Would anyone be able to confirm that Band 12 is for Voice over LTE only as stated in this article?

http://www.androidpolice.com/2015/0...2-lte-support-from-some-unlocked-smartphones/

Would non-voice lte work on band 12 for faster speeds? If so, please post screen shots of speeds with band 12 phone and a separate band 4 phone.

Anyone else experiencing reception issues with s6a vs their old device with t-Mo? In the Los Angeles area, my s6a is searching for network in areas that I had service with my 6 Plus and Z3. Maybe it is actually missing Band 12?

Taking out all the third party websites, I don't know who to believe, FCC, Samsung or ATT.

Is there any way that someone who has the phone can chime in if they are actually getting band 12?
[Galaxy S6 Active] fortemusic:
All I receive is Band 4, I don't believe Band 12 is there or it's disabled.
[Galaxy S6 Active] Sam K:
I believe it does. Please check my posts at the following links from this thead which show the FCC documents for the Galaxy S6 Active that indicate it has band 12.

Owners of S6 active, do you spot any screen discoloration, i.e. pinkish or greenish tint in some parts of screen? Those are best seen on white background with low brightness (best in dark room)... This is common issue because of which I had to return 3 ordinary S6 so I'd like to find out if there is such problem with SuperAmoled on Active one.

Thanks

I have not noticed this on my Active S6

I can confirm that I have forced and get signal on tmobile band 12.
[Galaxy S6 Active] mdneilson:
It is likely that the phone has Band 12, but TMobile doesn't allow it to connect using that frequency due to not being certified by TMO.
[Galaxy S6 Active] dogman99:
I want to confirm that I have tested tmobile LTE band 12 works for DATA.

tmobile VoLTE for band 12 does NOT work, and voice calls do not connect using band 12 (tested).

Just wanted to update so people have a primary source for making decisions on whether they want a S6 Active or not.
[Galaxy S6 Active] mdneilson:
TMobile is ending all connectivity with ALL non-VoLTE phones on band 12. This is due to FCC regulations regarding EMS capability. I'm frankly shocked that yours still connects, as most unlocked phones with B12 have already been refused by towers. Maybe it will still connect when a fallback GSM/HSPA connection is available.
[Galaxy S6 Active] ubcs2010:
curious about the functionality.

Could you let me know if the phone has any issues? And are you still able to view visual voicemail or do you have to download the app for it?

I just bought a s6 active from eBay with unlock code from ATT so i gotta anxiously wait for it to arrive in the mail next week. I had a sony Z3 for Tmobile but it cracked and i need a more durable phone which is why i was doing a bunch of research for the active on Tmobile network.
[Galaxy S6 Active] mikysee:
I can confirm that the S6 Active can connect to T-Mobile's LTE band 12.

[Galaxy S6 Active] mdneilson:
Well, this certainly has me tempted. If only the VoLTE worked.

...and hopefully TMO doesn't cut the band 12 access off.
[Galaxy S6 Active] Dranakin:
I won't meet the 60 day requirement for my S6 Active to qualify for the AT&T unlock. Can anyone recommend a 3rd party unlock site? How much does it usually cost?

This might lead to more band 12 support from AT&T phones.

[Galaxy S6 Active] Heinous:
Still working? What about WiFi Calling? I'm looking for something to replace my Xperia Z3...
[Galaxy S6 Active] mdneilson:
WiFi calling will work only on some Marshmallow devices and TMobile devices, because it requires a special modem firmware that supports it (so, the S6 Active will never have WiFi calling unless AT&T enables it - unlikely). I also wouldn't count on B12 working forever. TMobile was hit with a huge fine for not having 911 service accessible when on LTE only, so they're disabling B12 access to phones without VoLTE support (which to my understanding, this S6 doesn't have).
[Galaxy S6 Active] Heinous:
I was under the impression that WiFI Calling was built into Android 6 and was working for some people on 5.1.1, and that as long as you have a T Mobile SIM it will work. I guess if AT&T specifically excludes it, and flashing an unbranded ROM is not possible, then this is not the phone for me. Thanks.
[Galaxy S6 Active] dsmero:
Anyone have issues using the Wifi Hotspot? I am on Crickett, and get an error that my account isn't provisioned and to call 611. Everything works with the phone. I bought the phone used from Swappa and wonder if I need to unlock it.
[Galaxy S6 Active] mikysee:
Why would ATT have to disable B12 on an ATT exclusive phone?
[Galaxy S6 Active] mdneilson:
TMobile has control over their towers. There are phones with B12 that can't connect to TMO towers on that band, because they reject the connection at the AP... or at least that is my understanding of it. I could be totally off base.
[Galaxy S6 Active] Kjyo:
Does anyone want to recommended any unlocking companies? I bought as an inactivated device at Best Buy in full and they said they can't do it. Should I be able to go to am att store and get it for free?
[Galaxy S6 Active] MizuRyuu:
If you got the phone from Best Buy and you paid in full, you should be able to request an unlock from AT&T directly here: https://www.att.com/deviceunlock/#/

It shouldn't take more than 3 business days or so for them to send you the unlock code. I got mines in one business day
[Galaxy S6 Active] MizuRyuu:
As a quick update:

For people who are unlocked on another network, seem like you can update through Smart Switch. I am seeing the new update despite not seeing any of the previous patches before. And since the new update is for 5.1.1, I assume it would include all the previous patches.
[Galaxy S6 Active] mikysee:
I tried using Smart Switch but it doesn't show any updates are available.
[Galaxy S6 Active] B_A_BARACUS:
Me too

Bought s6 on ebay. Att would not unlock because buyer was on the next program not paid off yet. The cellunlock.net didnt care and for 24.99 sent me all the codes plus the unfreeze code in two days. Went on tmobile no data. followed the apn settings change, and on t mobile everything is fine now. Never had a problem with ATT till I left for Tmobile,then they became total pricks. Thank you so much for the apn settings info. You guys save the day again.
[Galaxy S6 Active] MizuRyuu:
The problem doesn't sound like AT&T. The phone was on the NEXT program, so it wasn't eligible for carrier unlock.
[Galaxy S6 Active] rihc55:
So i saw two people say the confirmed that band 12 worked on the S6 active based on experience vs what they read online.

[Galaxy S6 Active] crapixm:
could someone expand on how updates would work if used on T-Mobile ?
[Galaxy S6 Active] ap27:
^You would have to manually update. I think there's a thread on here about it. Have to use Samsung's SmartSwitch (or something) software.
[Galaxy S6 Active] IvanAndreevich:
Bought a Galaxy S6 Active from AT&T and had it unlocked with the intention of using it on WIND in Canada which uses AWS 1700 mhz band..

Sadly, it doesn't show the Wind home network in the list of operators at all. I can't select it manually, and it selects Wind Away automatically.

I can see here for the Active

3G bands	HSDPA 850 / 1900 / 2100

..vs the regular S6

3G bands	HSDPA 850 / 900 / 1700 / 1900 / 2100 (G920T, G920A)

This is probably the problem then. Why they would they remove that is beyond me.

Is there anything I can do, such as flashing the modem firmware from the S6 to the S6 Active? I've never done this, but I'm technically inclined.
[Galaxy S6 Active] IvanAndreevich:
The answer is basically forget it. Don't buy a Galaxy S6 Active if you want to use it on 1700 Mhz HSPA+ AWS band.
[Galaxy S6 Active] swamp dog:
I want an Active on T-Mobile but my main concern is does the mobile hotspot work on T-Mobile? If if does, I'm getting one. If not I'll have to settle with a regular S6.

I too have a Galaxy S6 Active. It's not my every day phone. I used unlockriver.com to get my unlock code and when I switched the sim to an activated sim from T-Mobile, I didn't need to configure the APN and it connected to LTE all by itself.
[Galaxy S6 Active] swamp dog:
You had no problem with mobile hotspot either? The reason why that is my concern is that if I want to use my computer's internet I always use my phone's (Moto X 2013) router.
[Galaxy S6 Active] RicardoSal24:
I wouldn't know how to tell you. Like I said, it's not my Every-Day-Phone but I believe there shouldn't be a problem with mobile hotspot.
[Galaxy S6 Active] reagan.a:
Bought an s6 active this past weekend and put in the recommended apn settings from a previous post. But I'm still noticing a huge drop in data speed/coverage, especially inside buildings and certain parts during my highway commute. Since the lack of support of band 12 is a hardware issue, there isn't much that can be done from our end, right?
[Galaxy S6 Active] gregk232:
Correct

I found it to be no issue at all in the Dallas TX area, but it depends on where you live
[Galaxy S6 Active] reagan.a:
Very true, band 12 seems to be pretty heavy in my area. Kinda sucks, because I don't think there's a better phone out there right now in the sub $300 category. Great camera, battery, and cpu for a 5.1 inch phone. Being water proof is just icing on top.
[Galaxy S6 Active] reagan.a:

[MENTION=7966633]bigred177[/MENTION] i noticed a few things thats not the same with mine, here are my screenshots as well as a speedtest with my settings.
[Galaxy S6 Active] mmveets:
Preferred network settings?

So I had a S6 Active working nicely on T-Mobile in the US, and then the screen got cracked. I picked up another one (used), but the mobile data is not working the same. I get poor or zero data in places where it used to work just fine. I checked all the APN settings, and those are fine. I'm starting to wonder if it's a problem with the "preferred network settings" in the service menu. Does anyone know what the appropriate settings should be, for example WDCMA preferred, versus LTE only, versus LTE/GSM auto, etc.? There are a lot of choices, so I'm not listing them all here.

While we're on the subject, if anyone can confirm proper settings for the other options in the service menu, that would be great. For example, should "LTE RAM DUMP" be on or off? and "SMS OVER IMS"? and "IMS REGISTRATION REQUIRED"? and whatever "CELLINFOLISTRATE" is?

Thanks!
[Galaxy S6 Active] mmveets:
Could those who have data working fine on T-Mobile, and those who don't, post what specific android version they're on?

My replacement phone is on v9 - 6.0.1 - G890AUCU4CPH3 and I'm having issues.

My earlier phone was on v8 - 6.0.1 - G890AUCS4CPF3 or v7 - 6.0.1 - G890AUCU4CPF1 (I guess I should have written it down), and data worked fine.

I wonder if AT&T changed something in the modem file and screwed things up.

On a similar note, does anyone know whether it's possible to downgrade from v9 to v7? I've seen the thread about upgrading versions, and noticed that it's not possible to go from one major release back to an earlier one (like nougat to marshmallow, or marshmallow to lollipop), but I can't find any info on whether one can go to an earlier version within the marshmallow range.

Thanks for any help or insight you can provide.
[Galaxy S6 Active] shazish:
I'm having the exact same issue. My older S6 active works just fine, but the new one with the exact same APN settings has very spotty reception and barely any data.
[Galaxy S6 Active] ohms139:
Has anyone had any issues with their unlocked S6 active no longer working on T-Mobile? My S6 active stopped working the other day, I called up Customer Service and they said they are having issues with non T-Mobile branded Samsung devices not working correctly and I would need to goto the Samsung Kiosk at Bestbuy to have them update it.

I did a non root flashe to Android 7.0 build number NRD90M.G890AUCU6DQD1 and made sure that all the APN information was set and neither resolved the issue.

Any ideas??

[Galaxy S6 Active] ohms139:
[MENTION=4365431]Ajfink[/MENTION] yup NYC
[Galaxy S6 Active] Ajfink:
Bad news, then. T-Mobile is shutting down a lot of its 3G spectrum to move it to LTE, and since the S6 Active doesn't support T-Mobile's VoLTE, the ability to make calls is going to be impacted. Basically...you're going to need a new phone.

Different phone, same thing: https://www.reddit.com/r/tmobile/comments/6npakq/no_more_3g_on_older_phones/

[Upgrading, Modifying and Unlocking] ChristoA1:
So, I'm going through the process of cleaning out and fooling around with a second-hand Wizard I got cheap. I go through the hard reset, all the functions seem to work out alright, etc. So now it's time for me to unlock it! :) I go through the process of SIM unlocking it with a coworker's SIM card. Easy as pie. Ok that's done, now to CID unlock it. This one's another G4, so unfortunately I have to fork over money to unlock it.

So I go to IMEI-CHECK.CO.UK, and pay up the 20 GBP (Which comes out to $38 USD), and get the software and the .unl file. I've done a backup, everything, etc. I go to run the program, and Windows SHUTS DOWN. Kind of annoying. But you know what? It happens, and I email them. I get a very nice reply after like 5 minutes! Impressive, considering they're off in the Chinese Never Never Land. We go through a couple emails, again quickly, and I start getting the impression that they don't know what's going on either. That's OK, I'm a software developer, I understand :)

So we go through some troubleshooting tips, and then mention that support for Vista is Beta. Now, on the page, it says "Note that the unlocker work only under Windows 2000/XP/VISTA. It WILL NOT run under 98, or ME." Nothing about Beta, so I mention that they should probably put up a notice or something, and that I'm still willing to help troubleshoot if they are. Well, eventually they get to a point where they say that I need to use another computer, or do a full re-install of Vista. Unfortunately, I only have one laptop that I use for both home and work, so re-installing is not an option, and I can't run unauthorized software on office-owned computers.

So I politely mention I'd like a refund, and if they ever get the software working, I will rebuy it! At this point, it's taking about a day or so to get a response from them, so I file a PayPal claim. Unfortunately, I get an instant response from PayPal:

"As stated in our User Agreement, the claims process only applies to the shipment of goods. It does not apply to complaints about the attributes or quality of goods received. Therefore, we are unable to reverse this transaction or issue a refund."

So, I'm out $40, and PayPal could care less, and the folks at IMEI-CHECK could care less, because they're pretty much running a monopoly on this software.

Don't buy from them if you have Vista. I wouldn't buy from them at ALL personally, I'd wait until *eventually* a free G4 solution comes out. There are other methods of flashing ROMs.

And PayPal SuXorZ. Yeah, I had to go there. :mad:
[Upgrading, Modifying and Unlocking] TaurusBullba R.I.P.:
Wow, that's a bummer. I haven't had to deal with these guys myself, but I know PayPal's "protections" are pretty bogus.

My question is why did you waste your time with those guys anyhow? You can flash any carrier/cooked ROM you want without paying anyone. Look here.

So, save your money and flash away! :)
[Upgrading, Modifying and Unlocking] ChristoA1:
Yeah...

I just figured if I could get it CID unlocked, I wouldn't have to go through the ShellTool hassle (I've actually had good luck using RUU through Vista on another Wizard). That would have been worth it, IMHO. But I got burned, and just wanted to warn others to learn from my mistakes. (IMHO, it wasn't a mistake, but then again, I was the impatient one, lol)

Lesson learned. $40 lesson. But learned.
[Upgrading, Modifying and Unlocking] AlanJC:
I'm sure they will resolve this issue for you, or refund you. IMEI check have always been fairly good from what I have seen here. I have used them twice myself, and florin who I think is one of the main people behind it, has done lots for the community over the years.

Just be patient, sounds like it's paypal that's screwed you, not IMEI check, not yet anyway.
[Upgrading, Modifying and Unlocking] Madcap180:
One thing you CAN do is copy the files to your storage card.. and use a friends computer without Vista to unlock.
[Upgrading, Modifying and Unlocking] hdubli:
If computer shuts down then check yr active sync version..it shd be anything but not 4.5...try and yr computer will not reboot..:)
[Upgrading, Modifying and Unlocking] ChristoA1:
Thanks for the replies

Looking throughout the forums, I've noticed that Florin's bumped up against some people, but you're correct, he does seem to eventually work things out. Given it's the weekend, I hold hold it against them for now. :)

I'm not worried about losing files on this one, it's a unit that I just got from someone, so I'm hard-resetting it anyhow.

Unfortunately, like I told IMEI-CHECK, I don't have another computer that I can use (other than work computers, but those are off limits).

Having Vista, I don't have ActiveSync; I've got Windows Mobile Device Manager, and it's up to date.

I appreciate everyone's help in this community, and I don't know if I made it clear enough in my first post, but I'm more anti-PayPal than anyone else :-P
[Upgrading, Modifying and Unlocking] ChristoA1:
Update...

I am still in email arguments with IMEI-CHECK. I originally contacted them on the 18th, still not getting any kind of good reply. Does Florin represent them, work for them, etc? I am constantly told to use another computer, when I have, in many emails, explained that I do not have access to any other computers. This computer doubles as my personal and business computer, so re-installing a fresh copy of Vista is not an option at this point, when Vista does not seem to have any issues.

I am really hoping that IMEI-CHECK steps up and does the right thing...

*sigh*

p.s. PayPal sent me a survey on what I thought of their *cough* "customer service". I basically told them where to stick their survey.
[Upgrading, Modifying and Unlocking] NetrunnerAT:
i have use imei 4 times ... they have fix a error for me only for the price of unlocking my g4 prophet!

some guys have trouble with the ipl/spl 3.08 version and imei have fix too.

talk with they guys ... but ... here you found a lot of threads with vista problems! if you have no changes to use XP ... try vmware and emu. it!
[Upgrading, Modifying and Unlocking] ChristoA1:
Finally!

First email: Jun 18

Rec'd Ref.: Jul 4

Ok, so finally IMEI-CHECK proposed a deal that I send my phone out for someone else to do the upgrade. They offered GBP100, but apparently it was a bluff. I *accepted* their offer, and next thing I knew, there was a refund. I lost a dollar in the GBP<->Dollar but I don't care. :p

Funny thing, I actually got a email from Pay-Pal after the whole mess, saying that they completed their investigation and I've been refunded. For the record, no PayPal, you suck, you didn't investigate sh*t. :mad:

Here's my proposal to IMEI-CHECK: I have kept the .UNL file. If you release a version of the program that I can use, and that works, I'll pay you! (I haven't decided if I'll pay full price after everything, but still, I'm an honest guy, and I feel like it's worth paying for your time and effort) :cool:

For the record, if anyone can use the .UNL file, let me know. I know it can't be used to unlock your phone (unless you happen to have the same IMEI as I do o.o;; ), but it could be used for testing/development! :)

I like smiley's.
[Upgrading, Modifying and Unlocking] raskal:
after reading your endless bla bla, i can just suggest you one thing:

1.) use your device with your's provider original sim card, so you don't need unlock it

or

2.) use a normal OS on your pc

Even those guys are my competitors, i have to say that they have pretty good soft and it works.
