Question SM-S9180 5G in the US - Samsung Galaxy S23 Ultra

I'm getting 5G Connectivity with T-Mobile in the US. My device has Taiwan (BRI) Firmware. Previously my S21 Ultra with Hong Kong (TGY) wouldn't connect. Anyone using an SM-S9180 Variant with TGY Firmware getting 5G on any carrier in the US? I'm considering flashing TGY Firmware and need assurance.

As far as I know, operators in the US use different bands in different areas so connecting to all of them from a device not adapted to the US, is a lottery.

That's been my experience as well.
SM-S9180 5G Band Capabilities
1 2 3 5 7 8 12 20 25 28 38 40 41 66 75 77 78
TMobile Broadcast Frequencies
Band n71 (600 MHz) Extended Range
TMobile UC 5G
Band n41 (2.5 GHz)
Band n258 (24 GHz)
Band n260 (39 GHz)
Band n261 (28 GHz)
41 looks to be the single match however the Anchor Band needs to match as well. Might be best to stand pat and be thankful it's available.

[Q] The EXACT bands of Nexus 9 LTE

I searched many times of websites on the lte bands of nexus 9 lte, but no, I've not got an exact spec of the lte bands that Nexus 9 LTE supports.
Until now I've got details of it from ht##tp://ww##w.bh##photovideo.c##om/c/product/1087410-REG/htc_99hzj002_00_nexus_9_volantis_32gb.html which the bands are
2.5G (EDGE, GSM/GPRS) MHz:850, 900, 1800, 1900
3.5G (HSPA+, UMTS/WCDMA) MHz:850, 900, 1700, 1900, 2100
3.5G (CDMA2000, EV-DO) MHz:850, 1900
4G (LTE) Bands:1, 2, 3, 4, 5, 7, 12, 13, 17, 19, 25, 26, 41

Now I'm sure whether this is right, are they the exact bands of Nexus 9 LTE?
I've got a Nexus 9 LTE from US to China, all three carriers have deployed either TDD-LTE or FDD-LTE, so I'm wondering whether I can use the LTE network with Nexus 9 LTE in China.
According to the specs above, it seems that it would work at TDD-LTE band 41 which China Mobile supplies, but I only got an EDGE with the 4G-SIM card inserted.
However China Unicom gives FDD-LTE band 3 network and China Telecom gives FDD-LTE band 1 network. Only lack of experiments.
The supported bands might be different depending on where the device is bought.
From the HTC site: http://www.htc.com/us/tablets/nexus-9/
Network (see note below)
2G/2.5G - GSM/GPRS/EDGE:
850/900/1800/1900 MHz
3G - WCDMA:
850/900/AWS/1900/2100 MHz with HSPA+ up to 42 Mbps
4G - LTE:
Bands 1,2,3,4,5,7,8,20
NOTE: Network bands in regions may be different, depending on the mobile operator and your location. 4G LTE only available in select countries. Upload and download speeds also depend on the mobile operator.
Built-in memory and connectivity vary by model. Wi-Fi only Nexus 9 features 16GB memory, and LTE Nexus 9 model features 32GB. Please see your local carrier for complete details.
data point for you: i have t-mobile spec nexus 9 bought in us. in hong kong a csl sim shows lte data status. speedtest showed 20mbit up and 20mbit down so i think its working fine. csl web site said bands 3 and 7 iirc.
csl web site: https://www.hkcsl.com/en/index.html
I actually clicked more than one website to bring you this info.

Looks like it's back in stock at store.htc.com for $359 for the LTE.
http://store.htc.com/store?Action=C...104_G - US - NAM - HTC - PS - Tablet - B&Ps=1
So from my Internet searching, here are the differences between the Nexus 9 LTE International vs. the USA device.
Nexus 9 Part# 0P82200 (EU/ASIA) handles LTE bands 1,2,3 ,4,5,7,8, 20
Nexus 9 Part# 0P82300 (US) handlesLTE bands 2, 4, 5, 7, 12, 13, 17, 25, 26, 41
What does this mean to us in the USA?
It means that if you buy the USA Nexus 9 then you're good to go for all USA major carriers.
But if you buy the International Nexus 9, then you're hurting yourself as follows:
Verizon missing band 13 (which it uses for most of its LTE).
AT&T missing band 17.
T-Mobile missing band 12.
Sprint missing all LTE bands.
US Cellular missing band 12.
Here is a list of what USA carriers use which bands:
http://www.droid-life.com/2015/02/0...sm-cdma-wcdma-lte-verizon-att-sprint-tmobile/
Oddly enough, the HTC USA website indicates that the Nexus 9 LTE it sells is capable of only the International bands listed above.
So I called HTC @ 866 449 8358 on 12/26/2015 @ 12:30PM CST and spoke with "Daniel" who advised that if I'm in the USA and purchase from the USA HTC website, then I will be shipped the USA version of this tablet.

BUY Oneplus 2 $459 64 GB from Oppomart - Works Tmobile LTE

After seeing it one oppomart for 459, i found 3 listings on ebay for $435 16 GB or $459 64 GB from oppomart that ship from china. i just ordered mine. I also chatted with tmobile, and they said the phone will support tmobile lte and hspa+ bands.
16 GB:
Mod edit: Links Removed
64 GB:
Yeah, just realized that. I canceled it and reorder from oppomart for $459 for the 64 GB black edition
Ordered the 64 GB from oppomart with a glass protector. shipping was $30 for 7 days, so total with everything was $496!
U do know there 16gb and only 3gb ram
Yeah, just realized that. I canceled it and reorder from oppomart for $459 for the 64 GB black edition
Yup I ordered mine yesterday
Comes with crappy Hydrogen OS though, doesn't it? You might end up waiting weeks or even months before someone gets a US OnePlus 2 and creates a flashable Oxygen ROM from it, so why not just wait to get an invite and save some money in the process?

It does not work on tmobile LTE. It will work on 2g and 3g.
Who knows for sure? Is Oppomart shipping the international version
with OxygenOs 2 and LTE compatibility?

yeah it won't work on T-Mobile LTE, their bands are 4 and 12, the oppo opt LTE bands are 1,3,7 (china version.
there seems to be a USA version of opt which supports bands: 1/2/4/5/7/8/12/17
There seems to be 3 versions (that I have seen so far), China, USA, and rest of world.
however it still needs to be confirmed if the hardware is the same between all versions, like the opo and just needs a utility to unlock additional bands.
Problem solved!!! I got this official answer from OppoMart suppport team:
"hello,
yes, the phone from us comes with oxygen os 2.0 and google play store installed,
and support GSM: 850/900/1800/1900MHz , WCDMA: Bands: 850/900/1900/2100MHz,
LTE FDD: Bands: 2100/1800/2600MHz., which can be used in your country.
Please feel free to contact us if you have any question.
Thank you and regards.

NO it is not the international version, it is the china version. Which only supports three FDD LTE bands 1,3,7
Band 1: 2100MHz
Band 3: 1800MHz
Band 7: 2600MHz
That's just a china version with Oxygen OS installed. You will still not be able to use it on LTE in USA.
My guess is they get china versions, open them up and install Oxygen OS and then sell them.
btw there is a difference between the version sold in USA and Europe as well.
I got better price for this product, pm me if you want to get it cheaper, with free shipping...thanks.

What I gather is that even the Global OP2 does not support 4G in the USA on the major networks which mainly use band 2,4,12/17 (AT&T/TM)
OnePlus 2 Europe/Asia model supports the list of FDD-LTE and TDD-LTE bands:
1 (2100 MHz)
3 (1800 MHz)
5 (850 MHz)
7 (2600 MHz)
8 (900 MHz)
20 (800 MHz)
38 (TD 2600 MHz)
39 (TD 1900 MHz)
40 (TD 2300 MHz)
41 (TD 2500 MHz)
OnePlus 2 North American model supports the list of FDD-LTE bands:
1 (2100 MHz)
2 (1900 MHz)
4 (1700 MHz AWS)
5 (850 MHz)
7 (2600 MHz)
8 (900 MHz)
12 / 17 (700 MHz)
Hopefully they all are hardware identical and a sodtware fix can unlock all bands

kudos for finding the time to put list up all the different supported bands. hopefully its the same situation as the OPO and we can unlock the other bands.
We went through this last year with oneplus putting people off buying a Chinese version, all sorts of discussions went on about separate hardware on different production lines, in the end the only difference was the rom and cyanogenmod logo.
I ordered mine from China last year and its still going great , and i´ve just ordered my two from oppmart.

What is Le Max 2's LTE A category?

Anandtech mentions it is LTE-A Category 12 (600 Mbps)
Some sites mention it is Category 6 (300 Mbps)
So what is it exactly?
With the new Non-HLOS.bin shipped with 17 S, there ist no cat 6 LTE , only 150 Mbit cat 4. The + sign at 4G sign doesnt appear
So should I go back to Indian 16S ? I am aware Indian 17S or 18S is on the verge of getting officially released. I prefer the Chinese 17S because battery is absolutely brilliant after removing the bloat. Indian 16S has horrible battery and standby time.
How to check the LTE-A ? I'm on CN 16s, in Malaysia (CA Band_3_7).
Whenever my phone show 4G+, then phone signal will drop for total no signal, can't call or data (Searching mode)

CN 16s and older ROMS are worthless for LTE. Try with Indian 16S.

If you get a chance please post your modem version. Thanks.
Snapdragon 820 has X12 modem (category 12 LTE up to 600 Mbps). I have had 4G+ for ages (in Japan on OCN Mobile One, an MNVO on the docomo network). However, as it is an oversubscribed MNVO my speeds are never great and even when getting a CA (4G+) signal they don't really change. My current firmware baseband version is as per this screenshot:

Unfortunately even on the same base chipset some of the radio params are up to the OEM, depending on what band combinations LE have programmed CA may work with some networks and not with others (eg OCN might be using 20Mhz x2 in 800Mhz while ThreeUK might be using 1x 15Mhz on 1800Mhz and 1x 15Mhz in 800Mhz).

Yes, obviously availability of CA depends on carriers and on the LTE bands available to the device. Not all bands are turned on for our device so some people some places are going to be SOL. In the case of OCN the carrier aggregation is probably working with bands 1 & 3 I guess (the other bands OCN use are 19 & 21, which are not available on the LeMax 2).

Ok so far then:
272-05 Three Ireland B3, B20, B8 Not Working
272-01 Vodafone Ireland B3, B20, B8 Not Working
440-10 OCN Japan (NTT) B1, B3, B19, B21 Working
Probably should just google what bands CN Mobile use for CA, that'll be the only thing LeEco will bother to implement in the baseband.

CA is strange. My friend has a Moto Z Play he bought direct from Motorola Japan. He is using OCN, same as me. His Z Play has the same available OCN LTE bands as my LeMax 2 (B1 & B3) and Motorola say it is CA compatible, but while I get 4G+, he doesn't. And another friend has a Japanese version ASUS Zenfone 3 and he gets 4G+ on another MNVO using same docomo network with B1 & B3. So it seems to be a bit of a lottery depending on your device & your region & carrier.

Compatibility isnt straightforward as its also dependent on resource blocks or RBs. Some radios can handle CA 2x 2x20Mhz and some might only manage 2x 2x10Mhz. Thats why reading the RRC messages between tower and handset is useful as OEMs dont release the full config that their UEs broadcast.
Snapdragon 820 aggregates 3 frequencies (3CC). I never managed to force him to do it, but 2 can (2ca).

Question add 5G frequency band?

hi. i live in canada and just switched to a carrier that supports 5G. problem is that this phone only supports 2 of the 4 frequency bands in this country. carrier's website says it supports 5G in my area and it's not picking up.
is it possible to add the other 2 frequencies?
i'm NOT rooted.
Not sure about your situation, but Sony isn't supporting all the advertised 5G bands.
My phone is using LTE 66 + NR 71 to light up the "5G" indicator. NR 71 is a low bandwidth, long range band meant to fill coverage gaps on standalone 5G phones. Standalone is disabled for NR 71 in the Xperia 1 III so it's a nonsense aggregation only for show.

Question European S23U in US

Now when European S23 Ultra is using Snapdragon - will it provide better 5G connection capabilities in US - especially on TMobile network? Or is it still locked to the same (limited) bands as Exynos S22?
thanks
It's SM-S918B or SM-S918B/DS right?
It would partially get 5G specifically for TMo where areas have n41 (2500)
Only the SM-S918U or U1 has the mmWave antennas
These are what T-Mobile uses for 5G
n260 mmWave (39GHz)
n258 (24 GHz)
n261 mmWave (28GHz)
n71 (600)
n41 (2500)
SM-S918B/DS.
Ok - so it looks like it will not be better in US than S22 Ultra Exynos.
