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.

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
Hello,
I have an AT&T i777 rooted running Shostock2 and I am looking to buy the international version for my daughter. Trying to separate from my contract lockup with AT&T.
What exactly is the difference between the different 9100 models (G, T, etc), and is there a better one among them? I want the most reliable one (in case the different processors makes any difference in that regard) and also one that would allow rooting and custom ROMs.
Also, it needs to work with any U.S. carrier at the highest speed that they offer. I saw one on eBay but it says "Will not work with T-Mobile or Simple Mobile 3G/4G speeds" and I am not sure why.
Thanks in advance.
Imo u'd decide to get i9100G as it powered by TI OMAP SoC which mostly being open sourced to support better & early development. But if u want it to come with NFC featured i9100P is.

I wonder how much of a "deal breaker" should NFC capability be. Looks like it is very difficult to find a P model in the US. I could probably go with T-Mobile one but from what I read it is a bit inferior to the AT&T and International models.
Then again - what if I do want the T-Mobile's 4G speeds....tough decision

NFC=android beam, mobile cc payments, transferring files by tapping.
And maybe speed will also sacrifices power (batt), like 2G vs 3G/H+..
Intl i9100 maybe ur easy deal but maybe 2nd P var.? Ebay?

Well, first of all, it's for my daughter, not me , she is the one who needs to be patient. But her old phone (Samsung Solstice 2, which is a piece of crap) is dying, it gets stuck all the time, turns off by itself, etc. She needs a new phone.
Second, I am not a big fan of Sony phones and/or LG phones. We had LG before (not a smart phone) and it was too a piece of crap. I am 100% convinced that in recent years, when the Smart Phones started to become so popular and companies started making so much money off of data plans, the manufacturers deliberately made the 'dumb' phones crappy, there is no other explanation for it.
I believe that Samsung and HTC are the best phones in the market these days (Android), not really sure I could like a 'Sony'.

You have a few options, but just keep in mind that the standard i9100 has the largest userbase, the most external support, and the quickest official updates from Samsung. In fact, these "similar yet different" models of the first Galaxy S were the first to lose official support. The i9100p may sound nice with NFC, but one feature isn't worth potentially losing out on updates. The i9100G uses a lesser version of the SOC found in the Galaxy Nexus. Unless the storage is a concern, the Galaxy Nexus would be a better (and cheaper) option in this case.
So, that leaves you with the vanilla GT-I9100, and it's still a kick-ass phone IMO. Comes in several colors but black and white are the easiest to find. Bonus if you get the black one, it will work on AT&T's medianet plan, which is truly unlimited data, no throttling, and no wifi hotspot restrictions, and it's $15/mo (or $10/mo if you have unlimited text). I've been using this for the past year and change. Added myself to my wfie's family plan and it cost us $9.99/mo for the line, $10/mo for the data, and that was it. I'm on pace to use over 30GB this month and I don't care

You could maybe send a PM to a helpful guy called ctomgee.He knows about US phones and could advise you best variant,providers etc.
Once you get a phone,you can then install custom roms etc,which gives the phone a new lease of life.

About phones working or not working with T-Mobile in the US, this is why; T-Mobile (at the moment, for their overall network) uses AWS for high-speed mobile data. AWS requires both 1700 mhz and 2100 mhz to get 3g/4g, as it uses one frequency for uplink, and the other for downlink. If one phone is not capable of receiving one of the frequencies, then the best mobile data speed the device will receive is Edge.
Now, they (T-mobile USA) are currently in the process of repurposing the spectrum of the 1900 mhz band they use now for Edge data and voice, to use it for high speed data instead. This will allow some phones that currently only get Edge speeds on T-mobile USA's network to get their "4g" speeds. That includes many of AT&T's phones (if they're unlocked), and the i9100, which receives high speed mobile data on 850 / 900 / 1900 / 2100 mhz. (notice the missing 1700 - which is why it won't necessarily get high speed on T-mobile USA's network... unless the market you're in has already had the repurposing of the 1900 mhz band)
However, this repurposing has already only happened in a handful of markets, though the rollout is currently underway.
Hope this makes sense.
EDIT to add:
Also, about the different I9100 variants - there are minor differences between the I9100, and the variants I9100P/T/M.
The P variant includes NFC, the T variant has a slight variance with the SAR values for the radio (so modems specifically for the T model work best for that model), and the M variant is simply a branded regional variant for the Canadian market (as far as I can tell). The CPU/GPU/SoC are all the same for these 4 variants.
The I9100G has a completely different CPU/GPU/SoC chipset, so firmwares, kernels, and ROMs are NOT compatible between this one variant, and the four listed above. But for most users, the performance between this variant and the others are very similar and comparable.
That said, they all have the same antenna/radio hardware, so what I said above regarding data speeds on T-Mobile USA above applies to all of them. This also means they all work just fine for high speed data on AT&T's network.
Ok tom.
I came in here to add to my previous post about which phones (and why) will/will not work on T-Mobile, but Tom beat me to it, so I'll just simply add this:
If you want 2G/3G/4G now and in the future, get the Galaxy Nexus as it's pentaband.
If you're ok with 2G and don't mind waiting on 3G/4G, get any phone, like the i9100, that supports the 1900mhz band. T-Mobile stated that they anticipate their 1900mhz refarm to conclude in mid-2013 and will cover ALL 229 current AWS HSPA+ markets.

Thank you for a broad response. I learned something new!
We don't necessarily want to be on T-Mobile, I mentioned T-Mobile because I want to have options...I don't want to be locked to one carrier and T-Mobile offers a great deal with "bring your own unlocked phone, get a sim card with unlimited text/data". So it was just brought as an option for us to have.
In any case, I did offer a T-Mobile (T989) version to my daughter, she "kindly" refused...she does not want to see any logo on her phone . She also doesn't care much about the NFC, even though this can be 'fixed' through an SD card solution if (as she says) "The government will force you to have NFC..." , so I am now just looking for a good deal on a I9100 version.
BTW - what is the Nexus?! I am not familiar with it at all. Does it also come in branded (AT&T, T-Mobile, etc) as well as unlocked?
Thanks again.

Nexus is the 'pure' android phone. Comes with stock android. No OEM bloatware or UI like Samsung's TouchWiz or HTC's SenseUI.
The biggest advantage of nexus phones however, is that they're the first to get any android update.
And yes, you do get it unlocked as well.
Hope it helps.

I don't know why that guy differentiated between the black i9100 and the white i9100. As far as I know, there shouldn't be a difference between them, unless someone can provide us information otherwise.
EDIT: ah. I was curious and did a search on this. Apparently many have reported that their white i9100 gets flagged as a blackberry by AT&T for some reason, causing a bump in their data plan to the 2Gb tiered data plan. I didn't know this. I find that curious.

Interesting. I tried Google for 'difference' between them and didn't see anything. It sounds odd to me, to say the least. Question is - did those who report this issue also had a black one, to compare how AT&T "reads" their phone. Really doesn't make sense, but I am curious too.
Figured I'd come back and answer some questions, but thanks again to Tom for taking care of that To elaborate a bit further:
Whether or not your phone will work on AT&T's medianet plan is determined by whether or not they have loaded the device's IMEI database into their system. If they have, then they can detect your phone and will not allow medianet access. The international SGS3 and the Galaxy Nexus have already been detected. The white i9100 (SGS2) is detected as a Blackberry as it has a different IMEI database than the black or pink models. However, if you do get a device to use with AT&T medianet, understand that they can change this at anytime. Just ask Nexus and SGS3 owners who got caught 2-3 weeks ago
Based on your needs, there are two phones that I would recommend, and here's the links to the recommended purchase places.
Galaxy Nexus ($349)- This is the official Google phone, relatively cheap, always has the latest version of Android. Downside is that is only has 16GB internal storage and no support for MicroSD. 720p screen
Samsung Galaxy SII (black - $470 / white - $530)- The flagship android device from 2011 by most estimates, still a solid phone for today. Comes with 16GB internal, official support for 32GB MicroSD, but will support 64GB MicroSDXC unofficially. , 800x480 screen though. The black one will work on AT&T medianet, white one will not.
If you use on T-Mobile, or a T-Mobile MVNO such as Simple Mobile or Straight Talk w/TMO sim, you will get full 2G/3G/4G access with the Galaxy Nexus (before, during, and after the refarm). As for the SGS2s, you will get full 2G everywhere, but no 3G/4G in areas not yet refarmed. In areas that are refarmed, you will get full 2G/3G/4G. T-Mobile says that the refarming will be complete by mid-2013. You can check the current status of the refarming here:
http://airportal.de/
If you want to get her something top of the line instead of those former-fastest phones, you can look at the SGS3 unlocked, or wait 9 days to see the official unveiling of the new Nexus phone. Who knows, we may even see a $50 price drop on the Galaxy Nexus
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.

Hello,
Random thought here but a good one. I am an electronic technician and I'm a little into Android but super into it like I used to be due to time constraints these days.
What I am asking is, is it possible, and I don't mean physically, I can do that already. I mean software wise to change the chip used to pick up certain signal bands with another one that picks up different signal bands and use a phone with a different carrier? Or is there some sort of programming specific to each phone that is tailored to use those specific bands for communication? Or does Android just handle data and texting the same across all phones?
Thank you for answering.
@BlueForce64
SIM cards allow your phone to work on a specific carrier's network, such as Verizon or AT&T. Hence technically seen it's the carrier who owns the phone. And: It 's the carrier who decides which band is used, it's NOT Android.
In order to use a SIM card from a carrier that's different than your current one, your phone must be carrier unlocked.
No, that's not what I mean. I mean on the circuit board, if I changed the Qualcomm band chip that your phone uses to pick up those specific bands, can you use the phone with a different carrier if I removed the one for let's say, Verizon, and swapped it with a Qualcomm chip that can pick up the t mobile bands.
As I said, I am an electronic technician. I work on military, space, medical and other electronics on a component level. I have access to a wide range of professional soldering/desoldering equipment. I change 144 pin FPGA's, ball grid array chips, surface mount components on a daily basis.
What I am referring to is the components on this link. Specifically steps 8 and 9 where it highlights which components are which.
https://www.ifixit.com/Teardown/Samsung+Galaxy+S9+Teardown/104322
I have the ability to change any of these chips with my profession and wondering that if I were to change them, can I bring any phone to any carrier if I know which version of which Qualcomm communication chips are used for which carrier.
I was able to flash my XQ-BC62 (US) model with the XQ-BC42 (JP) firmware using newflasher. Everything seems to work OK except the mobile radio. The radio is completely disabled (as reported by *#*#4636#*#* status screens), not just unable to connect. The hardware is still fine since flashing back to XQ-BC62 firmware gets a signal again.
Unfortunately I need to use XQ-BC42 as the other firmware images are missing the VoLTE support for my JP carrier and it fails to provision. At best I can force it into data only mode by setting radio to LTE only. The carrier does not support 3G at all.
Extra steps I tried:
- Perform factory reset after flashing
- Swap out the files for the modem firmware from the US firmware and reflash
Has anyone had luck with this, or are there any additional steps I might need to try?
This phone keeps getting worse. I literally bought it to use in the US and Japan. Sony support said it is officially unsupported by all US telcos. No SA 5G, no VoNR, no VoWiFi. Now I hear that it doesn't work in Japan?!
I already know it's close to useless in French Polynesia despite having all the right radio bands.
You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

Might you elabortate a bit on this?
So which modell? which provider? comeing form a country where all of these 5G related features are just in development this would be nice to get some further informations on this topic.
VoWiFi is highly likely a provider "problem" - as we have another thread here where these "offical support" statements are at least highly questionable, as we have multiple users here using VoWiFi.
Here is one example of an answer one got from sony
T-Mobile USA Volte and VoWifi support?
Hey XDA, is USA model XQBC62 work with T-Mobile Volte and VoWifi? PS: my old Xperia5 II wasnt able to work and returned back to Sony week later (sad)

Which carrier are you talking about? using a second sim card or use roaming capabilites? keep in mind that not all providers might allow access to all availeable networks based on there roaming contracts. just to give you a idea check these information from one of the providers over ther

I took my device through several countries already not one having trouble with connectivity as long as the bands are supported and there.
On my trips to japan i head several different devices with me over the yeras, beside the xperia, not once having problems as long as the bands where supported / one is using a local sim - card.

Unfortunately I need to use XQ-BC42 as the other firmware images are missing the VoLTE support for my JP carrier and it fails to provision. At best I can force it into data only mode by setting radio to LTE only. The carrier does not support 3G at all.

Did you try to get in contact with the japanese carrier asking if they are supporting VoLTE for devices from other markets?
Maybe the easiest way would to switch your carrier at all.
If you are willing to dig around more you could try something like this
5II/1&5III VoLTE patch. [Guide to release the root]
In the Xperia user group in cafe.naver.com/x1smart I'm HTCMAGE. Last year, Xperia 1II. How to activate VoLTE. After the guide version...

But you will need the profiles for your vendor. One could play around and try to integrate these profiles into your XQ-BC62 Firmware and see if this would work out. But well - keep fingers crossed that you don't brick anything.

You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

No, they don't support overseas models. I don't know if it's ignorance around the security or an attempt to prop up their own phone sales. Both are honestly believable over here.
This is the only reasonably priced major carrier plan with unlimited international roaming included (ahamo from NTT Docomo). Not being able to use the 1 iii sucks but I'll just write the 1 iii off if it can't be fixed and continue using my JP variant 1 ii.

sad to hear - but just out of curiosity:
Why did you get yourself the "American" Variant? Docomo has, as well as softbank, there own supported devices. Kind of similar to TMobile US. Sounds you are spending most of the time in japan. I know that the Docomo version isn't so well supported regarding updates though ...

I have the US model - the same as this thread topic.
It's Sony tech support themselves that told me that there is no carrier support for the US model in the US. It was such an incredible conversation that I saved it. An excerpt:
(Adrian) said :I'm asking you this because at this moment Verizon is currently the only U.S. carrier that supports 5G on the Xperia PRO model. The 5G network service is
not currently available in the Xperia 1 III model and this is why you're getting that
issue. In this particular case we recommend you to check with your phone carrier
if there is a way for them either to provide a different network service or if there is
a work around on their system for you to use your Xperia phone with their service

Don't repeat Sony's claim about 5G being in development. T-Mobile has been running SA 5G where I live for nearly 2 years. I've done side-by-side comparisons between an older phone with SA 5G and my Xperia by swapping the SIM. The XPeria has a lot of "no service" problems because it's using SA 5G channel aggregations without having SA 5G. There's another thread on this - Sony has explicitly disabled SA 5G on all US NR bands. https://cacombos.com/device/XQ-BC62
The Sony phone was unstable roaming in PF and could not see several 3G, LTE, and 5G bands that were available to it. Again, an older phone worked better. I used a much more modern coverage map than your 2017 document.
I haven't been to Japan with this my Xperia yet due to COVID restrictions, but I normally spend ~2 weeks a year there. I know my old phone works well there so I'm going to be mad if a new Xperia is stuck looking for old 3G cells that only exist in subways.
I have an XQ-BC42 that I'm using in Europe with 5G working (which isn't supported officially).
All I had to do was flash the XQ-BC42 firmware with the following 3 files replaced by their equivalents from the XQ-BC52 firmware:
* modem_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
* modemst1_X-FLASH-ALL-4BA8.sin
So in your case you just have to take the 3 files above from the XQ-BC42 firmware and combine them with everything else from XQ-BC62 firmware and flash that.
From what I've gathered, assuming your phone has XQ-BC62 firmware on it already, it might only be necessary to flash the XQ-BC42 modem files and nothing else, but I haven't tested this.
I'm assuming you can swap other files too but what definitely didn't work for me was the oem .sin files from another model's firmware. I don't know if there's something incompatible about the XQ-BC42 compared with other models but using non-XQ-BC42 oem .sin files disabled my radio completely.

no, i am not saying it is under development. The standards are there. How ever - in different regions some of the 5g is still not rolled out / will never been seen (mmWave,SA 5G - at least for private customers).
Well i read the message you quoted a bit different - and i would love to know what other carriers have to say about that.
I personally would find it completly unlogic to sell a device like the Pro, which is said in your excerpt, to have 5G support on Verizon - but then sell the 5G capable phones which have this deactivated at all.
Supported Major U.S. Carriers: Verizon (5G), T-Mobile (4G), AT&T (4G)*
*As of 9/27/2021, please consult with your network operator to ensure compatibility with their network.

Might be, that t-mobile is using some more advanced features. how ever: here where i live most phones up to now don't support 5G SA, at least thats what the carriers say, as there are updates needed to make this work. So we will see here some selected phones using 5G SA - as the providers are working together with SOME of the major OEMs.
You can know ask who is responsible for supporting 5G SA or providing updates... As much as i got from t-mobile usa, they where always not really open to devices, which they don't sell directly ....

I happened to be in the US at the time to pre-order and it wasn't clear that Sony would release an unlocked dual-SIM model for the JP market. I checked the radio bands before purchasing but all of this client provisioning stuff is new to me. Seems like all these laws were made to force carriers to unlock their phones / allow any standards compliant phone on their networks, and then they find this loophole with provisioning that requires more than just a SIM card...

Unfortunately this didn't work. But I did learn that the radio problem isn't an issue with the firmware itself.
Immediately after flashing the mobile radio was OK and I could use it with my alternate SIM card. As soon as I inserted the JP SIM card it triggered OMA client provisioning and killed the radio. After this happened not even the US SIM card would work anymore, and any radio related configurations can no longer be changed.
My hypotheses at this point are either (a) the client provisioning step found something off with my phone and forced it to lock down (not sure if client provisioning has the authority to do this though), (b) the client provisioning is interacting with the modem firmware in a JP-specific way and the US modem firmware is borked by this.

Other than the issue after provisioning the OEM files from the JP model did work for me. If (b) is true then flashing both the oem and modem files might be a solution. I'll give that a try!

Same result, no radio after client provisioning runs and it stays borked even with the SIM card swapped out.

Have you tried with only the modem files taken from the XQ-BC42 firmware? Might be worth a shot.
Also, it might be worth asking on the 5ch thread if you speak Japanese.

I spent a few more days trying various combinations of flashing, factory resets, etc. and finally have it working. I don't know if this is the only way to achieve this, but I can share the sequence I did most recently. This was inspired by the discussions in that 5ch thread - thanks for the link!
1. Install JP variant ROM with full factory reset.
2. Install the JP SIM card and wait for provisioning to finish. The radio stops working at this point.
3. Create and flash a hybrid ROM, using the modem*.sin files from the JP variant and everything else from the original (US) variant. Do NOT factory reset.
4. Set the correct APN (sp-mode.net for ドコモ).
After this both the JP and US SIM cards are working.
@cjmovie
Congrats on this achievement! Hope you can now use your device as you wished!
