• VoLTE and VoWiFi compatibility

    From Chris Green@cl@isbd.net to comp.mobile.android on Wed Feb 11 20:48:18 2026
    From Newsgroup: comp.mobile.android

    This is suddenly becoming more impportant now that 3G is rapidly
    disappearing. My 'no name' tablet used to work fine at home but now
    it doesn't. We used to have good 3G coverage here, what we have now
    is mediocre 4G and my tablet can't do VoLTE with my provider anyway,

    Being a cheapskate and not being a big mobile/cell user I don't want
    to spend hundreds of pounds on a new device just to ba able to make
    phone calls. My -u99 10" tablet is excellent in every way except for
    its lack of VoLTE support on my (very cheap!) provider.

    So, is there any way of knowing if any generic, no name sort of tablet
    may have working VoLTE on any particular provider?

    It really is a rather messy can of worms isn't it?!

    At Amazon you find cheap 4G phones starting around -u40. Of course these
    are then only feature phones and not Android based devices. But for the specific need to be able to do phone calls, that should be sufficient.

    No, just the transition to a new technology.

    Without VoLTE these phones wouldn't work at all in modern networks,
    since GSM is switched off already in many countries and 4G/5G is the
    only option left.

    3G just worked or didn't. If you had a 3G phone (for the right region probably) it worked. You didn't have to look in a list of what
    providers supported which phones to see if it would work for you.

    Well, 3G was invented nearly 25 years ago.

    Mobile network providers can not keep old standards running forever, if
    they want to introduce newer technologies and re-use frequencies for
    newer standards.

    Now we have 4G and 5G and with a device which is 5 or 10 years old, you
    should expect issues like this. We don't live in a world any longer,
    were technical standards exist for 50 years or longer.

    It's similar to ISDN - this was also phased out in most countries and
    replaced by VoIP. The hardware needed for the infrastructure is just not produced any longer, similar to 3G.

    They wouldn't be called 4G phones if the couldn't do VoLTE.

    For VoWiFi though, I think you're right, they're unlikely to support it.

    What! That's surely not true. A 4G phone is one that can use 4G data,
    it **may** do VoLTE as well but that's a separate issue.

    For VoWiFi though, I think you're right, they're unlikely to support it.
    Some providers seem to equate the two as regards support, i.e. the
    list of supported VoLTE phones is the same list as the list of
    supported VoWifi phones.

    Exactly!!! They wont work. They'll access 4G data (what for?) and

    calls and SMS using 2G won't they?

    I didn't say they should. The issue is that 4G voice isn't a standard
    service like 3G voice was.

    Now we have 4G and 5G and with a device which is 5 or 10 years old, you should expect issues like this. We don't live in a world any longer,
    were technical standards exist for 50 years or longer.

    All irrelevant. Yes, old technology is discontinued but the new should
    work as well, if not better. The reality of VoLTE is that it works
    for some phones on some services and it's not all the same phones on
    all services. A buyer shoud be able to buy a 4G phone and expect it
    to work on 4G, except that he needs to know that 4G capability doesn't
    mean tha ability to make phone calls (a bit fundamental for a phone I
    would have thought!). Even if the buyer knows that VoLTE is needed
    then it's still pot luck, a phone that is VoLTE capable **may** work
    with a provider of VoLTE service but there's no certainty about it.

    Why should a phone which is *not* a smartphone do 4G data only?

    Example:

    Nokia 105 - of course it supports VoLTE and it is quite cheap as well.

    ... and it's not listed as supported by my provider, so will it work
    or not? The list of Nokia phones supported by my provider is as
    follows:-

    HMD Fusion
    HMD Skyline
    Nokia 215 4G
    Nokia G42

    ... and certainly neither of my 4G smartphones (which aren't listed as supported) can make calls. So, if the list of supported phones is to
    be believed the Nokia 105 wouldn't work with my provider.

    This is the whole issue, a phone may have VoLTE working with some
    providers but it's hit and miss which ones work with which providers.

    ?? "Supporting VoLTE is *required* in 4G". No it's not, that's the
    whole problem. There are lots and lots of phones out there (I have
    two) which support 4G but can't make calls using 4G. All that 4G is
    useful for on these phones is for data, i.e. internet browsing and such.

    "Without VoLTE you can not do phone calls at all in a 4G network", you
    said it! :-)

    All the 'simple 4G phones' that I can see on Amazon have 2G coverage
    as well so, almost certainly, that's how they make phone calls. I even
    found a review of one of them that said exactly that, although the
    phone claimed to be 4G it only actually worked for making phone calls
    using 2G.

    Yes, but one could go through a heck of a lot of wasted time buying and returning phones. Without any clear guidance as to which '4G' phones
    will actually be able to make phone calls it's a minefield.

    For a long time I had my phone set to 2G because it was the only
    reliable way to receive calls. O2 didn't allow wifi calling, purely as a
    matter of policy. Then they switched of 2G and 3G, but switched on Wifi calling. But I am paying for my Wifi, not O2. I am surely it all works
    out nicely for them.

    No. Supporting VoLTE is *required* in 4G and not an option. Without
    VoLTE you can not do phone calls at all in a 4G network.

    The problem is not 'support', it's 'provisioning'. VoLTE needs to be provisioned by the network in an IMS profile. If the network decides not to send the profile then VoLTE isn't activated. If the network hasn't
    whitelisted the phone model (which a no-name from China won't be) then no profile is sent and the phone doesn't active VoLTE. I've heard that
    different phone brands provision VoLTE in different ways[1] so how to
    provision isn't standardised (but I don't know the details).

    GrapheneOS recently added a toggle so you can force provisioning of VoLTE
    even if the network hasn't sent the profile. There may be hacks (requiring root) for other brands/OSes, I'm not sure what's out there. I'm unaware of
    a phone brand who provides a force-provisioning toggle in their standard OS.

    Then give the phone back if it does not work and get another one. You
    can send the phones back to Amazon if they don't work as expected.

    It's more difficult because you can't always tell if VoLTE is provisioned everywhere. There's an Android shortcode *#*#INFO#*#* you can dial which
    tells you if it is, but that may be specific to the towers at a given
    location and doesn't work on all phones.

    What! That's surely not true. A 4G phone is one that can use 4G data,
    it **may** do VoLTE as well but that's a separate issue.

    Why should a phone which is *not* a smartphone do 4G data only?

    Example:

    <https://www.hmd.com/en_int/nokia-105-4g-2021?sku=16VEGB11A01>

    Nokia 105 - of course it supports VoLTE and it is quite cheap as well.

    ... and it's not listed as supported by my provider, so will it work
    or not? The list of Nokia phones supported by my provider is as
    follows:-

    HMD Fusion
    HMD Skyline
    Nokia 215 4G
    Nokia G42

    ... and certainly neither of my 4G smartphones (which aren't listed as supported) can make calls. So, if the list of supported phones is to
    be believed the Nokia 105 wouldn't work with my provider.

    This is the whole issue, a phone may have VoLTE working with some
    providers but it's hit and miss which ones work with which providers.

    Excuse me, but in which third world country is this?

    As said, a 4G *phone* *must* do VoLTE and a mobile provider which uses
    4G with no 3G or 2G fallback for calls/SMS *must* provide VoLTE.

    Anyway, just pick a phone to your liking and then go to the
    manufacturer's website with the *detailed* product number - i.e. not
    just a 'name' - and look up the specs to see which technologies and
    bands it has. If it doesn't give this info, select another manufacturer
    which does.

    Now with a right selected phone, select a matching provider. If they
    don't 'support' your phone, while they say they use its technology and

    FYI, ever since the later 90s, I have *never* checked/asked my

    Yes, so **one** Nokia non-smart phone is supported and others aren't.
    This is the problem, other providers have different lists so, while
    the Nokia 215 4G is supported by my provider it most likely isnn't
    supported by other ones.

    I don't want a non-smart phone anyway. I'm just trying to point out
    that a phone which works with VoLTE on one provider may well not work
    with VoLTE on another provider. As I understand it there are several
    different ways to make VoLTE work and different phones and different
    providers use various ways to make VoLTE work. As a result phone A
    that works on provider A may well not work on provider B.

    Well it's simply not true here in the UK and, as far as I know through
    the whole of Europe.

    Well, I live in The Netherlands, and my *2016* Huawei Y5 phone, which
    I bought in Australia, did VoLTE perfectly fine when my provider
    (Vodafone) switched off 3G in 2020. And our newer 4G phones also do
    VoLTE.

    As several UK posters seem to indicate, this might be a UK problem.

    Anyway, just pick a phone to your liking and then go to the manufacturer's website with the *detailed* product number - i.e. not
    just a 'name' - and look up the specs to see which technologies and
    bands it has. If it doesn't give this info, select another manufacturer which does.

    Now with a right selected phone, select a matching provider. If they don't 'support' your phone, while they say they use its technology and bands, tell them to get a life and take your business elsewhere.

    Can any other UK posters comment on this 'support' nonsense?

    FYI, ever since the later 90s, I have *never* checked/asked my
    providers if they 'support' my mobile phones. Why on earth would I!?

    Exactly! However, as I say, I have two 4G capable devices neither of
    which can make phone calls now that 3G has gone. (2G has never had
    coverage here). I didn't expect to have to check but having found out
    that 4G doesn't mean a device can make calls I'm not aiming to be
    bitten again.

    You now talk about two devices, but I thought you initially mentioned
    only one, a tablet.

    So what *are* your "two 4G capable devices? Please give some details
    as to brand, model, year, etc..

    If they are both tablets, this might well be a tablet issue, because,
    as we said, a 4G *phone* *must* have VoLTE.

    Coming to think of it, is it possible that your "'no name' tablet",
    doesn't have the right 4G *frequency bands* and that it never actually
    used 4G, but now has to, as 3G is switched off?

    Especially cheap devices do not have all the bands which more
    expensive devices have and if it was a device for another geographic
    area it might not have the right bands. That's why I bought my Huawei Y5
    phone in Australia, so that it would have the correct bands for
    Australia and (most of) the EU.

    So when you're using your "'no name' tablet", does it actually say
    '4G' in the top of the display when you're using mobile data? Yes or no?

    (Vodafone) switched off 3G in 2020. And our newer 4G phones also do
    VoLTE.

    So you were lucky, that's fine! :-)

    As several UK posters seem to indicate, this might be a UK problem.

    Anyway, just pick a phone to your liking and then go to the manufacturer's website with the *detailed* product number - i.e. not
    just a 'name' - and look up the specs to see which technologies and
    bands it has. If it doesn't give this info, select another manufacturer which does.

    Now with a right selected phone, select a matching provider. If they don't 'support' your phone, while they say they use its technology and bands, tell them to get a life and take your business elsewhere.

    Can any other UK posters comment on this 'support' nonsense?

    FYI, ever since the later 90s, I have *never* checked/asked my providers if they 'support' my mobile phones. Why on earth would I!?

    Exactly! However, as I say, I have two 4G capable devices neither of
    which can make phone calls now that 3G has gone. (2G has never had
    coverage here). I didn't expect to have to check but having found out
    that 4G doesn't mean a device can make calls I'm not aiming to be
    bitten again.

    You now talk about two devices, but I thought you initially mentioned
    only one, a tablet.

    So what *are* your "two 4G capable devices? Please give some details
    as to brand, model, year, etc..

    If they are both tablets, this might well be a tablet issue, because,
    as we said, a 4G *phone* *must* have VoLTE.

    Coming to think of it, is it possible that your "'no name' tablet",
    doesn't have the right 4G *frequency bands* and that it never actually
    used 4G, but now has to, as 3G is switched off?

    It runs 4G data very well
    Especially cheap devices do not have all the bands which more
    expensive devices have and if it was a device for another geographic
    area it might not have the right bands. That's why I bought my Huawei Y5 phone in Australia, so that it would have the correct bands for
    Australia and (most of) the EU.

    So when you're using your "'no name' tablet", does it actually say
    '4G' in the top of the display when you're using mobile data? Yes or no?

    Yes, and so dows the phone.

    This is the whole issue, a phone may have VoLTE working with some providers but it's hit and miss which ones work with which providers.

    Excuse me, but in which third world country is this?

    As said, a 4G *phone* *must* do VoLTE and a mobile provider which uses
    4G with no 3G or 2G fallback for calls/SMS *must* provide VoLTE.

    Well it's simply not true here in the UK and, as far as I know through the whole of Europe.

    So did you follow my/our advice to pick a candidate phone, look up the

    'support' of said phone?

    After all, we don't have your kind of problems, so we can't do your

    Yes, for some time it was my only phone, but I bought a Pixel 8a a
    little before the local 2/3G was removed thus disabling the Samsung.

    My no-name tablet is perfectly capable of making phone calls on 2G and
    3G. I can also use 4G data.

    This is suddenly becoming more impportant now that 3G is rapidly
    disappearing. My 'no name' tablet used to work fine at home but
    now it doesn't. We used to have good 3G coverage here, what we
    have now is mediocre 4G and my tablet can't do VoLTE with my
    provider anyway,

    Being a cheapskate and not being a big mobile/cell user I don't
    want to spend hundreds of pounds on a new device just to ba able
    to make phone calls. My -u99 10" tablet is excellent in every way
    except for its lack of VoLTE support on my (very cheap!)
    provider.

    At Amazon you find cheap 4G phones starting around -u40. Of course
    these are then only feature phones and not Android based devices.
    But for the specific need to be able to do phone calls, that
    should be sufficient.

    ... and they almost certainly won't do VoLTE or VoWiFi will they?
    They certainly aren't listed as such by any of the providers I've
    looked at?

    Without VoLTE these phones wouldn't work at all in modern networks,
    since GSM is switched off already in many countries and 4G/5G is the
    only option left.

    Exactly!!! They wont work. They'll access 4G data (what for?) and
    that will be about it. Actually most of them will probably provide
    calls and SMS using 2G won't they?

    No. Supporting VoLTE is *required* in 4G and not an option. Without
    VoLTE you can not do phone calls at all in a 4G network.

    ?? "Supporting VoLTE is *required* in 4G". No it's not, that's the whole problem. There are lots and lots of phones out there (I have two) which support 4G but can't make calls using 4G. All that 4G is useful for on
    these phones is for data, i.e. internet browsing and such.

    "Without VoLTE you can not do phone calls at all in a 4G network", you
    said it! :-)

    All the 'simple 4G phones' that I can see on Amazon have 2G coverage as
    well so, almost certainly, that's how they make phone calls. I even
    found a review of one of them that said exactly that, although the phone claimed to be 4G it only actually worked for making phone calls using
    2G.


    [...]
    work as well, if not better. The reality of VoLTE is that it works
    for some phones on some services and it's not all the same phones on
    all services. A buyer shoud be able to buy a 4G phone and expect it
    to work on 4G, except that he needs to know that 4G capability
    doesn't mean tha ability to make phone calls (a bit fundamental for a
    phone I would have thought!). Even if the buyer knows that VoLTE is
    needed then it's still pot luck, a phone that is VoLTE capable
    **may** work with a provider of VoLTE service but there's no
    certainty about it.

    Then give the phone back if it does not work and get another one. You
    can send the phones back to Amazon if they don't work as expected.

    Yes, but one could go through a heck of a lot of wasted time buying and returning phones. Without any clear guidance as to which '4G' phones
    will actually be able to make phone calls it's a minefield.

    It's worse than that.

    I have a phone which provides VoLTE calling on Tesco (on the back of O2)
    but won't provide VoLTE on any other major carrier although it will
    provide 4G data (which I use for web surfineg etc. when away from home).

    I am told that Android 12 sorted most of this out with a rewrite of the
    stack, but I am stuck on Android 11.

    So for the moment the dual SIM phone is still usable with Tesco for calls,
    and a.n.other for data.
    However if I travel abroad, who knows what will happen.

    Cheers

    As posted up stream, my realme 6 Pro with dual SIM can work with Tesco
    (O2) using VoLTE but with no other UK provider.
    Running Android 11.

    If I swap the SIM cards into my Samsung Tab A8 tablet (Android 14) they
    all support VoLTE, so the carrier is providing the support for VoLTE.

    My particular phone is not supported by 3 of the 4 major UK carries for
    VoLTE despite being VoLTE capable.
