Hey everyone,
Just wondering if there any big difference between between the Tmobile and AT&T samsung tab?
Does one have better features or better pre-loaded apps? Are both easily rootable? If so, which is better?
The only internal hardware difference is that the T-Mobile tab supports the T-Mobile 3G bands whereas the ATT tab supports ATT bands. Also, the ATT tab will be better if you were to travel a lot in Europe as it can support European 3G frequencies.
There are also some changes in design on the back of the tab (mostly in regards to color). As for preinstalled apps, I an unsure as I do not own a T-Mobile tab.

The T-Mobile one will work with T-Mobiles faster 3G HSPA+ network. Not at 4G though, just faster than 3G. However, this it not available everywhere.
In the EU, the T-Mobile version will only support Edge, whereas the AT&T version will support 3G.
The most important piece is AT&T version could be used as a phone w Euro firmware and an existing AT&T SIM card. Sounded like you're not an AT&T user but it's doable.
For Tmob tab, you could also set it up as a phone but you will need a data plan then setup GV+IPKall+SIPDroid if you don't want to pay for Skype.

It can?
I know it wont wont in the UK, as their 3G frequency is 2100 and i believe the T-Mobile tab uses a different frequency for uploads vs downloads (1700 and 2100).

It will work in the UK.
Read the specs. Follow the link, and click on specs.
The TMo US Tab supports:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

I got the specs from Samsung's website, they are posted as:
GSM: 850, 900, 1800, 1900; UMTS : Band IV(1700), I(2100) & Wi-Fi
I read the UMTS bands as the AWS 1700/2100, (1700Mhz u/l; 2100Mhz d/l) not AWS(1700/2100) and UMTS 2100 (so only able to download on the 2100, not upload on this frequency).
It does seem a little unclear, but if it really does support 2100Mhz upload and download, that would be awesome!! Would also mean you could unlock it and put a 3G AT&T Sim in it...
Anyone know this for sure?

Trust me, it's fine.
Band IV is AWS and completely separate from Band I. Even the Samsung website explicitly mentions the bands it supports. European 3G uses Band I so it will work.

That is awesome.. The only thing, other than cost, holding me back was that it might not work in the UK.
Now I just have to convince myself that i will get $350 + monthly data use out of it. Price, though expensive, is not really an issue but if I bought it and didn't use it, i would get into trouble from the missus.... :s
Flash T-Mobile Tab to support AT&T Voice
FYI - I followed Rotohammer's directions and i flashed a T-Mobile Tab, then unlocked it, and after I inserted my AT&T sim, I had phone and Edge:
http://forum.xda-developers.com/showthread.php?t=886714
However, I'm trying to figure out if I can load a new modem and get AT&T 3G on this tab (bought from T-Mobile)? I tried the bell modem but it didn't work. Am I safe to assume that the T-Mobile hardware will support AT&T 3G and I only need to find the right software?
Thanks - these forums are great... Sorry if this is the wrong spot.

Don't waste your time and or brick your Tab. Tmo Tab will never get 3G on an ATT sim card because it doesn't do 3G on 850/1900mhz band. Hardware doesn't support ATT's 3G bands.

I understand the feeling. I initially went with the Tmobile version but at a data rate coming up to almost $70 after taxes ($59.99 unlimited data for not having my phone with Tmobile), I took it back, paid the $10 restocking fee and went with the at&t version. After roto's rom to enable phone i just plop in my existing unlimited (grandfathered) at&t sim and i'm golden.
Either way I did the analysis....and i believe it was after like 8 months the AT&T version comes out cheaper and if i recall that was WITH the 2GB data plan included.

Tmo does not have a $59.99 data-only plan. It's $39.99 for 5GB, after which you're throttled past the 5GB allotment. No overages.
But i prefer AT&T's $24.99 2GB plan (don't need calling, already have a phone). The price is just right. Still looking to trade my Tmo Tab for an ATT one...
Yup caught me off guard. The the tmo salesman explained it to me instore. If or when I take my phone with tmo I will get a $10 discount on the data plan. Fishy but whatever, I was never a t-mobile customer so I just went along with it but yes normally its 39.99
Bumping this as I was going to get a WiFi only TAB but with its inferior hardware I'm looking at a 3G TAB.
On Amazon the Tmobile version is a lot cheaper at $475 than the AT&T version at $550, not sure why?
Anyway I'll be using it in Europe so it seems the Tmobile version would do the trick with its 2100Mhz frequency?

The AT&T version has always been more expensive...just the way it's been priced I guess. If your only or mainly going to be using it in Europe you will be fine with the T-Mobile version as it will run 3G on 900/2100 over there
If you're keen on digging around with different roms and are comfortable flashing around then go for it. But if you're looking for a smooth out of the box experience off the bat (with calling etc enable) I'd wait and pick up one over there....just my 2 cents
Will the captivate be one of the devices to be eligible for the software upgrade for LTE/4G as noted here, "...any of your AT&T LTE-upgradable devices will be able to connect to LTE after performing a simple software upgrade."
http://www.wireless.att.com/learn/why/technology/4g-lte.jsp
Hrm.. well it says "selected markets" which translates to NOT COLORADO SPRINGS
But I'd imagine it'd just be a modem upgrade.... but could be hardware dependent no?

From what I understand the LTE network will be somewher ein the 700 MHZ bands and as that is outside what the antenna for the captivate can do, the answer is a sad no.

Agreed. Could always grab a rom that supports H. Pretty much 3.5G. Anyways att is struggling with 3G so I would say 12th of never on a 4G network.
Well as far as I know the physical modem itself would have to be different as it is not just the MHz that it runs at.
I'm on at&t. I have an N1 that I bought full price, off-contract.
I've now purchased a Nexus S and planned on giving my Nexus 1 to my girlfriend who's on T-Mobile. I *thought* the phone was supposed to be unlocked but there's obviously lots of confusion about what "unlocked" means.
I've found that t-mobile N1's wont work on at&t 3g, but I've found nothing concerning the other way around.
Could someone give me a clue if this will work?
The phone will work fine, but only on EDGE speeds. There are two different phones because T-Mobile and AT&T use two different frequencies for their 3G networks.
Please read the FAQ, question 13.
Why would you think it could work one way and not the other? If it cant work on at&t because of hardware the same rules apply the other way around otherwise there one only be one model.
Thanks for the replies.
So is there a way I can get this at&t unit to work fully on t-mobile? It appears not. I feel mislead.

Nexus One is not capable of "4G" speeds anyways, not matter what network / device model you use. It has a theoretical max download of 7.2Mbps and does not utilize a HSPA+ radio which is required to access Tmo / AT&T's "4G" network.

yes true, my bad i meant to say 3g
the att model is limited to 2g only when on tmo network
Ok, I know this is an odd question but I am confident it can be answered here.
I want to buy another android phone, it needs to be something fairly recent that ATT still stocks at least online if not at the stores so I can use an upgrade.
And I want to be able to also use the TMO 3G system/frequencies with it.
I know the unlocked Captivate won't work on the TMO 3G system but does anyone know if any other phones have the proper radios to support both ATT and TMO frequencies when I swap out the sim card?
Just to reply to my own thread, after an hour or so of searching its looking like ATT phones currently available do not have the required 1700hz band that is needed for TMO 3G speeds.
I am hopingIi am wrong here and that someone knows otherwise.
I did find a few references to some TMO phones working on ATT bands but those obviously wont help me if I am trying to use an upgrade discount.
I was only searching current ATT phones so if someone knows of an older version let me know too.
Well I would recommend finding more concrete evidence on what freq Tmo has in your area and try this before buying but for example (acording to phonearena) Tmobile's Galaxy S 2 runs GSM 850, 900, 1800, 1900 same as ATT"s Galaxy S 2 (not skyrocket). TMO's Galaxy S runs UMTS 1700/2100, 2100 mhz. ATT's Galaxy S 2 (not skyrocket) runs umts 850, 1900, 2100 mhz. Meaning its possible to get edge, 3g and HSPA+ on att's Galaxy S 2 (not skyrocket) on Tmo. But That would depend on your area and how Tmo uses the different freq.
Edit: Its just an example but you can check more phones to see if any of them have overlapping frequencies.
So maybe there is hope.
I was under the impression that TMO needed 1700/2100 for 3G in my area as one was an upload and the other a download frequency.
What I did was pull up all the Android ATT phones I was currently eligible for and then typed the name into the xda search bar followed by 'tmobile'. That would usually take me to a thread in which someone was asking if that phone would also work on TMO 3G and it was invariably replied that they would only work on Edge with a TMO sim card.
I didnt check the GS2 or the Skyrocket though. I will do that today. Thanks for the reply. I knew there would be xda members out there that would have a better idea than me of how to find out.
I will do you a favor and check both of my gs2's with my wife's T-Mobile sim tonight.

A bit more research on xda says that there are some TMO phones ( Defy and Amaze 4G ) that work on the ATT 3G bands. That doesn't really help me much though. LOL.

Skyrocket won't work. It doesn't have UMTS 2100 (Skyrocket runs on 850, 1900). The "Attain" (none lte) might because it has 2100.

This thread says we are out off luck on this quest.
What I said. It might depending on the area. If where the OP lives Tmo uses the UMTS 2100mhz then he is lucky else he is SOL.
Edit: after finishing reading IF the phone uses 1700 for dl and 2100 for ul then ya tough luck D=
Hi all,
I was wondering whether there would be any way to flash a custom modem or a ROM that would unlock the LTE bands so that the Vivid can access HSPA on Tmobile's network?
From what Ive read, the AT&T GS2 Skyrocket and the AT&T Galaxy Note have been unlocked through this method and Im not sure why the Vivid cant be since it shares much of the same specs between it and the Skyrocket & G-Note
Thanks

No that isn't possible, tmobile and att have different bands. I know that you could use a sim card on the vivid, but you wouldn't get the same speed.

No. The LTE Band will never work on T-Mobile's GSM. What allows the Note and Skyrocket to work is that they have the pentaband hardware GSM modem and flashing a different software modem enables access to those frequencies on GSM.

Uh yeah, it's going to be hard to get the LTE bands on the LTE radio on the phone to pick up UMTS/HSPA signal.
There's a reason why phones are usually advertised like:
GSM/EDGE 850/900/1800/1900MHz
UMTS/HSPA 850/1900/2100MHz
LTE AWS700MHz
They kiiiinda aren't interoperable. Note how you can't connect to UMTS 900MHz or use a Telstra LTE phone and get 1800MHz 2G service if the phone doesn't have that band in its 2G spectrum.
I remember reading about the pentaband radios having UMTS/HSPA 850/900/1700/1900/2100MHz. That's still pretty different than your standard quad-band GSM radio.
It is absolutely possible...given that the specs on GSM Arena and Phonescoop are right...
700 MHz Class 17, 1700/2100 MHz
It has the correct pair for Tmobile.
The only thing is whether or not you can flash the radio with a Tmobile equivalent (Amaze?) radio.
What happened to all the hardware hackers on this forum? It seems as if no one knows ANYthing about the interworkings of a network anymore.
Anyhow, the phone having the bands and knowing what to do with them are 2 different things. For example. Stereo FM 101.9 Mhz vs. HD(Digital)-FM 101.9...they're both on the same band/frequency but are utilized differently...
The signals are still transmitted on the same frequency, however the radio itself doesn't know how to decode/interpret the HD (Digital) signal...unless it is told how to do so.
The only place that this analogy differs is when it comes to actual comparison of FM receivers and Cellular phones. With FM receivers it actually requires a decoder to understand the digital signal being broadcasted...Cellular however just needs to be flashed and voila, you've got HSPA...
So. Yes. It is %100 possible.
NO NO NO NO.
LTE bands do NOT equal GSM. Not going to happen. They are physically different receivers for lack of a better phrase. There is no way to do this without physically changing hardware. Also, you realize T-Mobile's "1700" frequency does not actually mean 1700 on the dot. They use a different subset of actual radio bands than AT&T's 1700 LTE. As in 1721-1727 or some such vs 1781-1793 or something. I don't know the actual frequencies, but you get the drift.

Hand is hitting my face so hard right now.
RavenII, if it's so possible, then why don't you do it? If you can't, give a large donation to one of our developers and tell them to do it.
I, and many others here are blatantly telling you it's not possible for clear reasons.
The Galaxy Nexus has a PENTABAND UMTS/HSPA "3G" radio. 850/900/1700/1900/2100. That's why it can access TMobile's 3G and faux-G. We here, on the HTC Holiday, have a tri-band 3G radio.
DIRECTLY from your sources at GSM ARENA and PHONESCOOP. I've added HTC.com for good measure:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
GSM 850 / 900 / 1800 / 1900
LTE 700 / 1700
WCDMA 850 / 1900 / 2100
LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)
What? I'm sorry, I couldn't hear you over the fact that "3G network/WCDMA/HSPA+/UMTS" doesn't have 1700MHz. Oh wait, I couldn't hear you over the fact that TMobile's faux-G is not based on LTE, nor is it 4G (big hint: it's 3G HSPA-based service ).
GSM Arena and Phonescoop also do not account for the of LTE bands supported by the Vivid. Each region of the Holiday pretty much only supports the LTE band in that region. Rogers and ATT only supports AWS700, Telstra only supports 1800, etc.
I'm glad I'm not the only one to retain my senses about this. Leave it to a fellow Saab fan to explain it correctly.

Ok...I really didn't want to do this since I HATE spoon feeding people on forums...but here goes. And try to keep up because I'm only going to dumb it down so much.
What you guys are mistaking for "Bands"...really ARE NOT BANDS....there is NO SUCH THING as an LTE band...or HSPA+ band...
There are Network types ...LTE, HSPA+, -Insert other modulation/channeling scheme here-, etc.
There are Frequencies (which are actually specific ranges but for the sake of confusion, they're referred to as the following 700, 800, 850, 900, 1700, 1900, 2100...etc.) By the way...all those frequencies fall under the UHF band...
So far we've established that there are Network types...and different frequencies...are you still with me? Any questions?
Ok, onward.
There exists something called an SDR or Software Defined Rado...it has the ability to receive and transmit on certain frequencies...It's the software that defines how much of that frequency to use per channel (1Mhz, 25khz, etc.), what range of frequencies to use, how to use them, how much power to use while transmitting, among MANY other things (what frequency to send on, which to receive on, etc.)...That's how they came up with "Software defined radio"
If you look at the Product Brief for the MSM8X60/APQ8060 you should notice all of the frequencies that these specific chips support...
I really don't want to lose you guys, still following?
You might notice that the APQ8060 doesn't have a WWAN modem...but what does THAT mean? It means that it needs something like ohhhhh let's say the MDM9200...FINE! Here's one more spoon full
Reader to me: But RavenII...you're being a condescending ****, and we still don't know what the hell your point is...you're spewing all this **** like you're some know it all...
Me to Reader: There there grasshopper. I will get straight to it...
With all of the information I've given you...you should be able to see that when you see something like "LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)"...it means the radio is...
Being told to use LTE Standards (modulation, channeling, frequency steps, etc.) on AWS/700 (which if they're using AWS to signify Band IV...it would in turn mean 1700/2100), HSPA+/UMTS Standards on 850/1900/2100MHz...etc.
Still reading?
When I say that it is %100 possible...I'm saying that with software or "flashing the radio"...you can effectively change/tell what the chip should do (in this case either an MSM or MDM) with the frequencies it's capable of transmitting/receiving on. That's it.
Aus_Azn: I really hope you didn't leave a hand print on your face...
Thank you, good night.
One last thought: I never said that I would do it, I said that it's possible...
Here's the real simple way to explain it: it is theoretically possible to do but no one outside of HTC has the skill or proprietary code to do it.
So for all intents and purposes, impossible. It will not now nor ever happen.
Also, while the chip may support all bands from the factory that initially fabricated the chip, it may be locked at a firmware level (not a software radio, but actual ROM on the physical chip) that a software based radio cannot affect. This is why you can't just flash a T-Mobile software radio on another AT&T s-off device and have it work. The physical chip itself DOES NOT SUPPORT THE FREQUENCY NEEDED due to changed firmware configuration.
Is that condescending enough for you?

Let's see, how can I put this...You're still wrong. It's still possible.
I don't even own a Vivid so I'm no longer going to post to this thread...but I will tell you this...everyone once told me that blackberrys could not have data without having the BIS (Blackberry specific plan)...and guess what. I'M the reason that people are hacking them away. I was the first one to figure it out and prove everyone wrong. While I don't have a phone that I need to convert for T-Mobile, you can bet, that once there's a phone that I want to use on T-Mobile's network...I'll more than likely find a way.
Farewell.
@totally off topic
RavenII I think you're going on the right track here. I'm already convinced by what your saying.
peaceout
What RavenII is saying does have a good base logically because it has been done before for a very similar set of hardware to the raider. The ATT Galaxy S2 Skyrocket and the ATT Note LTE are both phones featuring very similar processor and modem as the Raider. The APQ8060 and MDM9200 (i think).
Samsung released devices with this modem running on all sorts of bands 1700, 850, 1900, 2100 and even LTE on 1700 and 700.
The ATT Versions of the devices do not feature UMTS in AWS range however people have simply flashed the modem from the T-Mobile version of the device which doesn't have LTE and the ATT LTE devices actually started working on UMTS AWS bands. Various modems give various degrees of success but it is possible and has been confirmed many many times over.
Here is the thread for the ATT Skyrocket. You will find people doing the same thing on ATT Galaxy Note LTE.

You guys are funny, now I can't wait to get my Vivid which I just received today running on T-Mobiles "4g". The funny thing about this is when i very first started reading this thread and saw Mr. buknastys' reply, I was thinking "That is absolutely not true". Now I'm not going to go into detail or try and prove any points, as Raven has done a perfectly fine job proving his point and answering the OPs question. Bottom line; the two readers are absolutely wrong and Raven is absolutely right. Also one last thing, I love how suddenly a firmware "lock" is something of an obstacle, yet we have gained S-Off on nearly every HTC bootloader out there. Just sayin..

I really didn't mean to come off as a **** in this thread, but it seems as if though people have forgotten about actual hacking and everything has moved to "Supercharging" and theming...it's saddening, I come from a time where there was no such thing as impossible.
...I encourage you to try, but do so with a lot of caution...because the fact of the matter is...you can brick your device...
Happy hacking.
THANK YOU!!!

I would just like to say thank you to Raven as I now have a AT&T Vivid and have successfully placed it on the T-mobile 3G network working 100% of the time. I will be putting together a full tutorial on how to do this shortly as it was indeed a challenge. I have been reading these forums for awhile and Raven your post has by far been one of the most beneficial and inspiring ones...thanks for sticking it out on these forums...few do these days. I actually just joined this forum after months of reading because of this post. I figure i too will provide feedback. I am actually a Tech Manager w/ Sprint. I work on these things everyday in other words....hints why I actually have a T-mobile phone lol. Not saying T-mobile is the best but you at least get exactly what you pay for and they are honest about coverage haha. Anyways..back on topic...the HTC Vivid is an interesting phone to root even and get the S-off. It is needed in order to get the sim unlocked. You have to do a combo of the rooting kit "Vivid_All_in_One_kit_v2.2" posted on another section and the "ControlBearRelease_holiday_ICS_WIN" (if your running Win 7). After you do what they call the "wire trick" (basically short the sim reader temporarily to allow temp access to flash) you can get the sim lock off. After that it is simple trial and error with modem flashes from various tmobile devices onto the HTC Vivid to get the 3G up and going. Mine actually kicked on with the AT&T radio flashed at first but I only had coverage in certain areas. Basicly it will depend alot on your local towers. Believe it or not...ALL CELL TOWERS ARE LEASED FROM VARIOUS COMPANIES LIKE SONY ERICSON WHICH MAINTAIN THEM ALL ALMOST!!...therefore it is very dependent on the towers in your area which radios are likely to work if not the stock modem on the device. It depends on what lease and roaming agreements are in place in your region....again...I WORK ON PHONES EVERYDAY FOR SPRINT...know a little about all that stuff...trust me...i have people yelling everyday about not having this or that when most of it is the carrier hasnt signed an agreement with Kyocera or whom ever to support that device or the lease contract has expired and will be resigned in a few days....bottom line is ....if the phone has a radio chipset that supports multibands and frequencies it is almost always possible to do what ever you would like with it. As far as firmware lock....too funny...those do not work on Android devices as the chipsets were intentionally designed to be unviersal to all carriers to cut manufacturing costs...much like in automotives where Mazdas and Fords use the same parts...just a reference. Anywho....It really is possible...it just takes research and a TON of time sometimes but that is the point of hacking....most would have said the Xbox Kinect wouldnt have been able to been hacked or the Wii remote seeing as both those use internal chips that range in the thousands if sold for other purposes. Long story short....happy hacking and Thanks to all of you for a great discussion forum.
