Snapdragon AT&T Samsung Galaxy Alpha Antutu score
Well those Benchmarks on the Exynos 8 core are great.
Unlike Galaxy S4 Octacore Version , on Alpha , the
Octacore Version can use all 8 cores at once under
Peak CPU Loads.
However, this is all academic because there are only
2 different Versions of Alpha for North America LTE and they are both Qualcomm Quad Core , one for AT&T
and one for Bell in Canada.
The Bell Canada version is available unlocked and
SEEMS to have all the bands for 3G, 4G, LTE on Tmobile USA , a great loophole.
See my thread on new Samsung Battery for Alpha also.
I am researching Alpha vs Z3 Compact for myself.
I am very curious if anyone is getting full LTE Service on EXYNOS ALPHA in USA ?
EDIT : For the past 4 months I have had the International Unlocked 850M which has all the Metro PCS/Tmo Bands except the new Band 12 and much better Speaker than qualcomm AT&T version.

So one could essentially take the Bell Canada version, root/unlock it, then be able to use T-Mobile's LTE networks? I know the International version doesn't support LTE with T-Mobile so I've been looking for a workaround with the Bell or AT&T versions.
Yes.
This one is being sold unlocked by Canada GSM and has the LTE Bands for,TMO/Metro PCS and I am no expert but in Reframed Areas the 3G band of 1900 is key.
TPhe 4G LTE and 2 G Bands are present.
I have not dealt with Canada GSM before but suggest a,
Pay Pal or Credit Card Transaction.
Canada GSM has told me via email that this is an Unlocked Canada Bell Alpha with no branding .
http://canadagsm.ca/products-Samsung-Galaxy-Alpha-SM-G850W8-Metal-Unlocked
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1700/ 1900 / 2100
4G & LTELTE 2100, 1900, 1800, 1700, 2600, 700, 850
See these LTE Bands which are not listed on the AT&T Version ?
Should perform well on TMO according to a few sources.
Rooting will not be necessary to be on TMOBILE but you need to find out about that. I would guess Bell Canada would lock the Bootloader on these to prevent
unauthorized , unregulated Hotspot use ?
You can email Canada GSM and ask.
Again use paypal or reversible transaction in case they do not ship or return necessary etc.
This Phone should also be available from the Source and other Canadian Retailers as a Prepaid Locked Canada Bell Device, which you can unlock and use
here in USA on TMobile.
EDIT: I have confirmed with BELL CANADA , that their Alpha supports 3G 1700 AWS band also, so perfect for TMOBILE USA if you unlock.
Bell will not sell outside Canada but will sell outright IF you are in Canada.
Theoretically you can purchase an AT&T Version in USA IF you can find AT&T non Corporate Store that will sell without a Contract at $612. BUT then you need to
Unlock ( carrier unlock) but the Bands do not look right for TMobile.
The one sold at Canada GSM is an unlocked BELL CANADA Alpha 801 perfect for TMobile here,
EDIT: I just purchased the Alpha 850 M which IS an
Octacore CPU factory unlocked and made specifically for North America, Central and South America and the Caribbean.
Box says: " American SIM CARD ONLY , this Product is only compatible with a SIM Card issued from a Carrier in the Americas (North, South, Central, Caribbean)."
IF a SIM card outside the Region is used, you must first make a 5 minute call with American SIM THEN insert
the "foreign " SIM.
First Paragraph is Quote, second I paraphrased.
I find the Octacore faster, and.surprisingly the Speaker is louder and fuller than AT&T Version by far.
On mine it sounds about like ONE of the HTC One Speakers, if there were 2 on this Alpha , it would be almost as loud as HTC ONE M 8 but a little less bass.
Not sure if it is Seiren Audio Chip in the Exynos or I just got lucky, but this Speaker is not tinny like AT&T versions I heard.
Also as many have said, a bit snappier due toExynos and factory unlock.

I just rooted and unlocked mine via instructions here. I am getting an "E" icon, does that mean edge? How do I get 3G to work like people are claiming. I am outside of Orlando with a VERY reliable 3G connection normally.
It won't give you 3g on att lol. Tmobile uses different bands and vibrant does not support att 3g bands, just edge. You should have gotten the captivate, which is made to work on att 3g. It's just a given, almost every phone is like that. You can take most att phones, unlock them to work on Tmobile, but will only get edge, same thing with Tmobile phones. Can't be done...

Apparently it supports AT&T 3G bands
Source:
http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/
Now the question is if the vibrant has both 850mhz and 1900mhz 3g bands.
I was wondering a similar thing. I saw that T-mobile roams on AT&T's networks a lot during a recent road trip, so do you think you can get 3g data speeds over those networks without the need for an ATT sim card?
Just debating whether or not to try to unlock it.
This is really odd - have not seen a device do this before but Engadget generally doesn't lie.
So basically it works on AT&T's 1900mhz based 3G network. In a lot of areas, it could actually work with an ATT SIM once unlocked.
I'm going to give this a try a bit later and will report back how it goes in my area. I know AT&T has both 850 and 1900 based 3G here.
I just took the fam out for icecream and picked up a 3G signal, but back at home on Edge...bah...
Yeah, their 1900mhz isn't as abundant as their 850mhz signal.
The best 'half-band' solutions typically involve a device that supports 850mhz but not 1900mhz, like the HD2 T9193 or HD T8285 both of which get 3G in *many* AT&T areas
Hi peeps,
My research on various forums so far suggests to me that there seems to be contradicting reports whether or not the Vibrant works on AT&T 3G.
I'm planning on importing this phone and use it with an HSPA 850 MHz network in my country, but I'm still skeptical about reception capability of this particular phone. Some reports indicated that the phone works with HSPA 850 while others confirmed that it only works with 1900 MHz band on AT&T.
Therefore, can anybody please confirm if this phone, once unlocked, actually works with HSPA 850. Thanks in advance for any help you might offer.

The phone definitely does not work with 850MHz.
I have a 850-only phone (HD T8285) as well as this Vibrant (1900 only) in front of me.
I just tested an AT&T SIM in both.
The T8285 gets excellent reception here, around 81dbm.
The vibrant on the other hand gets very spotty reception, ranging from 97dbm to around 110.
If the vibrant worked on 850, it would be getting similar reception. Instead it drops to EDGE a lot when using it on AT&T.
Edit: If I go outside, I can get decent 3g and good speeds:

Still, very clearly 1900 due to spotty signal indoors
This is however quite a nice surprise - it opens the opportunity to use it on AT&T's network in places where 1900 3G is solid.
So it does not support 850? Secondly how do I know if I am in 850 or 1900 area?

Most areas are going to have both if anything, so the main thing you're going to want to know is if 1900 is strong enough where you are.
Unfortunately I dont know a truly reliable way to check a specific area for whether thats the case, besides actually trying a 1900 only phone

Not true, AT&T is working on moving their entire 3G network to the 850mhz band... Here in New York City they're exclusively 850mhz unless I'm mistaken.

They've simply re-allocated much of the 3G network to the 850Mhz band, but based on my testing (with a vibrant), they have not totally gotten rid of 1900 3G - it still exists.
The problem with that map is it doesn't differentiate between 2G and 3G.
I have an att sim and I can get 3g on my unlocked vibrant. You can get into the debug screen and clearly see wcdma 850 listed and it is unchecked by default. Only 1900 and AWS bands are enabled. Since we have 1900 att 3g here it works fine. I just haven't had nerve to enable the 850 in the screen to test it. But I have read reports that enabling 850 does absolutely nothing anyway since the hardware does not support that band.

I know it's been posted a few times before regarding whether or not the international version of the Galaxy S III will be compatible on Canadian Carriers (In my case, TELUS) but I am just wondering if it can in fact work. Here's why I ask:
I live in Kelowna, British Columbia, and my current phone is a Galaxy S II from Bell Mobility. I unlocked it back in August of last year to use it on the TELUS network. It ran on the 850/900/1900/2100 MHz bands and I had no issue with using it on TELUS at HSPA+ speeds. With the Galaxy S III it runs on the same bands, so shouldn't it work? Now I've seen people saying that it still requires the 1700 MHz frequency (same idea with T-Mobile), however in my location there is no cellular tower that supports the 1700 MHz frequency (according to Canadian Cellular Towers Map). The only frequencies in Kelowna are 850 and 1900 actually.
This being said, shouldn't the Galaxy S III work in my area if I were to continue with my pre-order for the International variant?
[EDIT]
Also, just to point out, the HTC One S, which is also just released on TELUS, also opperates on the same frequencies as the Galaxy S III International.
I think you'll be fine.
And if the international version doesn't work from wherever you buy it from, I'm sure you can return it.
That's the premise I'm going on with SaskTel.
@MaesterB: Yeah I think so too. I spoke with a TELUS rep now and he claims that the 850/1900 MHz frequencies are enough to handle up to 42Mbps download speeds, and the 1700 MHz is primarily for the LTE coverage areas (Vancouver, Toronto, etc). Of course, in my area my Galaxy S II can only hit up to 6-8 Mbps anyways so I'm not overly concerned.
Exactly.
In Regina, we have "4G" but the fastest I can get is like up to 5MB anywhere in the city.
So, the International SGS3, running on 3g/4g...should be just fine.
This is a technical question and even though it's about the t-mobile t999 I decided to post it here as well because the post relates to the international version as well. Here it is:
I live in Israel. I used to live in the US. Last time I was in the US I bought this phone and brought it over. I did my research beforehand and knowingly purchased the phone assuming I would have full compatible with Israeli service providers...
Now, I'm not so sure anymore. I just tried the phone today.. maybe 5 hours of use. Still have the default OS installed. No root or anything. The signal seems to fluctuate going between Edge and higher speed networks.
Here's what it says about Cellcom on wikipedia:
Cellcom eventually sought to replace the 850 MHz TDMA frequencies it owns with standard 900 MHz GSM frequencies but Pelephone and Partner (Orange) petitioned the Ministry of Communications to deny this for technical reasons. This put Cellcom at a disadvantage since though most of its users had converted to GSM, they were not able to make use of the lower frequency's better in-building penetration and greater cell reach.
With its entry into 3G wireless services Cellcom demoed the first mobile video call in Israel. Since the beginning of 2006, Cellcom began deploying a 3G UMTS-2100 network nationwide which by the end of 2007 covered than 87% of the population. Cellcom was the first in Israel to launch an HSDPA network (also called "Generation 3.5") nationwide. In 2011, Cellcom began to deploy UMTS services in the 850 MHz band, employing unused capacity in that frequency range since it had very few TDMA customers remaining. The Israeli Ministry of Communications has approved Cellcom's plan to shut down the TDMA-850 network on 31 December 2011.

I just put the SIM card back in my old international Galaxy 2 i9100T and it'll fluctuate between HSDPA: 8 and HSPA+:15. Also it displays an H icon in the status bar (I don't think Resurrection rom is capable of displaying an H+).
Anyway, I'm going to put the SIM back in the Galaxy 3 t999. It now fluctuates between EDGE: 2, HSPAP: 15, HSPA: 11, and UMTS: 3. The signal is shifty and only displays a 3G at the top, no H like the international Galaxy 2.
Here's what wikipedia lists as the differences between the two models of the Galaxy 3 (standard international i9300 and my t-mobile t999):
Model GT-I9300;
2G networks: 850, 900, 1,800, 1,900 MHz GSM / GPRS / EDGE

It could be an OS issue. Have you tried flashing yet?
You will never get an H or H+ with a T-Mobile branded GS3. It's as simple as looking at your User Manual.

Your phone contains all the networks for Israel, but it's optimized for T-Mobile's network. So you aren't going to get the performance you would get with the International GSIII.
Hi guys, some super important info here, For anyone considering getting the international version should CONSIDER getting the T-mobile phone instead because it can utilize future LTE channel 700MHZ worldwide: (Assuming this is correct)

Now with this information above,
I noticed the only difference between T-mobile's Samsung Galaxy S5 (G900T), and the international Version (G900F) Is that the LTE 700MHZ is missing from the international version.
This brings 2 important questions for BOTH users of both phones.
1. Now, Assuming the specs are correct on the G900T, (it appears to have future compatibility with 700MHZ being released by Tmobile, and other networks worldwide in 2014-2015.) We need to know if this is indeed correct or not.
2. I had flashed AllianceROM for the international version on my G900T, and it shows G900F in the about device.
Will this prevent any phone flashed in this manner from using 700 MHZ if the ROM is a G900F and flashed on a G900T. This is not important now, but will be very much so in the future as the cellular networks mature and roll out the AWS LTE band 700.
This is SUPER important as it may cause headaches for developers/users and mass confusion in the future if the issue isn't caught now before everyone starts using LTE 700 (AWS), and projects mature, and users may notice coverage gaps, if (2) above is confirmed to be a problem.

Fair enough, however we need to get confirmation if the international ROM's are compatible and can utilize the 700 MHz LTE band (radio) on the G900T regardless of model displayed on the phone. I would think it *might* work, but without 700MHz available yet on T-mobile, I can't test it.
Doesn't matter what ROM you installed ... If you actual phone has LTE bands than it wouldn't really matter what ROM you installed .... and like the other guy posted you can edit build.prop and make it to any model you want ...

Your answer is yes, just know when flashing a int rom, apn settings are for other bands. When I flashed alliance, I had to change apn settings to the LTE version. I know this for a fact cause I have 2 s5's and I had to copy its original settings to get LTE speeds

That's not the only difference:
T-Mobile (T) has LTE 700 & 1700 (Band 17/4), International version (F) does not. (mainly used in North America)
F has LTE 800 (Band 20), T does not. (mainly used in Europe)
F - WCDMA 850/900/1900/2100
T - WCDMA 850/1700&2100/1900/2100
I'm in Hong Kong where they sell unlocked F version but I travel to the US (and Europe) very often (have a place there) so I'm waiting to get a T-Mo version - which IMHO has the best world wide LTE coverage.
I am confused and would very much appreciate if someone here who knows this stuff clear it out. According to these sites the T-Mobile 700 MHz block will be band 12 and the SM-G900T has band 17 which is a subset of band 12.
http://en.wikipedia.org/wiki/T-Mobile_US
http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
So it seems to me that while our phones might be able to get on some 700 MHz LTE networks they would not be able to use the USA T-Mobile 700 MHz band?
Edit: Just found this:
"Annoyingly, both the AT&T and T-Mobile (SGS5) models lack LTE Band 12, which T-Mobile and some regional carriers are implementing at the end of this year to improve rural coverage, but no other phone has that yet, either."

More than likely, No.
Based on what I've read in other articles there is "physical" gap between the bands on 700mhz which requires filters on the PCB.
The S5 would have had to be shipped band 12 capable from the start or the hardware would have to be refreshed later in the year.
If the GS5 were band 12 capable you'd think they would try to market it as such, since that would be a major upsell.
I wouldn't hold my breath for a hardware refresh though. Seeing as the carriers (especially T-Mobile) seem to have a "hard time" trying to stock multiple internal storage and color options as it is, throw band 12 capable" and "not band 12 capable" and the whole system might collapse!
Old topic ?
Flash an international S5 rom then flash a t-mobile radio.

fffft said:
I'd say more than likely, yes.
Your information about SAW filters being necessary is out of date. The S5 has been reported to use the Qualcomm WTR1625L RF transceiver. This chipset is capable of operating on all LTE bands.
There may still be cost saving or protectionist measures in supporting hardware choices that limit us but given the available evidence, the overwhelming chances are that each variant can access an arbritrary set of LTE frequences and that the restrictions will be firmware based.

I stand corrected if that's the chipset used. I knew Samsung had been using SDRs I just was not aware that chips had become available to also dynamically handle the filtering.
Here's hoping it gets resubmitted to the FCC for band 12 approval later this year.

Chipworks says that is the chipset and they should certainly know. The WTR1625L is release 10 compliant so it supports all 34 announced bands, not just the current bands in use. The companion WFR1620 chip in the photo is used for carrier aggregation which is LTE channel bonding to achieve higher speeds. Interestingly, Qualcomm's aggressive release schedule already puts a 28 nm successor on the table, the WTR3925 which will be the first single chip carrier aggregation solution to market. It will be release 11 compliant.
The move away from discrete filtering and aggressive push towards single IC systems is meant to capture a larger market share in this multi billion dollar market. Single chip solutions can hit cost and power reduction goals that discrete components could not reach.
The wild card, the possible hardware bottleneck will be the Avago RF front end. It's rumoured to be release 10 compliant as well, but since Avago only releases their specs and datasheets to qualified customers we can't be certain yet.

Gentlemen, all phones operating in full duplex mode require band-specific RF duplexers to separate the uplink and downlink frequencies and route the antenna to and from the receiver and transmit PA respectively. These are essentially paired RF filters. Duplexers serve the additional purpose of blocking out of band interferers including harmonics generated by the phone transmitting on other bands. Additional SAW and BAW filters are still required in the receive chain in some cases to block interference as well.
E-UTRA bands 1 through 32 are FDD bands and require duplexers. B12 requires its own duplexer. A tunable duplexer that can operate over several of the 700 MHz E-UTRA bands might be possible in the future, but for now a phone that can operate in LTE mode on AT&T (B17), Verizon (B13), US Cellular etc.(B12) requires multiple duplexers.
A phone operating in "All LTE bands" would require an unworkable number of duplexers. As a result, LTE phones are operator and region specific with respect to LTE, and right now it takes at least three SKUs to cover the main population regions and LTE operators across the world. The radio chipset is the same, but not the duplexers and usually not the RF power amps. Some phones will not operate on the right frequencies for LTE on some carrier networks without hardware changes.

Thanks for the response.
When I google the WTR1625L the results I'm seeing are claiming it is Release 10 based and supports all announced bands. Maybe their wording is over simplifying but it seems to imply it's capable of handling the duplexing, antenna switching and basic filtering as one combined chipset.
I understand that there could still be a possibility of needing additional interference filtering.
Are you pointing out that the WTR1625L really only has selective support based on how the OEM builds out the chipset?
ie. Hardware wise (ignoring software configuration), if the OEM using the WTR1625L gets a request to not include (or doesn't ask for) a specific band they wont actually physically assemble it in a way that supports all bands.
Edit: here's a link to the press release from when the WTR1625L was announced.

The observations about discrete components being a limiting factor was accurate five years ago. It largely out of date now and specifically has little relevance to the specific chipset under discussion. This chipset is release 10 compliant and only requires minimal external hardware support.
A RF front end is still required, but as the current generation of Avago chips have made comparable advances and are also R10 compliant. The days when we needed a slew of SAW filters and other discrete components are behind us.
Between that and general manufacturing practice, it is all but certain that the in situ chipset can support all existing GSM and LTE bands. The (artificial) restrictions will be in the firmware.

Any new thoughts or information on this discussion?
Is this device compatible with AT&T network? Or is it just not compatible with the 5G network?
These are the bands the phone has. So it should work just fine on att and tmobile (plus all the sub carriers from these two)

Thanks for the info. This is a relief. I want a headphone jack and SD slot. Very hard to find.
Read this, which is consistent with what I had previously read. No mention of ATT 5G for US version. Hoping @cyanpac is correct:
"Buyers of the North American model of the Xperia 1 III will be restricted to the black edition that comes with 256 GB storage. The smartphone delivers dual-SIM capability and is reportedly compatible with the 5G networks in the US offered by the carriers T-Mobile and Verizon."
Official Sony Xperia 1 III price in the US leaves potential buyers wondering about pre-order bundles to soften the blow
Sony has finally revealed the asking price for the Xperia 1 III in the US. The 5G-capable smartphone with triple lens camera, water-resistance certification, 4K 120 Hz OLED, and even a 3.5 mm audio jack, will set buyers back by US$1,299.99. Plenty considering a purchase have been speculating on...

It is more compatible with TMobile and Verizon because it has the bands they use. It barely has 5g bands and barley any 4g bands for att. It'll work but you'll have signal issues most likely. TMobile is pretty cheap and the service they have now is miles better than what it was even 3 years ago.

Well, I need/want a phone with headphone jack and SD slot, which are hard to come by, so I guess I'm going to have to switch to T-Mobile.
I spoke with a guy at B&H Photo, who are taking pre-orders. We had a long conversation about the bands. His view is ATT will be about the same as T-Mobile for 5G coverage based on what he could see of T-Mobile's 5G bands. I pre-ordered and will give it a try on ATT. I can always move to T-Mobile if I'm not happy with how it runs on ATT>
Does anyone really make their phone decisions based on 5G bands? That technology is honestly still a few years off being actually useful unless you're parked under a 5G tower

How is being parked under a 5g tower magically going create apps or tech that takes advantage of 5g?
I thought the Xperia could connect to the 5G bands that actually will increase connection speed drastically: n41, n71, n77, and n78. I do not value the mmwave 5G because they drastically drain battery.
11 frequencies are used in N.A.
Checkmarks added for Xperia III U.S. market capabilities.
X n2 (1900 PCS)
✓ n5 (850)
X n12 (700)
X n25 (1900)
✓ n41 (2500)
✓ n66 (1700)
✓ n71 (600)
✓ n77 (3700 MHz) used for C-band
✓ n78 (3500) used for C-band
X n260 mmWave (39GHz)
X n261 mmWave (28GHz)
Extra info:
13 frequencies are used internationally:
n1 (2100) Britain
n3 (1800) Germany
n7 (2600) Thailand
*n8 (900) China?
n20 (800) Australia
n28a (700) France
n38 (2600) Thailand
n40 (2300) Australia
n66 (2800) Kuwait
n79 (China)
*n258 mmWave(26 GHz) Australia
Same as N.A.: n41 (2500), n77 (3700 MHz) used for C-band, n78 (3500) used for C-band
Possible that n8 (900) is used in U.S. in future?
*not supported on iphone 12. Iphone 12 has the most 5G connectivity capabilities. I researched where all the bands supported are used.

B&H Photo, the best.
Only issue with 5G coverage is it's coverage even when there are plenty of 5G towers. It's more directional than 4G.
Perhaps the rep is correct though, their staff tends to be very knowledgeable. AT&T is a monster anyway

Thanks. I look forward to your experience
Hate to break it to you but we will only be able to get 4G LTE with HD Voice. This is extremely agrevating as I purchased the Xperia Pro to take advantage of the 'extraorinary' 5G speeds but turns out the phone only gets 4G LTE + HD Voice. IMEI gets picked up by AT&T as the Xperia Pro and even with a APN changed it refuses to connect.
Since the phone is unlocked, couldn't you get it on AT&T and if the 5g coverage didn't work well, just switch over to TMobile?
When ordering you have to pick carrier, my guess is that they include a SIM for that carrier? but you could just swap to another carrier SIM if you wanted later?

5G speeds tend to not be so extraordinary. Up to a 20% increase over 4G LTE if you're within range which is also iffy. That's what I've been seeing reported.
I wouldn't sweat it...
Just spent a few hours w/ T-Mobile Expert Tech and Xperia USA Tech after trying everything to access T-M's 5G n41 band with my 1 III (XQ-BC72). Short answer: it's not happening and neither rep knew why so they're submitting a ticket and will get back to me.
For what it's worth - although the "Expert" reps would neither deny nor confirm, when I called Xperia Support USA (855-806-8464), the tech rep there said she found a Sony bulletin which said only Verizon 5G is working currently and T-Mo and AT&T will be fixed in a software update - no ETA.

No Volte and no wifi calling on Sony too (its terrrrrrrible)
The Xperia 1 III US model doesn't support 5G very well. It's unreliable even on T-Mobile because stand alone mode is disabled in the phone's configuration. It combines a short-range LTE band with long-range NR 71. Being that SA is disabled, it gains nothing but battery drain from that mix.
