Replacement phone with TMO bands also? - Captivate Q&A, Help & Troubleshooting

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.

Cool! Thank you.
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.

i wouldnt put much hope into it. you might get lucky in that the skyrocket works on TMo, but its doubtful. i have never seen an AT&T phone work on Tmo's 3g

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

http://forum.xda-developers.com/showthread.php?t=1299211
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=

How do i know which version of nexus one i have?

Hey there,
I recently had a htc desire, i loved it. However, i will be living in panama for a while, and it wouldnt be so sweet to only have edge as they run 3g on the 850 band.
reading on this page there seems to be 2 versions of the nexus one. one with quad band and one with tri band..
http://en.wikipedia.org/wiki/Nexus_One
Is there a way to know what is in my phone if i am holding one i am potentially buying?
It seems the developer version on sale now is tri band sadly.. so i cannot buy a new one..
They're both quad band GSM for voice and data up to Edge. The difference is for 3G data. AT&T and T-Mobile use different 3G frequencies.

Easier to just copy and paste the info then have the OP go to another site.
Pull the battery and look for the PB # which is located just below the IMEI, S/N, and P/N #’s. You should see one of two PB numbers:
PB99110: 850 MHz, 1900 MHz, and 2100 MHz such as AT&T in the US and Rogers Wireless in Canada
PB99100: 900 MHz, AWS, 1700 and 2100 MHz such as T-Mobile US and Vodafone in Europe

At&t + T-Mobile Merger Hurts Potential US G2x Buyers

Hi alls, I wish I had better news to bring. The good news is, as expected, the 2X runs stock Froyo.
Now the kicker: as you are all probably aware, At&t has gobbled up T-mobile. This means that when the transition is complete (expected a year to 18 months from now) At&t will drop T-Mobile's 3G bands to EDGE.
It may not affect some owners but for me, I usually keep a device until a big hardware refresh comes about- like a quad-core chip. I'm skipping the 2x for the Galaxy II or the Optimus 3D. I was on the verge of owning this...
Luckily the normal 2X do support UMTS 1900 (one of the 3G bands AT&T use), that's why I am consider buying it off contract from other place and use it on AT&T

Let me understand: do you mean the non-US version of the 2x, the off-contract US retail model, or both? Thanks!
It's been reported that the G2x will support T-Mo *and* AT&T bands:

So you can rest assured that T&A-Mobile will support the bands on your phone right through to the bitter end of HSPA over AWS, right?
Ha! I was spying Engaget & Giz all afternoon yesterday & the announcement was made @ Anand...! Thanks for the heads up!
at&t hasn't officially bought T-Mobile yet -_-
An acquisition of this magnitude might not even be legal, it has to be approved by the FCC and the DOJ
Just checked the specs on this new phone on the T-Mobile spec sheet that was posted on T-MO News ad and that device supports both T-Mobile and AT&T's 3G Networks. I had to recheck it over 10 times during the day in case it was a miss print and they are still posted.
Has anyone else found any news that is different???

Yes, this says different. (Dang it, I can't post links. Search on Engadget.com for "T-Mobile G2x lacks quadband HSPA+, shatters dreams")
That said, I'm still curious to find out if anybody else has tried the the 2X or the G2x on AT&T yet. I'm not smart enough to understand what the lack of 850 3G means. Is that an upload speed? So would I be able to download zippily on the 2100 Mhz band but my upload would take forever?

Further adding:
I'm interested in potentially buying the Optimus 2X (900/1900/2100 UMTS) not the G2x (1700/2100 UMTS). Anybody able to explain why the 2X may not work with AT&T, or share experience with it working?
The 2x will give you 3G on only the 1900 band with At&t, and not on the 850 band. So your 3G coverage will be worse than phones designed for the carrier. It will not get 3G on T-mobile.
You may as well just wait for the "Thrill 4G".

what are the speed test for this phone on tmobile?
and so if it dosent get 3g will it be getting edge?
Just in case someone finds this thread again, the G2X DOES NOT support *any* AT&T 3G frequencies:

[Q] ATT Nexus one on Tmobile

Hi everyone i tried searching but didn't come up with anything. I'm considering purchasing an unlocked nexus one on amazon and I'm not sure if its a tmobile or att version I have tmobile as my provider if i were to get an att version would i still get 3g access? I know if it was the opposite i there would be no access for 3g on att.
Thanks
I believe t-mobile's 3g is 2100mhz, which means the atnt one should work on the network.
I'd get a second opinion though, I'm more knowledgeable on Australian networks than US ones.
Ok thank you for the input, if anyone could confirm this that would b great.
The devices are completely independent of one another in regards to 3G. Cross network compatability only extends to Edge services.
Someone jump in and correct me if I am wrong, but I believe that T-Mobile 3G requires both the 1900 and 2100 frequencies to work (up & down link).
Rod3 is correct the at&t version will not work on t-mo and the t-mo version will not work on at&t, in respect to the 3G that is you will still get edge either way.
Although as far as the both 1900MHz and 2100MHz I'm not sure about that but it's possible, anyone care to add some info.
EDIT: Just Googled it and it's 1900MHz for 2G and 1700MHz/2100MHz for 3G encase anyone is interested.
Dude, thanks for the correction. I knew there were 2 frequencies for 3G and I just picked one off the top of my head. Now that I think about it, yeah 850 and 1900 were for 2G.

[Q] HTC Vivid on Tmobile 3G/4G?

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.
Sent from my Lumia 900 using XDA Windows Phone 7 App
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.

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.

[Q] HSPA+ on T-Mobile

Hi, if I were to get an unlocked Galaxy Note GSM, would I have to do anything fancy to get HSPA+ (4G) to work on it?
Would it be as easy as to pop in my SIM card and go to work like on any T-Mobile device?
Please respond back soon because I am trying to buy one tonight off a guy on craigslist, I don't want to get ripped off!

International Version Galaxy Note N7000 doesn't support 4G [LTE] Network.

I don't want LTE. I want T-Mobile HSPA+. Will it work by putting a sim card in it?
then you'll need to wait until T-Mobile repurposes their 1900MHz band for HSPA+. I don't know if they're doing it for the whole country, but it has started to happen in some areas already
But it is as simply as popping in my sim card?

If you're lucky enough to be in the right area, yes
Well it's just to make phone calls. It's okay if I don't have internet connectivity everywhere. I am going to be buying it off a guy on craigslist in a place where I normally get service... he's selling it to me for only $450. Kind of nervous that it's a fake/scam.

Any idea what areas? Mine arrives tomorrow, live in PHX.
Sorry but don't count on anything more the edge on TMobile, unless you are really lucky and you are in a 1900 Mhz area. If you want TMobile buy an AT&T Note and you will have to do some hacking to get the radio working on TMobile.

This.
Don't expect the entire US to get 1900Mhz 3G on tmobile, since the radio spectrum is subdivided differently depending on the cities.
Mostly the west coast and pennsylvania so far

So there's no such hack for the international note? I don't understand how an internationally unlocked phone doesn't support USA GSM highspeed. My T-Mobile G1 supports HSPA+.
Does AT&T 4G work with the international Note? I have it now and I'm only getting 2G. It's god awfully slow.
If you want to buy Note N7000 you will get EDGE on Tmobile.
No 3G
No 4G

On AT&T does it get 4G? There will never be a hack like there was on the AT&T model?

I'm on the Left Coast, maybe should l see if 1900Mhz is in my area.
To be honest, I'm actually happy with me my broadband sim on AT&T. I just had the LTE code added to my account and I got a little boost in speed on HSPA+. I'm seeing 8Mbps down and the speed seems more stable then before. It does seem to be ramping up to max speed a little slower and I have a firm upload cap at about 1Mbps, before I occasionally would hit 1.5 Mbps. HSPA+ does seem to do Skype and Google Voice pretty well, I've been managing to use a a data sim as a phone quite successfully.

The international Note gets HSPA+ on the AT&T no problem. I'm currently enjoying my H+ icon with my Red Pocket sim card.
The International and American Notes have entirely different hardware inside. The American Note has a pentaband radio that can be reflashed for either AT&T or T-Mobile frequencies. The International note does not.

Wrong. The International Note has a pentaband radio. It's the same modem as the Galaxy Nexus GSM.
It just so happens that the AT&T Note shares the almost the same hardware with the T-Mobile S2 which makes it easier in terms of getting the modem from the T-Mobile S2 to work on the AT&T Note. This is why how they got the hack working on the AT&T Note.
This DOES NOT WORK on the Int Galaxy Note as we are running an Exynos/Infineon chip/baseband.
Okay. Instead of arguing with each other about who can spout-off the N7000's and i717's specs most accurately, why don't we just give the OP a simple, comprehensive answer?
Okay. To answer your question, the N7000 (International Note) will work perfectly fine on T-Mobile US. Phone calls, SMS messages, and data will all work perfectly. The issue, however, is not with the services you can get, but the quality of the services you can get. Even though the N7000 is an "international" GSM device, T-Mobile uses irregular frequencies for it's HSPA+ network. Specifically, instead of supporting HSPA+ on a single frequency, T-Mobile's HSPA+ service is divided between 1700MHz and 2100MHz in what is referred to as 1700/2100 AWS (Advanced Wireless Spectrum). Because AWS is a rare and unusual implementation of HSPA+, almost no "international" phone models support it. In most cases, only phones meant specifically for North America support it. What this means, simply, is that the N7000 will never be capable of using T-Mobile's HSPA+ network (unless you have the rare privelege of being in a 1900MHz HSPA+ area).
Now, just because the N7000 won't let you use T-Mobile's AWS HSPA+, it doesn't mean you can't have your cake and eat it too. Granted, it is a small concession, but the i717 is a "more than adequate" smartphone and will (with some minor modification) make neat work of connecting to T-Mobile's AWS HSPA+ network. Preliminary speed tests even suggest that the i717 is faster on T-Mobile's HSPA+ network than the N7000 is on AT&T's HSPA+ network. So, if you're willing to sacrifice the added speed and power the Exynos SoC offers, you could gain T-Mobile 3G compatibility and NFC to boot just by opting for the i717; which, I might add, is only $649.99 off-contract at AT&T.
If I can help clarify any confusion or answer any questions, please feel free to ask. I know there are a lot of people out there who feel very strongly about which version of the Note is superior. However, it's my opinion that when you come across someone who's undecided, you should simply give them the facts and allow them to make their own decision. Passionately mixing facts with opinion only serves to further confuse things.

That is a really nice post. Too bad I already got the GSM Note. Trying to sell it so badly...
BTW unlocked at AT&T is $650

You're right. Sorry. I fat-fingered it. It's corrected now.

i live in boston and decided to call tmobile about the 3/4g coverage. supposedly the 1900 band is now in use for tmobile 3g. so i cant get 4g but i could get 3g...now i have to hunt down a non att branded note. the map the lady referred to was dated june 6th 2012 so im hoping her stuff is right.
hate to buy a not and still be stuck on edge.
