Alpha 850M vs 850F? - Samsung Galaxy Alpha

Hey everyone, noob here. I have an 850M on the way. I chose that over the A based on all the info posted on several threads. I was a bit concerned that the M wouldn't have all the necessary LTE bands for TMobile, however there was one thread here that clarified any doubts. After ordering the M, I saw that the 850F is available in aqua blue, very cool! It's a unique color I've never seen on any other smartphone. I really want the blue color instead of the gold version of the 850M that I ordered. I searched extensively, but can't find any definitive answer on the 850F. Some say the F is missing the 1700/2100 bands, others say it's present and works with Tmobile just fine.
Has anyone used the 850F on Tmobile, if so how are the LTE speeds? In my area, Tmobile LTE speeds are blazing fast. I consistently get 25-35 mb on an old LG G2, off peak hours I can get as high as 50-60 mb. I want to get the 850F in blue but not if it can't be LTE compatible. Any feedback or comments would be appreciated!

The Samsung support page for G850F says:
GSM (2G)
DCS 1800 MHz, PCS 1900 MHz, GSM 850 MHz, GSM 900 MHz
UMTS (3G)
B5 (850), B2 (1900), B1 (2100), B8 (900)
4G FDD LTE
B5 (850), B2 (1900), B7 (2600), B8 (900), B20 (800), B3 (1800), B1 (2100)
That's all I can say...I use it in germany...

Lumia 920

Hello people. I just watched the press release on the Nokia Lumia 920 and I must admit it looks really enticing. The design is beautiful and for some reason WP8 seems like it could be a very productive device. I just wanted to get your thoughts on it, also I don't think it will come to Verizon but none the less seems like a really awesome phone!

Wrong Forum but Personally i all around like the look of the Lumia 900 better. I hate the gloss and the 900 just look more appealing except the fact its running WP7
None of it matters if WP8 doesn't stick. As of right now, Windows Phone is a failed OS, and as someone who has been burned by previous failed OSes (WebOS, for example) you couldn't pay me enough to be an early adopter.
What bands do the Lumia 920 support?

What I find confusing is the bands supported. By 2100Mhz, do they mean IMT (2100/1900) or AWS (2100/1700) ?
I wonder where in NA it could be used then... no 700Mhz neither.

Differences between T-Mobile HTC One and international HTC One

Hi folks! I found brand new T-Mobile HTC One for sale. The guy only wants 600 leva (about 350-400$) or HTC One X + 100 leva (about 70$). I want to know is there a big difference between both international and T-Mobile HTC Ones? I check in T-Mobile site and there it shows that it works on 850/900/1800/1900/2100 MHz but on htc`s site it shows that it works only on 850/1800/1900 MHz. In Bulgaria most common 3G is on 900 MHz. Will there be a big problem with network? And can I flash ROM`s from international forum? What could possibly happen if I flash ROM from there?
P.S. Sorry for my English, it's not my native language as you can see

Aside from the radio difference, the international one is unlocked.

Tmobile has more frequency than the international version. More freq the better.

T-Mobile: Has the Tmobile Radios, not unlocked 32GB
International: Doesn't have Tmobile HSPA+ Radios so you'll need to be in 4g LTE Range to get those speeds, comes unlocked, 64GB
I was also researching between the two. Getting the Dev would have been cheaper and had more space but the radios were the biggest problem for me. I wanted to make sure I had the best possible signal.

Take a look at the specs:
http://www.htc.com/www/smartphones/htc-one/#specs
You don't say if your T-Mobile One is from Europe or the US. The US T-Mobile model does not support 900 HSPA. T-Mobile Europe will support that. The international model has different radios.
For those that replied, the Developer edition is a hardware copy of the US ATT version, which also does not support 900 high speed data.
Here is a copy of the page:

Yes, I believe that is correct. I was worried because you didn't state it was a European T-Mobile model. T-Mobile is the only one that has both a US and European model - and both are different.
I have an unlocked T-Mobile and use it on ST AT&T. Never seem to need this "missing" 900mHz band. Why would I need it again? I had full service from UT to NV (the desert). 4G most of the way, too.
Genuinely curious as it works perfectly everywhere on AT&T's service.
Isn't 900 being phased out?

LTE Compatibility

Anyone know what LTE band or bands the Nexus 9 operates on? I need to know where it can be used country wise as band choice varies wildly.
I want to know this too.
Is there anybody who know what lte band support on Nexus 9 LTE version?
I found it.
http://www.htc.com/us/tablets/nexus-9/
Network
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

seems very good.

My Moto G3 doesn't connect to 3G or 4G band

Hi, last week I was given a Moto G3 XT 1541 from Spain. The problem is that it doesn't connect to argentinian carrier's 3g or 4g bands, it only works on 2g. A friend told me that I could work it out flashing the firmware of another model like XT1540 which works perfectly on 3g and 4g. Is it a firmware block? Can I solve it flashing another model's firmware? If I flash it, will my phone work or it will be a stone? Thank you ver much.
Yes, you can.
Moto G 3rd generation does not have capability of 2300 MHz bandwidth.
Requirements for a4G
1. A handset that supports 2300Mhz.
2. A 3G plan.
3. USIM (they provide free upgrade)
4. 4G network coverage
I think even HSPA or HSPA+ might not work for me on this phone. I am using a T Mobile family plan here, and comparing th bands given on the website:
"4G (HSPA+)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G (HSPA)
With 3G, theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)"
"Moto G (XT1550)
LTE (1, 3, 7, 8, 28,40) UMTS/HSPA+ (900, 2100, 850 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)"
It seems that the uplink is unsupported by my phone and so the phone is unable to use the HSPA/HSPA+ bands. I think the only way to use it is to unlock the 1700 MHz band on my phone.
XT1541: GSM/GPRS/EDGE: 850, 900, 1800, 1900 - UMTS/HSPA+: 900, 2100 - LTE: B1 (2100), B3 (1800), B7 (2600), B8 (900), B20 (800)
Argentina UMS/HSPA+ works on 850 and 1900.
This phone will only get 2g where you are. Flashing another firmware will not fix this.

S9/9+ Unlocked will not have band 71 for T-Mobile

I read conflicting answers on best buy versus frequency check so I called Samsung and was told it's not.
Here are the bands if you care"
B1 2100 B2 1900 PCS B3 1800+ B4 1700/2100 AWS 1 B5 850 B7 2600 B8 900 B12 700 AC B13 700 C B17 700 BC B18 800 LOWER B19 800 UPPER B20 800 DD B25 1900 + B26 850 + B28 700 APT B32 1500 L BAND B38 TD 1900 + B40 TD 2300 B41 TD 2500 B42 TD 3500 B66 1700/2100
Is this for SM-G960F? What's the implication of it not having band 71? Coverage/speed issues?
What is going on, so confused. I also contacted Samsung about this twice just to make sure and both times, two different people have said band 71 is supported by the unlocked US version.
This is the SM-G965U. It's for T-Mobile's rollout of the 600mhz service though at this point is on available in certain areas.
Found this map to show the areas.
http://maps.spectrumgateway.com/t-mobile-600-mhz-band-71-deployment.html
We are hoping they wouldn't make different hardware and somehow you can can unlock it by flashing T-mobile firmware but according to Best Buy's site and Samsung support it's not there.
Does "Unlocked US version" only mean carrier unlocked or does it also have unlockable bootloader?

Just carrier unlocked but sometimes that means it can be easier to root.
It's there according to techwalls
coming from a s7 edge and s7 family, the tmo bloat isn't that bad. I do want the band coverage for lte 71. but would the updates for the unlocked version be rolled out quicker?
G960U and G965U both have Band 71 support.
This isn't the first time customer support reps have gotten something wrong.

I believe so. Rather than updates having to pass through Samsung and T-Mobile development teams, you would only have to wait on Samsung. Of course faster is relative and Samsung alone may take forever with updates already vs. Another phone maker.

If i'm not mistaken, 71 is an LTE band. I'm not on t-mobile so I'm not 100% on this.
Decided to peruse the FCC docs for the Galaxy S9, located here: https://apps.fcc.gov/oetcf/eas/repo...id=iZpmwirNeCdRpxZDqp7ksg==&fcc_id=A3LSMG960U
Specifically the "HAC Key Feature letter" doc, if I'm reading/understanding it correctly, both the SM-G960U and SM-G960U1 (unlocked model if they're following the same model number scheme as last year) will support Band 71 LTE.
I guess direct linking to the doc is not allowed, but you can open it from the link above.

*** You Said..." if it doesn't have band 71 I will send it back." So just how would you know if the device has that band is is capable of utilizing it?? Please explain??

Well I hate to say this but if my Uncle had breasts he'd be my Aunt. I have had quite a few conversations via Twitter and in chat sessions with Sammy Tech reps and at this point I would say to you that they don't know wether to scratch their watch or wind their asses.
I have gotten no less than 6 different answers from them and sent a complaint up the line to Senior staff who might shed some light on all the different responses that keep getting disseminated to the public.
The unlocked Galaxy s 9, us version, does support band 71. I am using the unlocked version.
Assuming it supports band 71 doesn't mean band 71 is enabled in the modem. two different things!
So that being said and "If the device has Band 71" how can we test if the modem software is in the device?
