Are both boxes for data checked? Have you rebooted? Did you flash a kernel?

I have no idea. But a guess would be due to the fact the iPhone SIM is not an LTE SIM. AKA, not compatible with your phone.

Yes need a new sim card. If not in LTE area you can use the HSDPA APN and get 3g speeds.

Sim won't matter, if your coming from an iPhone and didn't change your plan changes are if you look on your s3 its trying to use PTA but you aren't setup for it yet. If you change it to WAP or PHONE it should work or call att change your plan then PTA will work

The answer to this question is simple...and you could have easily searched to find the answer....iphone needs iphone data plan gs3 needs lte data plan...the mini sim is standard...there isnt a special iphone sim etc....next time try searching.....

Call at&t and tell them to switch you to a lte plan. Done.

Ah, makes sense. I thought it would at least get 3G service but i guess not. No worries. Ill call them today.

You should be getting at least 3g. Check your apn settings.

How about even simpler .. if phones are locked.. ATT locks phones to sim card and it won't work with a different one unless you unlock it.

You DO need a new sim card. This happened to my friend a few days ago.

IPhone and androids use a different data plan. You need to get switched to an android data plan.
Sent from my SAMSUNG-SGH-I747 using xda premium

If your sim is blue and white, you need a new one. If it's orange, your fine. Just call and have them switch you from the I phone data to the lte data plan.

Carrier unlock

Carrier unlock for the GN2. I did it but haven't a SIM card to test it yet. Can anyone confirm that it work ?
http://forum.xda-developers.com/showthread.php?t=2014982

Repeat thread; it works, many have confirmed it to work on their AT&T and T-Mobile Note 2 handsets

I just called Tmobile and asked them to get the unlock code for my GN2 and they gave it to me no questions asked. Free!

Please define 4G data speed. What download speeds do you get using Ookla or speedtest apps?

In Atlanta I get at 10 down minimum and a high of 19 down when super close to a tower. And yes, this is all marketing. 4G means 100 down. But our phones work good. Who cares?

Getting HSPA speeds on AT&T

Ive searched many threads but cant find an answer. I carrier unlocked my T Mobile Note 2 and use it with AT&T. I see many people have done this but those people get at least 3G speeds. Im getting Edge only speeds. I added the APN wap.cingular and tried the PTA one. PTA doesnt work and wap.cingular is how I get edge speeds. What can I do?
Sent from my SGH-T889 using xda app-developers app

You'll need to install an ATT compatible radio to get 3g. I don't even know if one exists, but I'd try googling something like "use T-Mobile note 2 on AT&T" or something like that.

That is not accurate.
I have a T889 that is unlocked. When I put my AT&T SIM card into it, I get 3G speeds comparable to my regular AT&T devices.
I didn't do any kind of modem flashing or other tweaks. I might have had to enter the proper APN settings, it's been sb while so I don't recall for sure, but I know for a fact that nothing else was needed.

Can you check your APN settings for me Im not getting anything but Edge speeds and its driving me nuts

The ROM I'm using (based off an international Note 2) seems to have AT&T APN settings built into it, but they seem similar to one's I've input manually when on the stock ROM.
I just shoved my AT&T SIM into the phone and confirmed HSPA+ service being received, although it's a pitiful 3 Mb/s around here. That's the same I got on my One X with the same SIM just before putting it in the Note 2 to get you these settings.
Here's some screenshots for you to coy the APN settings from.
Sent from my SGH-T889 using Tapatalk 2

if you use dialer code *#*#4636#*#* .. can you access the pop-up menu? You can enable LTE/UMTS in this section...

Same Problem
I just went to AT&T to get a new micro sim, called cust service to change my imei ( though not the actual international one ) to make sure I'm on the right plan, but after testing the phone and PTA APNs I'm still only getting Edge speeds ..if anyone can help that would be great!

Which SIM did you get t-mobile or at&t?
Sent from my LG-P930 using xda app-developers app

If you got a T-Mobile Sim, you're not only gonna get 2G I think which would explain the slow speeds.

its an ATT sim so I dont know whats up.

Its probably your apn settings. Make sure proxy and port are blank. ST's recommended apn settings will limit your data speed. BTW make sure you still have recommended setting for MMS proxy and MMS port.

I put my wifes ST sim in and i got 6mb transfer rate, so im calling ST. I def have not used a lot of bandwidth so i dont think im being throttled.

UPDATE: I called straight talk. They reset my internet settings on the account. They called it a 'congestion'. Either that or they were randomly throttling people to see if they notice. Anyway she did that then I rebooted my phone and get a solid 6mbps download connection and about 1 up. So that seems to have fixed the problem! They were pretty easy to deal with.

Glad to hear you got that figured out

I been with straight talk for 26 days first three days was fast after that I was getting 3 to 10 k I call straight talk they told me something about section 6/7
I told them I did a hard reset and download my apps and still getting 5 to 20 now

Yeah I'm cool not having lte until it's released but how does my sgs2 get better speeds on t mobile?
Sent from my GT-N8013 using Tapatalk HD

Honestly I'm thinking some of the issues are the build.prop
Ive been adding a few things ril related
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=9
ro.ril.hsxpa=5
ro.ril.gprsclass=12
And getting somewhat better performance though I'm not certain they are helping I don't have the energy to check if something else is setting them

Just add a new APN with epc.tmobile.com, the new APN (fast.t-mobile.com)on the 4.1.2 is the one making you get the slow speed.

the new APN is for the LTE network supposedly. Not sure if it will be only for LTE or if you'll be able to epc for LTE as well.
I'm in one of the LTE markets and keep flipping between stock and carbon rom. Tried cyanogen and have had the best luck.
I bought my note 2 at full retail for use on prepaid 70$ plan to see if I want to switch off my VZW unlimited data with 30$ hotspot.
I'm anxiously awaiting LTE turn up!

They cover how to make the APNs editable in these forums you'll have to search. I don't have the energy to look at the moment.
Edit:
Ended up finding a decent example of editing stock with new APN.

I thing they are testing LTE under fast.t-mobile.com but if you live in a tmobile LTE area is no need to change to epc but if you see slow speed have the epc apn available to switch for faster HSPA+.
Sent from my SGH-T889 using xda app-developers app

Yeah I think they are using it to test also but that's a guess. I constantly switch between 3g and 4g icons all day. ... Like every ten seconds when in most areas. I'll leave apn until tomorrow and then switch to epc if I don't see lte. I live in Miami fl and have been checking downtown in hopes of getting lte
