My service provider Cable&Wireless Panama uses 1900 band for 3G, but I NEVER, NEVER EVER get anything but EDGE data... ever.
I have my phone set to "GSM/WCDMA (Auto Mode)" in Network settings, but I could choose one or the other.
Which should I pick? I don't know what's up, but I can never get 3G and I know that the Vibrant supports 1900, which they use for 3G.
They tell me that 3G should appear there as an option, (at least on the Galaxy S i9000 that they support, but it doesn't on the Vibrant.
Can anyone give me some advice? I'm really stumped, because I was thinking it would work fine. I'm unlocked, Rooted, running Bionix-v but I've never been able to get anything but EDGE data and they say I should have 3G in most areas, but I've never even seen it once.
Not trying to be a jerk here, but are you absolutely sure your carrier uses 1900MHz for 3G specifically?
If you search for "List of UMTS networks" on Wikipedia, it lists Cable and Wireless as 850MHz. Another thread on androidforums.com titled "i9000 No 3G after update" talks about getting an i9000 working on 850MHz for Cable and Wireless.
Also, just to clarify, you are using the T-Mobile/American Vibrant?
Hope you figure it out.

Well, I was just on the line with them and asked specifically and two different reps (I tried twice) confirmed it was 1900 for 3G, so I do think it is.
They could be wrong, I guess, because most customer service reps are idiots throughout the world, but I don't know.
change your APN.
I bet it's set to epc.tmobile.com

No, it's connnecting, and I get data via EDGE, as I said, the APN is correct:

I just don't get any 3G signal... ever, but according to CW, I should if I use 1900, which the Vibrant supports.

again, Cable and Wireless doesn't use 1900. They use 850.
If you're stuck with the Vibrant, you might try Movistar? Looks like they might support both.
I know these aren't the answers you wanted to hear though. Sorry man.

I appreciate the help, guys.
I still find it confusing that the phone they support officially (they sell the i9000 here for like $800US) is listed as supporting the same 3G bands as the Vibrant, including 1900, which they quoted to me twice, but somehow, my Vibrant won't connect to 3G, so probably they are just idiots, as usual.
I might have to go with another carrier. Problem is that CW is the cheapest, by almost half. I guess you get what you pay for.
Movistar 850 pana..no tienen 3g son puro bulls**t,
Digicel y Claro si estan levantando 3g con la banda 1900.

Hey donalgodon, I got the exact same problem with my Nexus S, same provider, same network configuration. Did you figure it out? I sent you a pm, let me know.
I was just reading this on Wikipedia.
In the bands section of T-mobile and thus their phones, 2g is supported by 850 and 1900. 3g is tied to 1700. I thought I had read it differently before but upon checking up on this once again (just now) that is what I have to offer. So I would assume if your carrier doesn't use 1700 for 3g then you would not ever get 3g.

The Samsung Vibrant supports 3g on UMTS Bands I (2100), II (1900) and IV (AWS/1700).
If your carrier uses any of these bands for their 3g, you will get 3g.
If your carrier uses the 850 band for 3g, you will not get 3g.
Donalgodon's carrier uses 850. That's why it's not working.

It's not how widespread it is. They use different frequencies so your phone won't pick up the ATT 3G signals at all. Edge is 2G.
But I've seen one person on the forum claim that he did it. You can pm him/her on how to do it.

I am on an unlocked Vibrant right now. I live in the baltimore area and I am getting full 3g on a friends borrowed att sim. I get faster speeds on his att than I get on my own tmobile.
When I unlocked my phone, I used the wife's SIM card on my Vibrant and was able to get 3G as well. It registered without any issues.
New york city is also all 1900mhz. I am chugging along at a healthy 4300kbps according to mobilespeedtest. I think that is faster than the 3g spec allows so I am starting to doubt that website a bit.

HI,
Can you explain how you get UTMS / HSDPA 850 on the Vinrant? According to the specs at xda
It doesnt officially support that, but over at howard forums (sorry cant post lins as a new user):
1666323-USING-SAMSUNG-T-MOBILE-VIBRANT-T959-on-WIND-MOBILE.....IN-CANADA
it seems it is an option in the service menu. Have you tried UTMS850 (as opposed to GSM850) and can confirm it works. Its relevant in Australia as the best coverage NextG network (Telstra) operates on UTMS850
Cheers Chris.

Try dialing

choose option [4]Combi Bands
Choose option [8] WCDMA 850 bla bla
Choose Add WCDMA 850 bla bla
If the chip is capable to work in that frequency it will work. There are mixed reports but it is the way to fix it

Actually, the rumor going around the internet that you can only use At&t 1900mhz on the Vibrant is false.
The vibrant can also utilize wcdma 850mhz. So you should have no problems picking up both 3G signals from At&t.
I will work on making a how to video that shows how to make the vibrant pick up the wcdma 850, takes litterly 2 minutes to do.
Remember, you might run into other annoying problems such as setting up visual voicemail to work with At&t.

Umm interesting thread, similar to what we are doing.
So are you saying you are not able to pick up the wcdma 850 (FDD V) band? We set this up on a friends phone, with his At&t sim, it works.
Can you try setting your phone to wcdma 850 only, and drive to a location that has 850 signal, then check under basic information, you should be getting at&t 850 3g.

Dear Vietphunguyen, there seems to be controversy. We know for certain the vibrant can pick up att 3g signal using 1900 band, but the question is, what about 850. Me and a friend believe the vibrant can also get 850, but that link the other poster provided is something to note also.
Be safe, don't purchase the vibrant yet, until we test this more. 2 make sure you can pick up both 1900 and 850 bands.
I dont know much about the Vibrant just yet, but if its anything like the iPhone on TMO's towers, it might not work. The problem was with ATT using a single band for 3g (1900mhz) to send the recieve but TMO uses 2 bands, 1 to send and 1 to recieve... If this helps at all I dunno! lol

Thank you, just to clarify, for people visiting this thread.
At&t uses 2 differend 3G bands, one is 1900mhz and the other is 850 mhz. At&t is starting to implement 850 towers. Naturally, you would want a phone that picks up both bands.
Now, we know for CERTAIN, the VIbrant will 100 percent pick up At&t 3G 1900mhz signals. The question is, which we are uncertain of, will the Vibrant also pick up 850mhz band 3G signal, incase you hapen to drive to an at&t area that only has this band.
clearer?
[Q] Do we know the extent of the AT&T-friendly UMTS hardware in the T-Mobile Vibrant?
So as a lot of you know, the T-Mobile U.S. version of the Samsung Vibrant turned out to have hardware support for AT&T's 3G. But from reading user comments, it sounds like the T-Mobile Vibrant only has UMTS 1900, and not UMTS 850 as well. Obviously this isn't a problem if you've only got 1900 in your area, but I'm pretty sure we do have UMTS on 850 in my city.
I'm wondering if anyone with the T-Mobile Vibrant has tried using the extra 3G band(s?) and can confirm which are present. Is it 1900 and 850, or just 1900? Further, does anyone know how can I check to see which frequency AT&T provides 3G on in my city (short of relying on the clueless CSRs at my local retail store)? I've got a buddy with a Nexus One on AT&T, is there a quick way for him to see what frequency the UMTS tower he's connected to is using?
In the interest of completeness, I'll cover the questions that I'm sure will get asked so that folks don't **** up the thread with them.
Why not just get an AT&T Captivate?
Handful of reasons. I prefer the Vibrant's aesthetic, but more importantly because AT&T doesn't have T-Mobile Vibrant IMEIs on file. This means you can add and drop data at your own discretion instead of being required to use it, and it also means that their system will treat it as a dumbphone. Definitely a perk.
Why not just get a Galaxy S Vibrant from Bell in Canada? It definitely has 850 and 1900.
This is what I'll end up doing if the T-Mobile one doesn't work out, but it's a pretty big pain in the ass to get Canadian phones shipped down here whereas the T-Mobile version is readily available. Also, no warranty!
Thanks guys.

It doesn't work on WCDMA 850. Doesn't support it. Try selecting it only and put a AT&T sim in and see if you get 3G. Yea you won't, then try selecting 1900 only and what happens? Yea exactly.
Well, I dont have one in front of me to experiment with my AT&T and T-Mobile SIMs, Im just going off the side of the box and whats listed in the menu (both say 850). I currently have a Captivate and a Fascinate, but Im looking into getting the Vibrant instead for a number of reasons so I was just poking around. Sorry if I was passing on bad info.
~T.J.
EDIT: I thought I read of some people getting it to work on 850, but that could be wrong. Im looking again... Could it be there just isn't 850 coverage where you tried it and instead was 1900 coverage? These are OLD maps though...

Because the T-Mobile 3G network in the U.S. is listening for 3G data in the 1700MHz and 2100MHz bands, it’s the only U.S. network with which the Nexus One phone can communicate. AT&T’s 3G network listens for phones transmitting 3G traffic in the 850 MHz and 1900 MHz bands, which the Nexus One cannot do. All it can do is send 2G traffic in those bands, so it does, making a slower data experience for those using the Nexus One in Ma Bell’s mobile network.

Just because the it's listed in software doesn't mean it can work. The Fascinate is a CDMA phone and your gonna tell me because you see the bands listed in software that it will work on a gsm network? Really? Either way I'm not trying to get you down. Just saying if that were possible, it would have been mention already. To conclude though, it all comes down to hardware support, the software is just mirrored on all galaxy s phones. The Vibrant only does 1700/1900/2100 for 3G. The 850 band would have benefit you better for in building support, but it's not supported.

Thanks for all the responses, guys, I really appreciate the thorough feedback.
Sounds like 850 is a bust, which is really disheartening. There's loads of T-Mobile Vibrants on eBay in the $340-380 ballpark, but it's going to cost closer to $500 to get a Bell Vibrant down here.

No, and this is the case for every AT&T device in existence to my knowledge.

How is that an exception to what I'm saying. The T-Mobile version is not a device sold by AT&T, and is, by definition, a device sold by T-Mobile.
It's always been a bit easier to get T-Mo phones to work on AT&T - a number of them support the AT&T bands. But it's never been easy (and with the possible exception of the Skyrocket, never even possible) to go the other way without losing 3G.

NO
the i777 does not support the required bands for accessing TMobile's 3g/4g network.

That would be the obvious answer based on the published specs, but I found an unselected listing in the hidden modem/ band settings for WCDMA 1700 MHz (Band IV) on my i777. I don't know if it works, but it's listed. From the phone keypad on the stock version, type in *#2263# and then look under Combinations. The phone lists 7 different GSM/PCS/WCDMA frequencies and only the obvious 5 are selected.
Anyone with an unlocked i777 on Tmo want to try it out?

Even though there is a setting for wcdma on 1700, it doesn't seem to make a difference. Still stuck on edge.

WCDMA is 2G/Edge technology. HSPA is 3G/4G technology.
maybe it will possible if we can flash a T-Mobile midem on out phone with out breaking it

Unlikely. Unless the phone has the hardware support for it.
I found out after extensive research on the Nexus One, that even though the radio chip inside it supports both frequency sets (pentaband, I suppose); the power amplifiers were only connected to certain frequency outputs, depending on the carrier it was advertised for. Which means even if I flashed a T-Mobile radio, the signal wouldn't be strong enough to get outside the case of the phone, let alone to a cell tower.
Your best bet is with European phones, as I believe they use the same frequencies as T-Mobile (since they're owned by a euro company).
Someone should confirm, but I would guess that the I9100 will work on T-Mobile with 3G.

No.
Tmo's AWS band its an odd ball. Only certain Canadian Carriers use the same band.

No, WCMDA = UMTS = pure vanilla 3G.
2G = GSM/GPRS
"2.5G" = EDGE
3G = vanilla UMTS (WCDMA)
3.5G = HSDPA
3.75G = HSPA+
3.9G (it's not really 4G) = LTE
true 4G = LTE Advanced
Most phones, even if they support advanced modulation schemes (HSPA, HSPA+) will list the band support as "UMTSxxxx or WCDMAxxxx"
I heard (it's actually confirmed, can't find the article), T-Mo has the same 3G bands as AT&T in some remote part of the USA, I think somewhere in Washington state, not sure though? The OP might want to move there

That might explain why the Vibrant apparently supported one (but not both) of AT&T's bands.
As I understand it, unlike the N1, the international HSPA+ Galaxy Nexus is full-blown pentaband.
Tmo has roaming agreement with at&t. So it is possible in places there is no tmo tower, your tmo phone could roam to at&t tower without showing the roaming sign.

I live in the Chicago Suburbs, and I got my brand-spanking new International Galaxy S3 [GT I-9300] delivered by Expansys today ($778.97 plus taxes). Color is "marble white", and it's a thing of beauty; I just love the phone!
However, when I added the "Straight Talk" (AT&T) SIM card and completed the setup process as described, I wasn't even able to download Apps from the Play store... because my connection is too slow!
I verified twice that all my APN settings are correct, but all the speed I seem to get is "Edge" (phone is displaying a tiny 'E' in the status bar) with max speeds of 212 kbps UP, and 140 kbps DOWN... - WHAT A JOKE!!!
My question: what am I doing wrong?
I did my due diligence before buying the phone; making sure that AT&T delivers decent speeds on the frequencies that the I-9300 can pick up.
Just for comparison's sake, the GT I-9300 covers the 850/900/1800/1900 MHz bands for 2G GSM/GPRS/EDGE, and 850/900/1700/1900/2100 MHz for 3G UMTS/HSPA+.
According to AT&T's website, they primarily use the 850 and 1900 MHz bands here in the US - which means, I should be able to get HSPA/HSPA+ speeds around here.
No such thing, I'm afraid.
Any idea what the problem may be?? I have searched for answers in this Forum already, but came up empty...
Sounds like you could be in a 3G black area like where a few metres either way could give a 3G signal, so just try your network in another phone and you'll know.
Maybe you got the T-Mobile version of the sin card by mistake

Thanks for the input!
I'm pretty sure it's an AT&T card, as all the APN setup instructions that came with it are for Cingular/AT&T..
Looks like I have to give Straight Talk a call tomorrow; hoping that this can be figured out...
Sent from my GT-I9300 using xda premium
The APN setting were correct, but -apparently- I wasn't familiar enough with the "Mobile Network" setting... since there was no indication of it in Straight Talk's setup instructions and I never had to mess with it before on my previous phones...
Anyways...
Go to SETTINGS > MORE SETTINGS > MOBILE NETWORKS > NETWORK MODE:
Select select "GSM/WCDMA (Auto mode)"
In "Network Operators" (right below) press "Select Automatically"
I also made another change that I read about when searching for a solution. And even though it is believed that it does not solve the problem, it helps to "speed up" things... by whatever margin that may be:
In "ACCESS POINT NAMES" (part of "MOBILE NETWORK" menu):
Change the "PROXY" from proxy.mvno.tracfone.com to 66.209.11.33
As a matter of fact, 66.209.11.33 is the same address as proxy.mvno.tracfone.com, but the phone/service does not have to resolve it anymore - as it already is 'translated'. This is believed to make things a bit snappier and get you better/faster service.
No idea if it really does anything at all... but since my phone is working just fine - and finally at HSPA and HSPA+ speeds(!!!) - I am not going to change it back anymore....
I have to say, the $45/month all-unlimited Straight Talk & Data SIM (AT&T service) really works well on my GT I-9300! It is not giving me LTE speeds, but it's just 35% of the price I used to pay Verizon before (month-to-month service w/ 450 talk minutes + 5 [upped to 10GB as part of their promo] Data plan) for LTE, which was sucking my REZOUND's battery dry in no time flat. And HSPA+ is certainly fast enough for what I need my phone for...
What's not to like??!
As for me, I like it much better now!!!
Glad you got it fixed quick.

Just for clarification though, I see you mentioned the I9300 using 1700 and 2100Mhz. Where'd you get that info? Those are Tmobile HSPA+ bands. I'd love for the phone to support that, but don't think that's correct

You may have a point there, buddy... Those are supposedly the bands that the International Galaxy S3 can pick up in general, according to Wikipedia. Here in the US, however, you're out of luck if picking T-mobile as your carrier for the I-9300, because they broadcast 3G on a different band, which the S3/I-9300 does not pick up by default... so I had verified by a bunch of folks in the Forums.
I was looking into exactly the same thing before I made the decision to go with a prepaid "Straight Talk" (AT&T) SIM card. ST also offers an T-mo version, but with that - as I had stated before - you'll only get 2G in the US; at least for now (note: this may change by end of the year/early in 2013, so I've read, as Tmo is making adjustments/improvements to their network and 3G/4G frequencies..).
Hope this helps.
If you happen to live in the US and haven't heard yet, all major carriers here will come out with the S3 in just a few weeks. Carrier-branded only, and "just" with the 2-core Snapdragon S4 CPU inside (due to LTE).
But, this phone is so awesome, I wouldn't even mind having only 2 cores if I were not able to run the International/Unlocked version on HSPA+ here in the US... But, 4 cores kick some serious butt, dude!!
Cheers,
Armin

That is wrong info..anyone can put info on wikipedia. It matters what's on the box and on the box it's the standard quad band for umts. There is no 1700 band on the box and so no hspa speed for tmobile.

Try leaving the Straight Talk Proxy setting blank. I think you will see much better data speeds.
I'm having the same problem, but your solution didn't work for me. I cant seem to shake edge connection. I had hspda last night

I agree kirdroid, you can't trust Wikipedia to be 100% truth. However, in this case the Wiki page is correct.
/wiki/Samsung_Galaxy_S_III
The page is for all models of the Galaxy SIII. There is a graphic on the right side with specs under it for ALL models. Then there is a table in the middle of the page that shows the specs for each model. If you look at the all models specs it looks like one hell of a phone. You have to look at the table with specs for each model to see that I9300 supports:
2G: 850, 900, 1800, 1900 MHz GSM / GPRS / EDGE
3G: 850, 900, 1900, 2100 MHz UMTS / HSPA+
T-Mobile H+ (2.75G) not working for me in Salt Lake City, UT. Customer support said 1900 MHz is supported for H+, but I'm guessing she didn't check for Utah. As of December 20, 2012 it is not available in Utah. You can search Google to see what markets it's available in: "t-mobile-closes-the-year-by-enhancing-coverage-in-14-new-metro-areas"
I'd post links, but I'm not allowed.
