• Messages from iD Mobile about 3G switch off

    From David@wibble@btinternet.com to uk.telecom.mobile on Mon Nov 24 18:09:59 2025
    From Newsgroup: uk.telecom.mobile

    I have started getting messages from iD Mobile about the end of 3G
    coverage.

    Saying that I have recently being using 3G services.

    I use the iD Mobile SIM for data and a back up ability to make calls.
    My main phone number is on a Tesco SIM.
    Dual SIM phone.

    The phone is 4G capable.
    It has Wi-Fi calling enabled on both SIMs.

    Phone is realme 6 Pro.

    Am I likely to have issues, or is this just because I may have moved out
    of 4G coverage and fallen back to 3G?

    Cheers

    Does it do VoLTE for iD Mobile?

    Strange. IDNet runs on the old 3 network and I thought they had killed
    that off earlier this year? If there is no 3 then 4G should fall back
    to 2G for speech and texts - as indeed many phones do especially if they
    do not do VoLTE.

    I think Three don't have any 2G fallback any more, do they? Their network
    has only ever had 3G and up. Presumably ID is the same? In which case 'the end of 3G' likely also means the end of calls for 4G phones which don't
    support VoLTE.

    Er, given that 3 and VF are now one, would it be unreasonable to think
    that they may fall back onto VF 2G - which AFAIK is not due to be
    switched off until 2030.

    I've looked in Settings and it does seem to be available on both SIMs. Interesting question - how could I test that it is using VoLTE?

    I think the mast sharing between VF and 3 only works on 4/5G. MOCN are the magic letters if you want to research further.

    This suggests that it is the 3 network being unhelpful.

    This now gives me the problem of finding a mobile network (apart from O2) which has a compatible 4G/VoLTE for my phone.

    Also how to prove this without having to buy and reject various SIMs.

    I could always buy a new phone, I suppose, but I like this one and it does support VoLTE.

    As mentioned elsewhere in the thread, my phone supports VoLTE with Tesco/
    O2.
    So it appears to be an incompatibility between my phone and the iDmobile/3 network.
    Android 11 is early for good VoLTE support as Android 12 had a major functionality upgrade (I read).
    So it looks like a new SIM on another network or a new phone.

    Just swapped the TalkMobile/Vodafone SIM from my tablet into the phone.
    No 4G calling on the phone.
    My Samsung Tab A8 shows VoLTE using the iDmobile SIM.
    So definitely a phone problem and not confined to the 3 network.

    Looking more and more like new phone time.

    Although I think you've already moved on in your diagnosis, to answer
    your question above, if you fire up the Network Cell Info Lite app and
    then attempt to make a voice call when on a 4G/LTE connection (showing
    on the 'Gauge' tab) you will either see if remain on that 4G connection
    else it will roll back to 3G/HDSPA (or worse) having failed to use VoLTE.

    Which is what currently happens on my O2 PAYG SIM (as I patiently await
    the alleged 'upgrade' to support VoLTE....)

    I have started getting messages from iD Mobile about the end of 3G

    Saying that I have recently being using 3G services.

    I use the iD Mobile SIM for data and a back up ability to make calls.
    My main phone number is on a Tesco SIM.
    Dual SIM phone.

    The phone is 4G capable.
    It has Wi-Fi calling enabled on both SIMs.

    Phone is realme 6 Pro.

    Am I likely to have issues, or is this just because I may have moved
    out of 4G coverage and fallen back to 3G?

    I'm on IDmobile also but haven't received these messages? Is this a
    regional thing or specific to your device?

    As mentioned elsewhere in the thread, my phone supports VoLTE with
    Tesco/ O2.
    So it appears to be an incompatibility between my phone and the
    iDmobile/3 network.
    Android 11 is early for good VoLTE support as Android 12 had a major
    functionality upgrade (I read).
    So it looks like a new SIM on another network or a new phone.


    Try swapping the SIMs between slots and/or making the iD Mobile SIM the default...

    May already have posted upstream.
    SIM works fine in Samsung tablet.
    SIM out of tablet shows same issues.

    Three and Vodafone networks both won't play ball.

    The way to tell for sure is to dial *#*#INFO#*#* and look for the 'VoLTE provisioned' for each SIM. That works even if you don't have suitable
    signal.

    Which is what currently happens on my O2 PAYG SIM (as I patiently await

    I'm getting VoLTE on my O2 Classic PAYG SIM (Pixel 7 Pro, GrapheneOS). GOS does now have a toggle to force VoLTE provisioning if the network doesn't
    want to, but I've not enabled that. So it looks like O2 have deployed it,

    I know iPhones arenrCOt popular with some, but you donrCOt get this sort of problem with them. Simply because they command such a large proportion of
    the market of profitable customers that the providers canrCOt afford not to support them.

    I'm just moving to using VOIP on my mobile which should circumvent

    I am now getting Wifi calling on my O2 Classic with my Galaxy A14. I did
    not before, although I used to get it with the same SIM card in my Moto.

    I detect it by a) Network Cell Info says "IWLAN", b) swipe down from the
    top right and the symbol appears, c) When about to make a phone call the
    sybol also appears in the green button.

    (The symbol is a telephone receiver with concentric arcs radiating from
    it.)

    I can force these symbols to appear if I put the phone into a tin.

    I read in an OfCom report the other day that the usage of data in the UK

    ThatrCOs not entirely correct. Many 10 Gbit switches will not support a 10
    Mbit device. In general you get backwards compatibility in technology when
    the cost of so doing is low.

    2G and 3G donrCOt use the radio spectrum as efficiently as 4/5G. Spectrum is scarce, so itrCOs not sensible to support the older technologies in the long term.

    ThatrCOs not entirely correct. Many 10 Gbit switches will not support a 10 Mbit device. In general you get backwards compatibility in technology when the cost of so doing is low.

    Indeed, the clock plumbing inside the ethernet chip is annoying when you
    have to support three speeds, let alone four or five.

    Also many 10G switches don't support 2.5G or 5G: they're more or less
    parallel stands of development (10G for serious servers, 2.5/5G for gaming PCs). If you plug them together it's quite possible they fall back to 1G.

    2G and 3G donrCOt use the radio spectrum as efficiently as 4/5G. Spectrum is scarce, so itrCOs not sensible to support the older technologies in the long term.

    For ethernet, chip area is a concern - not much point putting in logic to handle 10M when you could save money by not doing so. Life was made a lot easier in our FPGA designs when we just did 10G everywhere and could bin all the negotiation and multi-clock stuff.
