Things to expect when using at&t alpha on T-Mobile? - Samsung Galaxy Alpha

Hey guys, I'm considering getting an at&t alpha, to use with my T-Mobile Sim. Does anyone else here do the same? Will this affect my reception? I have heard my LTE may not be as strong. Also, will this affect how I get updates? Is there a difference in speed from the exynos and snapdragon? Thanks!!!

I am using it now on T-mobile network.
Hotspot will not work unless you root it. You cant root ATT phone. Wifi calling will not work. I dont use any of it.
I did speedtest on this phone and on my Tmo Note 4 and the 4G LTE speed are almost the same.
To get it to LP 5.0.2, you need a ATT nano sim card. I heard you walk into the store n buy or it or some store even give it to you free. Or you can buy from fleabay. I am happy just staying on KK 4.4.4

So do I need it to have service? Or can I just use a blank Sim and download over WiFi? Also, how noticeable is the difference in texture between the white and black mode?

Do not go for the AT&t Model because
1) you need at&t sim to update.
2) There is no work around for this.\
3) There is NO ROOT for the AT&T model and might never be....as its not supported by developers.
4) Even if you get an at&t sim from someone and update it things might get broken as some users have reported "recent key" not working after the update and since its bootloader locked there is no way users can downgrade it Via odin (just to mention because its bootloader locked there are no firmwares on sammobile either).
5) at&t has a snapdragon processor, while the 850F model has exynos 5430 which is about 30% more power efficient than the snapdragon one.
6) Do yourself a favor and buy international, factory unlocked SM-G850F Model. Hope it helped

if I don't want root but want better lte speeds with t-mobile would the 850m with same band support as att alpha but ezynos processor be a better option?

i don't use LTE so can not guide you on that but if we put the LTE aside ... think about it there are so many at&t alpha users complaining about their RECENT BUTTON not working after 5.0 update. There is no way to downgrade....they are stuck with unusable devices....however some 850F users who experienced the same problem downgraded with ease....i think 850F is much better.

Yeah you need to have a working at&t sim to get updates. and Yes the unlocked version is worth every penny cuz of root,customization and exynos 5430.

This is the route I went. I still want to use att LTE and be able to root my device. Best buy had a deal a couple of weeks ago. G850m for $349 usd unlocked, bought it right away. I believe price has gone up since though.

Is your 850M on Tmo getting fast data speeds on Tmobile.
To OP - I just got a software update OTA direct from Samsung by selecting software update on phone on Metro PCS - neither Metro nor Tmo carry the Alpha so it upgraded direct from Samsung to 850MUBUBOB1 software version.

Thanks guys. I definitely want the unlocked model, but considering I have a nexus 5, I dont feel like I need to have the latest software all of the time, especially touchwiz. Is there a difference in texture between the white and black phones?

Yeah, G850m has root and custom recovery as well. Some roms available but not a lot. I wouldn't want to update with root and trwp if I were you, it might cause some issues.

Are you saying do not update to LP 5.0.2 ?
I am still on KK 4.4.4 on this ATT phone unlock n using it on T-mobile network. So far I am loving it.

I have used G850A on T-Mobile network. It works great and the LTE speed is much faster than on AT&T. I could get the lollipop update using an old NET10 SIM card - the network was reported as AT&T. It's much better than with Kitkat. I switched to Cricket, which uses AT&T network but is reported as cricket instead of AT&T. The coverage is better, but with slower LTE. No problem with the recent button.

Hello, the root instructions for the G850m is the same as the G850f. They are both the exynos cpu. The thread I believe is in the q&a section.

Some people complain about the recent button not working after lollipop update. A bonus comes with lollipop on T-Mobile - free tethering, which is not available on AT&T.

Should I buy the international version or AT&T ? noob questions :)

Hey guys,
I have pre ordered the S3 ( AT&T) version and I will be using it in Canada, now I am not sure if I should cancel my preorder and buy the international version or stick with AT&T unlocked one, I bought it because it does support LTE but at the moment Fido doesn't support LTE ( they said they will this year).
I am worried about the battery life since I read that LTE eats the battery, can I disable LTE? Also what about firmware updates since I am in another country and the phone is for AT&T, would I be able to upgrade to the latest once they release it and how?
I have never used android before and I don't know alot about phone so my questions might be noobish

I don't think the AT&T version is unlocked. I think it is locked to that carrier and you can only use it on AT&T. I suggest you get the international version.

Unlock Frequencies

As posted here: http://forum.xda-developers.com/showthread.php?t=2188467
Do you guys think the devs will be able to enable AWS HSPA bands on the ATT / Rogers / Bell / TELUS devices?
Many of us in Canada use Roam Mobility (T-Mo MVNO) when we roam in the USA. Having access to AWS + 1900 HSPA would be great so that we're camping on 2G less often.
It is in there, the problem is unlocking it. ATT may have required an efuse based lock that cannot be changed once set at the factory.

Interesting thing is htc has listed data speeds for canadian version via hsdpa is up to 42mb and it's the same for t-mobile USA, only At&t has different one. This could mean, that Canadian version might be similar to T-mobile version. But, this could just mean at&t's network doesn't support speeds of 42mb on hsdpa. I'm leaning toward network limitations.. But, I'm hoping I'm wrong haha

That's great, but Samsung's lock was superficial, incredibly easy to bypass. Maybe flashing TMOUS radios will do it, but there's no guarantees and it requires S-OFF.

We know, but the hack or mod will allow us to keep the latest radio's released modded for all frequencies.
Instead of cross flashing all the time.

Honestly I don't think this is something worth investigating until S-OFF is achieved. Then we have to figure out whether or not the lock on AWS WCDMA can be removed with software means.
The iPhone 5 had the same exact problem. For T-Mobile they released a phone with the same model number as the ATT version but with AWS WCDMA unlocked. Apple was unable to do anything for the ATT users because the lock went so low level that no software could change it, so they had to just change the software from the factory instead.
The same thing may be happening here.
Has anyone figured this out yet using the QPST method in the Qualcomm software like we do with Samsung?

Is there any update on this?
I can understand them locking the AT&T version down at hardware, but no the International version.
Anyone know if I can flash the International to open up 1700 AWS?
Does anyone know if the AT&T HTC One has the 2600 Mhz 4G/LTE band?
The International model does, but not sure if after converting the AT&T one changing the MID, CID and RUU will unlock the band.

?SIM Unlocked Sprint S6 on T-Moile?

OK Question:
I have been trying to find reliable information on this specific question for quite some time.. I am wondering two things:
How well will a Sprint Samsung S6 work unlocked on T-Mobile? I was comparing Basebands or bands or whatever and it has most of the LTE bands but none of the 3G bands. Does that mean that IF I was in a place where LTE was not available that it wouldn't be able to connect to 3G? How well would this work?
Thanks

If you are in the United States, by law the carrier cannot "lock" a phone to be only activated by their own network. You may have to call them to get it unlocked though. They may request for you to pay off the ETF on it, which is usually the remaining balance of the discounted phone on contract.
So really there is no such thing as a locked phone anymore, at least not for now. The hardware on the Samsung S6 should be the same for all carriers, the only difference should be the SIM card.

T865 on T-Mobile

I was wondering if anybody is using the international T865 on T-Mobile, and if so, how is the LTE signal? I know this model doesn't have all of the T-Mobile LTE bands, but I believe it has a couple of the important ones? I ran an international Tab S2 on T-Mobile, and it worked pretty much just fine in Los Angeles. I was kind of curious how this might work now, if the network has changed since then or whatnot, and then how the merger with Sprint might affect it in the near future. Any info is appreciated!

Yeah I don't think that works. Have you tried putting a smartphone sim in your T-Mobile S6? I'm sure the system will recognize it as a tablet and not a phone. That's why I want to order an 865 international model. But then again I guess I might look into how much it costs just to add some tablet data to my plan.

I have a smartphone sim (no difference than an normal sim) and get mobile data which allows me to use the phone when WiFi is not available (I don't want to use my phone as a hotspot). The T-Mobile LTE tablet cannot make phone calls or text but can use the text and call on other devices option on Samsung phones which allows you to use the Tablet using your phone number.
On other samsung devices the US models use the Snapdragon chip while the international model uses the exynos chip which can easily unlock the bootloader and root the phone or tablet. I understand that the S6 LTE tablet is using only the Snapdragon chip worldwide so rooting may be much more difficult. However the international version should have the OEM unlock available so the bootloader can be unlocked. Normally I only get the international versions and root, but if is getting more difficult each year to root the Samsung devices. I bought a used S6 LTE and am happy with my tablet.

So you have a smartphone sim in your T-Mobile Tab S6 LTE, and can get unlimited data? Is it a T-Mobile SIM or another carrier? I tried that some years ago with a different tablet and it didn't work because the system recognized it as a tablet and not a smartphone. That would be cool if it works though, I don't care that much about calling and texting, but unlimited data would be cool.
I like the international models too because they can be used like huge phones lol, but they don't have all of the T-Mobile LTE bands, but I think they have enough that it works okay.

Question Does it matter which model i get? XQ-CT62 US version or Global version?

Hey guys when i go to Sony website and look up bootloader unlock instructions. it says the US variant is locked by verizon.
this is the version i have. Does that mean i cannot unlock bootloader? do i need to return my phone and the global version? The guides posted on here don't seem to mention the model number as if it matters.

Unless anything has changed, it is generally known that Verizon phones have a locked bootloader for customer security and in Verizon's interest.

Yea I am a first time sony buyer. the phone i have is actually the 5 IV which we don't have a forum for yet.
I usually am buying older phones with established guides and hacks to unlock on here. So i simply missed this since i didn't see it plastered everywhere on the front page of the some other sony forums. my bad.
I am not surprised. just ordered the wrong one thinking it didn't matter for the sony brand.
returning mine now. and ordering the 72.

It's the same reason I returned US version and bought international version ct72 . So make sure about bands supports for 71 it has 66 which is TMobile and band 41 which i get some good speed depending on the location I'm in.
same here I wanted to root and Use Repainter app and change fonts and I did have the CT62, but I return it back to Sony and bought the CT72, sad that sony doesn`t allow the bootloader to be unlocked on the CT62.

my exact thoughts, 1600.00, no thanks, buy the CT72 and save some money, only thing is you don`t get the USA warranty when you buy the Non-US version, and some missing 5G band`s and the missing MMWave bands
As @2015Ducatimulti mentioned, there is something missing there between the two version.
There is Hardware differences between CT72 and CT62. The US version supports has mmW support and also more bands that are available in the US such as band 2, 66, and 71 used by TMO in addition to mmW 260 and 261.
if your carrier does not have use of these bands and mmW frequencies, then the CT72 should still work as long as you flash the US version ROM. otherwise, you will have coverage issues due and high call drops due to the limited US band support

Flashing US ROM on ct72 will give you signal issues. So far i haven't found a way to get signal working on it.
That might make sense since the RF hardware is different between them and hence the software might not work as expected
FWIW, I just got the Xperia 1 IV, CT-72, using it on AT&T (primary subscriber, no MVNO). Just using the stock ROM, didn't flash any other ROMS.
So far I appear to have 5G as well as VoLTE. No VoWIFI, but I don't care about that anyway.
I'll use it for another week or so to see if AT&T decides to shutdown service for a non whitelisted device, but so far so good. And it was $840 new, vs $1600 for the USA version, so a HUGE cost difference
I by the way did first have to do the trick where you disable dual-sim and only use the primary SIM slot.
