued from my Huawei mate 20.. I love that phone lol...
    I used my phone in New York on T Mobile (roaming) without any issues I was getting 5G

    Cool !! Does the dialer code work on all of Xiaomi phones and only Xiaomi phones!?.. what's the dialer code?
    Dial * # * # 86583 # * # *. After that, the message " VoLTE Carrier check was disabled " will appear, thus making the VoLTE option appear in Settings/Mobile Networks/SIM. Toggle on VoLTE and you are good to go. It only works on Xiaomi devices.

    a japanese figured out how to unlock volte in japan. but u have to unlock the bootloader, root and patch an img file with magisk. then again, it's a risk for doing that. and it might not necessarily work in canada.

    Got a new update and wifi calling has been switched on.....awesome newsView attachment 5702127
    GREAT news. I've been debating on getting the Xiaomi Mix Fold 2 or Vivo X Fold S (when it comes out). This adds a point to Vivo.

    (also commented on their Facebook page: https://www.facebook.com/vivocareGlobal a quick question also)

    I am in Canada interested in getting the Vivo X Fold, but finding out that Canadian carriers (main ones here in Canada: Rogers and Bell) from local XDA Forum on the Vivo X Fold (https://forum.xda-developers.com/f/vivo-x-fold.12651/) do not allow the VoLTE 4G to be turned on here in Canada even though carriers support 4G and LTE bands on your phone.

    VoLTE is the major Voice Over LTE 4G communications standard protocol, that allows us in Canada with local carriers to talk on the phone with others.

    See forum feedback from XDA member that is in Canada with your Vivo X Fold phone:
    https://forum.xda-developers.com/t/...e-fence-as-to-which-one.4473827/post-87216075
    for his feedback and efforts to get VoLTE to work, i.e. it is not working!

    Is there a reason why the VoLTE 4G is greyed out and can't be turned on, on the Vivo X Fold her in Canada, thereby making voice phone calls not possible on your phone through this standard voice communications protocol?

    There are a lot of interested people here for the Vivo X Fold in Canada that want a quality foldable phone and don't want to use the Samsung fold because it is too narrow on the front screen,
    but looks like we are forced to get it as it is the only foldable that will work on Canadian carriers! Your phone is the only other possible choice BUT DOESN'T HAVE VOLTE 4G WORKING with any of the carriers here in Canada!

    Have confirmed this with Rogers and Bell putting their current Sim Card in, and the option to turn on VoLTE is greyed out, i.e. can't be turned on by either cellular service.

    I know T-Mobile in USA, the Vivo X Fold works on their network, but why not at least one carrier in Canada?
    (There is talk that Vivo got their phones certified for use with T-Mobile in the USA, but no carriers were certified (paid registration fee so that it works with carrier) in Canada, leaving us Canadians that want to use any of your phones, not able to because the VoLTE can't be turned on in the phones mobile service settings.

    Can you tell me why this is not working and/or reason why VoLTE is not able to be turned on?

    Is there anything that can be done about this?

    For what its worth, you can enable VoNR for stand alone frequencies. in developer settings or with a dialing code. The problem is that while these phones can connect on n78 Stand Alone networks, (3500mhz) the Canadian telecoms have just started using this frequency and it is only in a few major cities. They are also not using Voice Over 5G (VoNR) so even when the n78 band reaches your area, you would have to wait for the carrier to switch their technology for voice calls from VoLTE to VoNR. So far only T-Mobile (in Seattle and Salt Lake City) have turned on VoNR.
