  • VoLTE and VoWiFi compatibility

    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 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 provider spusu.

    So, is there any way of knowing if any generic, no name sort of tablet
    may have working VoLTE on any particular provider? I.e. if I look and
    see what processor it has, or what Android build numberi, will that help
    me guess what mainstream tablet it might be very close to matching?

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

    There isn't AFAIK. VoLTE provisioning is a function of (device,firmware,network) - you can't really tell that in advance. If the first two are on the network's whitelist then the IMS can provision you with
    a VoLTE profile, but if something doesn't match then they won't.

    The best source of information is the network's list of supported devices,
    but they're not going to have no-name devices on there.

    So alternative Android OSes can force provisioning, or others can be patched but you may need root for that - and good luck trying to root a no-name
    device.

    It is.
