[SOLVED] T989 works on ATT 3G

Tmobile website listed 850mzh umts, anyone tried with att sim yet? or we need to unlock the phone first?

yes this phone works on all carriers

do we have to unlock first? or phone comes unlocked?

excellent question
i'd like to know that too, as i'm waiting for it as well

he was referring to weather or not it supports at&t HSPA+

and that was the answer...

TMONews.com alludes to this question as well...
I guess Allgamer confirmed the million dollar question for all of us
I guess this will be my future-proof phone (at&t merger or not) for the next year or so.

this is definitely the best phone for a while, until another beast comes along on a quad band hspda+
this phone is literally a 4x4
you can switch to any GSM cell phone provider that you want with the same phone without thinking twice.

i just bought the phone full price.
on the phone box it listed.
gsm 850, 900, 1800, 1900.
umts band 1 (2100), band II (1900), band iv (1700), band V (850)!
so this phone does supports 850/1900 3g too!

Well this is good news at least... I guess this phone is the lube that will make the brutal takeover a bit less painful.

It passed the FCC with AT&T 3G support, there is NO question that it has AT&T 3G support.

So did another recent (in the past 6 months) T-Mobile phone, the G2x. The specs said it etc. I wasn't until after the phone was released and some people actually tried it that they found out it didn't work.
Same caution should go with this device, until someone puts a bloody AT&T sim in it and gets a testable connection treat the specs, web and box with a grain of salt.

Sorry again part of the confusions surrounding the G2X was a possible misstating by several blogs. http://pocketnow.com/android/lg-p999-passes-fcc-is-t-mobiles-g2x for example.
In the end though even if the FCC tests the phone to support those frequencies, the manuf lists the support and t-mob lists the support, until its tested by multiple users I wouldn't believe it. Sorry but I have been burned by to many manuf lies (I own a captivate need I say more) and too much incorrect information.

That model number is for a different LG G2X that T-Mobile didn't sell.
The T-Mobile Galaxy S II is IDENTICAL to the Telus Galaxy S II X - it has 850/1700/1900 WCDMA bands. You can stop the skepticism.

Ahhh so if they are identical then I presume someone tested it on that one?
Specs schmecks like I said until tested its rumored to be supported. I'd love to see confirmations from a reputable source that they have taken an AT&T sim and popped it in. Until that happens people should be cautious is all I am saying. Don't buy a phone and get locked into a contract for a spec thats unproven. Just because the hardware support is there doesn't mean the software can even use it.
I'm not skeptical of that which is proven but I am cynical of that which is quoted without proof. It' not you, or anyone else in this thread but after a years of dealing with telco and manufacturer broken promises, half truth's and specs that are just this side of outright lies...

did LG G2x listed umts 850/1900 on phone box?
this tmobile galaxy s2 does listed umts 850/1900 on phone box!
that is like saying on a honda sticker it listed 500 hp and the car only has 200hp, that' fault advertising, you can sue them!

That is true, they speculated that the G2x COULD have AT&T 3G but didn't "unlock" the feature. There is only one true way to figure this all out, that is to unlock the phone and try an AT&T 3G sim in it

My captivate listed on the box it had a gps, oh its got one allright but it aint worth a crap.
Just because the box says it has it doesn't mean it functions well. It just means its present. It may drop a AT&T 3g call every second due to a software bug that may never get fixed.
Then again it may have a better tuned antenna than the AT&T SGS II and get better reception. We just dont know. We know what the marketing material says but they doe come out and say oops sometimes.

ok guys... this conversation is getting a bit derailed.
The original question and answer is for the SGH-T989 nothing to do with the LG G2x
so stop comparing Orange vs Lemons, or at least make a new topic for your comparison, instead of hijacking this topic

[Q] T-Mobile Galaxy S4 best S4 in the US?

After considering a number of things I've been led on deciding I'd probably want to get an S4 over the other currently available smartphones. I've held off because I had wanted a more premium feeling phone other than plastic, but I realize now I can easily buy an aluminum backing+bumper replacement to give it that look and feel.
Anyways now to the question part of it... I was preferring an unlocked device, but the Internationally sold i9505 and i9500 do not have faster than 3G in the US, or so I've read.
I'm not looking to get a specific phone service right away, for now I want a solid device I'll be happy with for some years to come. Mainly as a portable device with storage and apps, and a little down the road to use it as my mobile phone.
I need some confirmation, but from what I understand the T-Mobile version would probably be the best? Due to once unlocked you can use it on both T-Mobile, or AT&T with 4G/LTE speeds. Also I am led to believe the AT&T S4 does not have the right frequencies for T-Mobile 4G/LTE.
Aside the above wireless speed question, I'd like to know:
1. What would be the point in flashing the i9505/i9500 ROM on the T-Mobile version? To remove T-Mobile association more from the phone... boot screen/software?
2. Does T-Mobile actually sell their version of the S4 at full price, not linked to any plan? Will they provide an unlock code same day, assuming I don't use the free method posted publically. I'm dreading the possibility of having to jump through hoops.
Below I have summerized what I understand about a few non-carrier specific phones....
i9505: International LTE "not working in USA", quad core CPU.
i9500: International 8 core CPU, better GPU.
S4 Google Edition: 4G/LTE capabile, Quad Core CPU, No touchwiz, comes in white color only.
Anyways looking for S4 owner's knowledge, experience and opinions here!

if youre going to pay full price you might want to consider the LTE-A version aka snapdragon 800 version
http://www.ebay.com/itm/Samsung-Gal...1271471972?pt=Cell_Phones&hash=item3384ceb764
32gb+snapdragon 800

According to that auction, it says it wont have 4G/LTE in the US? "I'm a frequency noob" One of my concerns was having something I could use on either TMobile or AT&T so I have options... if I was just looking at a 3g phone and cpu power I could just do this, or the i9500 "8 cores".

it gets hspa+ on tmobile and att it might be able to use LTE-A when tmobile and att add it to their networks
and the 8core isnt really 8 core its 4+4 = 4 low power 4 high power cores, only 1 pair of cores work at a time so its only quad core

Several threads say the 9505 can work on TMobile if you flash a compatible kernel but the 9500 is not compatible. With regard to AT&T vs. TMO compatibility, search for AWS mod. A T-Mobile salesman told me he got his girlfriend's AT&T phone to work on TMO network using that patch.

@OP
My experience is that yes, I could buy the S4 from TMO without plan, just pre-paid with a small credit. I do not live in the US,and had no problem with documentation or payment. Of course it is full price.
What the sales person told me is they will give you an unlock code only after 3 months if you are using it, reloading credit I guess. This doesn't work at all for me, but unlocking is actually real easy with the Samsun embedded app. I bought the phone and tried, it worked immediately (if it doesn't you can hand it back and have it refunded, for the restocking fee of 50USD).
Recently I used the ROM code here from Jamal (http://forum.xda-developers.com/showthread.php?t=2348272), to turn the M919 TMO into a i9505 Nexus. For me it is a massive improvement as I just cannot stand bloatware. It also free up much memory, and battery lasts longer.

The 9505 and 9500 will not get you LTE nor H+ on T-Mobile.
They will ONLY *possibly* get you 4G on AT&T.
The AT&T S4 is locked, yes. Your best bet is the T-Mobile S4.
You can flash 9505 ROMs on the T-Mobile version as well as some other ones.

Additionally, the development for the T-Mobile s4 is outstanding.

Hi,
I m also freq noob and as much as I have searched the forum I cannot find the answer...I have SGH-M919 TMO and I am using it in Serbia but have network problems: receiving missed call TXT msg from operator, dropping out of network and difficulty in reconnecting to home network (need restarting).
Since TMO version supports all bands what can be the problem that phone is acting like that?
It works fine when i m on the network...we dont have LTE here nor will we for some time...
Please some help/direction to the thread dealing with this kind of problem...
Thanks

I had a stock unlocked att s4 on T-Mobile getting LTE without any mods.

As far as my understanding goes, all S models are Exynos for now.
Pro line is Snapdragon.

I think only certain US Carriers use the Snapdragon chip Tab S LTE.

this chipset exynos 5420 is 3g in general no 4g lte .this is new 5420 with lte included or lte has dedicated chipset ?
becuase my note 3 n900 exynos 5420 support only 3g freq. but 5420 in this tablet support 4g let
if use another chipset just for lte power consumption is too much more than 3g

as i know, the tab S model use intel chip to support 4g

I have not (yet) read on any Samsung site of any Tab S using Snapdragon. To avoid any future confusion, I suggest to forget the other sites, and go straight to the source themselves (Samsung) .....

The mods know about the Snapdragon issue. Because Snapdragon is offered in some limited markets they say it should remain. I don't agree as the vast majority of these devices are Exynos. It is misleading but they won't change it.

I could only suggest that they need to " amend " the description, not " omit ". Just add Exynos to it, that's all. Or go the " hard " way and have separate forums same as other devices .... End of confusion

Samsung.com doesn't list any Qualcomm specs for the T700/T705/T800, says they're all Exynos™ 5 Octa (1.9Ghz Quadcore + 1.3 Ghz Quadcore).
The only possible Tab S with a Snapdragon is the T805.

It shipped out today, so I most likely won't know until Monday or Tuesday. But I'd imagine the performance will be just like my Note 3 since it's the same SoC and memory.

Yes, please keep us informed.
I picked up the WIFI version a few days ago after seeing it posted here that BB was discounting the 32GB. I am not noticing any significant lags other than within certain apps that I have also noticed it my Note 8. I would be torn over which to choose, the Snapdragon/Sprint or the 32GB version.
Incidentally, if you chose the the monthly option @ $27 (total $650) , did it also include the cellular plan for 2 years or was that additional? (Update:Never mind, found the answer on the Sprint website)

My Tab S from sprint will be here shortly. I will post back about its performance. I am trying to find out if there is a root method that works for this model.

So far, even with the crap-bloatware Samsung/Sprint like to pile on, and the memory-monster-TouchWiz; this tablet is performing quite well. The Snapdragon definitely makes up for all of the aforementioned annoyances. Certainly more responsive and 'snappy' than the Exynos variant that I've messed around with. I can't wait to see how fast this is going to be running once we have root and custom kernels.
I do find it odd that they went back to the old USB 2.0 port vs the duel 3.0 port though; I get great charge times with my Note 3 using that.

[Q] Tab S 8.4 as a phone. Which version?

I'm in the US and most of the US tablets have the cellphone functions disabled. I'm on AT&T Currently with a Huawei Mediapad X1 (LTE doesn't work, but HSPA+ seems decent enough)
It seems that if I get an international version the phone stuff is enabled, but then LTE probably won't work in the US?
Just looking for some direction as I'm only planning on buying the Tab S 8.4 if I can use it as my phone as well, I have no need to carry 2 devices.
I'm also finding it hard to tell which versions have the Snapdragon CPU. From what I can tell the CPU performance between Exynos and Snapdragon seems about the same, but the GPU performance of the Snapdragon seems much better. I do play a fair amount of games.
Thanks!

I am not great on the version numbers but T705 is the standard exynos 4G version.
I would say go for one where you can get a firmware for the UK or somewhere else.
My T805 (10.5" exynos 4G) has all the phone functions.

Is your T805 a US model?
So if I pickup a US LTE version can I just root it and add back the dialer app to make it work as a phone? Or do they lock out the phone functions some other way in the US?

Mine is a UK T805, but if it is actually that model, so a T705. It will be Exynos 4G. You got a few websites you are looking on that I can look at the models for you?

If I get an international one from Amazon
http://www.amazon.com/gp/product/B00LVUUM6A/ref=gno_cart_title_0?ie=UTF8&psc=1&smid=A1QPS08K9FKKNF
That should work fine as a phone and the LTE ones should be snapdragon 800 equipped.
The issue is these international ones won't work with LTE bands in the US
So that's why i'm wondering if I get a US one (LTE bands will work in the US of course) can I somehow get the software on it to be able to use as a phone (As the US disables phone capability somehow)
My current phone is a Chinese LTE phone, the LTE does not work in the US, but I do get HSPA+ which is decent enough, It would just be nice to have US LTE and Phone working...

I'm on AT&T, I already know the international LTE phones won't work on the AT&T LTE Bands. I'll just have to live with HSPA+

So you would be getting a T707A if you got the AT&T specific one. or a T705 for the international.
There are no T707A custom ROMs, only for rooting. I guess it will not have phone software Regardless of the version of software on samfirmware.
T705 will do 3G nicely, where I live I get HSPA+ and its quick - only get 4G in town.

Pretty much what I figured, I will just get the T705 international one and just live with HSPA+
From what I can tell all the T705 are snapdragon 800's, That Amazon link doesn't say what CPU it has. I'm pretty sure i'd rather have the snapdragon over the Exynos as the GPU appears to be way faster.

I think you will find the T705 is an exynos. Dont be fooled as with the intel modem they put exynos in their 4G versions.

Upgrade to Nougat 7.0 on SM-T807R4 (no cellular desired)

Hi XDA Friends,
First post in a very long time.
Just ordered a used SM-T807R4 from ebay, this is the US Cellular branded Galaxy Tab S 10.5. Got a killer price and did not want pass up.
I have absolutely no intention to ever use cellular data and will never use the cellular radio on in this tablet. Wi-fi is all I need and want.
Anyhow as this is a US device that has cellular capabilities and thus I am 99.9% sure this has the Qualcomm Snapdragon CPU. Can't confirm this right now with CPU-Z but will do that one I get this thing.
I wanted to ask if anyone has thoughts on if this may work with the Nougat 7.0 ROM posted by Schischu based on the fact I don't need cellular.
I had intended to root per:
http://forum.xda-developers.com/galaxy-tab-s/help/root-method-t807r4-10-5-t3326827
Then I'd use the T-805 ROM build (aosp-7.0.0-latest-chagalllte.zip)
Again I don't need or care about cellular (just want wifi), and yes my device almost surely has Snapdragon CPU (and not Samsung Exynos).
It is not clear to me if the Nougat or MM ROMs from Schischu are only designed for Exynos based tablets or not.

Yeah I have the same model and it has a snapdragon processor. I am 99.9% sure nougat work because I asked Schischu he said it won't work on snapdragon processer tablet which is really depressing so I haven't installed 7.0. I am waiting for offical marshmallow to come to the tablet but us cellular is really slow. Also did you get the tablet for 169.99 usd.I got mine but had to 40 in fees since I'm in Canada.

So basically it's clear that the only way to get ROM updates for Snapdragon based tablets is via the US carriers? That is quite disappointing. All recent Samsung Tab S ROMs (MM/Nougat) on XDA are only for Exynos chipsets?
Yea I got the Tab s for that price, and about $10 shipping to CA where I live.
Based on what I read about US Cellular they are in last place with updates, I would not hold my breath for even Marshmallow. I should have paid a bit extra and gotten a Samsung Exynos based unit. Oh well...
Since all the other US carriers (T-Mobile/ATT/Verizon) have released MM (and they too carry Snapdragon units) I would imagine that someone will port this over for US Cellular, but appears to me that XDA is heavily focused on global community where Exynos is the sole chipset.
Has anyone here successfully loaded MM on a US Cellular SM-T807R4 (Snapdragon based) unit????

Thanks steamrollerpark, so then we are making some progress here.
Let's move on to next requirement:
Both of Schischu's MM and Nougat ROMs state that TWRP of 2.8.6.2 or higher is required.
Are the TWRP's also specific to Exynos/Snapdragon?
I can see that Ashyx made v2.8.5.0 specifically for Snapdragon:
http://forum.xda-developers.com/gal...rp-twrp-2-8-5-0-recovery-snapdragon-t3055758/
So build number of this TWRP is too low for Schischu's ROMs.
I was hoping to use: TWRP-3.0.2-1-T805/T807 listed on this page:
http://forum.xda-developers.com/gal...p-2-8-6-1-unofficial-sm-t800-805-807-t3074633
My device in a T807, but it's specifically a T807R4 that is Snapdragon. I know a few T807x devices that are Exynos I don't know if I can use any T807x based TWRP on my T807R4.
Even the website TWRP.me has: https://twrp.me/devices/samsunggalaxytabs105lte.html
"TWRP for Samsung Galaxy Tab S 10.5 LTE"
But I can't tell if that can be used for Snapdragon based devices.

Update: Gave up on this.
Returned the SM-T807R4 and got a SM-T800 (Wifi-only). Looking forward to Nougat!
