I travel both in the US and International a lot. I am seriously considering switching to Skyrocket II when I travel to LTE markets. So assuming I can unlock the SkyRocket, it should work internationally by popping in a SIM card. I cannot seem to find the thread, is there something that AT&T does that not make the SkyRocket very well in terms of the speed?
The countries I visit probably will not have LTE for a while, so 3G is probably be the best I can hope for, so will that be an issue? Can I turn of the LTE for example?
I have been using the Atrix successfully, the only issue I have international (with a different SIM card) is that occassionally the carriers have "data" roaming agreements in some cities, for 3G e.g., and I could not get the Atrix to switch to 3G data roaming at all, it would always stick to the primary carrier. I don't know whether I have explained this correctly? Yes, I had to setup the APN's manually, created my own CWM zip which I would flash, hoping Skyrocket will have CWM and since it is already rooted.
LTE band support is pretty fragmented, so the LTE radio likely won't work well if at all on international LTE systems.
Also, if you like custom ROMs and such - the I777 has lots of commonality with the I9100. The I727 (Skyrocket) only has commonality with the T-Mobile T989. By the way - while the I777 had kernel source 1-2 weeks before device release, the Skyrocket has no kernel source available and the T989 sources don't produce a usable kernel on even the device they were intended for.

Entropy,
In your opinion if you live an a current LTE market and could either keep the i777, or get the i727, is it worth switching?
I understand that from a development standpoint the i727 is more of a challenge but if I am looking for a phone that I can get LTE on that operates in a similar manner to the GS2, why would the Skyrocket not be a better option?
Thanks!
Lets not forget the DSP of Qualcomm SoCs are much worse. If you like playing HD content on your Int. SGS2 don't trade it in for a skyrocket.
Here are results of a Sensation, which shares the same DSP:

Digital Signal Processor aka Video playback capabilities.
The Exynos is the best on the planet currently- I have 1300 HD movies and it can play the largest ones.
Meanwhile Qualcomm SoCs can only play a few files. The SGS1 is honestly better.

Yep.
Actually, media playback is usually in the GPU on nearly all modern processors... So it's the GPU that sucks.
So the GPU on the SR is inferior to Gs2?
Entropy any thoughts on what I mentioned, about being in an LTE area?
I don't think we have a way to unlock the phone to use in different carriers yet. All free unlock apps didn't work.

If you really need LTE, then the Skyrocket is the clear choice, however if that isn't as important to you, you might try to get your hands on an I777. Its very very similar to the international version but with ATT 3G bands, so you'll get the enhanced development potential with the benefit of high speed data in the US. It is also believed that the I777 has an NFC chip, but we haven't figured out how to enable it as of yet.

Wrong. We've got NFC working, however only to read tags, we can't do card emulation (Google Wallet) yet from the looks of things.
The international version actually fully supports the AT&T 3G bands, a rare thing for an international device.
The main differences between the I9100 and I777:
FM Radio removed
NFC added
Touchkeys moved from the "International" layout to the more typical for the US "four keys" (menu, home, back, search) layout.
This is why at this point, one can automatically take many I9100 ROMs (likely any XXKI3-based one) and get full functionality except:
1) Home button haptic (requires a ROM-specific mod)
2) NFC (requires a Settings.apk tweak)

Thanks. Yes, I actually want the ability to turn it off i.e LTE. I believe or heard the rumors that the SR stock rom has this disabled. Not sure if it is true or not. Whereas in the i9100 it is available as an option and probably i777 too.

On Samsung's website, the specs say that the new Galaxy S II supports 2g/3g/HSPA+ AT&T bands, as reported by Engadget and phonedog as well. However, I've heard from different sources that Samsung has locked down American GSM bands to avoid those across the pond buying international phones rather than the always slow to release cell-provider branded phones (like the Fascinate or Captivate)
My question is are the American GSM bands locked on the new Galaxy S II or can I use the phone with AT&T? I desperately need a new phone, given the fact that my Aria holds less than 6 hours worth of charge without having 3g or wifi on. I'd rather not wait and go ahead and pre-order this phone if I can.

This has been a hot topic of conversation over the last month or so but finally we have confirmation of the Samsung Galaxy S II specs that remained to be clarified.
Having spoken to the UK Product Manager for the Samsung Galaxy S II, we can confirm that UK stock will ship with the following:
1. Samsung Dual Core Exynos CPU (not NVidia Tegra 2)
2. 3G frequencies are 850/900/1900/2100 (Quad band)
3. Display is Super AMOLED Plus
4. Box contents: Handset, battery, charger, USB cable, headset, Quick start guide.
If you have an outstanding pre-order with Clove for the SGS2, you will be receiving an email regarding this confirmation of spec within the next day or so and you will be given the chance to cancel the order if this is not the specification that you were hoping for. However, we hope that for the majority of you this will be good news and we look forward to shipping your order as soon as possible.

No sir, it won't work with T-Mobile except on Edge (2G). T-Mobile's 3G/"4G" uses the first half of the 1700 band. The i9100 doesn't support 1700 in the 3G freq.
Sorry! The G2X looks like a suitable alternative if you need a T-Mobile USA alternative to the GSII.

I have a real hard time believing this. Bands are hardware supported/unsupported. Sure, they can lock it via software somehow, but that'll easily be disbanded once custom ROMs come out.
Plus, my biggest grief with this "locked bands" claim is the fact that it'll make your phone completely useless with international travel. For instance, why would Samsung sell "unlocked versions" if the phone was unusable in the US? Doesn't make any sense to me, and probably means all these claims are false.
As I have already stated elsewhere expansys when asked on the phone said that the versions they had were dual band with euro freqs as sold. They had not been able to enable the 850/1900 in the menus. Many people here should be familiar with the tmo debacle with the G2X which was of course marketed on their own site as having the Quad band 3G but after launch saying it only support 850/1900 in hardware. This may or may not be true and they could be there and simply need enabling or to have the radios installed with a new radio update. At this time there is no AT&T 3G on that phone which is the bottom line for now.
When someone actually connects to AT&T 3G, that is when it is confirmed working, not before. I have yet to find such confirmation anywhere.
yeah i have to agree, i dont care what their website says, i'd bet a whole lot of money on the fact that this phone would not pick up ATT 3g bands right now if someone were to try their SIM in an SGS2.
that said, i dont think anyone has tried this yet. if it DID work, i'd pick one up tomorrow.

Let's clarify: The G2X debacle was due to an error on T-Mobile's behalf, with an official clarification from them as such:
"The T-Mobile G2x fact sheet, attached [PDF link], contains accurate information. The T-Mobile website is incorrect and we're working to correct it. The G2x supports 850/900/1800/1900 MHz for 2G/GPRS only, and supports 3G/4G UMTS/HSPA+ bands I and IV. The G2x does not support AT&T's 3G bands. This banding is hardware based."
http://www.engadget.com/2011/04/27/t-mobile-g2x-lacks-quadband-hspa-shatters-dreams/
(And, let's keep in mind T-Mobile doesn't actually design/manufacture phones. On purpose or not, this was a screw-up on T-Mobile's website.)
Samsung's site clearly says that the Galaxy S2's hardware supports quad band UMTS. Even if it is carrier locked or something, the unlocked versions should not have this problem.
For sure, no problem waiting if you're choosing to play it safe. But, I still personally think this is a bunch of nonsense propagated by a few folks. Even the T-Mobile announcement above clarifies that the problem the inaccurate info caused was not from a software lock but by a lack of hardware support.
Guys, all this jiberish of unkocked/locked bands blah blah blah.
It has quadband it will work worldwide and AT&T and Verizon will have it by 3rd/11.
Cant say about T-Mobile. But they are bought by AT&T so eventually yes as it will be one big AT&T network anyway.

With all due respect, I can say just about anything I damn want short of the mod telling me otherwise. Are you a moderator?
Your claims in that thread are not even accurate. You continue to say that bands are selectable. I understand this, and never argued this point. Please stop for a minute and understanding what I as well as several other people are very happy about: All phones come with defaulted bands enabled or disabled... those I9100 users are showing that out of the box in automatic band selection mode, all 4 UMTS bands are ENABLED. Big difference and has nothing to do with the fact that you can go in and personally enabled whatever band you want.
I just want to know how different the development will be for the international version compared to either the Canadian/US version (which presumably will be the same with S4 & 2GB RAM). People are posting that Samsung will give the international version updates earlier but is it that much sooner than other variants (or do the NA variants not get updates at all)?
I'm not sure which to order since I'm from the US (I have no use for LTE but price and ease of warranty are factors).
This is my problem too, which to get?. I'd love to have more development options, but at the same time I want faster speeds.
At a glance it appears that the internation one is going to be HSPA+ 21Mbit/s connections. But the LTE North American models will have LTE support and if LTE isn't avalible in your area then it defaults down to DC-HSPA 42Mbit/s not to mention the 2GBs of ram.
This is a hard choice :/
Both will have great development. Look at the intl note and the north america note for example

I also don't know which version to choose... Less pricy 2gb dual core with LTE or international with more support quadcore better GPU but less ram and no LTE...
I wanna know which one is better for multitasking, also if the battery life is better on the dual core or not and if 2gb vs 1gb really matters...
Id choose the usa version but i just hate that awful carrier logo on the front of the phone, it ruins all the beauty!

Thankfully my carrier doesn't brand there model number on the phone itself. I think they do this because they sell there phones in an unbranded/unlock versions to other non-major tel companys in Canada (don't know if this holds true for the SGS3 when it comes out though)
I've made my decision I want more ram and faster connection speeds through LTE and DC-HSPA. So now I'm just waiting for the thing to release lol. Also waiting to hear back from them if i can get it cheaper as an upgrade, otherwise their full price will be $599

Don't mean to drag this back up, but I was going to create a new post until I found this one.
I am in the same predicament. I'm wondering if I should get the Intl or US model.
I'm on T-Mobile, and they will be refarming their PCS band for HSPA+. I wonder if it's a safe bet to get the Intl model and rely only on a single 1900 MHz band for data, or go with the carrier's model and enjoy the potential of 2 HSPA+ bands (1700/1900)...
Plus, there's the development support issue as well. I've enjoyed my Intl SGS2 when I was on AT&T because of all the developer support - love the mods and the ROMs. Then I moved to a GNex when I went to TMobile.
My ideal ROM situation: CM9 ROM, stock Android Experience ROM, and modified Samsung ROM (themed to look/feel like ICS so I can keep the camera app while enjoying the stability and the highly optimized framework). I love using Titanium Backup and ROM Manager to basically change ROMs without loosing much data whenever I'm in a different mood.
I'd like to eventually have 1 SGS3, 1 iPhone (the next model, esp when TMobile's PCS band gets refarmed), and I'll keep my GNex for shiz and giggles.
Just not sure which to get - both seem to have their pros and cons.
Do these two phones have identical hardware but different firmware, so that flashing for example the CM9 mod would make them identical, or do their hardware differs from each other, considering different band support and lack of LTE on T-Mobile?
Thank you.
For the most part hardware seems yo be same... you may have to switch the modems though. Expect a common Cm9 base and then a zip flash for each service provider.

Hopefully there will be some good collaboration between the ATT/Tmo (and possibly some parts from Sprint/Verizon) devs since the hardware is so similar.
It opens up the possibilities for a lot more ROMs!
Actually my question was more about the possibility to use the devices across the networks using custom mods (e.g. to use the I747 on the T-Mobile network).

You can do this without mods but you won't have access to the 3g band on TMo just like TMo won't have access to the LTE 4g ATT Band...flashing a diff modem/radio won't give you the missing bands unless the hardware actually supports them and its just locked out...which currently isnt known.

It's a very valid question… the AT&T Galaxy S III is $550 out of contract; the T-Mobile version, $630.
If you're paying out of pocket, $80 less for what amounts to the same device (arguably, the AT&T one is better since it has an LTE radio) is nothing to sneeze at.
I am having the same question as well.
The situation here is the same to what I have as Rogers/Bell/Telus vs Wind/Mobilicity
I'd like the flexibility to use the phone across the network since the new carriers charge way cheaper than the big 3....
I suppose the hardware between the two model are identical. All support the same band 850 900 1700 2100 (AWS/LTE). Only the AWS version has the LTE radio disabled and HSPA 42 enabled???
It should work, the phone is locked to att thou. You will have to have it unlocked. But the skyrocket and the hercules were interchangeable between networks. But the international will not work on lte or Hspa.

So you are saying that that radio modules of these two phones are identical. Meaning that T989 supports LTE, and I747 supports the 1700 band (they just have to be unlocked).
I'm gettin mine unlocked and using it on straight talk t mobile. I need to get that hspa 42 workin. It's just software. From what I gather, once t mobile rolls out their LTE they may just release a firmware update enabling LTE on the t mobile galaxy sIII's. This phone is a seven band monster world phone. To such an extent that carriers are turning features off.

All the radio modules on this phone are integrated in the S4 processor. And the processor is identical. One would have to conclude, that yes, that is the case.
From a strictly electrical background the modem is software running on transistors which can handle being pushed to the frequencies T-mobile requires, so I would think that it would be doable with the right software. When a transistor has the ability to handle the current and frequency the rest would be a matter of software, I assume.
As for LTE I have no knowledge as to the hardware or if there its something missing in non LTEs.

It is interesting as its normally a possibility with Galaxy devices. This is a bit different since they have used slightly different models. We won't know until we get flashable radios and someone is brave enough to try to flash it on their device. I know with the Skyrocket I was able to flash a T-Mobile radio and get a 3G signal on wind (same type of network but in canada). The only limit was that you couldn't take a t-mobile version, flash at&t's radio and get LTE.

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.

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!

Looks like i occasionally get the 4G speeds on tmobile on my i9100, but it switches between Edge and 4G quite frequently. Anyone know how to force a 4G?

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.

Guy posted in i9100 forums because he tripped the flash counter causing his phone to say i9100 so he was confused and posted there. Asked about TMO only getting 2g and was already answered,

Same problem , get mostly Edge and Very less 4G with my International 9100 in T Mobile. Was wondering if a modem change will fix the problem . I am currently on Slimbean Rom. Any suggestions guys ?

Agreed since we are missing 1700mhz here but I was wondering whether its possible to capitalize on the 1900 mhz freq.

hello every one I was wondering I have the i9100 and I have metropcs on it and I also flashed omni rom on it but I was thinking that I need to flash the us radios on it because I got it from Japan and as I can make calles they drop alot and the network is so slow so is this something where I would need to flash that ? and if so can someone post a link for the file's?
So... Galaxy SIII in Europe comes with quad core processor - or so I've read... Why does the US only get dual core?? Can I use a European SIII on US T-Mobile network if I can get one?

The US version has qualcomm chip which supports LTE, the Exynos does not... INTL version has 1GB RAM, and qualcomm has 2GB RAM, yes you can use an unlocked INTL I9300 on T-Mobile but will not get LTE and have less RAM... The trade-offs are up to you...

Because the Exynos processor doesn't work with T-Mobile's non-standard 42Mbps on AWS (1700 MHz) and it also doesn't work with the LTE. You can use the international one on T-Mobile but you'll only get EDGE data. If you use it on AT&T though you'll get up to HSPA+ because most of Europe uses the same bands as AT&T (850/1900 MHz). If you want to use international phones, T-Mobile is the worst carrier to be on in terms of data speeds, but they're moving to the same frequency as AT&T, so eventually you'll be able to use it on T-Mobile with up to 21 Mbps.

To be fair, the i9300 is a lot faster than the US models. But to be honest, unless you game, you won't notice a different. The 2GB of RAM was a "whoops, my bad" from Samsung for having to switch processors; RAM does not affect performance unless you have too little RAM. Even the Nexus 7 comes with 1GB of RAM. But anyways, it depends how you use your phone. The other big thing is that the US models have the "bug" or "feature" where you might lose your IMEI when flashing anything to the phone, with no chance (so far) to get it back, meaning you'd have to do a warranty swap to get a working phone. The i9300 also gets major updates first. Development, I would say, is about the same for both though.

I'll try to reply in a nice way before you get flamed by someone. The quad core version (International) does not support LTE, hence we have the dual core setup which does support LTE. You can use an international device on ATT and T Mobile minus LTE. If I recall correctly you may not even get HSPA + either but I don't know if that is true or not.

Damn you beat me to it.

Slight correction. There is a quad-core Exynos that supports LTE. Korea got it, but it wasn't completed by the time the US variants were in full production.

Because the LTE radio is separate from the Exynos SoC. The Exynos itself does not support LTE. Think HTC Thunderbolt. What this results in is horrible battery life. The Galaxy Tab 7.7 did the same thing with the Exynos dual-core, adding a separate LTE radio with the Exynos processor. If you need LTE, you're better off with the Snapdragon S4 (which is no slouch btw). We're at a cell phone generation where all CPU's perform pretty much the same (current gen meaning S4 - Tegra 3 - Exynos Quad) until you really push them. So again, unless you're benchmarking or heavily gaming, you won't notice a difference.
Also, yes you'll get HSPA+ on AT&T (I'm using my i9300 on Straight Talk), but only EDGE on T-Mobile.

Samsung supports developers. They gave the entire CyanogenMod team Galaxy S II's when they first came out. They hired Steve Kondik (Cyanogen), and they worked with XDA devs to try and fix the ICS recovery perma-brick issue on the SII, Note, and other phones. It's probably the carriers that messed with the software without knowing what they were doing.
if you haven't heard already from previous posts the USA s3 supports lte and the UK one doesn't and we also have 2gb of ram they do not but they have a quad core chip to even it out and to be fair.
