Band 12 on International variant - Nexus 5X Q&A, Help & Troubleshooting

Any way to get band 12 working on the h791? Not really expecting much, thought I'd at least give it a try.

Tmobile Compatibility

Hello,
I'm thinking about buying this phone, I would like to know if this phone is fully compatible with tmobile?
Thanks.
Tmobile uses bands 2, 4, and 12 with 12 not in use yet or not broadly available (recently acquired from Verizon). The ZF2 has bands 1-8, 17, and 20. Everyone who has posted says that it works perfectly on Tmo. The trial SIMs Asus gave out at the US announcement were all Tmo SIMs as well.
Works great on t-mobile for me. No band 12 of course.
Same here. Tmob in NYC works well (better reception in buildings with the newest update actually), but no band 12.
Is band 12 necessary? What effect does lack of band 12 have?

Band 12 is not necessary. I'm using the Zenfone 2 on T-Mobile. No reception or speed issues. Pulling ~60mbps down/~30mbps up.
Seems to be working on Tmobile Prepaid as well.
Band 12 is new and has limited availability. I think it is supposed to have better indoor coverage. I don't think it is a big deal. Band 12 phones are just starting to come out on t-mobile (I don't think the iPhone has it).
Compared to my Note 4 from Tmobile, the Zenfone 2 has been getting me better reception. I switch often, but been staying with the Zenfone more lately.

Same here. I have an iphone 6 plus that I cant stand so I switched to the ZF2. The ZF2 gets way better reception..

WIll this be a good phone for roms in the future ? USA LTE bands

Im wanting to run this phone for usa tmobel it only supports 3 out of 6 lte bans.
Im on wifi most of the time so it not a big deal but I would like at least 10 up and dowm.
I was going to get the Xiaomi Redmi Note 8 but this looks like it may be a bit better for roms, am I right?

Ordered 7t through Amazon, have questions.

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.

I am from India and I ordered 7T from amazon and I got the Indian variant (HD1901).

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!

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 US carriers that will support POCO F3 or RealMe GT 5G

Hey Everyone,
Currently have a Xiaomi Redmi Note 5 on AT&T, but recently got the notification that AT&T is shutting down their 3G network and my phone will not be usable. Looking at switching to another carrier/MVNO and was considering between the POCO F3 and RealMe GT 5G.
Can anyone recommend carriers/MVNOs where these phones would possibly work on. I know frequency checker/Kimovil provide the compatible bands. But considering both phones don't have Band 71, I just wanted to check if anyone has been able to use these phones on US carriers and if so how did you go about getting the phones activated with the carriers.
Thanks

Well I'm Att and I just ordered the Poco f3 a couple of hours ago. So by next week I'll be able to tell you. I was going to go with the real me gt but didn't because the global model can't be bootloader unlocked and that to me means a no go. If I can't root it I don't want it. It's only a little bit better with specs it has the 888 and 65 watt charging which makes me a little jealous but I have to have viper4 android on my phone so I went Poco f3.
What band do you use for 4g lte? I use band 4 and it's never been a issue. I don't plan on 5g because I barely get 4g where I live

Thanks for the response Techguy, I would be interested in knowing how it works out for you.
Considering that the Redmi Note 5 Global version only has Bands 4 & 5 for 4G, and Bands 2 & 5 for 3G, I believe it is running on HSPA+ on AT&T Prepaid mostly, as I only get the 4G symbol, not 4G LTE.
I did see for the RealMe and Poco F3, most of the 4G bands are supported on GoogleFI, just no 5G.

Oh I just meant for GoogleFI, I don't think they have 5G currently not sure, as kimovil says Not Available. For AT&T and T-Mobile, it was 1 of the 3(AT&T) and 1 of the 4(T-Mobile) in terms of 5G bands.
However I'd be interested in knowing how you go about getting this activated on AT&T since it isn't on their Whitelist of phones that they are trying to limit users to.

Im actually getting a free sim card from the government phone through SafeLink but SafeLink is a smaller part of ATT as that's what my sim reads as 4g band Att and I always buy unlocked phones with band 4 and put it in and it works. Nexus 6, S10lite international, moto G4, S7 and S7 edge both all of them same card just insert.
You don't understand they don't whitelist phones they are just saying these ones they know will work with volte and others will to they won't look at every phone. They won't say Poco f3 or realme because they want to sell Samsung and apple not Poco f3. It's money but if it has the band it'll work

I understand that part, but the above is not entirely true, hence the post. AT&T for example are activating devices based on the IMEI, even if it has the necessary bands they are saying it is not compatible. Some folks have been able to get around this and get them to activate the phone, but some haven't been able to
I don't know how true, but they told me if I were to take the SIM out of my Redmi Note 5, they will not be able to re-activate my phone. I haven't tried this so I can't say if this is actually the case.
It sounds like SafeLink may technically be a MVNO to Tracfone/AT&T, I do know outside of Cricket Wireless, a lot of the MVNOs aren't enforcing what AT&T is doing with their direct account holders. But technically since they are under AT&T's network, this will eventually trickle down, but it is yet to be seen how this will be handled by MVNO operators.

Yes I am under SafeLink/TracFone which is subsidies of AT&T. But if AT&T shuts off their 3g network I don't think they will leave it on for the SafeLink people. AT&T doesn't have to activate your phone in America their GSM you might have them tell you that like my brother brought the nexus 6 to Walmart for a straight talk card and the lady said it's Verizon we can't activate it. Well they should have stuck a sim card inside because it works on all 4 carries except sprint and Verizon are CDMA which means your phone does have to be put into their system to work but not with GSM networks like AT&T. Just try it once you have a sim card in the us I don't know if your in the US. They will tell you anything to sell you another phone from them.

I just got my Poco f3 and it works fine on ATT/SafeLink band 4. I don't have 5G so I don't know but it did show the 5g in the upper right hand on display but I checked the speed and it was the same as before so I didn't notice anything 30 to 50 mbps is usual. It's a great phone for the money bench of almost 700k on AnTuTu

Thanks for confirming. How are you liking the phone so far?
I had an interesting conversation with AT&T yesterday on the whole topic. Their device compatibility system is really cracking on International Phones although as mentioned earlier, this isn't the case with a lot of MVNOs. The Global version of POCO F3 I think supports 6 of the 9 AT&T 4G Bands. But it's good that it's working for you nevertheless.
I think the POCO F3 is fully compatible with T-Mobile's network as well at least it is as per their online device compatibility tool, so that's another good option depending on the area.
Got some time to decide what I'm going to do, but it's good to know that the phone does work on US carriers.

Well so far so good, I didn't get it til 3pm today and I think I have Covid or the flu so I have been under the weather. But I ran bench scores and it's flagship level power. It charges faster than I was expecting, 5400mA on ampere when my S10 lite is 4500mA on a 45 watt charger so they make more use of less watts. I love it so far I doubt you'll notice a major difference between the Poco f3 and realme gt 5g. I love flashing custom roms and rooting my devices so if realme won't unlock the bootloader and release source codes to build on that makes the Poco f3 more for me.
I think if you buy a snapdragon 870 device if has the same bands as all snapdragon 870 devices and 888 has the same bands as all 888 because the modem is inside the CPU. I could be wrong I'm going to look into it but I think so.
It's a sweet phone the only difference from a flag ship is it's 1080p screen instead of 1440p and it doesn't have a mega good camera.

That's some good info. Yeah can't be too picky with a budget phone, for a budget phone outside of the camera it has a lot of close to flagship features.
How are you finding call quality so far? That's one thing that wasn't that great with the xiaomi redmi note 5, but attaching a headset resolves the issue.
Hope you start feeling better while enjoying your new phone. Feel better.

I will have to get back with you on call quality because I do use headphones now. I have the master and dynamics MW08 and there awesome for calls. It's to late tonight to call anyone I'll let you know tomorrow. I can't stand the wait to unlock the bootloader. It takes 168 hours after you start the unlock process so 7 days than I can root and install viper4android
