does band 12 do anything for at&t users? - Nexus 6P Q&A, Help & Troubleshooting

I'm pretty sure I know the answer but I just did some googling and I wasn't able to find anything concrete. I'm currently bootloader unlocking/twrping/rooting and I figured as long as i'm crack-flashing i might as well load the band 12 radios if it would help me out. I know band 12 is live in my area but I don't think at&t users get any benefit from band 12. from my research it's mainly beneficial for t-mo and small carrier customers?
Thx to anyone who can help a guy out

T-Mobile only

No AT&T has low frequency spectrum in other bands. It's not as big a deal because AT&T has a fair amount of spectrum in those bands all over the country.
Band 12 is so important for Tmobile because that is their only 700mhz band which means without that band you can and probably will have issues inside buildings unless you are in a heavily saturated tower area. Add to that the areas that have band 12 are pretty tiny on a nationwide level it becomes important if you can get it. It does make a big difference.

OnePlus One Carrier Compatibility

Hey everyone!
I've been looking on the OnePlus forums lately, and lots of people have questions about carrier compatibility with the One. Personally, carrier compatibility is the biggest factor when it comes to buying an unlocked phone, so I decided to make this thread to help guide people with compatibility with their carriers. According to OnePlus's website, the bands that are supported are as follows:
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands: 1/2/4/5/8
LTE: Bands: 1/3/4/7/17/38/40
Now, I am going to start with USA compatibility. If anyone else would like me to add compatibility with their carrier, please reply to the thread, and I'll see what I can do. Hopefully, this will benefit all members of the community.
USA
AT&T
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 5.
LTE : Only supported on bands 4 and 17. Bands 2 and 30 are not supported; however, they are usually only deployed to create extra bandwidth in high capacity areas. Band 17 is AT&T's major LTE band.
MVNOs of AT&T : Straight Talk, Net10, AIO
T-Mobile
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 4 ("4G" HSPA+)
LTE: Supported on currently deployed Band 4. However, T-Mobile plans to deploy Bands 2 and 12 to extend coverage. So, if you have LTE signal now, you're okay. If you don't, then you most likely never will with the One.
MVNOs of T-Mobile : MetroPCS, Ultra Mobile, Lycamobile, Straight Talk, Net10

How to figure out whether AT&T or T-Mobile would be best for Straighttalk?
UNITED KINGDOM
It'll work fine on:
EE (Bands 3 & 7 supported by OPO)
Partially:
Three (Band 3 supported, Band 20 isn't by OPO. Band 20 people say will be used for rural areas)
No LTE:
O2 and Vodafone (Both use Band 20 which isn't support by OPO)
3G will obviously be fine however.

You check the coverage map in your area for each of those providers. The one with better service in your area is the one to go for.

I have the Samsung Galaxy Light SGH-T399. It works on T-M's current LTE 1700/2100MHz (band 4), but also 700MHz (band 17), which T-M just purchased from Verizon. A few other newer T-M phones are also made to work on this 700Mhz band. It seems that they were planning ahead.

The OnePlus One also works on this 700HMz (band 17) frequency.
Good news for those lucky enough to have LTE with T-Mobile. The 700 band penetrates buildings better, so you'll have a better signal inside Wal*Mart or if you live deep inside a large apartment complex.

Very true. T-Mo will probably use this band to expand coverage, Good catch :good:
However, it should be worth noting that T-Mo plans to cannibalize (AKA "refarm") its EDGE network into LTE. This may sound great; however, this EDGE that they will be converting will be broadcasted on the 1900 MHz spectrum (Band 2 LTE). The OPO will not support Band 2, so OPO users on T-Mo will not be able to take advantage of LTE in many rural areas and markets.
Will the phone work in India? Vodafone is my carrier.
Portugal
2G - Full compatibility with Optimus, TMN and Vodafone
3G - Full compatibility with Optimus, TMN and Vodafone
LTE - Compatibility on 1800MHz and 2600MHz frequencies which should cover big population agglomerates on Optimus, TMN and Vodafone. 800MHz left out, so outside cities (and probably inside buildings and small cities) it will most likely revert to 3G.

Curious, was this written by OnePlus's P.R. team? Because it really downplays what I consider one of the biggest problems with this phone, namely that it is missing half the LTE bands used by AT&T, the biggest OPO-compatible carrier in the U.S.
The argument, "Oh but they're barely deployed", is pretty weak. The fact is the bands ARE deployed, and they're only going to get deployed more because carriers aren't exactly in the business of wasting their valuable licensed spectrum. In high traffic areas where they're in use I assume it would be pretty desirable to have them because the other two bands might be over capacity, or maybe they aren't even operating on the tower you're hitting.
Everyone seems to be brushing this off. I guess it's OK to settle after all?

I agree, the lack of proper LTE bands really are a turn-off for this phone. Just look at our friends in Europe, whose widely-deployed LTE Band 20 is not supported. I'm not saying that the LTE bands here on AT&T are optimal, but it's worth pointing out that it could be worse. The fact that the One supports Band 17 should be satisfactory for many users; it's AT&T's low-frequency band, so theoretically, it should cover the most people. The higher frequencies would only make sense being deployed in areas with mass congestion. So in cities, it's fair to assume that you'll get lower-than-average LTE speeds.
Now, it could be worse. Take a look at T-Mo users (like myself). We're pretty much getting screwed over. Band 4 LTE, the band that they're using now, is very high frequency. Building penetration sucks. Coverage and range sucks. Their network currently is weak. The new bands they are deploying will be lower frequency, so they should provide more coverage and reliability. However, of course, the OPO doesn't support them, which is a major blow to T-Mobile USA customers.
But hey, for $300 for an amazingly-spec'd phone, we have to expect that some compromises had to be made.

[Q] 3G/4G coverage in S California by specific UTMS/HSPA/LTE band

Hello,
I'm looking for intel on 3G/4G coverage in San Diego, Palm Springs and Los Angeles, initially for T-Mobile US, but potentially AT&T as well. My own proposition is that I'm travelling from the UK to Southern California at the end of the month, with my internation Samsung Galaxy S4 Active LTE (i9295). I've started a separate thread asking about whether others have been able to add additional UTMS/HSPA/LTE bands to their i9295 phones here.
In terms of T-Mobile I'm keen to understand whether there's coverage of UTMS/HSPA on band 1 or 2 (2100 or 1900MHz) and/or LTE on band 1 (2100MHz), and whether UTMS/HSPA/LTE band 1 will work without band 4. If SoCal has this coverage, then I may be able to use my phone as-is, having compared band information here:
- http://www.gsmarena.com/samsung_i9295_galaxy_s4_active-5446.php
- http://en.wikipedia.org/wiki/T-Mobile_US#Radio_frequency_spectrum_chart
In theory, AT&T could also have LTE band 5 coverage (but is this common in cities?) and also UTMS/HSPA on bands 2 and 5 which my phone would already support.
So my question is, whether there is any information out there, whether anecdotal, actual data sets or whatever, which would detail what bands are actually available in these cities?

Band 12 - T-Mobile

So I'm not the brightest with the different frequencies etc... What I do know is that Band 12 on T-Mobile has greater building penetration, and that it's currently not supported on the Nexus 6P, despite the phone having the band. My question is, what functionality do I lose? Aside from having more penetrating power, which gives me better signal, do I lose anything else? Honestly, I'm pretty sure Band 12 isn't even in Columbus, Ohio (where I am) yet... but I don't wanna buy this phone and then Band 12 go live here and then I lose LTE, if that's even what happens... or would it just resort to the current band 4?

Thats trouble for you. From what I understand there is a long certification process to get the certification from T-Mobile, especially if they do not sell the phone. The Nexus 6 DOES support the T-Mobile band 12:
Unlocked devices
The following unlocked phones not only support LTE band 12 but all other bands required to be compatible with T-Mobile network (LTE bands 2, 4 and 12, HSPA+ on AWS and 1900 MHz, and GSM on 1900 MHz) however band support is not the only requirement. T-Mobile issued a statement regarding band 12 unlocked phones: All Band 12 LTE devices on our network must support VoLTE, E911. Currently only three unlocked phones supports VoLTE and band 12:
Nexus 6 XT1103 (US model)
iPhone 6s A1688 and A1633
iPhone 6s Plus A1689 and A1634

well tmobile has already confirm the 5x/6p will work on their network... im just wondering what the lack of band 12 support (for the time being), means for me. i assume i would continue to run on the band 4 that i do now.
Not sure if you've found the answer to your question or not. If you dont have Band 12 where you're located then its really a moot point. I'm in Phoenix and there is a TV station still operating on the 700Mhz Band 12 spectrum so I dont have it. However, if T-Mobile lights up Band 12 and these phones havent received their certification then they will not use Band 12 at all. That means you're limited to Band 2 and Band 4 LTE. Assuming you dont have Band 12 in your area (it appears you do not based on the de-facto map that most cite reference to is here http://www.tmonews.com/700mhz-lte-map/), your coverage will remain the same as it is now.
That being said, Google has stated that they are working with T-Mobile to have the 6p certified by the time the devices ship. So if that holds true, and T-Mobile rolls out Band 12 coverage in your area you should theoretically get better indoor LTE coverage since low-band spectrum travels farther and has an easier time passing through obstacles like block walls. Until then, you should have a similar coverage experience to what you have now. You're not "losing" anything to answer your question.

Verizon compatibility?

Has anyone heard if this model will work on Verizon? All other carriers suck in my area.
I highly doubt that it will, given that none of the previous models have been able to. From my understanding, GSM technology is faster and allows for better connectivity than CDMA networks like Verizon, which is why it is the only type supported by phones made in places other than North America. I could be wrong, but judging by the past I don't think it's very likely
Well they're trying to make this a global phone so if Verizon is CDMA:BC0 then it'll work as that's what it's listed to work on along with 33 others network bands.

No Band 13 = big problems for Verizon trying to get LTE working normally. It would work on the network I suppose but that is Verizon's main LTE band and also the only one that doesn't overlap with other carriers, like 2 and 4 do.

So this should work on sprint?
I put my Verizon Sim in my OP5 and it did get signal, but it showed 1x and right above it 3G. I did a quick speedtest and I was at about 1MB/s. I get around 70MB/s with my iPhone. So I guess the answer is that it does work, but it does not work well. I also don't know about MMS, I tried SMS and phone calls and that worked fine.
Will be tested on VZN as soon as mine arrives on Friday, if its not working on Verizon, I will be sending it right back to them.

It should function but it DOES NOT have band 13, which was mentioned in a few places now. Considering the price and the potential compromise, it's not worth it.
It has bands 2 and 4 but missing 13. No go for me.
Why is it so hard to add band 13. You have all the rest on there. Idiots.
We Verizon users hate Verizon devices but i will not switch networks. If one plus wants to be a true flagship killer and sell a lot of phones, they should include all bands. Verizon is the biggest network out there.
Thats my opinion.

I totally agree with you my dear Bulgarian friend, makes no sense at all to me. But I will see and give feedback as soon as mine arrives on Friday. I know from a fact that if you live in a fairly big city, band 13 is really not needed, down in ATL I am good with 2 and 4 on all devices. Tested on Mi Mix, which also lacks the band 13, but it has 2 and 4. Anyway I will let you all know on Friday.

yeah, I'm usually on band 4 here in my town, but when I'm in my office building, it does switch to band 13 since it needs that lower frequency to penetrate the building. So I'd imagine I wouldn't have signal or very weak signal in my office. But I'll try it, mine's set to arrive on Friday as well.

I dont think so too, it will be interesting to find out. I am glad they are going the step forward to include more bands, but VZN strikes again. I am sure even if they added band 13, without VZN whitelisting their IMEIs, its still unusable. We will see.
Quoted from android central
So no Verizon compatibility?
Nope. It may look that way because the phone technically supports one of Verizon's legacy CDMA frequencies and a handful of its LTE bands, but OnePlus has no intention of ever officially supporting Verizon.

Differences between A320F/DS, A320F, A320FL and Usability in the United States?

Hi,
So, I'm interested in getting a cheap 4.7" Android phone to use in the United States and sometimes in Canada. I zeroed in on the Galaxy A3 2017. The model that works best in North America is the A320Y, but so far I've only been able to find it online at some store in New Zealand. Since finding the answer to the question, Will shipping the device from NZ to the United States cost customs fees (and if so, how much)? is a question harder to answer than the question, Where is Jimmy Hoffa?, I've begun considering getting one of the models listed in the title of this thread.
But there's a problem. Those models in the title don't work on US LTE. Actually, according to frequencycheck.com, the A320FL has one LTE band (Cricket/AT&T) and the other models have none of the LTE frequency bands. I wonder if frequencycheck.com is accurate. I'm also wondering if there are other differences between those models. I'm also wondering what happens if I put a Cricket SIM inside these phones. Even though frequencycheck.com says I will get no LTE bands, will putting a Cricket SIM inside suddenly activate an LTE band?
The other question I was wondering: Do I even need LTE if I don't care much about download speed? Maybe HSPA+ or whatever it is will be good enough? If I don't have LTE, will I get less reception indoors or outdoors, or will I get the same exact reception/coverage but just be relegated to 3G/4G/HSPA+ service? What is the benefit of LTE besides data speed?
Finally, which one of these models has the most ROM support? Can they all be bootloader unlocked?
I know I'm asking a whole bunch of questions at the same time. Sorry. I appreciate any help I can get with this!
To answer some:
That website appears to be accurate. Doesn't only list AT&T for a320fl once expanded.
As for SIMs activating bands, I haven't seen it on Samsung, only RRC Release, VoLTE, LTE CAT, maybe individual CA combos. The disabled bands are shown as CAL_DEFAULT vs CAL_PASS. Guess it's like Snapdragon.
HSPA+ vs LTE
The range of 3G/4G is close with the same frequency, but 4G performs better at cell edge (low signal).
Speed (anyway)
Well, 3G is usually given its own spectrum at first, then the 2G is refarmed into 3G. Today, 3G gets refarmed to 4G. This leaves 3G with a small amount of spectrum, it becomes prone to interference. It's bit like multiple tv/fm stations on the same channel number. Other 'tv/fm stations' have to be filtered out by the phone, this lowers the speed. 4G gets some too, along with echoed complex signals, but it gets less.
3G supports up to 5MHz per carrier, 4G up to 20MHz. 3G can have carrier aggregation, so 5+5+maybe 5. Expect up to 2 carriers (not every combo) on 4G, unless a specific SIM is detected in specific phone models. Along with that, 4G can have better spectral efficiency.
If you are going with 3G(HSPA, sometimes called '4G') anyway, you should know that there are these states (usually called fast dormancy) to save power.
DCH = Full speed.
FACH = Up to 32kbps. 4kB/s. Maybe RRC Release downgrade is visible (H+ to H).
PCH = No data.
Anything below is further away from data.
For high performance, keep the speed above 4kB/s, at the cost of battery. LTE has a faster start.
Sometimes, the speed is simply constrained by backhaul, the internet access that goes to the tower.
Thanks. So, to your knowledge, the F and F DS variants shouldn't work on LTE in the United States? I was in a live chat session with someone on Samsung's UK website and she said that the F variant would work on LTE in the United States. I then sent them an email to confirm and they replied with:

According to every other (not alternating) source the LTE band 2 and band 5 is supported in the US (and the entire spectrum of these bands). So, it supports some bands. Check if the signal of those bands (for your mobile network operator) are available in your location. Ask again, specifically for band 2 LTE(4G).
