Ok so i bought the vibrant, unlocked it, and inserted my att 3g sim. the issue is im only getting edge speed when my phone is 3g capable. any ideas to correct that? Like creating an apn of some sort?
Thanx!
im about 50 percent sure that at&t and t-mob use different frequencys or something for their 3g signals so they are not compatable, same thing happend with the nexus one and its 3g on at&t if my memory is correct

my only working theory is that the 1900mhz freq isnt as widespread as the 850mhz freq, as the vibrant uses 1900. (i think). so that may be it. but i ask only because some commenter on a diff forum mentioned the need to create a 3g apn.
ps. the captivate is too boxy for me. idk why att changed it
Those are at&&&-t frequencys tmob is 1700 and 2100 I think so if our antenna only picks up those iy wont ever work on at-t's network

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.

The Vibrant is capable of AT&T's 3G over the 1900mhz spectrum... if you live in a area where AT&T is only using the 850mhz spec... you will not get 3G.

HEY, don't listen to these guys. You can get both wcdma 1900 and wcdma 850 on the vibrant, don't worry, you will be able to get at&t 3G on your phone!
I'll show you how when I have time, maybe this weekend.

I also am only getting Edge signal on my unlocked vibrant. When I run a 1MB speed test at mobilespeedtest.com it says I am downloading at 2581 kbps which, according to their chart, is a little more than the average 4g speed. Very weird. I also can't download any apps but I am searching for a thread on that.

i'm confused, you said you are getting edge signal, but your speed test shows 2.581mbps? thats 3g speeds.
by the way, you can make the vibrant pick up both att 1900 and 850 signals.

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.
Derp.....

i'm not getting 3g either,
is there a link to a map to see if i have 1900 in my area?
what apn setting should be used, im pretty shocked that it did the edge APN settings on its own
Try dialing
*#2263#
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
I recently purchased an unlock galaxy s2 i9100. It is supposed to be GSM unlock with HSPA+ 21Mbps/HSUPA 5.76Mbps, EDGE/GPRS Class 12, Quad band GSM 850/900/1800/1900, Quad band UMTS 850/900/1900/2100 hardware capabilities. since I have gotten the phone i have not been able to connect to anything but edge. Tmobile assured me i had the correct APN setting. I would like to know if anyone know what I could to to enable the HSPA+ T mobile US uses UMTS 2100 to connect.

This is correct. However, it's only used for one way traffic (either uploading or downloading, i'm not sure which). UMTS 1700 is used for the other direction of traffic on T-Mobile. This means no 3G/4G without both frequencies.
Your 2 options:
1. Get a T-Mobile phone.
2. Switch to AT&T.

thanks for the quick and concise responses. I have a clarification: does this mean that I when Tmobile comes out with the variant my phone will be able to upgrade to Hspa via a rom or radio update or that if i want to keep this model i will have to wait to swap it out for the tmobile version

The I9100 will NEVER work on T-Mobile. The SGS2 that they are releasing has different HARDWARE. There will never be a way to make the phone you have now work on T-Mobile 3G.
As others have said you'll need a different phone in order to get it to work on T-Mobile USA's 3G/4G frequencies.
You'd need a penta-band phone in order for it to work on all of them. I think Intel is curently working on that or already did but that's all there is. You'd need both 1700/2100mhz in order to use it with 3G.
I don't get how people don't research before they buy!!

Hi, I have the white s2 i9100unlock version and when I put in my

The international i9100 does not support 4G. Only option would be to get a 4G enabled one.
its because the international galaxy s2 doesn't have the same 3g bands as T-Mobile (assuming you are T-Mobile USA). They run off of 1700/2100 while the phone itself supports 850/900/1900/2100. While only the 2100 band matches, if you don't get 2100 coverage in your area, you will default to 2g.

So you started another thread on this, where I also answered your question. This phone will never get HSPA+ speeds on T-Mobile USA - or what they call "4G". It lacks one of the necessary frequencies for it. It will only get Edge speeds. From what I remember on how T-Mobile USA's network functions, 3G and "4G" need both 1700 and 2100 mhz to function, as it uses one frequency for download and the other for upload.
EDIT: Here's the wikipedia article on AWS, which is the band T-Mobile uses for 3G/4G. In brief, AWS uses 1700 Mhz for uplink, and 2100 Mhz for downlink. So since it only gets half of the band, it won't do "4G".

Unfortunately, the bolded/underlined part is simply not true. T-Mobile USA needs your phone to be able to get both 1700 mhz and 2100 mhz UMTS frequencies to do 3G/4G. If your phone doesn't have one of the frequencies, it won't do 3G/4G at all, and fall to Edge (2.5G).
What if I overall another ROM? Will it help?

No. The phone simply doesn't have the hardware to receive the frequency. Nothing you can do to fix this.

You need Galaxy2 HD LTE to access 4G. That particular model is not available outside Korea at the moment. If you want 4G, try Samsung Galaxy Note or LG Optimus LTE - also known as Nitro HD, or HTC phones.

That indeed is weird and inconvenient, but I guess telco's can setup their system however they like... It may have lot to do with number of people using mobile services. In OZ we have 22 million potential mobile users using 4 major telco companies, whereas in USA, they would get most of OZ population just in New York city, let alone rest of the country.
Ah systemcrasher I think they might be load balancing the hspa+ mimo across the two freqs. Telstra nextg doesn't need to coz there's allot less people here.
If that's the case still should be allowed to fall back to a non mimo mode.
Let this be a lesson to the OP, always research all carrier pre requisites before buying, also consider other carriers encased you'd like to stay open to other options.

So the answer is the link to the wikipedia article in my quote above. It's not T-Mobile USA's doing per se - they just purchased the AWS-1 (also known as UMTS band IV) band of the spectrum. That's just the way this band is set up. Wind and Rogers in Canada also use this band.
I was thinking about buying the International unlocked Galaxy SIII GT I9300 and saw how it would be cheaper in the long run, but my main motivation was being able to move from carrier to carrier if I wanted to and not having a contract. I seem to be reading though that the international version is only compatible with AT&T and T-mobile at 3G and is not capable of 4G speeds at all. Also, that even American versions are not always compatible with eachother. So am I correct in thinking that if I get an international version I'll be stuck between T-Mobile and Sprint at 3Gs. And that nothing can be done to the phone to allow an International phone to work with Sprint or even an American Sprint to work on a T-Mobile network? I'm starting to think it might be easier to just get an American phone and jailbreak it.
The international one will never work with sprint or Verizon, the AT&T and t-mobile versions will never work with sprint or Verizon.
The difference is hardware, Verizon and sprint are cdma, the rest are gsm.
The international one will work with AT&T with 3g and 4g(actually its hspa+ which is technically 3.5g) and will work on T-Mobile only in 2g for now, in a few months it will work on 3g and 4g when they refarm their 1900 or 1700mhz (can't remember which) band to 3g.
No matter what you do to either the international or US gsm versions they will NEVER EVER WORK ON SPRINT OR VERIZON.

I see, that's what I was afraid of. The AT&T and T-Mobile option still seem attractive, but in your opinion will the Verizon/Sprint with a jailbreak route be better in the long term since the LTE is by far the superior option(from what I've read)? I've seen AT&T has LTE but the International version wouldn't be able to work on a LTE network anyway, would it??? I plan to download most things on my laptop and move them to the phone anyway, the only important thing to me internet speed would affect and my main concern would be live video chat, would the 3G or HSPA+ be sufficient for that? Other than talk and text the phone will be mainly used for games, movies, music and the superior GPU in the International version I think would be better for that? Are there any other phones comparative to the Galaxy III you know of that might have both the CDMA and the GSM, the "world phones" as I've seen them called?

You can't/don't jailbreak Android phones. Hard to even know what you are talking bout trying to accomplish? It's very simple.
1. Buy a phone from a carrier and use it on that carrier. That's the easiest option.
2. Buy an International GS3 and use it on AT&T 3G or 2G.
3. Buy an International GS3 and use it on T-Mobile 2G.
If you try any other options you are just going to confuse yourself.
Definitely don't get the sprint or Verizon ones, you are stuck on cdma then. The at&t one has LTE and the T-Mobile one has dc hspa+ (theoretically up to 42mbps) the international one has standard hspa+ (up to 21mbps) and I regularly get between 5-8mbps down and 2-3mbps up and I live in the country.
The gpu and cpu on the international one are better too.

I have a bad habit of using the words root and jailbreak interchangeably, I meant root the phone. I guess I have to decide how important LTE is to me. It'll either be AT&T or the International version. The superior GPU and CPU are attractive, but so are the LTE speeds. But I guess with the limited data maybe not. But thanks for your help, this clarified a lot for me.
Frequency Concern
I have the exact same problem!
I am planning to buy a Galaxy Nexus, which works for UMTS (850/900/1700/1900/2100MHz) and GSM (850/900/1800/1900MHz). I read from wikipedia that the 3G and 4G networks from Tmobile are carried on the frequency of both 1700MHz and 2100 MHz. Does that mean Galaxy Nexus can use 3G and 4G on Tmobile network?

Oh really?! Then I should sell my international version of Galaxy S II for a Galaxy Nexus. S II doesnt receive 1700MHz. I read from Wikipeida: This band (Tmobile 3G and 4G) was an area of wireless spectrum, half in the 1700 MHz (1.7 GHz) and half in the 2100 MHz (2.1 GHz) frequencies. SO I was thinking: Hey, how about getting a phone with both 1700 and 2100MHz to work on Tmobile 3G and 4G.
So you can actually use 3G? or even 4G on Tmobile? Is it so slow or weak that makes you want to change carrier?

I have a Samsung GT-I9300 unlocked Gsm phone. I have started AT&T GO $60 data plan. I have tried for a week now to get data with no luck. I can talk & text fine, and it works great off of WI-FI. AT&T has tried everything they can do and says it is a problem with my phone. I was previously on Straight Talk but was stuck with EDGE speeds and not good coverage. Any help would be greatly appreciated.
I have been reading and searching online to find the definitive answer to this question. I am currently using a straight talk compatible sim in my verizon galaxy s4 and it works great - of course straight talk does not use LTE so I am limited to 3g speeds. I'm also trying to find out if it is possible to use a tmobile sim in the verizon galaxy s4 and get 3g speeds? How about LTE? The appropriate radios seem to be installed but I am not sure if that is enough. Has anyone done any testing on this front?
Thanks!
If you go into your hidden menus and dig around enough you will find options to enable the WCDMA and GSM radios. Back when I tanked my sim card I was digging through the menus for hours and at one point under network options I could see AT&T and T-Mobile signal even though I didn't have the SIM to actually connect.
I would imagine if I had the sim I could have connected no problem.
But because the menus are so deep and obnoxiously laid out, I don't have more specifics on where all to navigate to find the right options.

You didn't get any signal because nothing was turned on in your hidden menus to allow it.
And yes, loads of frequencies listed for LTE, WCDMA, and GSM.
You have to enable hidden menu. Then start digging. Like I said there are too many options/submenus for me to remember exactly where everything was.
If someone really wants to get their phone on another network it is possible. They just have to really want it and therefore really put in the time to dig.

The latest update from 4.2.2 to 4.3 has an update in it to enable band 4 aws that vzw will be using. Once you've updated to 4.3, it's just a matter of waiting for vzw to turn on band 4 in your area.

However if you have a VZW Galaxy S4 on another network, the option of OTA 4.3 update I don't think is possible.

I have updated my phone to android 4.3 and discontinued the contract with Verizon. Now I cannot access any updates from Verizon.
Do you still feel, when vzw turns on band 4 in my area, I can access 4G on my GS4 with Straight Talk sim(4G enabled)?

I have been reading and searching online to find the definitive answer to this question. I am currently using a straight talk compatible sim in my verizon galaxy s4 and it works great - of course straight talk does not use LTE so I am limited to 3g speeds. I'm also trying to find out if it is possible to use a tmobile sim in the verizon galaxy s4 and get 3g speeds? How about LTE? The appropriate radios seem to be installed but I am not sure if that is enough. Has anyone done any testing on this front?
Thanks!

I can absolutely 100% confirm for you that a Verizon Galaxy S4 on the latest Verizon radio can access T-Mobile LTE. This post and its attached screenshots were done from T-Mobile LTE on a VZ GS4.

I'm in the process of switching to T-Mobile from Verizon. Could you do me a favor and tell me how you got your Verizon S4 to work on T-Mobile? I thought I needed a new phone altogether. According to your screenshots, I may not...
Anyone able to get LTE on a ATT network?

It's really not that hard. You just need to be able to add the APN for T-Mobile. The VZ phone is already unlocked. I also just flashed one of mine back to the MDK baseband (radio/modem) and it also supports T-Mobile LTE where I am. Coincidentally, it gets 2 bars + LTE in this particular location in LA whereas the T-Mobile GS4 with Tmob radio is getting 1 bar + LTE.

Sorry, I'm afraid that one's not going to (easily) happen. The phone may or may not have the hardware for it, but you'd need the right radio to enable the LTE band that AT&T uses. Right now, I don't know of one, and I don't feel like playing with the AT&T radios to see if they would happen to flash properly to enable things. T-Mobile & AT&T use relatively identical phones and can run LTE on each other's respective networks. So, I'd say, use one of their hardware sets on AT&T. I use AT&T LTE on a Nexus 5 and a T-Mobile GS4, but I can only get H+ on the VZ GS4 on AT&T. The VZ phone does do the T-Mobile LTE band just fine, though.

I was able to get LTE with AIO Wireless sim by toggling to LTE/GSM Auto(PRL). It seems to pickup Band 4 for ATT.
My 2 cents.
Does this still work?
I have a heightened interest in switching to T-Mobile now that they will pay for my early termination fee. I have a rooted VZW S4, added a new apn, and I am using an older sim card but i can't get it to connect to t-mobiles network. What all needs to be done to my phone in order for it to work. I did some research and saw that tmobile and verizon have the same LTE frequency and band.
EDIT (1/10/2014: I bought an activation kit at Walmart and activated the sim card. I am not connected.
I'm also using a Verizon Galaxy S4 with Straight Talk (ATT SIM). I have voice and text, but no data. I've changed the APN with no luck. I tried it in my Verizon Galaxy S3 and received E (Edge data) which was CRAZY slow. Any suggestions? I have a ATT Galaxy S4 Active being delivered today, so I guess it doesn't really matter, but very curious why I can't get any data on my Verizon S4 through Straight Talk.
If this helps anyone
This is how I have LTE with T-Mobile working on a Verizon S4...
I am getting 4Glte on my vzw S4 using tmobile prepaid!
When I got tmobile I was only getting H+ and 3g and all of a sudden I start getting 4Glte! I love it!
