    On local experience in South Somerset (land of a surprising amount of Band 8 4G…) there’s an interesting habit of 4G falling back to 2G for calls on giffgaff, NOT 3G… last time I saw this was in Italy when roaming on Vodafone IT which was super rapid to switch from 2G >< 4G depending on phone call being made/received.

    Coincidence? Or O2 planning to go full crackpot and just use 2G instead of 4G VoLTE for giffgaff, PAYG, Tesco PAYG etc. when they FINALLY decide to close 3G?

    How terrible is Lyca? Heard bad stuff but 1p a month for 6 months will save my mum a few quid.

    Looks like the customer support might be a bit grim. But, on the back of that, can't hurt to try them as a second sim for a month, before porting a number in. Worst case, you cancel in the second month and you're down two pence :smiley:

    Which side of the city are you?

    O2 is very poor and a bit 'patchwork' here. The new unwound sites fare best, but B40 tops out around 20Mbps during the day and doesn't aggregate with any of the FDD bands that I've seen. Lots of B20 only sites still and I'm lucky to see much over 1Mbps from them (new or old), perhaps slightly more in very good signal. B1 is 5Mhz only on most sites, 10Mhz on the new poles. There's still a lot of 3G2100 as well, which must cause some interference when the next site is doing 10Mhz 4G on what is presumably the same frequency?

    VF is much better - it slows but nowhere close to as much. Hardly any 5G though, and when I've used it it's no better than B7 LTE. B7 itself is quite limited in deployment and a lot of the 5G sites don't have B7 added (would have thought this would be easy).

    Three have loads of new sites in the suburbs which are incredibly fast, and lots of approved planning applications which will hopefully be built this year. Very slow in the city centre.

    EE is always fast, but not much B20. I would say the best, as long as you get signal where you need it.

    PS - you don't need root to see the bands - a free app like Network Cell Info or similar will show you. The Cellmapper website has all the site locations and bands on each if you haven't seen it.

    Typically I'm around Penylan/Roath and the city centre. Had a friend with me on EE and his speeds were way better - 200mbit/sec basically everywhere, when I was struggling to load webpages in many places because it was so congested.

    Yes I'm aware of those apps (use netmonster myself) but it doesn't show 5G bands, only 2/3/4G. As far as I know you need a rooted phone to see the 5G bands on networksignalguru?

    The 5G I get on o2 is really saturated through the day - maybe 5mbit/sec if you are lucky. Then late at night 120mbit/sec+. Seems a bit mad to me to add 5G to sites but not also add other 4G frequencies while you are it (as you mention with VF).

    Annoyingly EE has the worst roaming offer now imo (especially non EU).

    Re 2G on Tesco, aren’t they currently rolling out VoLTE as we speak?

    In London I am sure O2 are testing turning 3G off. I am pushed into EDGE which is useless so I hope in time this will become 4G

    TESCO Mobile is only rolling it out for PAYM customers; as someone who tried their PAYG system recently I can confirm it (and the app) is archaic, am guessing it’s a slightly modified O2 PAYG platform.

    5G in the UK is all "Non Standalone Architecture" (NSA) which means your phone is constantly connected to 4G and generally when you use data the 5G 'speed' is used, and then dropped. So to see a 5G band you need to be transmitting or receiving.... some people download large files, others stream YouTube.

    Network Monitor app (on Android) will show connected 5G band and doesn't need rooting.

    The more I think about it, I'm not so sure anymore. I'll have to put a 5G capable sim into my android phone and check again.

    Can’t you dial *#0011# to show network information still?

    I think that's a Samsung only thing.

    I have a 5G phone, but 5G isn't available in my area. I use giffgaff and I'm not impressed. My phone fluctuates constantly between H+, 4G and 3G, it also shows 5G sometimes, but it's not. Internet can be tediously slow, strangely it's worst when my phone is showing a H+ signal. Some people claim O2 doesn't throttle giffgaff, I'm inclined not to believe them.

    O2 makes some curious decisions.

    https://www.cellmapper.net/map?MCC=234&MNC=10&type=LTE&latitude=51.52363329522538&longitude=-0.07986175499727394&zoom=18.12333333333333&showTowers=true&showIcons=true&showTowerLabels=true&clusterEnabled=true&tilesEnabled=true&showOrphans=false&showNoFrequencyOnly=false&showFrequencyOnly=false&showBandwidthOnly=false&DateFilterType=Last&showHex=false&showVerifiedOnly=false&showUnverifiedOnly=false&showLTECAOnly=false&showENDCOnly=false&showBand=0&showSectorColours=true&mapType=roadmap&darkMode=false

    This is a cell near Liverpool Street, band 20 only. Lots of band 40 and small cells around.

    Vodafone is the fastest here, 250Mbps+, they have 1, 7, 8 and 20. EE second fastest with 3 and 20, around 150Mbps. Three third with 1, 3 and 20, around 80Mbps.

    O2 in dead last with only 10Mbps at most. It does work even at peak times but I can't understand the strategy here. It's very strange.

    A propos of nothing and not that it's particularly relevant any longer, but did O2 ever properly implement text message delivery reports?

    I seem to remember you could do it by putting a short code before the body of the text (*0#?) but that they never had the facility to receive them automatically, as was the case with the other networks.

    Do any smartphones support sms delivery reports ? I read somewhere that SMS volumes had halved due to things like RCS, iMessage, WhatsApp.

    My Huawei does. There's a little subtitle when I send an SMS, that says 'Sent' and then changes (normally after a second or two) to 'Delivered'.

    In my experience recreational SMS is virtually dead, but 95% of my SMSs are 2FA related from banks etc.

    Our work phones are Samsung androids and they automatically do a delivery report for sent SMS (even when to an iPhone, so not using RCS).

    Useful, must be using the network services, but I wonder if this is part of Samsung's messenging app... hmm. I'll have to play with my OnePlus :)

    The SMS for banking is a nightmare, the US security group NIST, and the UK NCSC are recommending that Banks move to app notifications as SMS is far from secure :(

    Lloyds Banking group and RBS already offer this (when it works).

    That coincidentally ties in nicely with the thread I just opened! I for one will be very happy if at least financial institutions stop using SMS for 2FA.
