Galaxy SIII Factory Unlocked no 4G - Galaxy S III Q&A, Help & Troubleshooting

Hello as the title says its been 2 months and since I connect my at&t phone with metropcs I haven't received any 4g at all just one time but it despaired 5 seconds after.. I already called metropcs like 3 times and they did a refresh or what ever they call it . they told me to change the APN I did that no results.. I been throe all my city and no 4G and its stressfull because EDGE its really slow :/ my wife's exhibit is just in my pocket and it receiving 4g and mine EDGE.. I already went to metropcs and they told me that because is a BYOD they cannot do anything about it because their towers signals I think they are different that my phone have but.. do you guys have any suggestions that I can do too have 4G signal ?? please help

bump..

You're in the wrong section so best to try the GS2 section / AT&T variant, so I don't think anyone can really help you. Are you sure your phone is 4g compatible?

yeah because galaxy s3 its 4G

No, not all S3's are 4G. What is your exact model number?

exact model is at&t SGH-i747

I no little of your American networks but after a small amount of research I have found out that metropcs uses the t-mobile network that operates on 1900 MHz GSM and 1700 MHz UMTS.
Searching your phone it only matches the 1900GSM but not the 1700UMTS that t-mobile uses.
Is your wife's the exact same model? If not what is it?
Further to that you need to report this to a mod and have it moved to the at&t forums, this one is for the international version.

[Q] Korean version GII 250S for AT&T

Hi guys.
I didn't know where to post and I have few questions on my Galaxy SII I bought from Korea and brought to USA.
I have KT's 250S galaxy SII and I'm trying to use it for At&t. I tried to put my At&t sim card in and looks like it is getting some connection. I was able to make a call.
However, looks like it's not getting any 3G connections. I heard there is some modification on the network I need to change to get 3G. Could you please let me know what should I do?
Thank you,
Andy

Go to the miui thread in development section and use the apn from there. That should theoretically fix your issue...

From the third post down:
Code:
<< Korea Galaxy S2 Network support >>
Double band UMTS 900/2100
Triple band GSM 900/1800/1900
<< EU Galaxy S2 band Network support>>
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
AT&T and International (I9100) GSIIs support the same bands, which is why I9100s work perfectly in the US. Your device is completely missing support for the 850 MHz band (first device I've seen in years that wasn't quadband GSM other than dumbphones) and also missing support for 3G in the 1800 MHz band.
So you will not have 3G coverage anywhere, and you will completely lose coverage where AT&T uses the 850 MHz band.

Having extreme trouble deciding between galaxy s2 and htc 1s please help!

I just dont know which one. Its for my girl. These will be tmobile phones in this decision which will be on simple mobile.
Right now i have the lg g2x which is unlocked/rooted/running hellfire 2.2 Rom GB 2.3.3 and i love it, battery life sucks though.
What do you guys think about htc 1s vs galaxy s2? Or should we get galaxy s3?

Since you're asking for a comparison to the HTC One S, seems you're asking about phones for T-mobile USA?
This particular model of Galaxy S2 is not the model for T-mobile USA, and will only get Edge mobile data speeds on that network.
I'm guessing you want to know about the SGH-T989 .

As I said, the T-mobile USA Galaxy S2 is a different model. I linked the forum for that model above.
See wikipedia.
The i9100 (which this is the forum for: look at the top of the page) doesn't have the required antenna hardware to receive 1700 mhz UTMS, which is a required band for AWS. (the other frequency bring 2100mhz) T-mobile USA uses AWS for high speed mobile data.
So, the i9100 will only get Edge on T-mobile USA's network.
But if you don't believe me, just type "i9100 t-mobile edge" into google.

Ok i get what you are saying now. You scared me for a second there. I thought you meant "this model" as in the one i was referring to. Ok well while we are on the subject, isnt there something that can be done to the phones to switch the antennas like installing a new radio or something, or is it an actual physical piece of hardware that runs off different mhz to get 2g/3g/or 4g?

It's hardware. There is nothing you or anyone can do to the i9100 to get high speed on the T-mobile USA network with that phone.
If you want a Galaxy S2 model that gets high speed on T-mobile USA's network, you want the SGH-T989. I linked the forum for it above.
And back to your original question......
Get one S
Or S3..
do make sure one S is the Qualcomm S4 not the S3 with 1.7 GHz model.
HTC making one S with older processor after S4 shortage.

ATT Galaxy S II - i9100 T-Mobile 3G/4G Network???

Hey whats up erybody?
Im new to the forum as well as the android flashing/modding scene as i've always had an iPhone but recently gave in to this Galaxy sII as it looks and performs amazing. The only issue I have currently is I own an ATT Galaxy sII that is unlocked and I am using for T-Mobile but cannot get any 3G/4G network at all.
This phone is rooted and running cyanogen mod on ICS 4.0.4. I have read online about people flashing there ATT Note's radio to force your phone to accept 3G/4G for T-Mobile and I was just wondering if this is possible for the Galaxy SII? I tried using the same method but no luck, can anyone possibly point me to the right modem to install if one is available? This phone is great but I cant stand this slow ass EDGE signal.
Thanks :cyclops:

First off, you're in the wrong forum for your device.
This is the forum for the i9100, the international Galaxy S2.
You say you have the AT&T Galaxy S2... Which is the SGH-I777.
Second, since ATT and T-mobile use different frequencies for high speed mobile data, most devices for ATT will only get Edge on T-mobile. Vice versa, most devices for T-mobile, if unlocked for ATT, will only get Edge on ATT's network. SOME devices you can flash a different modem, because they have the requisite antenna hardware to get the necessary frequencies.
Unfortunately for you, the SGH-I777 isn't one of them.
Unless, you actually have the Skyrocket, which is the SGH-I727. (check the label under the battery to get the exact model number) That phone, you CAN flash a T-mobile modem to it and get high speed on T-mobile's network.
Ahhh I see. When I power on the phone it displays the international model however in the menu settings it does say SGH-I777 which is why I was a little confused since there are so many differen't models aparently.
Looks like im screwd until later this year when/if T-Mobile does go good on there word that they will be acquiring new towers to promote the other frequencies for ATT devices. Thanks for the reply.

The boot screen and indeed, the about phone screen can change depending on what is flashed to the phone. So if you flash an i9100 firmware to an i777, it will then display the wrong model when booting. Which is why I said to check the label under the battery to be sure.

CTOMGEE,
I have the i9100 International Galaxy S2 and am wondering if I can access 3G speeds on T-Mobile? I know the phone is not 4G compatible, so unfortunately I won't be able to access those speeds, but I am wondering if I will be forced to use the EDGE network.

Not as of now. T-Mobile in the US uses AWS currently for 3g and "4g". This band requires both 1700 & 2100 mhz for data to get these speeds. The phone doesn't get 1700, do it won't get higher than Edge.
There are rumors T-Mobile will be re-purposing 1900 mhz (which the phone DOES get) for data, so if and when that happens, the phone will probably get high speed mobile data. But until then, you're out of luck for T-Mobile with this phone, and will have to use ATT to get high speed data.

Hi ctomgee and others, I'm using a Galaxy S2 GT-I9100 that was bought unlocked. I'm also getting only 2G speeds on T-mobile. Could you tell me what is flashing the T-mobile modem and how it is done? Can I try to do this so that I can get 3G speeds? If this is not possible, would I get 3G speeds if I buy a S2 from T-mobile?
On the sidelines: What do they do to the phone that the phones bought from T-mobile would work but the others won't? Is it something done to the hardware or the software? If the change is in the software, can't we try to do it ourselves - are there any online tutorials on this?

Flashing a modem is essentially changing the software drivers for your antenna. This does not, however, change what frequencies your phone is capable of receiving. This is a hardware limitation.
The T-mobile USA Galaxy S2 is model number SGH-T989 - a totally different model than the GT-I9100. The hardware is completely different. The size itself, the CPU/GPU/SoC, the antenna hardware - all different. This isn't something you can fix with flashing a modem.
If you are patient, as I stated above, T-mobile USA is in the process of re-purposing a frequency the I9100 DOES get so it will get 3/4g on T-mobile. When that happens in the market you are in is up to T-mobile.

I spent hours online chatting with support trying to get this information and they couldn't provide it. 10 minutes of internet searching and you said EXACTLY what I needed to know. Thank you sir!! Helped me a ton.
Also, just a heads up. At the end of this year (2012) T-Mobile is going to launch their 1900 mhz band towers (see: newsroom.t-mobile(d0t)com/articles/4GNetworkEvolutionVendorsSelected) so AT&T phones that use that 4G band will work with T-Mobile once unlocked and moved over.
Thanks again!

You can set the network mode to WCDMA only... but I think there's a problem with that. If you wander into an area where T-mobile doesn't have "4G" coverage on 1900mhz, then I don't think you'll have any signal at all. When it is set to GSM/WCDMA (Auto mode), it switches automatically to Edge if you don't get the "4G" signal.
Wrong forum, this is for the international i9100 not Skyrocket.

The OP is from July. The guy above me today was asking a general question, and ATT sells TWO variants of the GS2 - the SGH-I777, which is their branded regular Galaxy SII, and the SGH-I727, which is the "Skyrocket" - which is the variant that has LTE.

Can You Modify Your Rogers Galaxy S2 LTE to work on aws 1700/2100?

Hello Everyone
I don't know if this has been asked before, but I searched and found no answers. Basically, Me and my dad want to switch from Rogers to Mobilicity (which uses the 1700/2100 frequency), so we went to the mobilicity store and tried my dad's galaxy s2 lte (rogers version) with the mobilicity sim card, and the phone didn't detect mobilicity's network (it goes into Rogers roaming mode i think). So I started looking around, and I found this advertisement on Kijiji Calgary about modifying the S2 LTE to work with Mobilicity's frequency. So, Is there a way I can convert/modify the phone by myself to work with the AWS 1700/2100 frequency? I assume the phone has to be rooted first if such thing is possible?
Thanks!
I don't think so as it's HW related.

i have the tmobile version (SGH-T989) flashed to the Rogers radio... and now i'm able to connect to RoBelLus
and when i'm fed up w/ their high prices, I can just flash back a Tmobile radio and go with Wind/Mobilicity
it works for the ATT Skyrocket & Tmobile version of the S2 ... i'm not sure if it will work with the Rogers one... do some research, you should be able to do it
PM me if you some help researching... if i can't get u the answers, i might be able to guide you to the right threads

Question about International Phone compatibility

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.
Sent from my GT-I9300 using xda premium
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?

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.

Help, I have an I9300 and I can't configure it to recieve data I am on the AT&T GO $60 data plan and AT&T says it is my phones problem. I've tried a lot of different settings and it still shows up as disconnected under the mobile network state. Any help would be greatly appreciated.

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.

Help, I have an I9300 and I have tried for a week to get AT&T GO set up for data. I can talk and text fine, but no luck with data AT&T says it is my phone. Under mobile network state it says disconnected. any help would be greatly appreciated. It is an unlocked international GSM phone.
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.
