[Q] How to get 3G/HSPDA Data on International Samsung Galaxy S3 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi I just recently bought an international Samsung Galaxy S3 and for some reason I can only get EDGE data on the phone. Under specs the phone says it supports 3G/HSPDA data. I have Simple Mobile and have set the APN to Simple Mobile and still only get EDGE. I have also noticed that when running a SpeedTest it says the closest server/tower to me is Whichita, Ka which is ridiculous because I'm in New York City. Can someone please tell me how to get 3G/HSPDA data on my phone. Thanks in advance!

[Q] Slow data speeds with telus and some other questions

Hey guys new to the nexus world. This is the first nexus phone I'm used to the galaxy series.
OK so I bought my nexus from a friend who was on bell. I'm with telus and first thing I noticed is it doesn't say 4g on it just H I don't know if thats normal another thing is that my data speeds went from 7-10mbps with galaxy s2x (sgh-t989d) to less than 1 with nexus? Radio related issue?
Is the 4g icon a carrier related issue as it is with the galaxy s2 phones. Also are there any carrier based firmware like galaxy or is it all the same with all nexus phones
Thanks in advance guys

The Nexus isn't a 4G phone, its HSPA+...which is why is shows "H+" instead of "4G".
As for your speeds, I get between about 5-8mbps (on average) on Rogers with mine. I used to be on Bell and always got crap speeds on their network with any phone I owned. That's one of the reasons I ditched them.

Thanks I figured as much with the 4G icon even thought telus says that it is a 4G phone that supports up to 14mbps. I'm guessing the 4G icons for the LTE version in the US.
Are there any dialer codes that let you select band? besides *#*#4636#*#* or maybe a telus radio?

Not really, but its easy enough to flash a new radio (assuming you are rooted and have CWM or ADB knowledge).

[Q] at&t 4g on unlocked tmobile galaxy s3??

I have a unlocked t mobile galaxy s3 I'm using on at&t network and I only get 3g but my download speeds are 4 to 5 mb. Which is pretty decent but I was wondering if there was a way to get AT&T 4g? Maybe it's my apn setting issue? Any tips.....
What data plan are you on (medianet/dumb phone, fauxG, LTE)? I've rarely had issues with my unlocked phones having the wrong APN on AT&T, but here are the APNs: medianet is wap.cingular, 4G/HSPA+ is phone, and 4G LTE is pta.
That's about what I get on medianet. I've got as high as 8Mbps on pta but it varies and it's never been consistent for me. 3-5Mbps is normal for my HSPA+ in my area (Olympia, WA). I get about the same speeds in southern CA and tended to get better speeds by 1-2Mbps in Austin, TX.
If you're asking if it's possible to get LTE on the T999, I have no idea. ;P The MSM8960 (S4 SoC in both phones) does support it natively but I don't know if it's possible to enable the LTE modem in software. You could try flashing an AT&T modem but I doubt it's that simple.
Ok maybe I'm wrong but isn't the t-mobile galaxy s3 the only one that didn't come lte equipped because t-mobile uses hspa+?

That is correct. It uses HSPA+ 42

Hey I have a question regarding this topic and the quote above. You listed the Apn's with its respective data plan:
1. wap.cingular = non-smartphone (i'll refrain myself from calling it a dumb phone plan lol).
2. Phone = 4G/H+
3. LTE = PTA
So I've just switched over from IPhone 4s > HTC One X > to now the Samsung Galaxy S3 (International unlocked version).
When I switched sims from iphone to one x, my data wouldnt work so they told me to get an LTE sim and give them the imei # of the ONE x. So i did that and everything was fine. They updated my account and i was receiving LTE on the phone with no issues.
NOW, with my galaxy, i just stuck the LTE sim in the phone and the phone defaulted to the cingular 410 apn. This is same as wap.cingular.
So here are my questions:
1. Would it be beneficial (from a performance/data speed standpoint) for me to call AT&T and tell them I'm back to a NON-LTE phone and have them change my account to a non-LTE account? And go through the process of changing my imei # in their system again also?
2. Since I'm actually on a smartphone unlimited (i did not take advantage of the $10/mo medianet) should I change my APN settings to "PHONE" and not use what the S3 defaulted me to?
3. Whats the actual difference in using wap vs phone APN's... I know the settings themselves are different, but anybody know the technical differences?
Thanks so much in advance!
T-mobile galaxy S3 on ATT 4G network
Hello can anyone post pics of the Galaxy S3 (T999) the t mobile version on ATT 3g or 4g networks. I am thinking about buying it but wanna be sure that it works before i spend the big bucks
This guy confirmed it works:
http://forum.xda-developers.com/showpost.php?p=27984139&postcount=28
Anyone else have such luck?
I'm having this exact problem. I have an unlocked T Mobile S3 that I want to use on the AT&T network. Phone, text and VM work fine although AT&T hasn't figured out how to give me data service in any form. They're all stumped by this.
What I really need help with is coaching AT&T through the process.

No Data on AT&T for unlocked T-Mobile N2

Hey all, been lurking for a while and found that many of you have unlocked Note 2's running on AT&T. I bought my unlock code and all is well on the voice front, I just can't seem to get data working (not edge, not 3G, not HSPA+, nothing). I've tried the various APN's floating around, I've tried selecting CDMA ALL for the frequency band, and I've selected AT&T and "registered on the network" using the automated feature of the phone itself. Still nothing.
When the AT&T version is released, will I be able to flash the ROM and make it work as if I bought it from them?
Thanks in advance for your help.
Thats weird. I unlocked mine and got tge cingular apn automatically .

Do you have the right sim and have you got at&t to update their system so it can work? Tell them you have a Note 1.
That's what Indie. I have data (but not LTE)

This is the answer I needed. Thank you! I ended up going to the AT&T store today. They said that for some reason I didn't have a data plan anymore (weird because I traded my iPhone 5 for this phone! They subsidized it.) They couldn't get my IMEI to work in their system so the saleswoman used her own IMEI to get me going.
I had been to the AT&T Store once before to trade my nanosim for a microsim, but the phone wasn't unlocked at the time so I couldn't test it out. They scanned in my phone but I guess it didn't take. All is well now, I have 4G (but not LTE, but it doesn't matter because I'm moving to a non-LTE city in less than a month).
It works perfectly, I put in the APNs from the Galaxy S3 on display that the AT&T Store. Decent speeds, awesome phone. Thanks everyone!

I wonder what speed you can get on att 4G network with TMO phone if you have tested, one of my buddy has a international version he gets 3 - 6 when did a speed test

That's what I get. And honestly, 3-6Mb/s is perfectly fine for me. I'd like to get LTE for the time I'm here but it doesn't bother me that I don't. At some point one has to question that value of 100Mb internet on a 3GB data plan.
LTE is locked as of right now on the tmobile GN2

I know it isn't AT&T but it took a while to get Solavei APN working on my phone. I played with the settings forever with a customer service rep before I finally got it to work. MMS & internet work great now! Can't wait for LTE to launch!
i got my tmo verion unlocked. I purchased a 50/mo at&t go prepaid, and I can see 4G in the status bar.
Hope this helps

[Q] How to turn off 4g LTE on AT&T Note II?

Hello,
I am a new android user and made a switch from apple to get the Note II. I wanted to know if there was a way to turn off the 4G LTE and just switch over to regular 3G? The reason I am asking this is because none of the areas where I live have 4G service and we just recently got 3G service with at&t earlier this year.
So if anyone could help me out with this, I would really appreciate it.
Regards

[Q] Note 2 dilemma need feedback

Hello everyone,
I am having a serious crisis. So let me give you a little back story. I previously had a unlocked gnex and I had been using it with straight talk att and simple mobile. My particular phone didn't like straight talk at all I was always having data problems and the reception and data were very slow. Simple mobile worked great and very fast and the soft data cap I found was a lot higher than att's. I sold my gnex a few weeks ago before the nexus 4 launch so I could get more money for it. I have been using a Nokia E5-00 in the mean time on straight talk and fr some reason it has been great way better reception and the data is actually faster than what I was getting on my gnex even though this phone only supports hspa+7.5 instead f the full hspa+21 the gnex had. I really want a Galaxy Note 2, but I have been hesitant of ATT's network and I am afraid I will have the same roblems as I had with my gnex. So I wanted the T-mobile version because it would give me the flexibility to switch between the above listed carriers and since prepaid doesn't have lte support I could get the hspa+42 and know I will get faster data than ATT. I have to get the phone from amazon, long story but that is where I have to get it, they dont seem to be getting the t-mo version anytime soon and everywhere is on back order, but I cant deal with using this E5 any longer. I can get a ATT Galaxy note 2 and they just turned on LTE where I live in Columbus, Ohio. I had 2 questions I hope somebody can help me out with, since I am using prepaid and wont get LTE is there a hack to make the LTE work? Also is the HSPA+ on ATT going to provide faster speeds than before now that LTE has launched relieving some strain on hspa+ and providing more back-haul to the sites? Any incite would be gratefully apreciated
