So I originally had my SGS 2 with Tmobile but I recently unlocked it and switched over to ATT (Don't ask). Since then I have been unable to obtain any internet access at all except WIFI. Would anyone with knowledge of this please way in on this topic! I can do everything else but I have no internet at all.
Thank you for considering this and responding if you do. I know it takes your time away from something else.

T-mobile USA SGS 2 is the SGH-T989. This is the forum for the i9100. Two totally different phones.
Also, the T989 uses different frequencies than what ATT uses... Even if you do get it running, I don't think you'll be able to get better than Edge for mobile data speeds. From what I hear, you MIGHT be able to flash a different modem to use ATT's network optimally, but I can't guarantee that.
EDIT: actually, after a few minutes research, maybe you won't need to flash any modems. Likely, you may just be missing your APN settings. Check your APNs. If they're missing, google what they should be for ATT, and enter them. You'll want the wap.cingular one.

I have been around the forum for many years now, but am new to Android. I purchased a GT-i9100 in India for work travel between US and there. I have rooted and upgraded to 2.3.4, and applied a new kernel to remove the exclamation point. So, with that said, here is my question:
I am in the US right now, and in an area supported by T Mobile HSPA, but the phone will only connect to Edge. I am PRETTY sure it was only connecting to Edge before I did the work, but I cannot be sure. Would there be anything I did to the phone that would prevent it from getting onto the "4G" network? Is there anything I need to do now to change so it can connect?
I am not sure if this is related either, but I have a Verizon LTE data card, and if I place that SIM in the GT-i9100, it won't recognize it at all. It seems to only see T Mobile and ATT in the US.
I have spoken to T Mobile and they confirmed the 4g availability where I am, and they also reset my network connection, so the issue does not appear to be on my account or with TMobile.
Sorry for the long post, but I have been searching around and can't seem to get my small mind around resolution.
The SGS2 does not work with T-Mobile's 4G bands here in the US. If you want 4G you'll need AT&T.

That's because there is no resolution. As stated in several other threads on these forums (learn to do a search, and there's even one on the main page of Q/A right now) THERE IS NO WAY to get 3G on T-Mobile. The hardware in the phone does not support their 1700MHZ band.
Your 2 options:
1. Buy a T-Mobile phone
2. Switch to AT&T
Hi guys, I am about to receive a "new" refurb AT&T GSII to use on my T-mobile account. I have not yet received it, so forgive me if this is a stupid question, I just want to be ready for when I get it.
Will I be able to root the phone straight out of the box? I know I need to run the unlocker from the market, but need to root first. Is the phone "locked" like iPhones are out of the box? Thanks!
And also, can I ask what the number 1 recommended ROM is for this phone? I read CM7 has some issues, but are there any CM7 based ROMs that everyone loves?
No, I believe the phone works just fine without a simcard. You should be able to start up odin, flash CWM, and flash a rooted rom all without an active sim card. You can also setup the phone by connecting it to a WiFi network. Once unlocked it will work with your T-Mobile sim.
I don't think the att sgs2 has the radio to work on t-mobile's 3g bands. You'll be limited to edge speeds. If you are ok with that, you should be all set.

Yea, I have no data plan so I'm all good with the incompatible radio. Plus the screen/phone size on the I777 is perfect for me, while the Tmobile one is slightly too big.
I guess I will just follow the guides to root it. Now to pick the best kernel and ROM...
Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.
So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...
Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.
So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).
So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?
-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?
-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.
Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.
If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!
Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.
Reply with your findings.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."
:\
Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

Do all your entries match these? Write down your current ones before changing or take screen shots. You must use the menu key and save changes. Also make sure that is the APN checked after rebooting.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.
To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.
As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.
Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Thanks for the reply, was just wondering where you got a Korean note. hope you can figure it out and good luck.
Sent from my CM9 Note.
As the subject stated: I am planning to unlock my AT&T Galaxy Note to use it in Japan, but not sure if the Note will work there. I just want to be able to make calls and do light browsing at 3G speed (not 4G LTE)
Japan have 3G GSM network, so it should be, But want to confirm before I spent the $$$ unlocking my AT&T Note.
it has the proper frequencies for cellular use on 3g idont know about hspa+ so prbly dataspeeds around 2-5 mbps

Thank you for the information!
What kind of prepaid SIM are you going to use in Japan? I couldn't find any SIM that has prepaid voice and data together. So I'm planning to use b-mobile 1GB data plan with fusion IP phone SMART. That way, I can send/receive phone call and use data.
Did you have any luck? I can't get the bmobile sim to work with this phone. Urgent help needed. I suspect it takes some special config or different radio but I don't know. The bmobile instructions alone don't work.
Look up APN for bmobile. Just my 2 cents.

I had all the correct settings. I suspect the card did not work with Android 4.12. I have seen references online to rolling back to 4.11 for possibly unrelated or possibly related issues. They would not refund, so I had to do a charge-back on the card. Never trust a company who fails to stand behind a product when it completely fails to work. I ended up paying the higher price for AT&T which worked well except don't trust their wifi app - it tries to connect to partners who aren't partners, which disrupts the otherwise working mobile data connection.
Well, that really sucks, man. I guess your best shot would be to try and find another carrier that is GSM if the roll back to 4.1.1 doesnt work. Best of luck.
I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!

None of the codes work either:

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

My point, which you apparently missed, is that there is no reason for starting up yet another thread to ask questions that have already been answered. That''s why I said that this is redundant.
OK, let me answer your questions.
1. Can this be done?
Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
