AT&T labels HSPA/HSPA+ as 4G and LTE as 4G LTE. T-Mobile does the similar thing. In other places, HSPA+ is called 3G and LTE is called 4G. Semantics. HSPA+ is based on UMTS.

VoLTE has to be enabled in the phone's firmware. When the time comes, AT&T will release a firmware update to enable it as it did with short list of other phones that supports VoLTE.
[Samsung Galaxy Alpha] CashmereEsquire:
I see this is on Ebay right now for a good price, I assume this will work 100% on cricket wireless with LTE? Are there various model #s? On Ebay it just unlocked. I wanted to get this to use for work.
[Samsung Galaxy Alpha] robertkoa:
Interesting .

I am not a dev but as I recall Metro PCS was

one of the first to have VoLTE and also simultaneous Voice and Data back on 2011 or 2012 so I was used to talking on calls and always seeing 4G LTE on the phone. LG Motion 4G.

So this Alpha is my first Samsung- and my first factory unlocked phone still on Metro Tmo.

Now I see the LTE drop to 3G when I make a call but thanks to better APN Settings I almost always have voice and Internet simultaneously because the phone jumps to H or H+ and gives fast Internet on a call on H+.

I even had Youtube and a Speakerphone call a few times as silly experiment.

I also with inferior APN setting got "unable

to access Internet while on a call message"

previously so APN Settings make a big difference sometimes.

Very few problems, fast phone, good audio and sharp Camera...

Hope that Samsung has a Note 5 with removable battery and does a Compact Note kind of like super Alpha..

Not sure if Lollipop will give VoLTE to a Factory Unlocked Phone but if any Devs can achieve it for me ...good Donation .
[Samsung Galaxy Alpha] anosis:
There is a G850M and a G850F which both are international unlocked phones but cover different LTE bands. I would recommend that you check your carriers available bands (this is also depended on area), then cross check this with http://www.gsmarena.com/samsung_galaxy_alpha-6573.php

There are a few variants specifically for the asian market, but unless you live there you will have a difficult time in the US to get them.
[Samsung Galaxy Alpha] gagdude:
When your G850M boots up, does it display any carrier branding?
[Samsung Galaxy Alpha] bormasina:
All sources that i could find on net say that SM-G850M doesn't support the band 4 on WCDMA/UMTS. They may be wrong. Since you own the device you would be the best source whether band 4 is unlocked on the device or not. I mention band 4 because that is the band t-mobile uses in most markets on 3G (fake 4G) and LTE. Go into settings\more networks\mobile networks and change the preferred network connection into 3G (or it may say 4G on your phone, just stay away from LTE), verify that it is now operating on 3G (fake 4G), then go to dialer and dial *#197328640#, choose "BASIC INFORMATION' and report what you see. I own the ATT version and when i force it (using *#*#INFO#*#*) into fake 4G it reports "RRC:IDLE, BAND:5" which is WCDMA BAND 850, that is what ATT uses here (ATT uses BAND 2 here also which is WCDMA 1900) where i live for 3G (fake 4G). When i switch back to LTE and go into this hidden menu, it reports that it is connected on "LTE RRC:IDLE BAND: 17", which is what ATT uses in my area. So you may be in market that t-mobiles uses PCS band for 3G (BAND 2) and that would explain why you do not drop on EDGE. It would be a lot clearer when you report properly on which BAND you are connected. What is concerning is that you say you loose data when making calls, which makes me think that you indeed drop to EDGE while on calls, which is painfully slow and makes you think you lost data. As i said, it would be easier to understand what is going on when you provide the whole picture ...

This is what i know that t-mobile uses on 3G:

-- BAND2 and BAND4

and LTE:

-- BAND4 and BAND17 (they might be using BAND2 too in some markets)
[Samsung Galaxy Alpha] foxbat121:
If your phone drops to EDGE, you won't be able to do voice and data simultaneously. You need to be on 3G (UMTS minimum) to have simultaneous voice and data.

Since Alpha only has AT&T version released in US, I'd suspect you can't buy any model of Alpha that fully supports all T-Mobile's bands because of the unique mix of bands used by T-Mobile.

The models sold on ebay varies a lot but the one I purchased says Factory unlocked by also states AT&T compatible. For all intents and purposes, the one I received is actually AT&T version, indeed factory unlocked, running AT&T branded firmware. That fits me just fine because I'm on AT&T. But if you are not on AT&T, YMMV. Cricket wireless, IIRC, is now a subsidiary of AT&T.
[Samsung Galaxy Alpha] Corvussimo:
OK, I did this: I changed the settings on my G850M to force 3G. The code(s) you said to put in didn't work for me, so I used *#0011# instead. It said two different things, depending on when I did the test. Once it said 1900 Band 2, and once it said 1700 Band 4. Then, I put it back to LTE and it said Band 4. I've attached screenshots of all three. This is T-Mobile in Portland, OR.

Also, I found one reasonably reliable Internet source that indicated the G850M does support 3G Band 4. Here's the link:

Samsung Peru's Specs on the G850M

I was also hesitant to buy the G850M for the same Band 4 reason, until I found the specs on the Samsung Peru Website. The screenshot below shows that the M indeed does have 3G Band 4.
[Samsung Galaxy Alpha] bormasina:
Thanks for doing this. It is always good when things get confirmed like this. Now I can safely purchase one for wife. Where did you purchase it, if I may ask?
[Samsung Galaxy Alpha] Corvussimo:
Glad to help. I was a still a little concerned myself until I ran this test.

I bought it on eBay from The Pwrsellers

They currently have black, white, and gold for $450. Mine was a Brand New Open Box black model, so it was another $50 less than that. So far, so good! There is no cell company boot-up screen, and the bloatware is at a refreshing minimum.
[Samsung Galaxy Alpha] foxbat121:
AT&T now sells brand new for $319.99 retail.
[Samsung Galaxy Alpha] jjsaustin:
I was at att last weekend and they wanted like $600 to buy it the 850a.

I got the 850m from target online via Amazon. It does work on t mobile.
[Samsung Galaxy Alpha] Corvussimo:
Yeah, I almost bought one from Target, too, but this less expensive one came up just at the right time. FWIW, the one I bought from The Pwrsellers came drop-shipped from Amazon as well, so that makes me think most (if not all) the companies selling the G850M in the US right now are drop-shipping through Amazon.
[Samsung Galaxy Alpha] jjsaustin:
I bought from target for the return policy, especially since I was not sure if it was going to work on tmobile .

I just bought another one to see if the reception is any better and I will return the one with the worse reception.
[Samsung Galaxy Alpha] robertkoa:
Thanks for 1700 Band Test on 3G

I have found APN Settings for Metro/Tmo important for best performance on my Factory Unlocked 850M.

MetroPCS frequently uses Tmo APNs even on Metro PCS Phones.

With Factory Unlocked Phones I assume trial and error may be best for an advanced Phone like Alpha.

I tried the Settings used for Note 4 on Tmobile which worked but not as well as what I use now but open for suggestions lol.

Here are current best I have found which are fast Data and allow

Internet while on calls about 90% of the time.

I always have good voice and audio on calls.

Here's current APN Settings :View attachment 3210457

View attachment 3210458

I have found that IPv4/IPv6 seems to perform a bit better than IPv4 .

But I have NO IDEA what these do in Tmobile Protocol.

Also I leave BEARER unspecified but have tried LTE also.

The only problem I sometimes have is no data on 3G and Phone does not bounce back to LTE AFTER a call- often turning data off and on with Quick Toggle restores LTE quickly.

Oddly this is an intermittent problem.

Often I have quick Internet while on a call but sometimes no Internet on a Call.

Here are the screenshots from my Alpha 850M which has no Carrier Branding when I forced 3G also some H showed and I got

1900 band in 3G but have not seen 1700 3G but in LTE in second screen.

I am in Miami area which is reframed so Metro/Tmo uses 1900 more here for 3G - Corvussimo - how did you get 1700 to show on 3G - is yours a Factory Unlocked unbranded Alpha ?

Thanks for both your help very interesting stuff.
[Samsung Galaxy Alpha] Corvussimo:
I haven't had your problem of no data on 3G during calls, but I did have an issue with some intermittent undelivered texts, once on my 850A and a number of times on my 850M. The APN Protocol was set to IvP4, so I switched it to IvP6 (which is how it is on my reliable but sluggish, cheap, clunky, amazingly boring Galaxy Avant), and that seems to have taken care of the problem. As a precaution, I've toggled on SMS Delivery Reports.
[Samsung Galaxy Alpha] Corvussimo:
Yeah, mine is one of the factory unlocked G850M models that are being sold on eBay. I just forced it to 3G by toggling Mobile Networks to WCDMA Only. Last time it took a try or two dialing *#0011# to get Band 4 to come up. I ran the test again tonight and Band 4 came right up. Then it switched to Band 2 right as I was looking at it. Then it went back to Band 4 and stayed that way for a really long time, basically until I put it back to LTE. Just at the last minute, right before it went back to LTE, it went back to Band 2. Got a screenshot of that, too. This is T-Mobile up in Portland. Go figure.
[Samsung Galaxy Alpha] robertkoa:
Thanks Corvussimo.

Just to be clear- on my Alpha if it shows LTE on the Display- as soon as I make a call the display shows 3G and sometimes H .

Is your Alpha also this way ?

Native Tmo and Metro Phones can make calls while in LTE .

Also what are your Data Speeds like.

Mine are very inconsistent....
[Samsung Galaxy Alpha] Corvussimo:
Yes my Alpha is the same. As soon as I make a call, it drops to 3G. Foxbat mentioned in another post that the Alpha can do VoLTE but the firmware doesn't have the feature yet. Maybe soon... I really want WiFi calling on this Alpha, too.

Here are two speed test results. The first one is the server closest to my house (Comcast, 4mi away), and the second one is the closest T-Mobile server (157mi away). I get pretty good speeds here--certainly good enough for what I need--and for the most part the speeds seem reasonably consistent.
[Samsung Galaxy Alpha] robertkoa:
Thanks very much To Corvussimo and Foxbat 21.

I was playing with IPv4 IPv4 Ipv6 and

IPv6 settings but now found a better main APN with metropcs setting and others for TMobile.

I DEFINITELY have re- confirmed the 3G band 4

1700 using same steps as Covussimo and am getting more stable LTE and quicker " handoffs " back to LTE as soon as I end a Call.

Also when I am on a call it says 3G but when I go on Internet DURING a call it jumps to H+ or H for faster Data and I have Data on calls always now so far.

Never any problems with text or mms.

Odd that Samsung does not list 1700 Band 4 on 3G - definitely there like Corvussimo said.

I switched to a hybrid APN crossed between Metro PCS and Tmo since I am on Metro PCS but APNs are ( kind of ) interchangeable

So NOW I saw the mysterious 1700 CDMA frequency on 3G during weak signal!

So we have all the LTE Bands including the new 700 frequency for future use by TMo.

And on 3G we have on 850M the 1900 band AND 1700 3G band for solid 3G H and H+.

APNs including IPv4 IPv4- IPv6 IPv6 can be important as can other settings.

Alpha locks onto weak signal in elevators well etc.

An excellent phone with Note 4 Camera and bigger battery would have been GREAT PHONE.

Hoping for Note 5 Compact but probably won't happen.

Also hoping for Pro Line phones that can be

THICKER with non protruding PRO Cameras and big batteries in Future.

This stylish thin fad to 6mm thin phones is greatly limiting Design/Performance.
[Samsung Galaxy Alpha] Corvussimo:
robertkoa, What APN and settings are you using? I'd like to try it here in Portland. Always looking for more reliability.

The T-Mobile signal strength where I live is not very good (-110 dBm). There is another company--probably Verizon--that has a much stronger signal in my neighborhood. I've never dropped a call, but it would be nice to have more signal strength.

I noticed that all of Samsung's Latin American Websites show the G850M, with all specs, including frequencies. Band 4--also called AWS--1700MHz is listed in the specs. None of the European, Middle Eastern, and Asian Websites even show the 850M. They feature other models, W, Y, F, which do not have 3G Band 4 (AWS).

I would LOVE a Note 5 Mini. Best of all worlds. Bought a Note Pro (12.2) last month, and it ROCKS. Now, of course, I want a cell-phone size one with all the awesomeness of the S-Pen
[Samsung Galaxy Alpha] robertkoa:
Here are the APN Settings and the Band 4 1700 also known as

AWS also known as 1700/2100 - I really think they should have

4 or 5 more names for UMTS Band 4 to make it even more ambiguous and confusing - lol.

Edit ALSO known as WCDMA Band 4.

ALSO known as UMTS Band 4.

How about WTF Band for another name as in " What The F***".

Last night at a high rise Hotel my Alpha was on H+ for a long time while I had Tune In Internet Radio on and it was on the

1700 Band.

I think that I am seeing this Band more often now because of the

new Hybrid APN and it is why I am getting better performance.

Tmobile says they are using 1900 for 3G in Miami as a "Reframed"

area- but it is obviously better to have Band 4 AND 1900 Band.

I was able to receive Tune In all the way down the elevator and in the Parking Garage.

Most phones can't make calls in the Elevator but Note 4 can and Alpha-there are similarities in the Radios.

The reason I want a Note 5 Compact is not the Stylus- It's that the Camera on Note 4 is so sharp and detailed.

I did a Mall Shootout between an Alpha, S5 , Xperia Z3 Compact and my friend' s Note 4 and the sharpest was Note 4 .

I say Mall Shootout because I was just shooting at AT@T and the Sony Store back when I was considering Z3 Compact.

This PARTICULAR Z3C beat the Alpha and S5 for sharpness and detail BUT quality control on Camera and Speakers and fragility of Z3C scared me away so Alpha was my choice but

Note 4 won by far.

Recent shootout of S6 and Iphone6 and S5 and Note 4 and Note 4 still sharpest ( same sensor as S6 with narrower aperture) and you can see ( GSM Arena Shootout) that Note 4 still sharper than S6 - S6 wins low light.

Protruding Camera on S6 is fairly easy to break Glass. Happened on another Pro Review.

Also is your speaker louder/ fuller on the 850 M versus the 850 A ?

Mine is much fuller that AT&T versions which were decent volume but tinny no midrange .

You can check your IPv6 settings compatibilty on a what is my

IPv6 Site by Tmo I will find a Link.

But you might want to try IPv4 IPv6 - the " Both" Setting.

Still for weak signal you have very good speeds.
[Samsung Galaxy Alpha] Corvussimo:
I was at the Dallas/Ft. Worth Airport today, I got a LOT of 3G and H+, ALL Band 4 (1700). Just to make sure it wasn't the phone, I tried my Avant as well, and got the same thing. (I bring the Avant along and pop my SIM card into it when I fly, so as to use the free texting via wifi calling feature, available to T-Mobile customers through Gogo Inflight. That's why I wish the Alpha had wifi calling.)

Yes, noticeably fuller on the 850M than on the 850A, with better clarity and quality. I got rid of my 850A; sold it on eBay.

I just changed mine to the "Both" setting. I'll let you know if I notice a difference. Thanks for the info!
[Samsung Galaxy Alpha] robertc88:
Hello,

I'm currently on tMobile with 3 gigs of data.

Is this the variant you folks are writing about? I'm interested because it is lots cheaper than the s6 and isn't going to have the bloat that one does and I'm sure memory management will be better as well.

http://www.amazon.com/Samsung-G850M...65&sr=1-2&keywords=samsung+galaxy+alpha+g850m

Thanks much for your help.
[Samsung Galaxy Alpha] robertkoa:
Yes the 850M Factory Unlocked Version is the one we are talking about.

Very good for Tmobile/MetroPCS because it has the LTE Bands including the future 700 band for better reception through buildings.

And surprisingly has the Bands for 3G H and H+.( including 1700 which they don't list and 1900 which they do list)

Excellent loud clear speakerphone , and clear calling even in low signal areas.

What you will NOT get is VoLTE like you get on a Metro PCS or Tmobile branded Phone.

Reviewers talk about call fidelity with VoLTE but IMO they are missing the point.

On Metro/ Tmo Branded Devices when you make a call you stay on LTE and still have fast Data/Internet.

On factory unlocked Devices, even excellent ones like this Alpha 850M you drop to 3G or H or H+ but with proper APNs you can still get H+ while on calls and fast Internet simultaneously.

S6 will give you higher res screen (I don't care about that) longer battery life (unless you get 2500 battery for Alpha) and is maybe faster at larger file handling.

Big advantage of S6 is better Camera if you need it ..Alpha Camera is a shade lower res than S5 same large Sensor clocked down to

12 megapixels .

But the Alpha especially this Exynos 850M is an excellent little phone with great audio.

So if you can get one at $350 to $400 should be a great deal .

Samsung SHOULD have put two of these exact speakers ( from 850M) on the S6 and they would have been near or equal to

HTC One M8 ..
[Samsung Galaxy Alpha] robertc88:
Thank you for the feedback.

With the S6 so close to demo at Best Buy, I will look at it first. Unless it completely blows me away, I will opt for the Alpha. Time will tell.
[Samsung Galaxy Alpha] robertkoa:
Lol. Time will tell for me too.

IF the Speaker is as good as this Alpha and the Battery lasts pretty long I may upgrade to S6 at some point because of the excellent Camera.

S6 is not as nice a size as Alpha but looks pretty solid- like Alpha Samsung made S6 too thin but S6 is nice and fast and customizable and the Camera....is gonna be wow.
[Samsung Galaxy Alpha] coolkev99:
850m vs 850a vs.....

A little late to this tread... this is pretty much the ONLY place on the internet discussing this topic in detail. I too am looking to get an Alpha for T-Mobile, but was massively confused on what variant to get. Reading though here has helped, but I am a little unsure what the real differences (besides CPU) are between the 850m and 850a(AT&T) models. Will they both connect equally well to T-mobile networks with all supported bands, or is the 850m model clearly better? I ask because the 850a model can be found for quite a bit cheaper. However I am not willing to give up connectivity, so if I must pay more I will.

Also any word on pros/cons of the Exynos CPU vs Snapdragon? I would guess similar performance, but what about battery life?? Alpha doesn't exactly have a huge battery.

You all have been a BIG help :good:

---------- Post added at 03:25 PM ---------- Previous post was at 03:15 PM ----------

Hi Corvussimo. Are those screen shots 3G (fake 4G) or your LTE 4G speed? Looking to get an Alpha for T-mobile... Thanks! :good:
[Samsung Galaxy Alpha] foxbat121:
From what I read from the specs, both support the same LTE bands. I could be wrong but I saw T-Mobile also uses band 12 in some places. Neither model supports band 12.

[Galaxy Note 4 Accessories] DimeDrl:
I'm looking for a rather specific accessory. I use a generic holster with a stand case. This one specifically.

http://smile.amazon.com/gp/product/B00OIL30YA/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

I want to extend my battery life, but still retain the holster. I've looked at all the extended battery threads here and found that most of the batteries have a completely useless rounded replacement backplate that makes a holster unusable, and that the Zerolemon battery has issues with the phone's battery reader.

Based on this, I'm looking for a battery case with holster. It just seems like a better solution to the issue. I'm looking for something like this:

http://smile.amazon.com/PowerBear®-...424651599&sr=1-1&keywords=Note+4+battery+case
