Hello! I am deploying to Kuwait for a year and was hoping to get international service on my unlocked SGSII i777 AT&T branded phone. I'll be installing CM7 or CM9 on it, but based on the posts here, there's some reason that it will not work internationally, at least not nearly as well as an International i9100? Is there anyone that could help explain why I would run into issues?
Slightly different hardware. CM7 should be about the same between the two - You will not see CM9 until kernel source for the I9100 becomes available, and even then, the audio libraries may be problematic for in-call audio.

But I shouldn't have any problems with an international SIM?

As long as your phone is sim "unlocked", you won't have issue with international sim unless it doesn't support the bands.
I can verify that I took my unlocked SGH-I777 to UK last week and put the sim card from O2 network. It worked like a charm.. 3G was working too without any issues.
Kuwait use GSM (2G) 900/1800MHz band as well as 3G on 2100MHz.
As long as your SGS2 unlocked, it should work, theoretically.
Band support is (I believe) identical between I9100 and I777.
Main difference is that the I9100 ICS leaks don't do much for us, we need a full I9100 release including kernel source to get ICS.
Thanks for the help, guys. My worries are alleviated
Be safe over there!

Best of luck... Hopefully this trend of things starting to get "interesting" around the Straits of Hormuz does not continue...
i just brought my 777 over to egypt and it is working just fine.

If so, what are the differences? I know AT&T has Skyrocket, but I don't really like how it has a different processor and it's 4.52 inch screen. So can I order that expecting to get the same thing as the Euro SGS2?
It is not exactly the same device, the keys are different, as well as I believe the 4g bands supported, so the ATT version wouldnthave working 4G in europe and vice versa. Also, most ROMs, kernels, and such developed for one are not compatible with the other (there are ways to get around this one though). But the main parts, screen, processor, and other internals are exactly the same, making the ATT version the closest US variant to the original (which is generally considered a good thing)
I've owned both. Switched to this phone because of the amazing screen problems. My friend owns the European version. The only difference is the "apple" button on the European one that the AT&T version lacks.
ATT version has NFC but not enabled at the moment.

How come? And is it possible to enable it?
Well as long as the internals are the same. I couldn't care less about the bands. The Skyrocket just seems crap.
It's possible to partially enable it.
Main differences:
Different buttons at the bottom
I777 has NFC hardware
I9100 has FM radio
I777 has a crippled battery charger (Stock users won't notice this, but those that want to crank the charge current up a bit with a custom kernel will find that it isn't possible - we're stuck at 650 mA, which is stock on the I9100 also, but the I9100 can change it with kernel hacks.)

Actually they support the same bands. Same exact radio even I believe.
Main differences are as Entropy listed: buttons, nfc/fm radio, and charging chip.
There are also a number of minor UI differences in some of the built-in apps, pull-down toggles, and settings. I've noticed voice quality is a little better with my AT&T version (I get less static incoming. Outgoing voice is clearer and louder). Data speeds are faster with my AT&T version. These last two may be due to different modems, SIM cards, and/or account provisioning by AT&T.

Oh oops. The Skyrocket had the amazing screen problems. The problems are explained everywhere in the TMO SGS2 and the Skyrocket

I think the I9100s have smaller TCP buffer settings by default. I remember looking at the settings in SiyahKernel, they were as small or smaller than those of UXKG3 for Infuse, which was notorious for bad network performance because of those settings.
skyrocket is slow vs the s2 speed wise.
AT&T version only has tri-band HSPA radio while international verison of quad-band HSPA radio. So, you may have problem getting 3G outside North America.
also the noise canceling mic is in a different position
Hey there,
been having frequent signal cuts lately after flashing ATT radios on my international Atrix.
However, I did not find any hint about which radios can be used on international phones and which should not.
So, what radio should one use with an international Atrix?

Yeees...actually I did look there, but there is no information given about international devices. Each time someone brings a question regarding international phones, the discussion seems to overhear it.
There is just ATT (USA) and Bell (Canada) radios. It might be true, there exists an older Orange (UK) radio in the unlock thread. However, I started to wonder why there is no update on any other radio but overseas.
You know, either ATT/Bell really suck, making frequent radio updates neccessary, or Orange/O2/*insert any european carreer here* are plain lazy.
Edit: Ahh, right, the signal loss. Yes, I lost my mobile signal several times on Gingermod#4. Well, but everyone there insists on the signal loss being my fault for whatever I dont know reason at all.

Ah, thanks, it is a german atrix btw.
I restored my darkside prefinal backup with faux kernel + ATT .30p radio and everything works fine.
The signal cut issue might be related to using ATT radios and international stock kernels which I used in gingermod#4.
Will test and report
Edit:
Seems like the issue was not kernel related from the start. Freezing "data manger service" and "home"-launcher is not save on every ROM.
Hey, I have the SGS2 HD LTE I757M and I was wondering if anyone knows what the substantial difference between the T989's kernel and the I757m's in terms of cellular reception/management as I am having issues getting AWS to work.
I have flashed the t989's radio and unlocked my phone so I can try my WIND sim in it. I had the t989, and on the t989 it worked flawlessy. I could send and receive messages, calls and I had internet speeds of up to 6 or 7 mbps (which is good for WIND ). On the I757M, I could send and receive texts and SOMETIMES they would go through, where other times they wouldn't. I could make calls after a short delay, but I could never receive them. I could also connect to data services and while Speedtest claims I had 3 or 4 mbps, it was slower than dialup.
I looked at dsixda's kernel at github.org/dsixda and noticed the binary blobs from Bell (a non-AWS network). I did some reading on RIL's I copied the equivalent radio files from a T-Mobile T989 kernel (TeamChopsticks I think?) but that didn't do a single thing haha.
Anyway, that was all I could really think of besides kernel source as the RIL and the modem were the same. Seeing as people here know their way around the kernel better than I do ( I know Java well and a fair bit of C but I never have time to muck around with kernels and when I do, it normally ends disastrously...), I was wondering if maybe any of you had some ideas on how to make AWS frequencies work better as I like the screen so much more than the blueish T989.
Obviously they have slightly different radios as one is capable of LTE while the other is not, but I've heard users of the I727 Skyrocket LTE have much more success with the T989 modem than I was (I also tried the T879 modem and the Blaze modem, but neither worked any better).
EDIT: Also, according to pdadb, they're all based on the MSM8660 chipset, so they should be able to work similarly

I have the same issue !
I'm using mobilicity and I only have CDN Roaming.
i tried all the modems aswell but no luck.
Does anyone have a solution for this ?

I unlocked it by purchasing the code on ebay, placing another sim in it and then typing the code.
you may be able to use the free unlock method used by the skyrocket and the hercules though.
as for getting it to work on WIND, I was able to by copying the modem and modem related files from the system folder on the t989. it did not work well so I ended up selling it.
the s3 is the same build in europe and america, but because samsung couldnt get lte working with their processor in time, they used a different one in the US. most of you know this. europe is finally starting to get 4g right? (took you long enough), do you think well see the exact same model released (with just maybe different radio bands) in both?
as an american phone user, you either buy the international phone and and get development, or you buy the US one and get monster LTE 50mbps.. i want both. its not just our side that would benefit tho. development wouldnt be split between regions, it could all be shared and collaborated. well im asking if you think itll happen, not convincing you why its a good idea lol..
so do you guys think itll happen?
Most probably yes, samsung was not ready with lte based exynos soc when s3 was launched, hence the variation. If you see note 2 the spec is almost same everywhere

Will the different LTE frequencies still not cause an issue then?
With each carrier having there own model?

lol that does raise new problems that didnt exist before.. i dont know what frequencies you guys will use, but i dont think that really matters much.. every carrier will have their own radio im sure. but as long as the rest of the phone is the same, development wont matter.. just as you can flash firmware XXYZ with modem XXAB and there wont be any problems, you could flash SGS4 firmware XXXDA with any number of modems.
its also possible that samsung could release a modem with multi regional support, so all carriers could use it.. but i dont really see this happening.
As well as using different frequencies, the USA uses two completely technologies namely gsm and CDMA.
Maybe in time, the chips used in phones will be small enough to work on all the frequencies/technologies.

They use different basebands and different boot-loaders i believe.
Different Radios. International doesn't have LTE.
As the above poster said. They have diffrent radio hardware, and they also have a diffrent kernel.

Sorry to revive a dead thread, but as I've only just moved over from HD2 to One X+, want to be sure I understand the differences and therefore the ramifications of international vs AT&T - what I need clarification on is other than loss of LTE (as both devices do "talk" on the same 2/3G bands), any issue with using international ROM? Has anyone "risked" loading INTL on ATT device?
TIA for info!
Cheers

you can load an international rom onto the AT&T device, but the rom WILL BE useless, you won't get wifi, audio, gps, ril\data\gsm you'll get display though
to load an Inter rom onto the AT&T device need's some changes to the rom zip...but all in all it's utterly pointless, besides the source for ANY international rom (not the device tree) can be used 1:1 with the AT&T device, so there's no reason for you guys not to have the same rom's as inter, providing the call routing gets fixed
Thanks Lloir, been playing around with ROM dev (thanks to your TUTO) and, while I have compiled both your git as well as CM endeavoru (compiled but didn't boot), not having much luck with data. At least now for certain I need to stick with AT&T based ROMs.
Cheers!
