Ordered 7t through Amazon, have questions. - OnePlus 7T Questions & Answers

Hey guys I am getting my wife a 7t. I was going to get it from their official site but noticed that Amazon had the 7t with 256gb ROM for cheaper. I noticed in the reviews a few people were complaining its the Chinese model (HD1900) and that its not global version. Should I cancel my order and just get it from one plus' website or am I fine with the one coming from amazon?

Don't take my word only but I don't think there is a specific model for China. I believe there is only a global model, european model and indan model. And a T-Mobile model if you want to count that. So I would think you probably got the global model and should be good but let someone else come in here and confirm it

You should be fine, I have the same model. all I did was change the rom to the global rom because it does come with Hydrogen OS. And also it should work fine with US carriers, I tried T-mobile, Verizon and AT&T

I think the basic differences between various variants are the network frequency bands. The question is which bands are supported in your region. On the basis of that, you can choose the correct variant.

This.
HD1900 is missing bands 25, 30, 46, 66, 71.
25 is a superset of 2, currently used by Sprint and potentially by TMobile eventually.
30 is important for ATT.
66 is a superset of 4, used by all the main supported carriers, although generally you'll be fine with just band 4.
71 is TMobile's new lowband frequency.
Yes, the hd1900 would likely work fine with all the carriers, especially in urban areas. However, reception may be spottier (lack of lowband 71), or bandwidth may be lower (4 instead of 66, missing 30).
My guess is the hardware is the same, but there hasn't been much effort to figure out how to unlock the other bands.

Ah, I cannot confirm that whether the hardware is the same or not. But in other threads, people are saying that if you flash the roms of other regions you can unlock those bands. There are many tutorials out there on how to unlock all bandwidths. I'm giving some useful links. Read them. Maybe you can find what you're looking for.

Well i got it the 7t today and it works great with my carrier (Cricket but it shows AT&T in the menu). Im really impressed with it especially for paying less than $500, its a bit snappier than my s10+. It already had Oxygen 10.0.4 installed and I just flashed 10.0.7 global and it gave me an OTA for 10.0.9. Really nice phone!

UK version of HTC 10 Compatibility with US networks?

Hi
Quick question from a newbie. I am currently in the uk and would love to preorder the 10 but I can only get the UK version but I would like the US version. Are there any significant drawbacks? Would most likely use it on TMobile once I relocate to the US. I have seen earlier posts on frequencies and bands but I was hoping on a plain English response? Mostly interested in LTE of course. Thanks!
Gotta find out if the UK version of the phone supports US network bands/frequencies to see if it'll work properly with the network you're interested in. Software wise should be the same. The HTC UK site lists #WL SKU(America) under supported networks but it also says, "Network bands in regions may be different, depending on the mobile operator and your location."
I'm sure someone in here knows whether you only get support for one region based on where you order from or if you get support for all regions listed on the spec page. Unclear to me. US page only lists US bands though.
I dont think the EU/ASIA models have the US LTE bands.
Sent from my SM-G935T using XDA-Developers mobile app
Yes the main difference is the LTE bands. The US version has different bands to the UK version. Generally the UK uses band 8 for LTE, which the US version does not have. You would still be able to use the phone for texts, calls and even 3G access, but, you would not get LTE. Let us know, what service provider you are with, we can then see if the phone is comparable or not for you.
Hi
I don't have the phone yet obviously. I am on three UK now but once we relocate to the US I will most likely be signing up to TMobile. I thought some of the frequencies are the same? Different bands but frequency seems the same in the UK and US?
But to be honest after looking into it might be best to pick it up in the us for the warranty and the Uh Oh insurance.
Thanks for the replies. Hope this question helps someone else.
From what I can see, Three supports band 3 for LTE. Looking at the US speck phone it says the following: 4G LTE (up to 450Mbps), FDD: Bands 1, 2, 3, 4, 5, 7, 12, 13, 17, 20, 28, 29, 30, Support Cat 9 LTE, download up to 450 Mbps, upload up to 50 Mbps, so in theory it should work for you both here and in the US. I would double check with Three that their network is definitely band 3.
Thanks Stephen
At the same time of posting here I had also emailed HTC support and they came back to me with a brief statement that it will work as the phone supports 'multiple frequencies'. This was not a highly technical reply but at least now I have it writing!
Your answer certainly puts my mind at ease and I have gone ahead and preordered!
Strangely I had no option to choose 32 or 64GB storage though and they took payment immediately rather than wait till shipping time. Does this mean it's on the way already?
Thanks again. Will revisit this post in three months time I suppose and jet you guys know!
I've been wondering about this, too, and I think the UK HTC 10 is not fully compatible with AT&T or T-Mobile networks in the US. From Droid-Life, the bands needed are:
AT&T LTE bands 2, 4, 12, 17
T-Mobile LTE bands 2, 4, 12
From Clove, the bands supported are:
FDD B1, 3, 5, 7, 8, 12, 20, 28, 32; TDD B38, 40, 41
As you can see, the UK version is missing bands 2 and 4, which are used by both US GSM carriers, and also 17, which is used by AT&T.
I've been looking at this because the UK HTC 10 is about the same price as the US one, but it comes with HD earbuds. Unfortunately, it looks like it's incompatible.
EDIT:
I also found HTC's international HTC 10 page, and it spells it out pretty clearly in the Network specs that the EMEA version of the HTC 10 is missing many bands from the American version If anyone has information to the contrary that would be great...
I have the International HTC 10 (m10H) and its working on AT&T LTE band 17. I haven't seen it connected to band 2 or 4 yet.
I'm using a UK version on Tmobile and it works fine the network.
My signal stays on 4g and I've only dropped to HSPA once, which is fine with me. Aside from that, text, calls, etc all work without issue.
If you're after the headphones, they're pretty nice though they're a bit bass heavy for my taste. They sound good though and the noise isolation is surprisingly good.
Hi
probably you can use con T-mo, but you can not use in AT/T. The asian version doesn´t work in any 4G in the US

LG lacking frequency bands compared to other manufacturers

I haven't seen this mentioned before but has anyone noticed LG devices are severely lacking bands compared to other manufactures? LG seems to tailor the bands based on the carrier and country. This seems fine if you don't leave your home country much. However, if looking for a device that works equally well in multiple countries, LG should be avoided. At least that's the conclusion I came to based on specs and my international needs.
For example:
T-Mobile LG V30 (14 LTE Bands)
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 20(800), 28(700), 29(700), 40(2300), 41(2500), 66(1700/2100), 71
T-Mobile S8+ (19 LTE Bands)
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 66(1700/2100), 38(2600), 39(1900), 40(2300), 41(2500)
Sony Xperia XZ Premium (20 LTE Bands)
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 17(700), 19(800), 20(800), 26(850), 28(700), 29(700), 32(1500), 38(2600), 39(1900), 40(2300), 41(2500)
Currently the V30 would be the best option for T-Mobile only because it has band 71 but if traveling somewhere outside of USA, it seems like it would be the worst option. I'm probably going to pick up the Sony for this reason. and later on upgrade to something else with band 71 when T-Mobile has deployed it in more areas.
What do you think about the limited bands available on LG Devices? Do you think this will limit coverage or only LTE coverage? Why would LG do this, do they save money by not needing to do additional FCC tests?
T-Mobile has free text and data in over 140 countries. I would assume that any phone they release, especially flagships, will work in ALL these countries. Now, if you wanted an unlocked version to use with another carrier sim, then I could see why you might have an issue.
Based on https://en.wikipedia.org/wiki/List_of_LTE_networks it looks like the T-Mobile LG bands will cover just about every country. I only checked until Puerto Rico, but only 1 country before that didn't support any LG bands and that was Anguilla, a country I have never even heard of. Other than that, every other country had at least one carrier which supported the LG bands.

Yes, they work around the world but they don't have as many bands as other manufactuer's and they don't have all the bands available in other countries so it seems like coverage would be less. This isn't a T-Mobile issue, it's an LG issue. Take a look at any LG phone compared to any other phone on the same carrier and the LG model is always lacking bands. Sony seems to be quite the opposite where they have fewer versions of the phones with almost all bands.
I would definitely be putting in a local sim card in the destination country so this would be an issue, even if I wasn't, roaming coverage on your home carrier seems like it won't be as good as if you had a different manufacture's phone with more bands in the area your visiting.

Your best bet might be to wait until your next device to get a band 71 compatible device. Depending on where you live, you might not even see any band 71 coverage until your next phone anyway.
A good concern to bring up for those of us that travel and rely on T-Mobile's great international coverage. I'm looking to get the unlocked V30 myself and it seems to have an even lower number of bands compared to the T-Mobile version, at least from what I can see on B&H's pre-order site. My main overseas travel is to Pakistan and England and looking at the bands used in both countries, the LG V30 covers them. That being said, when I have traveled with my current Nexus 5 that has less bands, I haven't had too many issues. I expect overseas data to be slow unless I get a local SIM but I agree it would be nice to have more options.
From B&H:
LTE: 1, 2, 3, 4, 5, 7, 12, 13, 20, 25, 66

This isn't just an LG issue. I've had the same issue with phones from any other provider. It's all part of traveling. I've always had to look at what bands are available where I'm going from which carriers and which bands my phone covered and then choose a local carrier accordingly. If you're lucky, you might even get a choice of two carriers that post coverage maps so you get to make a completely informed decision. So not really an LG thing.
In the band selection menu on the T-mobile version and on the box it shows 1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,39,40,41,46,66,71

Correct but if LG phones do in fact have 5 or so less bands, you're going to have more issues than if you had a different manufacturer with more bands. Depends on where you go and what those carriers support of course.

Looks like nobody knows what bands the phone has.
LG website says:
B1, B2, B3, B4, B5, B7, B12, B20, B38, B39, B40, B41, B46, B66, B71 (Some are listed as roaming bands. Not sure if they would work with a local sim or not or what that means)
GSM Arena says:
B1, B2, B3, B4, B5, B7, B12, B20, B28, B29, B40, B41, B66, B71
T-Mobile website says:
LTE: 1, 2, 3, 4, 5, 7, 12, 20, 28, 29, 40, 41, 66, 71 (Same as GSM Arena)
Box and phone says:

Have you even looked to see if the bands missing from the version you want are even used where you would want to go? Have you looked to see what those bands are even used for/who they are used by? They may not even be relevant bands.

Yes I did. For example according tmobile, lg, and gsm arena, it's missing LTE Band 8 which is needed for Truemove H in Thailand I believe so without it, the phone will still work but I probably won't have as good coverage. Other devices have that band listed.

Yes, otherwise I wouldn't of mentioned. This is a general observation that would affect many other people going to many other places as well assuming the band info online is correct. It's not a necessity to have all the bands to use your phone on other carriers but the service won't be as good.

Right, but all those extra bands are enabled through the "hidden menu" options. Don't you think the "open market" US998 will also let you add more LTE bands?
the box is usually correct, its all the companies developers that disables the bands not needed for their networks. Which makes it difficult to get the specs right for all the different variants. Thats why they should just list all the bands off the box, then say in bold your carrier may be blocking some bands.

So in this case it's possible that T-Mobile \ LG are only listing some of the bands on their websites since the box and phone show otherwise? It's pretty sad when LG's and T-Mobile's sites don't even match. On LG's site they list some of the bands as "Roaming Bands" which could mean those bands only work in roaming mode? It's too bad they can't put out accurate complete information.

For instance, it's well known the South Korean carriers' LG phones REALLY support most of the U.S. carrier LTE bands, even though the specs websites and South Korean carrier websites say differently. Many people from U.S. order LG phones off eBay from South Korea because those models often have better specs (like the LG G6 had quad DAC and more internal storage than U.S. LG G6) or receive OS updates first.
But it's hard finding specific information about exactly which bands. I just know from word of mouth. Someone yesterday asked me exactly which U.S. LTE bands were supported on the South Korean LG G6 PLus (the LG G6 on steroids released MONTHS later in mid-2017, and which FINALLY had all the specs in one phone), and I can't find an definitive source to answer that question. (There's three carriers and some may have more bands than the others.) I'm giving them the answer from an XDA user for regular G6.

Note 10+ Exynos Variant

I have purchased Exynos Variants for a bunch of different Samsung phones over the years. the "F" variant, N975F will work on ATT and or TMobile with no issues. (or N975F/DS)
If you want to buy, I have used two different places to buy in the past - both offer the Note 10 now -
Clove UK
or EBAY
Clove is an excellent source, fast shipping - good customer service and the major sellers on EBAY are also very good. I have used "Never MSRP" and I have heard that there are several others that I have heard are very good and reliable.
Whatever you choose, good luck

Verizon is cdma and the exynos variants are usually gsm only (AT&T and T-Mobile).
I doubt you'll be able to find what you're looking for.
yeah if you wan't an international version they will always be GSM where some of the US still uses CDMA. so whatever you bought you would need to check it supports the signal on network you want to use it on. also using an international phone you generally need to use a SIM from the local market for a set amount of time, my UK unlocked Note 9 actually has a disclaimer on the box it needed 5 minutes of calls with a european SIM before it would accept an international one, so that is also something you will have to watch out for or you end up having to pay to get an international sim and a several minute call at international rates to unlock the device for a US SIM.
I also use dual sim (F/DS) varieties of Samsung phones, they generally work fine on ATT in the US but they do miss some bands, specifically band30 which means that sometimes I have low speed or no data at all. Also, you won't get VoLTE unless enabled by your carrier. It's a trade-off. Of course you also won't get 5G until there's a dual SIM 5G variant.

Verizon is ending CDMA support at end of this year. So it doesn't matter with Verizon anymore.
It should be noted that with Exynos F models, USA Carrier Aggregation does not work properly.
While the phone will function properly, it will not have the same network speeds as an equivalent USA model.
For example, I had in my possession a N960F and did a speed test next to a N920T (Note 5) and I was getting like 70-90Mbps down on the Note 5 and was only getting 15-30Mbps on the N960F in the exact same spots.
I've tested this many times and actually also with the N950F before that.
I'm only posting about this just to make people aware. I'm, sure there are some that will take the trade-off of slower speeds to gain the ability of root and development, but there are also some out there that prefer that their speeds not be gimped.
This has been discussed on many XDA threads in the Note 8, S9, Note 9, S10 forums for a couple of years now and can be duplicated exactly as mentioned.
If anyone has figured out a way to get proper USA CA on F model phones I'm one of the first that would love to hear about it.
I'm sure @iunlock would also.

Along with @DeeXii around the same time I had the F variant of the Note 8 along side my T-Mobile Note 8 and ran numerous tests.
TL;DR, in areas with a lot of cell towers (in the city etc...) you won't notice a big difference (IF) your within a strong range (close) from a tower. When this happens you're connected to a single strong frequency.
While travelling on the road with both devices at the time it was very apparent that the F model was not handing off well (tower to tower), while the TM variant as expected did just fine.
It is in my opinion that those who have claimed that CA works on international variants are being tricked by getting real good speeds due to being connected to a strong signal from a near by tower / area. It's convincing I know...
We're convinced unless proven otherwise that CA is an issue with the international Exynos variants, whether it's the F or Korean N models. Yes, I'm aware of some N models showing icons that may say otherwise, however, it is yet to be seen if the CA is truly working as most people who have the international variants, often don't have the US variants handy to be able to compare them side by side under different conditions.
Believe me... I want to see CA to work lol.... I really really do, because I'd rather have an Exynos variant 100% over a locked down US variant.
As I wait for my Note 10+ to arrive tomorrow, as excited as I am for a new device, since it can not be rooted there's still an uncertainty in the back of my mind that doesn't bring me much assurance that I'll be 100% sold rocking a non rooted phone due to my apps that require root, tweaks that I do etc...
Engineering leak, oh if you're out there please show yourself.... :silly:

That's not accurate at all.
The Galaxy S10+ F model did 100% work with at least 2 bands carrier aggregation when used on T-Mobile and AT&T. Bands 4+2 on T-Mobile and 12/17+2 on At&t were aggregated. SOME models that were running a European CSC code from European countries did NO indeed have CA enabled in the US. Phones with Asias CSC codes had 2 band CA enabled in the US. It never supported more other bands CA in the US.
I experimented with this myself by flashing the main OXM ROM and then using a local country SIM immediately after flashing to change the CSC code of the firmware to one that SIM region. Every time it was a European CSC, CA would not longer work.
It's important to note that Wifi calling and VOLTE both worked on T-Mobile with the F model out of the box. This started with the S10 and i expect the same to be with the note 10.

Excellent. Please provide us some more info then showing your claims.
What I have stated is indeed accurate as it was based on my own tests with the Note 8 lol...many have done the same as well. This issue regarding CA has been hashed to pieces in several threads with a lot of folks involved in showing concrete proof that it did not work with the phones we've tested it with at the time.
Show us with screen shots, detailed description where the phones were tested etc... that CA works on the F variant and we'll throw a party....
You have to remember that there are several of us that really want CA to work... it's not like we're against it.
Again, we've seen this claim before and it was due to the user not factoring in that they were in a "good signal area near a tower," where they were connected to a strong signal that made it seem like CA was working in respect to the bands the international phone supported... I'm not saying this is the case with what you have experienced, but until we can see proof.... with this situation it's all heresay unless proven otherwise... therefore...
What you've said is not accurate at all, because we have no proof... so please provide proof.
@DeeXii I'll tag you as I'm sure you're just as curious...
Looking forward to hearing back... :highfive:
Well, just received the N975FD Dual SIM model and i'm testing it with AT&T and Project FI in the US (which uses T-Mobile).
This unit rung the Singapore firmware. As i stated in my last reply, Carrier aggregation DOES work with BOTH networks.
Here are some observations for those are interested in getting the international version and use it in the US:
AT&T:
Surprisingly, VOLTE works out of the box with AT&T. This is a first for the international unlocked model. My AT&T SIM already had this feature provisioned on my account and it just worked when I placed the SIM into the Note 10+.
HD calling works as well (tested a call to another AT&T customer and a Verizon customer).
The device can do 2xCA with bands 2 + 12 and bands 2 + 4.
Speed is almost the same as the US model when using these frequencies.
No WiFi calling
Project Fi (T-Mobile).
VOLTE works.
HD calling just between T-Mobile customers.
The device can do 2xCA with bands 2 + 4. I have not seen it do 4+12 or 2+12 yet.
No WiFi calling (but that's normal to any phone that's not a pixel with Fi).
Verizon:
To be tested still
Like I mentioned before, if your international version comes from a European country, for some reason carrier aggregation no longer works. If you then flash an Asian firmware, have an Asian country SIM inside the phone when you flash the firmware and do a factory reset after you flash, carrier aggregation will start working with a US SIM afterward.
DeeXii said:
It should be noted that with Exynos F models, USA Carrier Aggregation does not work properly.
While the phone will function properly, it will not have the same network speeds as an equivalent USA model.
For example, I had in my possession a N960F and did a speed test next to a N920T (Note 5) and I was getting like 70-90Mbps down on the Note 5 and was only getting 15-30Mbps on the N960F in the exact same spots.
I've tested this many times and actually also with the N950F before that.
I'm only posting about this just to make people aware. I'm, sure there are some that will take the trade-off of slower speeds to gain the ability of root and development, but there are also some out there that prefer that their speeds not be gimped.
This has been discussed on many XDA threads in the Note 8, S9, Note 9, S10 forums for a couple of years now and can be duplicated exactly as mentioned.
If anyone has figured out a way to get proper USA CA on F model phones I'm one of the first that would love to hear about it.
I'm sure @iunlock would also.

It's not the model that causes this - it's your lack of the correct CSC. If it has a compatible CSC, it works just fine.
I'm currently debating rooting my new Note 10+ 5g to port over the T-Mobile CSC from a T-Mobile model like I did with the Note 8.

That is 100% incorrect.
While flashing the CSC is a must on any locked or F model Samsung phone to enable all carrier features like video calling and VoLTE. It does not give the CA tables that are in the snap dragon's baseband to an Exynos device.
There for if you are on a US carrier and have a N975U/U1 next to a N975F, the speeds on the N975F will be significantly less than the N975U/U1. I'm surprised you have entered this debate again with these views considering your experience in the matter. Once again we have obtained an F model and tested against US variants and have concluded that as of now, simply flashing the CSC from T-Mobile or any US variant does not enable USA Carrier Aggregation on Exynos models. I am not trying to be mean or agumentitive here, but when you have people ordering from overseas potentially running into situations where they cannot return a device, it is very important to have 100% accurate information.
It should be noted that while on 5G it may be different because I do not think 5G uses the MIMO type actions of carrier aggregation. But also with that said. 5G phones do not use 5G 100% of the time. (See how 5G works for more info)
TLR - Yes unlocked international models "work" on US carriers. However their speeds will be much slower than on a US variant because international variants cannot do the Carrier Aggregation that US carriers need for full data speeds.

I'm not sure where you got that information, but quite a few of us posted screenshots in the Note 8 days showing the CA tables on our N and F variants. I believe the CA combo info is within the keystrings.dat file but don't quote me on that.
Also - nobody should root their phone (needed to flash USA CSCs on N and F variant Samsung phones) and expect to be able to return the device afterwards. We are taking the risk anyway by ordering an overseas model phone.

I'm getting my info from several tests done by myself and several others.
The tests on our Note 10 devices match exactly the tests we have done on Note8 and Note 9 international Exynos F models that people have been testing for years that simply do not do US Carrier Aggregation, even with the US CSC.
We have had two Note 10 F models, an unlocked US model, and a T-Mobile US Model. At the same exact location, my old Note 5 N920T pulls higher download speeds (because of Carrier Aggregation) than my brother in law's N975F.
Go find a T-Mobile N975U and see for yourself, however, I am not sure where you are located. I am sure there are some places in the country that might produce the same speeds on their phones simply because the towers in that area are older and do not have all of the bands some major markets have.
In those locations, you will probably see average download speeds anyways. In this situation, an Exynos model is acceptable as the speeds will be the same. However, when traveling the data will still be gimped obviously.
Bottom line is that if a person in a major market gets an N975F and flashes the T-Mobile CSC they will still have gimped data speeds when compared to a US snapdragon variant, period.
Believe me, there is no one more than myself and @iunlock that want CA to work 100% 1:1 with the N975U model but it's just not the case. It is what it is.
Also, it should be noted that CA does not just affect download speeds. It can also affect signal reliability in certain situations.

I take this as a challenge, my friend
Hold my beer...
Would flashing a different CSC get rid of the current carrier boot and shutdown animation? And, to flash a Tmo CSC on a rooted sm-n975f be as simple as flashing the new CSC in Odin?

Hey Kalm_Traveler. Long time no chat.
Please do that. I just picked up a SM-N975F/DS and would love to see that happen. I remember your old N8 thread well.
To update my earlier reply, just tested the FD model with Verizon.
VOLTE works out of the box.
HD voice works.
I've seen 2 x CA with bands 4 and 2 and then 5 and 2.
So while we are both going to see 3 x CA or 4 x CA, it can def do 2 x CA on the 3 carriers I tested.
What surprised me that VOLTE works out of the box for all 3 carriers.View attachment 4819270

Question AT&T and International/EU 9 Pro

So, I have been watching the 9 Pro as my next phone (upgrading from HTC U12+), but am really disappointed in a couple of things: (1) it appears there is no plan to certify the US version for AT&T 5G, and (2) no Astral Black for the US.
Since the 5G aspect is unlikely to change anytime soon, and AT&T 5G isn't really all that great anyway from what I hear, is there any downside to buying an EU Astral Black model and using it in the US? I'm still researching all the bands, but it appears the EU model is only missing two LTE bands in use by AT&T (Bands 29 and 30). To be fair, the US version is also missing Band 29 for the 700MHz spectrum, but does contain support for Band 30 at 2300MHz.
I'm going to log which bands are being used where I live and work but, if I will be limited to 4G/LTE anyway, I'm not seeing a downside to buying the EU version. Am I overlooking something? Any thoughts, suggestions, or input is greatly appreciated.
EU has additional options that neither the TMO or US int models have. At&t is behind on 5g deployments anyway so you shouldn't miss out on much, Verizon and TMO would've been better for that. As far as general reqs go, I don't see why not.

I believe that is true - I just want to make sure I'm not inadvertently limiting myself with 4G/LTE coverage by buying the EU version. I don't really care around home/work, as there is usually wifi available. My bigger concern would be coverage in my home area that might get dropped now due to the EU version missing a band that is available on the US version. Or, perhaps when traveling if the EU version is missing bands that other networks (roaming) may use.

You are correct. I call ATT about once a week asking if they're going to certify/whitelist OnePlus devices. I figure the more complaints they get, the more they'll be inclined to investigate it.
To add to this, most people I speak to have never even heard of OnePlus, which makes the conversation troublesome. Be completely prepared for ATT employees to feed you bad information, say your device isn't compatible (does not have the required hardware), is inferior to Samsung/Motorola/iPhone, and try to sell you a new phone or sent you a new SIM card.
I've posted before about calling ATT. I feel everyone who has their service should call on a regular basis. Squeaky wheel gets the grease.

And the strange part is they have the 9 and 9 Pro listed on their list of devices that will still work on their network (VoLTE) after they shutdown their 3G service next year. Gives me hope they will certify at some point.
I run this phone on AT&T, and while I don't get 5G speeds, I get very fast LTE+ speeds of around 200mbps.
Thanks all for the input. After some more thought, I believe I have decided on the pine green US version. It's going to be in a case anyway, and I've had very few cases that aren't black. So, if it will be black anyway due to the case, I might as well get the US version. Plus, I think the black case and green camera bump will look sharp.
Reviving an old thread, rather starting anew:
I want to get the 9 pro for T-mobile use in US. I need dual sims and want custom roms...
I saw that "toolhas4degrees" said they had a Chinese model with EU firmware. I don't know if he changed the firmware himself or what... A bit out of my capabilities.
Simply put: What would I need to do (if anything) to get the EU (LE2123) OnePlus 9 Pro to work with T-mobile?
Thanks!

Question .A5 facotry image on USA Pixel 6

Hi!
I have and USA Pixel 6 Pro (G8VOU) that I use only in Europe.
Which factory image should I flash between .A1 (global) and .A4 (EMEA Carrier)??
Thanksss
The US Pixel 6 variant has an extra mmWave antenna, I don't know of anyone that installed the European version (A4) on top of a US Pixel 6 (European Pixels do NOT have the mmWave antenna). It might cause problems, it might not matter. If you want to stay safe, going for the international A1 global variant might be a good call, but that one might cause reception problems in Europe (as many have reported since the December patch).
It might be also worth a try to install the US version, since that one is made for your device, and basic reception should always work. Mind though, that in case you need to switch between versions, it will probably require a factory reset.

I'm wondering if that's accurate. There are three variants of the P6P (all of which should accept any of the official firmware builds). From Learn which Pixel phones can work with which kinds of 5G, there are:
G8VOU (AU, US)
GLUOG (CA, DE, FR, GB, IE, TW)
GF5KQ (JP)
Of those three, only the G8VOU (AU, US) and GF5KQ (JP) work with both mmWave & Sub-6. Why would they have different model numbers if there's no hardware difference?
Great point and I'm curious too. I'm referencing an article I read describing the differences in the pixel 6 versions. In that article they said the Pixel 6 pro was the same and didn't differentiate hardware. Now I got to find that article. So I'll update my comments with the correction when I get a definitive answer.

You are correct. I was referring to a pre-release article that obviously wasn't accurate...And I remembered it wrong.
There is a hardware difference. As mentioned, the non mmWave country versions lack the dedicated antenna.
04:00 minute marks shows the international version without the antenna.
02:50 shows the US Variant, with the dedicated antenna and an attached cable
