Sorry, loooooooooong thread and short attention span! :)

I have a UK SGS3, currently on the T-Mobile network but as it's an unbranded phone I assume it should take any SIM. If I'm travelling in the USA and I take my phone with me, what networks can I use it with for USA HSPA+ data? I'd probably just get a local SIM rather than using it for roaming data.

From the specs, it supports:

GSM, HSPA+21

EDGE / GPRS (850 / 900 / 1800 / 1900MHz)

HSPA+21 (850 / 900 / 1900 / 2100)

[Galaxy S III General] Baldilocks:
AT&T Network (and any of the pre-paid carriers that use AT&T's network). T-Mobile USA does not yet support those HSPA bands.

Does anyone know if the international version is for sale in a store in New York City? Or is it only available through the internet from sites like Expansys and Negri?
[Galaxy S III General] :
Im in Chicago and i picked mine up at the store here. they also do shipping too. The store is called Popular Elect.

You need this...

http://www.att.com/shop/wireless/plans/prepaidplans.html

It's the closest thing we have to PayG. You either get unlimited voice for $50 (per month) or 250 minutes for $25. You need to add $25 for 1GB of data to either of the two voice plans. I think data over the 1GB is $10 a GB but you'd need to confirm that with AT&T. You can pick up a micro SIM from any of thier corporate stores or an authorized partner when you arrive.
[Galaxy S III General] Lucasm93:
Thanks, but I'll be in NYC for only 8 days and I'm a little cautious about the shipping time and if it will be delivered to a Hotel address. If I can't find any stores I'll order from Expansys.
[Galaxy S III General] andrewilley:
Many thanks for the info. That sounds like a good option for me as I'll be in the US for nearly three weeks, and my roaming charges just for calls/texts via my UK contract plan would probably work out in the region of $50+ anyway. I suspect it'll actually be cheaper for me to use that $50 plan to phone/text to UK mobiles than it would be to use my own roaming contract too.

I have a few questions about actual operation, if anyone here can answer? (sorry if this starts to get off-topic)

1) Does the $50 pre-payment give you $50 worth of credit on the account, which then goes towards any calls or texts made outside of the free allowances? Or is it just a $50 charge for the plan, and anything else is on top of that? For example, if I call a UK mobile phone (which is quoted as $0.49/minute) will that fee come out of the initial $50 balance, or would I have to pay it as an extra payment on top of the $50 - and if so, how? Oh, and it mentions something about a 10c/minute fee in addition to the 49c international rate on the $25 contract - does that apply to the $50 contract too, or is the 10c part included in the free allowance?

2) Same question for outgoing international SMS and MMS (which are charged at $0.25 and $0.50) - is that all I would pay per outgoing text message to a UK mobile phone, and does it come out of my $50 pre-paid balance?

3) How would incoming calls (probably from the UK too) be charged to me, do these count within the unlimited minutes. i.e. so there would be no fee (to me) for receiving calls, even from a UK number?

4) Same with receiving SMS or MMS from UK phones, would receipt of text or picture messages be free (to me) within the plan?

5) The $50 plan details in the link above seem to imply that unlimited data is included within the basic $50 fee, is that correct, or do I have to pay for a data bundle on top (as with the lower plans)?

6) Finally, are there any settings that I'll need to change on my UK phone (SMS service center, MMS sending details, internet details, etc)? Or will AT&T send that info directly to the phone when it connects?

Actually, I wonder if there might be an AT&T forum somewhere to ask these sort of questions of regular users? I'd like to have answers to all the problems I'm likely to encounter before I get to the USA, as I won't want to spend a lot of time sorting stuff out once there.

just bought the international version in marble white, only 625 USD, and I thought it would be expensive. :rolleyes:

anyway anyone have tips and tricks to make this badboy sing on Att network?
[Galaxy S III General] :
Same here. Thought it would be expensive too. I got mine for $559 + tax. Just follow the OP, Those are really the only settings suitable for this device here in the States, which i found the phone automatically sets those APN settings anyway with my LTE sim card that im keeping due to i have a One X as well.
[Galaxy S III General] SlimJ87D:
Yeah, read the OP.

[Galaxy S III General] BarryH_GEG:
1) Or is it just a $50 charge for the plan, and anything else is on top of that?

It's $50 for the plan, everything else is additional. It's monthly too so you'll need to cancel it when you leave.

2) Same question for outgoing international SMS and MMS (which are charged at $0.25 and $0.50)

Anything AT&T lists as "PPU" is outside the $50 for the plan.

3) How would incoming calls (probably from the UK too) be charged to me, do these count within the unlimited minutes. i.e. so there would be no fee (to me) for receiving calls, even from a UK number?

Correct.

4) Same with receiving SMS or MMS from UK phones, would receipt of text or picture messages be free (to me) within the plan?

Correct.

5) The $50 plan details in the link above seem to imply that unlimited data is included within the basic $50 fee, is that correct, or do I have to pay for a data bundle on top (as with the lower plans)?

The unlimited data component is only for non-smartphones. People here actually used it previously with the i9100 but AT&T's been constantly flagging the i9300. So you need to add a data plan.

6) Finally, are there any settings that I'll need to change on my UK phone (SMS service center, MMS sending details, internet details, etc)? Or will AT&T send that info directly to the phone when it connects?

It should pick up the APN settings from the SIM. There's a thread going on the correct APN settings for an i9300 that's been imported to the U.S. so that would/could apply to you too. See how it works out of the box first.

Actually, I wonder if there might be an AT&T forum somewhere to ask these sort of questions of regular users? I'd like to have answers to all the problems I'm likely to encounter before I get to the USA, as I won't want to spend a lot of time sorting stuff out once there.

AT&T is like 3. Friendly, but useless.
[Galaxy S III General] Baldilocks:
Yeah, the i9300 only works with Unlimited Data on a monthly post-paid plan.

Put sim in dumb phone 07/11/2012.

Put sim in GS3 on 07/13/2012. Everything is still working fine.

My phone still shows as generic on the att site under my att / wireless.

Under support / wireless it shows my old dumb phone?

I guess I can stop updating about this. I believe I am in the clear. I will update if something negative happens.

I bought an unlocked Galaxy S3 from an online seller to use with AT&T and received a Galaxy S3 with Vodafone Germany customization.

I would like to flash the I9300XXBLG8 UK firmware but I am unsure what I should do with the CSC and Modem.

If I understood it right, selecting the PDA option on Odin will not change CSC and Modem. I would like to change the CSC to get rid of the Vodafone Germany customization and I think I need a Modem that works well with AT&T.

Can you please help me explaining me what to do?

Thanks!
[Galaxy S III General] Simmo3D:
If you flash the PDA in Odin, it will flash the CSC and Modem as well.

You will need to factory reset the phone once you have updated.
[Galaxy S III General] Baldilocks:
Just flash the PDA with ODIN. No wipe or reset required.
[Galaxy S III General] luigig:
Thanks!

I just flashed the PDA and all AP, CP and CSC got updated. No need to wipe or reset as you said.

Before with the Vodafone Germany firmware, on occasions, I saw some messages in German although the language was set to English. Hopefully now with the I9300XXBLG8 - UK firmware it will not happen any more.
[Galaxy S III General] luigig:
Using Kies today I saw two things that are unclear to me:

A message saying: "Your device does not support software upgrading via Kies". Is that normal or a symptom of a problem?

My CSC says LG8 (VD2). It is the VD2 that worries me because I think it is related to the Vodafone Germany customization I wanted to get rid off.

Can you please shed some light?

Thanks!
[Galaxy S III General] ghus:
Recently got an international S3 and using it in ATT. I have the latest firmware and modem I9300XXBLG8. I am experiencing the following problem with ATT occasionally mobile data connection just freezes up. I still see the H or 3G icon in taskbar and the inbound and outbound traffic arrows are blinking but no internet connection at that point. Browser and apps timeout. To resolve it I have to toggle mobile data and when it connects again everything works fine. I have tried a few APN settings just in case but no resolution, (what worked so far is wap.cingular and phone APNs). When I tried pta APN it would not even connect so not sure if I need to call before I enable it. I appreciate your help in advance and in case this has been addressed somewhere in this huge thread my apologies.

So with a GoPhone Prepaid SIM we can get unlimited data on international phones?

Awesome.

Going to the US soon and I want to get mobile data on the trip, planned to get 25$ plan + 1GB Data plan, but now I go for unlimited.

But when I walk into the at&t shop I better don't show my One X to get the SIM :D

Hopefully they'll sell the SIM as a Micro SIM

I was thinking about buying a nexus and not the extending my contract, but I like tmobile so another 2 years with them isn't that bad
[Galaxy S III General] Flo95:
Mhm, that sucks that no one knows for sure if the One X or other international phones (GSM Nexus is available in the US though Google Play) that aren't available in the US get unlimited data with the 50$ monthly unlimited plan or not.
[Galaxy S III General] andrewilley:
I've been investigating this too (UK user, visiting the US for two weeks shortly) and most people seem to say the GoPhone pre-pay plan doesn't allow smartphones on their unlimited data plan without adding a booster.

It seems that AT&T offer 'unlimited data', but only on the condition that you have an older phone which can't really use much data. Technically not inaccurate marketing I suppose, but it is rather like having unrestricted speed limits on main roads but on the condition that you can only ride a pedal cycle.

Whether they can detect a European Galaxy S3 is another matter (most of the posts here say they do detect it on the GoPhone plan) but I'm not sure I want to risk the hassle and time-wasting of trying to sort it out while I'm away.

Anyway, there's an AT&T Store almost opposite my hotel in New York (gotta love Google Street View!) so I intend to pop in there as soon as we arrive and give them $50 for either the unlimited plan, or the $25 plan plus $25 for 1 GB data. I started a thread in the AT&T forums on the subject, and so far I think I'm possibly more confused than when I started! :confused: See http://forums.att.com/t5/Prepaid/A-...-three-weeks-some-questions-about/m-p/3261723

By the way, more suited to this thread, but what are the thoughts on AT&T Micro-SIMs? There has been some talk of needing to ask for a specific type (apart from the size) in order to get data working at the best HSPA+ speeds on our phones, and I'd like to know what to ask the store for (assuming the shop staff have a clue what I'm talking about of course).

And also, there has been some discussion of using the 'Phone' APN or 'MediaNet' APN, any idea if either type is specifically needed for GoPhone vs post-paid, or should I just accept whatever the SIM installs?

I want to get all the questions asked and answered before I leave home, so that when I get to the US (vacationing in New York and Florida) it should just work as soon as I put the SIM in rather than needing lots of messing about. (I have already installed FastDormancy Toggle in readiness, just in case I need it)

[Galaxy S III General] Brolio:
I can only share my experience on a post payed ATT plan. What i did is went in and before i got my S3 told them i was getting an iPhone 4g from a friend and played dumb so the salesperson said "since u have a 3g now all you'll need is a micro-sim call this number when you need the sim activated." When i got the S3 just put it in, called customer service and used the default apn. Though i still have my iPhone data plan i don't know how helpful this will be to you. But i get reasonable data speeds of 5-7mbs down and 1.5-2.5 up which is comparable to what my friend gets on his iPhone. Its more than enough for Pandora which is all that matters and seems to be about the norm overall. I was acualy going to go into my local ATT and ask if FastDorm is enabled in my area but i'm guessing they're just going to look at me like i have 5 heads.
[Galaxy S III General] xsteven77x:
I live right outside of pittsburgh and NEVER see speeds higher than 10 MB/S on a good day. Kinda sad that all these people post 50+ speeds and HSPA+ is actually better in pittsburgh than LTE :( :( :(

I am currently on T Mobile without contract.

This is what i m planning to do:

1. Buy a new SG2 from at&t and get into contract for 2 years

2. Keep the SG2 box as is and pop the SIM card into my dumb samsung phone

3. Activate the non smart phone data plan

4. Sell SG2 on ebay

5. Buy an international Galaxy S3

6. Pop the SIM card from dumb phone to SGS3

Can I sell the GS2 like this?

Do I need to activate service on GS2 before selling?

If I sell GS2 will the new user have problems when he pops in his SIM card?

Will att detect new user and impose him on $30 data plan?

Please let me know as I am noob to all this.
[Galaxy S III General] kirdroid:
Since you will be signing the two year contract with sgs2, i think you can't change into non smartphone plan even if you don't use sgs2 and use a dumb phone. I think the non smartphone plan will work only if you are not on contract.

Im not completely sure of this but i assume if you get into a contract they will not remove the smartphone data plan from your account.
[Galaxy S III General] SlimJ87D:
You can. My friend works in the phone area at Sams club and knows a little about all the carriers. I had a smartphone plan and downgraded to a median unlimited.
[Galaxy S III General] ceo.mtcl:
Yes you can change it. I did the exact same thing last week. I upgraded and sold it off craigslist for over 500 and bought international GS3. I've even mentioned this in my first post.

You can always change data plan to any one you want as long as the phone you are using is not detected as a smartphone. Att doesn't care.

Thanks for the info.

One more question..

Do I need to unlock the SGS2 before I sell it?

If new user pops in his at&t SIM will there be any issues for him?

Thanks Again!!!
[Galaxy S III General] kirdroid:
If you unlock it you can sell it for more and the phone can be used on any gsm network (3g data speeds may vary depending on what frequency other network uses).

But no you don't have to do that for using it on ATT. Just poping in an active ATT sim will do.
[Galaxy S III General] ceo.mtcl:
i agree with what kirdroid mentioned.

You can sell it the way it is if the user is only going to use it on Att network. however, if you call Att and tell them that you are traveling internationally, they will unlock that phone for you for free.

For some newer phones like galaxy note Att doesn't provide unlock code. To unlock these phones you may contact tried third party unlocking sites like cellunlocker.net

By unlocking you will be able to sell it for higher price. It's not required on your part to unlock it.

There is an app that sim unlocks it for free. I used it to unlock my ATT gs2. There is a link for the app and how to do it in the att gs2 forums.

Chainfire has one on the market as well as a developer named helroz(this is the one I used)
[Galaxy S III General] ceo.mtcl:
For gs2, you can just call Att and they will provide you the unlock code for free. I've unlocked two Att gs2 like that. Just call them at 611 and tell them a reason (like you are traveling abroad). Unlock code that Att will provide is factory unlock and will work on non rooted phone as well.

However, the software based unlocks will disappear after you do hard reset. It will also need rooting.

If you don't call Att and make this switch deliberately, then just by switching the sim card to this phone will not change your grand fathered data plan. Just don't call Att and tell them anything.

Did anyone ever decide if there is a particular modem which works better for HSDPA+ than any others when using a UK SGS3 on AT&T/GoPhone in the USA?

I have XXLG8 modem and XXBLG8 firmware (latest UK) on my phone at the moment, but I might stick a few other modems onto the memory card so I have some instant options should I get any issues once I get to New York. Swapping is a simple quick flash via CWM I think, so I assume it should only take a few seconds?
