I purchased a galaxy s3 I9305 today. I have rooted it and installed supernexus. It all seems to be going well but now when I go into the network settings and choose LTE/WCDMA/GSM, as soon as I exit it reverts back to WCDMA preferred. I am in LTE reception. The only thing I can think of is my sim card. My sim card is almost 7 years old, I had to cut it down to fit the s3. I have read varying things regarding 4g sim cards. Could this be the reason?
Wrong forum

You should be on the I9305 thread, not the international version one

Yeah, you have to get a contract with a provider which supports LTE...
!!!!THE CONTRACT MUST BE SUPPORT LTE TO GET LTE!!!!
Without this you cant get LTE....

I am interested in picking up this phone when it launches on Verizon, but I have not owned any Galaxy device before so I'm wondering how ROM development works. Is it carrier specific and I can only get ROMs for the device on my carrier? I see that the S3 is launching with some versions having 2gb RAM, etc, so just wondering which ROMs I can use. I see that there are a ton of different versions for the S2 so its along those lines. Thanks for your response.
In common it is not carrier, but network specific. The lte versions use another board with a dual core, weaker gpu and 2 gb ram.
For sure roms for the international version won't work there, except it is multi device and also made for the different board.

So in the case of the S3, all the LTE versions of the phone will be able to use the same ROMS? It seems this is a new problem "development fragmentation"

its not new
i have a cellphone repair store and am addicted to new cellphones and trying them out. i currently have the i9300 and love it, but am wondering if there would be anyway to hack it to receive 3g/4g T-Mobile USA. I have switched over back to T-Mobile because they have the best speed for money and coverage ratio where i live. I also have the galaxy note sgh i717 and have it rooted and running ics with the blaze radio hack and it works beautifully on T-Mobile. So what im asking is, will there be a way to flash a radio the same way it was done on the note for the i9300? i really like the way my phone is and prefer the quad core over the dual core that will be coming out here in the us. I don't want to have to sell my international i9300 to get the USA T-Mobile version just so i can have working 3g/4g. Im Hoping for a answer yes you can flash a radio and someone can try to do it. I wish i had more time to play around with these things and be more knowledgable about what im saying, but with my job and two kids i try to learn as much as possible.
Nope. The hardware for the international version doesn't support LTE. Unless you're a superDev and manage mod the system on a chip support it, you'll have to use the US version to get 4G.
It's only the the main reason that the US version isn't getting the quad core. Not that the S4 + 2Gb of memory isn't just as good if not better than the exynos.

What about the hspa+ or even 3g on T-Mobile. I can't see the note that has the same bands as the i9300 being able to do that why not the i9300?? I guess maybe I'm missing something?? Cause the only thing missing is the 1700 band. From both phones and they added it to the att note somehow

He's not asking about LTE, he's asking about getting T-Mobile 3G. I'd like to know if this is possible as well....

No.
The AT&T Note has an SoC that has the 1700mhz band. It is the same SoC that is in the T-Mobile SGSII.
The international Note has the same SoC as the i9100 and i9300 and it does NOT have the 1700mhz band, and it never will.
The only way is when tmo start reusing the 1900 frequency for 3g later this year.
Apparently they are trying it out in some places already.

I really hope they go widespread with it because I was in America two months ago and tmo was better than at&t for pricing etc. And I'll likely be going back again and wanna use my phone there on tmo preferably.

Haha yeah it is much better. I have been using mine on T-Mobile and 2G isn't the worst thing in the world, especially when I'm around wifi all day long at school and home, and you can't even get the T-Mobile versions anywhere here.
Sent from my GT-I9300 using Tapatalk 2
here is an interesting link showing these 1900 locations coming up http://www.airportal.de/
I don't think there is any hack or mods, just have to wait for T-Mobile to expand their 1900mhz coverage.
Luckily, I'm in the area where T-Mobile offers 1900mhz coverage and I can connect to hspa+ on my i9300. It's so much faster than what I'm used to when I was on AT&T. I was only getting 0.5-1.5mbps on AT&T but now 5-6mbps on T-Mobile. When I'm in area that lacks coverage, I do get only EDGE though which is pretty darn slow

Unlimited 4G plan with no cap or throttle.
I'm probably going to switch i9300 to new tmobile branded note 2 or S3 though. There is no coverage of 1900mhz when I'm around home area. Using EDGE is so painful...

Yeah.. I'm using the 200 Mb data plan with my i9300. Since we only getting edge for now , it is a waste of paying 25 dollars a month for 4g if we can't use the speed.. I'm in New York Brooklyn , and still can't get any 3g signals...

is the fastest i9300 can go on. Tmobile
Sent from my C6603 using Tapatalk 4
Brooklyn new york here . in nyc ATT is the fastest for mobile data no question about it. I get an average of 6 mbit/s . some times up to 11 mbit/s I tried t mobile and the best i got was edge. under 100 kbit/s could barely make calls. I dont know about other cities or regions but in nyc ATT is king even though they suck .
You'll never get more than 2G. Unless you're in one of the new areas where they have out their new towers. You'll get 2G most of the time... There isn't a "hack" and there never will be... Its a hardware limitation.

Hello I will be receiving S3 tomorrow and I just wanted ask how to setup with AT&T. I have set it up before on my Galaxy Note N7000, is it pretty much the same way except for needing microSIM?

Yes, should be the same. When I got mine a few weeks ago i cut by SIM card down to micro size and put it in the phone. All data settings were automatically detected.

What kind of setup? I just popped in my sim and everything worked fine. I am running the unlocked, unbranded international version.
Cool thank you very much!
By the way do you guys have LTE plans? On Gnote I have LTE unlimited so I could take advantage of 5gb cap before throttle and visual voicemail. Have you guys set the visual voicemail as well? I hope it works the same as on gnote.
Sent from my GT-N7000 using Tapatalk 2
I have the international version so I don't have an LTE plan, I rarely hit my caps anyway as I am on wifi in the office and at home. As for visual voicemail, I use google voice so I wouldn't know.
Thanks again

Dear guys I bought my s3 from the middle east now I live in New York and with t mobile I only get edge on my data connection. I searched the web and xda but couldn't find a useful solution pleas help me with what is possible to do. if I rooted wich radio and Rom would work.
Thank u all already.

EDGE is the best you'll be able to get with T-Mobile. Your international GS3 doesn't have the 1700MHz band needed for T-Mobile 4G.
Your options are to live with it, switch providers and go with AT&T or sell your GS3 and buy the T-Mobile version.
Bellow is a screen shot from wiki pediatrician for gt-i9300 base bands it includes all almost there must be a work arriund to get 4g

I would say wait few more months t-mobile already started rolling out H+ for 1900. So in few months we will be able to use high speed data

Sell it and get the t-mo gs3 version, you'll need 1700 mhz umts to be able to get the 3g (fake 4g) on t-mo. And this is hardware is no root or magic to change it!

I just want to know if my Galaxy S3 will work with T-Mobile, because next month I will go to NY, Orlando and Miami. I want to buy a T-Mobile sim and use it on a prepaid plan. I'm Brazilian and my S3 is the international version, GT-I9300. It will work well? Will I use 3G data normally? Thanks.

everything will work well, T-Mobile is a gsm network carrier and sgs3 i9300 is too the same.

Yes, as long as you are buying the SIM in the US, it will work just fine.
