Thanks. Would be really great if someone with an unlocked vibrant could check this out. Really want a Galaxy S phone and wanted one of the American version since they come with the 16gb on board. the thing is I have just about a week to figure out this since I will be in the States next week and would want to buy one then and get it unlocked.
[Vibrant General] reuthermonkey:
And yet, amazingly, it does.

Funny how that works.
[Vibrant General] bigjm23:
that sucks still guess it is edge then!!!
[Vibrant General] heygrl:
Ugh

It's really not very hard to understand

I didn't get on AT&T's 850 3G network because you guessed it, No 850 3G antenna support! You will still get 1900 3G, just no 850 3G. It's not something that needs to keep getting dragged out for over 100 posts!!!! Insanity
[Vibrant General] reuthermonkey:
I hate to use an already overused internet meme but...

you're doing it wrong.

Alright, I went through and tested this out to verify. Let's not forget, I'm the one who said that techspy was full of crap when he said the phone supported 1900. Now not only am I convinced of it, but it's quite clear that this phone also is fully 850 functional too. Whether you choose to ignore the evidence is entirely up to you. Ignorance is always an individual decision.

Here's what I did:

1. I set the phone to WCDMA only. By default, it's set to "[1] Automatic" in the service screen.

2. I set the phone to ONLY use [8] WCDMA 850 (FDD V)[*] in the Combination Bands screen.

3. I went to the network selection screen to search for bands. Remember, GSM is disabled.

1900 is disabled. This is only searching for 850 WCDMA. Notice the signal up at the top when ONLY 850 is enabled.

It only finds ATT. NO TMO AT ALL. (if GSM were enabled, TMO would show up; If other WCDMA bands were enabled, TMO would show up).

Since I'm not going to get my phone unlocked any time soon, I can't test it on ATT, but this IS reproducible for anyone who is already going to use ATT.
[Vibrant General] heygrl:
Let's see a screenshot of the phone on AT&T and what it says under "Basic Information"
[Vibrant General] reuthermonkey:
What about "I don't have an ATT SIM card" and "i'm not unlocking my phone anytime soon" is so difficult to understand?

And do you understand at all that T-Mobile doesn't have a 3g roaming agreement with ATT, and thus I can't actually register on their 3g network?
[Vibrant General] Welshy992:
Can't we all just get along?
[Vibrant General] heygrl:
You don't need an AT&T sim card to get on their network. You won't be able to make calls, but you will be on the network with emergency only access. You just took a screenshot of this and showed it to everyone. Did you miss it?

Did you not see the bars of service when you we're on AT&T? Like I said, put the phone on 850MHz 3G under BandSelection EXACTLY like you did before for those screenshots, wait for the bars to come up like they did for those screenshots you took and go back into the service menu and take a screenshot of the basic information menu.

It should say 850 WCDMA and not 1900 WCDMA - IF it was on AT&T 850, which it isn't.
[Vibrant General] ntellegence:
I have no ATT friends so I can't do this. It is legal to unlock phones. Unlock a vibrant put your friends sim in and let us know.
[Vibrant General] rockin69:
unlock code

i tried to get the unlock code from that one you recommended.....is it the same code for all tmobile galaxy vibrant phones and if so can I just buy it from you...thanks....ron
[Vibrant General] werdz2:
Guys, I called TMOBILE yesterday night in regards to receiving an unlock code. This morning I received the email from TMOBILE with an unlock code for my IMEI. I went ahead and popped in an ATT SIM Card from friend and entered the appropriate code as per the email. It went through its process and said that my phone was network unlocked successfully.. I was then able to connect to ATT 3G service without making any changes. This is Miami FL.
[Vibrant General] x3gypxtianx:
Yeah, I'm on AT&T and can't get off the 1900 WCDMA band even when I make it 850 only. Basic Information still reads WCDMA 1900 Band 2. It got my hopes up for a moment, though.
[Vibrant General] :
The Vibrant was known to be a true quad band phone, it was stated a couple of months ago, no need to doubt the OP, it's in the specs.
[Vibrant General] raduque:
reuthermonkey, i tried your instructions, but when I attempted to enable the WCDMA 850 band in the WCDMA Bands menu, I get the same screen heygrl gets: "Menu not exist press back key".

I can enable 850 in Combination Bands menu, but with only 850 and 1900 enabled, I get "No Service" in the Debug Menu's "General Information" menu.

Edit: I also can't figure out how to remove selections in the Combination Bands menu, I tap one and it just selects it.

Edit2: I figured out how to get rid of the "Menu not exist" message. You have to go to Combination Bands and enable 850 WCDMA there first, then go enable it in WCDA Bands. But I noticed if you select one of the other bands, then try to re-select 850, the "Menu not exist" message comes back.

General Information shows "1700MHZ" in the General Information menu, even when 1700 is unselected.
[Vibrant General] zerosource:
So the 850 doesn't work then.
[Vibrant General] heygrl:
It does /not

Never has and never will
[Vibrant General] applebook:
I am just pleased to read that it has 1900, which suits us Canadians just fine ;-) Thanks to OP and Heygrl.
[Vibrant General] juddpwr:
as was stated many times in this post being a "quad band" phone has nothing to do with the 3G frequencies it supports....
[Vibrant General] :
Except for the fact that the quad bands that it supports match up with both att and t-mobiles bands for 3g....
[Vibrant General] juddpwr:
that statement makes no sense.... 2G freq. support != 3G freq. support

and no, the "quad bands that it supports" [850 / 900 / 1800 / 1900] do not at all match TMO's 3G frequencies (1700 / 2100)

take a look at this:

here's the data from gsmarena for the vibrant:

** dang, says new users can't post links, so i'll have to paste it in **

General	2G Network	GSM 850 / 900 / 1800 / 1900

3G Network	HSDPA 1700 / 2100

Announced	2010, June

Status	Available. Released 2010, August

as illustrated there are separate lists for the 2G and 3G freqs.... thus the vibrant is a quad-band GSM, tri-band 3G (since the OP proved it supports UMTS 1900)

the iPhone 4 for example is listed as a quadband 3G (and quadband GSM) phone, but I've seen it referred to as the second ever pentaband 3G phone (google it on engadget)

General	2G Network	GSM 850 / 900 / 1800 / 1900

[Vibrant General] :
So you're telling the T-Mobile Vibrant doesn't run have 3g on T-Mobile.
[Vibrant General] p()()pypants:
Purely speculation and haven't finished entire thread yet or know any bit about what technologies/bandwidths go into hspa+.... but I think that although vibrant isn't Supposed to be an hspa+ phone that maybe this additional bandwidth its in fact to help it "halfway" take advantage off the nw extra high speed network being released by t-mobile.... Again completely uneducated guess

Pooped from my Samsung Vibrant using XDA app...

Dont mind the skidmarks...
[Vibrant General] lqaddict:
Nope TMO's 3G UMTS freq's are 1700 and 2100. It so happens Vibrant boosts UMTS 1900 as well. I did test it on ATT network with my unlocked Vibrant in NYC and it gets 3G speeds here, if you happened to be in the area where ATT UMTS 850 MHz is prevalent you are SOL with the Vibrant - EDGE only.
[Vibrant General] p()()pypants:
Mmmk, not doubting anything stated in the thread or what you just stated but is umts the same as hspa+, t-mobile's newr high speed network set to compete with sprints 4g network???

My post was based purely on what I quoted namely italicized, what would be the real purpose of even placing a typically unused by t-mobile bandwidth on its phone other then possible roaming situations? (remember there is the option to turn on data roaming on these android phones and so maybe that's really the only true functional reason for samsung/t-mobile to even put an att 3g bandwidth on their phone)

[Vibrant General] os2baba:
I mean seriously! This guy gives some great info and it was okay to question it since it seemed that there was a possibility of user error, but after he has repeatedly answered questions, responses like "I call BS" and "I don't care what pictures or videos you show, I don't believe it" are enough to put the backs up of anyone.

Anyway, Thanks for the info. I won't be using it since T-Mobile works just great for me. But it's good to know.
[Vibrant General] os2baba:
When the EVO was being tested., my friend who works for Sprint told me that it has a GSM slot as well. I was so kicked since I really wanted to buy the phone, but I travel a lot internationally so I need a GSM phone. But when the finally released the production version, they had removed it. Sprint has a few phones that have a GSM slot as well. But none of them are Android phones.

I don't know how much more expensive it would get to add CDMA and worldwide radio frequencies. I suspect not a whole lot and it would dramatically simply their production line. It's like the cheap no-name Chinese DVD players. They always played everything I threw at them. Meanwhile my more expensive LG/Toshiba/Sony were always very finicky!
[Vibrant General] moSess:
Question

Can you get the opposite as well? Can a Captivate get 3G on T-Mobile?
[Vibrant General] lqaddict:
Unless you have an unlocked Captivate - there is a bloody thread in Captivate forums dedicated to that with bounty and the whole 9 yards - no way to tell.
[Vibrant General] reuthermonkey:
TMO only uses UMTS Band IV 1700. When 2100 is listed, it's referring to Euro UMTS Band I 2100. All TMO phones happen to support UMTS 1700 and UMTS 2100. If you're going to correct people, get it straight. Yes yes, I know that UMTS Band IV uses frequencies in the 2100mhz spectrum, blah blah. When referring to network support, it's the bands that are listed on the phone.

Otherwise, you're correct: The phone supports Band II for ATT, but doesn't support band V on ATT.
[Vibrant General] p()()pypants:
So do we even know of our vibrants are using those 1900 towers RIGHT NOW with a tmobile card in? I'm sure that if not someone can figure a way for us to access it all the time to thicken up our 3g coverage.... right???

Pooped from my Samsung Vibrant using XDA app...

Dont mind the skidmarks...
[Vibrant General] reuthermonkey:
Huh?

If you're using tmo, all you need is 1700. 1900 is useless when you're using a tmo sim card...
[Vibrant General] jonathan3579:
I'm going to chime in just to throw this out there though it's not directly related.

When using a iPhone 3G on T-Mobile's network, it says 3G though we all know it's not getting 3G... Isn't it possible the same thing has happened here?
[Vibrant General] techspy:
Well, I guess now it is known that the Vibrant can now indeed work on ATT with 3g. Just saw that this is "mainstream knowledge" now.

http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/

So for all of you that kept saying "BS" etc, even after I posted picts, videos and answered all the questions you had... GFY

It is nice when the smartasses that think they know everything get outed....ah vindication..
[Vibrant General] gsvnet:
That's not what is happening here, I've tested it out and got very good speeds (2-3mbps) with an AT&T SIM. I need to stand outside to get 3G where I'm at though, as 1900 is very spotty on AT&T indoors (tower is likely further).

I'll admit I was one of the people who thought this wasn't possible. I'm pleasantly surprised to see that it is, though.
[Vibrant General] Elite GunnerX:
It works. I get 3g speeds on my unlocked samsung vibrant on at&t

Will post pics if requested
[Vibrant General] :
no but the bandz and the hurtz!

I think it's quite sad how the situation in the US in regards to cell phone networks.
[Vibrant General] voghan:
I tried an at&t sim in my phone today and got 3g. I bought my phone off contract and discovered tmobile has no 3g coverage at my work. I'm really tempted to ditch tmobile for at&t but am worried it won't work else where as well.

[Vibrant General] Superfrag:
Well I just unlocked my Vibrant and put in the ATT Simcard, and it worked fine.

BUT, there was no 3G, just as I expected, since the place where I am, (Erie, PA), ATT's 3G is 850Mhz UMTS only. My BB right next to it on the same sim card has 3G. So the Vibrant definitely does not have the 850Mhz band, but it does have the 1900Mhz band.
[Vibrant General] heygrl:
T-Mobile has 3G in Erie, PA?
[Vibrant General] reuthermonkey:
according to their coverage map they do
[Vibrant General] Superfrag:
Search this zipcode ; 16563. There is only EDGE in that area, bad coverage too. Right now I'm using ATT EDGE on my Vibrant cause its better than the TMo EDGE. (That zipcode is of the Penn State Behrend Campus where I'm living).

If I go into the city then yes the TMo coverage is great with fast 3G, but the moment I leave the city the coverage is bad. :(

I called TMO when I got my Vibrant to request an unlock code. I provided the phone IMEI # to them.

In 2 days they sent me an email with the following instructions:

- Insert a NON T-Mobile SIM & turn Device on

- The Device will automatically prompt you to enter code into an empty field.

- Tap in the empty field above the "Unlock & Dismiss" options (this will display a key pad on the screen).

- Using the key pad input the Unlock Code provided by T-Mobile.

- Press the Back button to remove the keyboard from screen.

- Tap the "Unlock" option; handset should display "Network Unlock Successful".

I inserted my ATT blackberry SIM and went over the instructions...
[Vibrant General] Veetus:
Ok but what frequency are you getting that 3G service on...?
[Vibrant General] lqaddict:
I am pretty sure it is UMTS Band II 1900MHz here in NYC.
[Vibrant General] cparekh:
If it's with a Vibrant on AT&T would it not have to be 1900?

Why wouldnt you just use the SGS unlock tool?

Free download, and shows you the unlock code for your phone.

The galaxy S series phones have the unlock code stored in them.

You guy are crazy all this conversation for nothing download the app from the narket its called galaxy s unlocker and run it it will give you the code. And yes it works att 3g . I got the youtube video search samsung vibrant at&t u will see. It runs better then any phone I had with att.

I called tm and guess what they gave it to me for no charge and no hassell . You should try that some time

did u buy the unlock code from ebay???? u can download SGS unlocked app for FREE from android market and get the unlock code for your fone within seconds!!!!

[Vibrant General] ivuso2000:
how does it work for you? i just unlock my vibrant plug in att sim card and 95% i am able to pick up only att EDGE!!!
[Vibrant General] ld006:
that's cause you either a) have poor reception where ur trying to pick up 3g so it switches to edge, b) you're in an area that has no 3g coverage or c) you are in an at&t 3g area that is using a 3g frequency that the vibrant doesn't have so it switches to edge
[Vibrant General] AlexSochi8:
Sounds like a win!

To people that dont understand or are a lil confused... The vibrant is one of a few phones that works on T-mobile's 3g and on ATT's... it works on both bands :) thats the awesome thing about it... Like me I have a flex plan so I bought the phone for around 600 but if i ever need to go to att I can :) or anyother provider that uses a sim card
[Vibrant General] ajftl:
Yea and no 3g. Suck ass

[Vibrant General] eortizr:
The Vibrant only works on AT&T 1900mhz band... if you live in an Area where AT&T just recently got 3G coverage... is 99% possible that AT&T is using the 850mhz band and the Vibrant will not get 3G.

I think I can use a little help.

I tried to update my SGS from I9000XXJF3 to I9000XXJF7.

I followed the steps with Odin etc etc....bu now my device does not reboot anymore! It only shows a white screen with blue letters "AT&T WORLD PHONE".

I can not get the device in download mode or recovery mode anymore. When I'm pushing volume down + home + on/off button, it shows the same white screen.

What can I do now? I hope I didn't brick the device....
[Galaxy S I9000 Android Development] Oooch:
Can't even get into the menus to flash? Wow.. I don't think you can fix that.

volume down + home + on/off button = White screen..

AT&T...

Mate, did you flash Captivate with I9000 firmware? They are, kind of, like 2 different phones...

You can use I9000 firmware, but only if you use standard modem file (that from what I briefly read, I can be completely wrong).
[Galaxy S I9000 Android Development] Darkstriker:
Did you remove the battery and force a fresh boot into download mode?

And yeah. Are you sure you don't have a captivate and not a SGS i9000?
[Galaxy S I9000 Android Development] Ancient_One:
Remove the battery which might force a reset of the device.

Once you put the battery back in see if you can get into Download Mode again then go through the reflash firmware again. Make sure your using the correct files.

Yes, after hours and hours of studing the problem I can confirm:

By mistake, I was using Odin for Captivate , on trying to bring back to life my i9000.

Now, what can I do? There is any chance to get the phone in to the download mode?

Thank you very much for your time and patience...
[Galaxy S I9000 Android Development] Sputnik.:
OK you used the wrong ODIN version... but I thought ODIN doesn't touch the bootloader? So if this is also correct for the captivate version of ODIN, I think there is still hope.

Maybe you can find something useful in the captivate forum.

Same Problem Here This is My most Stupid Firmware Flashing ever made.

Please Help

cant find any info in the captivate forum
[Galaxy S I9000 Android Development] Ancient_One:
Download the correct ODIN, PIT and Firmware. Set them up on your computer.

Remove the battery, SIM and SDCard from your phone. Wait a few seconds.

Re-insert your Battery only.

Put the phone into Download Mode - volume down + home + on/off button

You might need to try this a few times I don't always get it first time.

Connect the phone to your computer by USB and confirm ODIN see's it.

Then flash the firmware again.

Wait for reboot then switch off and re-insert your SIM, SDCard.

Should be right now. Fingers crossed for you.

I have try in Captivate topic maybe find something usefull, but nothing. They us a light different method to get in download mode, but it doesn't work on my phone.

Always I get the same white screen.

I really don't know if the battery is charging in this white screen.

I keeped pressed for about 1 min and nothing. Same white screen turning on and off at 4-5 seconds....

I think there is no solution for this...Just to buy another new phone.:D
[Galaxy S I9000 Android Development] mbr01:
He,

Was just looking up a picture of the Samsung Captivate. I noticed it has only touch buttons, and no hardware home-button like the regular i9000. Maybe the key combination to get into download mode has changed due to the flashing.

I read in the captavate formum the combination is

or

Hope this helps.
