Hi all,
In Australia at least, the current crop of Sony Xperia phones such as the 1 ii and 5 ii have 5G bands compatible with our carriers however I've not read of a single person being able to actually connect to 5G.
I'm on SEA firmware.
My wife just purchased an ASUS Zenfone 7 Pro and 5G worked out of the box for her.
Both handsets are not sold in Australia but hers works?
Has anyone else had luck connecting to 5G?
Pretty annoying owning a 5G mobile, that has the required bands, being unable to connect to 5G.
Cheers
Does anyone know?
Check if your Service Provider supports bands which Xperia 5 II supports: 1, 3, 8, 28, 77, 78
Zenfone 7 Pro supports these bands: 1, 2, 3, 5, 7, 8, 12, 20, 28, 38, 77, 78.
So it could be your Service Provider supporting bands which are not supported by Xperia 5 II.
No, Optus uses bands that the Sony Xperia 5 ii should support.

Optus
Optus is Australia's second largest mobile network operator, providing high speed connectivity over its 3G, 4G, and 5G networks. Optus is currently making a significant push into regional and rural areas with its $1 billion regional Australian network investment program announced in 2018.

Optus 5G
5G caught a lot of people in the technology industry by surprise. Expectation was that we wouldn't see 5G implemented until 2020 at the very earliest. But the tech industry moves faster than any other and 5G is already here. The key Optus band for 5G is n78 (3500 MHz) which it has deployed with 64T64R Massive MIMO antennas. Optus' 60 MHz channel means it can pipe around an extra gigabit on top of its existing 4G LTE network.
3.5 GHz does have a limited range, but beamforming technology has been demonstrated to provide similar range to that of 2.6 GHz. With 5G there aren't a lot of options as far as traditional external antenna systems go, 5G is such an advanced technology that we can't use old fashioned coaxial cables and patch leads. All 5G units worth their weight are all-integrated ODU style.
In the next year or two we'll see the introduction of mmWave 5G on Optus, who are looking at n257 (26 GHz) as their main millimetre-wave band. This is where things will get very interesting, and incredibly fast with trials showing data rates as high as 70 Gbps. Picking a 5G integration partner who understands the technology is going to become more and more important as the industry progresses.
Optus moved very fast on 5G. Our expectation is that Optus 5G will continue over n78 (3500 MHz) for the time, but an eventual refarming of its extensive 2300 MHz holdings is a near-certainty. Optus secured 98 MHz of 2300 MHz spectrum when it acquired Vivid Wireless in 2012 and portions of the spectrum are currently used for B40 LTE for the company's 4G Home Broadband service. It's R-Spectrum's prediction that an 80 MHz n40 5G carrier will be implemented in the coming years - possibly making the Optus 5G network the fastest in Australia.
Optus officially launched 5G services in November 2019 with an initial 290 sites, and expanded to 1200 as of March 2020.

Looks like all bands you mentioned in above table are 4G(LTE) bands. For 5G only n78 is supported by your provider so check if your phone has support for this band. I believe you have XQ-AS72 model so check if you have this support and you are selecting correct network from Preferred Network.

Yes but the XQ-AS72 supports n78
Sounds like Sony doesn't have yet approved your Carrier so 5G is not enabled in your phone if you don't see 5G icon on status bar while you are connected to 5G tower. There is Carrier Policy could limit this.
Have the same issue here in the Philippines. As72 on A11, global version(?), Globe network. Should also be on n78.
No 5g, no volte, no wifi calling.
@homerlovesbeer I can confirm the latest firmware XQ-AS72_Customized SEA_58.1.A.1.178 doesn't have 5G enabled in Australia. There is no NR-NSA bands defined in band_set_01.xml file:

Thanks, @olkitu. I Appreciate the confirmation.
It's weird that there's an option for 5g Nr in the network type selection but no actual bands.

So if I'm on Optus can I enable VoLTE now? If so, how?
Also wouldn't Sony be in a bit of trouble saying the phone supports required 5G bands then doesn't implement the required software to use them?

Well still you can't connect 5G because no bands allowed use.

Somewhere in Android Settings should allow enable VoLTE? Yes the device support 5G bands as in specs says but these are not enabled on your network. Bit silly they don't publicly tell that but it's possible extract firmware and modems and look there. Also if you have rooted possible also modify and enable. I have made blog post how to edit policy files but this require root: https://mt.ax/Rt8Uh
Is Sony updating this modem configurations? Or is it given and future firmware updates won't change anything?

Just thought i should post this since i noticed a lot of people complain about LTE not working for them on their Mate 7 even though their network operator has LTE. Well the truth is that unlike 3G, LTE has two different modes. One called TDD/TD(Time Division Duplex) and another FDD (Frequency division duplex). What this means is that if your LTE network is on say the FDD mode, and your mate 7 supports TDD, even if your frequency is supported it wont work for you due to the fact that your mode isn't supported on the device. This happened to me and i did a research and found the reason. Though there are some devices that support dual mode LTE (meaning they support both the TDD and FDD) but unfortunately the AM7 doesn't. Especially not the one that shipped to Nigeria. Mine supports TDD but unfortunately the only 4G network available for use on mobile in my country (Smile network) is on the FDD.
Also check this blog for your network operator to see the band, mode and frequency it uses. Hope am allowed to post links but if not moderators should feel free to remove it. Thanks
http://www.huaweimobileshop.com/blog/4g-lte-frequencies/
Your information are a bit off. The Mate 7 distributed in Nigeria supports both the FDD and TDD LTE. It just does not support the band that Smile is using which is FDD 800MHz or Band 20. It supports the TDD 2300MHz (Band 40) supported by both Spectranet and Swift Networks in Lagos. iPhone 6 supports both bands 20 and 40 in Nigeria. I think the people in Huawei in Nigeria miscalculated since only Swift and Spectranet are available in Lagos, the commercial capital of Nigeria.
These are the bands supported by the Mate 7 sold in Nigeria. FDD-LTE 1800 / 2100 / 2600 and TDD-LTE 1900 / 2300 / 2500 / 2600 (Bands 1, 3, 7, 38, 39, 40, 41).
TL;DR at the bottom..
Hello,
So I have had the OnePlus one for just over 3 months now, and I'm currently running 100% stock OxygenOS (even thought that doesn't change the outcome of the question)..
Here in Australia we like to make things so much more confusing than they actually are, and this is truly the case when it comes to mobile phone network names. We currently have 2G, NextG, 3G, "4G" (HSPDA), 4G LTE, 4GX LTE, 4G Plus LTE, 4G+ LTE, and this makes things incredibly confusing when trying to work out if your phone is compatible with a service plan. Currently, I am with "Amaysim", who offered "4G" (HSPDA) plans only, until 3-ish weeks ago when they changed all their plans to 4G. I have already upgraded my line to 4G (free of charge), but Amaysim uses Optus' cell towers. Optus offers 2G, 3G, 4G (HSPDA), 4G LTE and 4G Plus LTE, my phone is working on everything but the latter two (as I don't get the chance to see if they are working till the 1st of May).
Now that we have the backstory out of the way, my question is, will my phone work with the 4G Plus network. From Optus' site:
OPTUS 4G PLUS NETWORK SPECTRUM FREQUENCY COMPATIBILITY
The frequencies we use on our 4G plus network to deliver superfast 4G include LTE 700MHz, LTE 1800MHz, 2100MHz, 2300MHz, and 2600MHz. Depending on your device compatibility, you can access some, or all, of the 4G Plus network. We're using the 700MHz spectrum to expand our network nationally, so If you want to future-proof your device, choose one with the "4G in more places" symbol to access our 4G Plus network wherever it expands. You'll be able to enjoy faster downloads and Internet browsing in loads of new places.
So while I will have LTE as the OnePlus One Supports LTE band 1(2100), 3(1800), 4(1700/2100), 7(2600), 17(700), 38(2600), 40(2300), Optus advertises elsewhere; If your device supports 700MHz/Band 28 – it’s a 4G Plus device.. So while the OnePlus One does support 700mhz, Optus says it's band 28, while on the OPO 700mhz is band 17..
TL;DR: My network advertises that their "4G Plus" is on the 700mhz/band 28 frequency, but the OPO supports 700mhz/band 17 frequency. Is this the same thing, but because of North America to Australia differences or whatever it's different?
I checked the Wikipedia article for the technical specifications of the different bands. Link: http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
Band 28 uses wider spectrum range for transmitting data. Band 17 uplink is from 704 to 716 MHz and downlink is 734 to 746 MHz, whereas band 28 is 703 to 748 and 758 to 803 respectively. Band 28 has wider range of channel bandwidths (3, 5, 10, 15, 20 versus 5, 10). Duplex spacing is also different (30 MHz on Band 17, 55 on Band 28).
In theory my conclusion is that it will not work.

Hmmm alrighty. Cheers, I guess if I decide that I really do need 4G "Plus" that I will unlock band 28 using the band unlocker guide.
Thanks!
I rushed to buy this phone and bought it from Amazon where they said the phone shipped from Hong Kong. I am in the USA and use AT&T. Unfortunately I don't get any 5G signal, even though it's included in my service and the SIM card is 5G capable along with the IMEI being registered with AT&T. Besides 5G not working, the 4G coverage is super slow and I was thinking it was probably because the phone itself doesn't cover sufficient bands available in the USA because my last ROG Phone 2 was super fast in every way. Does anyone know how to unlock the bands for 5G or at least more 4G LTE bands please?!? I really can't stand these speeds
Your carrier would have to add them to the service. The bands you have are set by the hardware. You can't unlock them.
it is tied to your hardware. Youre screwed.. but please dont tell me you paid the premium on the phone just because its was on amazon? You could have gotten the same glorified tablet for 600-700 elsewhere

Who is going to buy it? Now that the proper local versions have released, the resale on a used foreign version is going to be about $200 (unless you pay shipping back to the origin country), meaning you are still around $800 short of buying the same phone.

Yesterday I noticed I had 5g service on my 16gb 256 version. I am also with att. I was surprised to see the icon so I checked the band. It was on band 2 which was previously a lte band in my area. The speeds were the same so I dunnno if it's really 5g or not. Mine is the global one direct from Asus

The global version from Asus has similar bands to the US version. The ones from Hong Kong are Tencent devices, which do not.

Interesting. I'm on AT&T with a 5g plan and sim, and I have yet to see the 5g icon. After spending some time with AT&T support verifying my IMEI etc, I still have had no luck and 5g is definitely active in my area. I have also purchased the phone direct from the US Asus store.
Do you mind sharing your APN settings?

Thanks for these. I'm going to try adding the settings that you used under bearer and see if it changes anything on my phone. I won't be able to try until later but will let you know.
The samsung devices list GID under MVNO and 53FF under value but if I do that on my phone the APN vanishes.
Hopefully Bmayne responds with their setup too since I have the same device.
Billy, thanks for asking about the APN. I didn't think to look at that. Apparently it's a new APN I haven't seen before. Here it is.

I could really use some help and advice on a subject I've spent countless hours trying to research. I live in the US and just bought the S22 Ultra without fully understanding what I now know, that the Call Recording feature - which I must have - is entirely disabled on the native "U" and "U1" variants sold in the US.
Why Samsung does this when recording is predominantly legal in most states is beyond me. And why someone hasn't yet figured out how to hack the software to turn it on everywhere is a shame, but this is where we are now, and so I am trying to find a practical workaround.
I have been using Skvalex Call Recorder for years on other phones with mediocre results because of its inability to properly record the audio from the other side of the call with the microphone, so when I heard that this Samsung phone allowed native, actual call recording, I jumped at the chance to get my new S22 Ultra.
Boy was I wrong, because that's when I realized that the CR feature is enabled in only a handful of countries, not the US, and that the only solution short of rooting the phone is to change the CSC code Samsung uses to identify which country-based phones are permitted to use the CR feature.
Okay, I thought, that's a great solution, but boy was I wrong again!
Well, that sounded easy enough until I learned that you can only change the CSC code on a phone designated for the same region as the country, in this case either the "B" variant (for Ukraine) or the "E" variant (for India and all the remaining CR-permitted countries), but definitely not the "U" version I now own.
It quickly became clear that no US phone can ever have CR without rooting, and beyond the complicated process of rooting an S22 Ultra for most, not only does that step void your warranty and completely disable the Samsung Knox functionality which breaks many apps, it also disables all future OTA updates, and you lose most of the trade-in value after Samsung charges you hundreds of dollars for a new motherboard once the Knox fuse chip is tripped. So, rooting is really not a great option for the normal user who wants to trade in every year or two, and doesn't want to hassle with having to manually apply updates every month.
Okay, I said to myself, the only other alternative is to bite the bullet and buy one of the "B" or "E" variants from overseas and then change the CSC ode, which sounded like a perfect solution (setting aside the need to buy another phone) until I discovered that the US and International versions of the phone actually have slightly different specs, and this is where it all comes down to - and I really need some help with this! - whether the International version will even properly work in the US at all.
Well, I'm sure at least the "E" version with the same Snapdragon chipset as the US version will work, but the question is will it work well, will it work as well as the US version for everyday use, not for someone merely traveling to the US and is happy just making a connection??? What will I lose in either speed or connectivity on the AT&T network?
The issue seems to be that the two variants operate on slightly different bands, as you can see below. There is a fairly large amount of overlap between the two sets of bands, but from what I can tell the main difference that could/would affect performance is the lack of any 5G mmWave connectivity on the International variant.
Now, I have zero knowledge about most of this, and from what I can read in most cases mmWave is not all that useful, but again, the issue is whether getting call recording on my phone is worth the trade-off of not having the most complete set of available bands on my phone?
If I could ask you good folks to give me your best advice as to what is else is actually missing from the list below on the International specs that would affect everyday performance?
ANY HELP WITH THIS WOULD BE GREATLY APPRECIATED!!!

I'm no telco expert & not in the US, but I think you should be largely good with the E variant on 4G/LTE. If you need 5G, you may need to choose a provider who provides the widest assortment of bands. Moreover it seems the E variant supports far more bands than the US variant. You may check here:

If for some reason you are not satisfied, you may sell off the phone on Swappa etc. There are plenty of buyers interested in international variants as well.
I've traded in 2 rooted phones in the past and both recd full trade in value, $800 with no issues. However I do agree with your main point that it sucks that the US variants are absent call recording.
Just use Skvalex. It records fine on my unlocked NA s22u on AT&T. Even records wifi calls and VOLTE calls. Only one side on Bluetooth though.

There arent any call recorders in the play store that work correctly due to new Google policies. You will have side load it.

what's wrong with installing a 3rd party recording app?
Callapp Contact record perfectly on USA or unlocked s22 ultra
Been here about 5 years at XDA, mostly just a lurker from time to time. I found it very interesting about enabling additional base for the US bands S22.
I bought the UK version at launch, wanted the dual SIM and eSIM as well, as I travel often around Asia and previous dual SIM models were extremely handy.
Here in Japan, 5G is very strong, hitting 900+Mbps when I hit a band that my phone supports, however the bands allocated for 5G in Japan are the 3.7 GHz band (n77, n78), the 4.5 GHz band (n79), and the 28 GHz band (n257). n77, n78, n79 and n257 (NTT Docomo).
The UK model supports 1, 2, 3, 5, 7, 8, 12, 20, 25, 28, 38, 40, 41, 66, 75, 77, 78- so I am missing the n79, and n257 which has the best coverage here in Japan.
I would appreciate any feedback you may have, I have tried the US model instructions in the other posts, however I can't get into that service menu dialing the short code.
Many thank in advance. Wes
I'm on S9080 and would love to know as well...
