Everything seems to work relatively well with my current unlocked device on ATT. Only problem is data seems kind of patchy (speedtests show it just spiking and dropping like mad, have to hit retry frequently when loading pages or surfing the app store, etc). I am using the ATT APN settings based around the wap.cingular stuff that seems to be the most common. I average around 1mb speeds so my question is would I benefit from finding a different radio for this setup? If so which one should I try?
Device is running the Darkside venom ICS build. Thanks.

I plan on going to a straighttalk sim. Which would be off att (that's the sim I want) and I'm going to keep the ice cream sandwich kernel on it ulve1 I believe it is. I would NOT flash an att radio. I believe that would brick it.

I guess i'll just keep on cruising along. It seems to work alright but if there was a way to squeeze more power out of this bad boy I'd certainly take it.

False, you can interchange between SR and herc radios kernels and roms. Just don't odin anything.
Btw to op. Sell your herc and buy a SR for cheaper + using LTE = profitx2

I didn't think the ST plans supported LTE, so SR on ST isn't any benefit over the T989?
To the OP, you might check out here:

OK, why do folks have an interest in flashing skyrocket stuff onto the T989? Just get a carrier unlock from TMO, get an ATT or ST ATT sim, and pop it into the T989, talk away. What am I missing? What does the SR have that the T989 doesn't?

For faster data and stronger signal you want an att radio which is design to optimize those bands.
SR has LTE. other than that they're identical

its ymmv, the stock radio can pick up H+ on AT&T but for users who have slow data, flashing AT&T radios helps. Unless you're just trying to prove me wrong or something.

Trying to find some data. Something like "on att with tmo radio I get 2 MbS download, but same phone on att with att radio I get 4mbs".
I know that different combinations of radios and roms can improve reception in some areas.
I also haven't seen anything that indicates the MAGNITUDE of the difference.
I get that sometimes, maybe, if you're having trouble with your current reception, you might be able to get better reception if you flash some other radio. (from your current carrier or a different carrier)
BUT some folks think that they should almost routinely flash their T989 to an att radio if they want to use it on ATT. I haven't seen it help at all on my phone.
So my question is two fold, what is the MAGNITUDE of the difference, and, how OFTEN does it make a difference. I was hoping someone had some data on that.
Thanks!
Hello,
So im having a bit of an issue and hoping someone can help. I gave an unlocked galaxy s2 t989d to a friend in the us to use on att. Data was not working so i entered the correct apn values and it works great. For some reason though, the phone jumps onto the tmobile network randomly sometimes even while in an att service area.
So my question, is there any way to stop it from going to tmobile? I want it to stay on att.
Thanks for any help!

Does it happen in any area or typically their home area? It could be several factors that cause this...is the phone rooted?
sent from my T989 full of CM awesomeness and a touch of Venom from the Darkside!!
It happens when she is at home. She has weak signal in her basement and the data drops down to edge. It then will briefly jump over to tmobile and say roaming then go back to att.
Any ideas?

well she's in a basement first and foremost, some basements can cause that. Thats normal, if the signal coming into the home isn't that strong in that area of the house, then thats normal and in reality there isn't much you can do about that. However, you can try to flash a different radio. I've heard good things about the blaze 4g radio (uvlf4) in some areas, and the galaxy notes radio (uvlg3) for others. I personally get the best signal off of uvle1 (tmo ics radio). Try those other two out and see if it improves. But if its only that one area, then that could be the culprit, and that unfortunately is something nobody can really do anything about. I had an apartment that was like that once, couldn't get anything useful out of my cell unless i was on wifi.
worse case scenario she can install a home repeater for AWS 1700/2100
http://www.wilsonelectronics.com/ProductDetails.aspx?Product=155&title=AWS+70+(802365)&Category=11
it has been tested and it really works, luckily i have no needs for that, but I've always planned to install one for my Car when i drive to poor reception areas
Thanks for the help!
I will try flashing a new radio when i grt the chance and see if that helps. I figured it was just an issue because of the low reception. I just did not want her to incur any roaming charges or anything so i figured i would see if someone had an idea.

Ok SO I could not find a proper thread for this since there are SO many threads. The issue I'm having is I got a Samsung galaxy S III that was unlocked, and after I put my ATT sim into it I could recieve texts and calls but I could not recieve data. So I rooted it and applied clockwork with all my mods and figured I could find some setting that would fix it... well I was wrong. I tried global, GSM and LTE settings none of which would give me data. If there is anything anyone can do to help I would be more than appreciative.

Ok so this is a verizon Galaxy S3. It is rooted running 4.1.2 JB, Kernal 3.0.31. After I got the phone I did go to an ATT store to register a micro sim because i didn't have one at the time.

You do realize you're trying to use a cdma phone (verizon) on a gsm network (at&t), right? Different radios. Different technology. Won't work
Well it was unlocked at the phone has a gsm option so if it wasn't compatable I don't see why they would have the option there to actually use a gsm network.

You need to read more.
this phone only supports GSM with EDGE data.* This essentially means that you'll get 2G data speeds (unless you have a WiFi connection) because it doesn't support UMTS/HSPA+ which is required for international and U.S. 3G data. the 4G LTE frequency supported by this phone is only used in the U.S.* For those who don't know UMTS/HSPA+ is the 3G technology used by GSM carriers internationally (and used by AT&T and T-Mobile in the U.S.) which is different from the CDMA/EV-DO 3G technology used by Verizon and Sprint.*
This phone IS unlocked, that part is correct. But only for gsm carriers
So its preventing me from recieving ANY form of data possible?? It is a Verizon phone and I have ATT so you mean it doesn't support GSM then right?

You're in an at&t s3 forum with a verizon s3 that has zero data. If you really want to pursue this issue, you should start looking around in the Verizon S3 forums

If you are going to stick with AT&T, that is the way to go if you want to have data. No worries. Stupidity is only if you didn't learn anything. You had ignorance of the situation and now your don't. Do some research on any phone before you buy next time (especially if branded from another carrier). This can save you a lot of headaches as you have just learned. Just remember some basics from this forum. Good luck.
Have an AT&T i317 unlocked with a T-mobile data sim.
I've done the tweak to enable the 3G/4G bands, a la http://forum.xda-developers.com/showthread.php?t=2068041
But now T-mobile added LTE in a few markets. I drove through one and suddenly got no data access. This is with "preferred network mode" set to LTE/WCDMA. If I switch to GSM/WCDMA, all is well (it sticks to the HSUPA and H+). So clearly it thinks it's on LTE but the phone can't access the T-mobile LTE.
I'm using Cyanogenmod 10.1, android 4.2.2, which also makes the model number show GT-N7105 instead of i317.
any tweaks to add the LTE? do i need to dump CM and use a diff ROM? do i need to go back to stock first to do any of this? (Right now, I can no longer dial *#7284#)
Thanks!
I am having a similar issue, I have a sgh-i317 with aws mod and the phone is not picking up t mobile lte even when placed next to a sgh-t889 that is getting it. Lte works with att sim but not working with tmobile sim. Any help would be great. I have tried many roms and modems and reflashing aws mod. Roms inculde jedimaster13/14 jedi x13/14 both att and tmobile versions and clean rom and stock 411 and stock 412

Does the AT&T version have LTE? If it doesn't have the capability, but he modem is telling it to access it when it sees it, that might be why it dropped out completely. I'm mostly curious to see if AT&T LTE devices can use t-mobile's LTE network because I want to get an s4 active and I don't want to lose LTE by making that switch.
Try this for me, instead of that model number you have. Change it to the T-Mobile model#. Which is going to have to b done thru the build prop. Then reboot. Then go try and c if you pick up lte.
Because I just flashed a AT&T Rom on a T-Mobile GN2. And I pick up lte just fine with my AT&T SIM in there! And no AWS MOD what so ever. But the MODEM is still TMO, it'll always b TMO. Flash a att modem on a TMO GN2. Brick city.
Let me know what happens just curious!!
Edit: the Rom I flashed was SKY NOTE 9. No modem included!!!

WELL, here's your answer.
Maybe they getting the device at a cheaper price. Which would make someone but it. Instead of spending a lot more to have have the carrier brand you need. FYI
Both the phones are exactly the same. Besides the model# and done bloat. Like I said above, if it's unlocked it'll work, with both carrier's. So why not have that option to switch... and one more thing being able to take the phone internationally, and pop a SIM inside and ya have service. No roaming !!!
Just my 2¢® 2 you're question...

When a t-mobile version is available, I do buy it, but with ATT exclusives, that's not an option. For instance, I want the s4 active for its water resistance. T-mobile will soon offer the xperia Z, but when you compare the features and perormance, the s4 active is better, so for the money i'm willing to spend on a smartphone, i'd rather have the s4 active.. the hardware is capable of t-mobile LTE, but it still has to be configured properly with firmware and software to use the radios correctly. Since radios are some of the hardest pieces of firmware to alter, it's worth doing this investigation / collaborating to find work-arounds.
I didn't get tmobile lte on my at&t note 2 until I flashed the new at&t radio. That's all that had to be done. I'm using Skynote9 too. I did the aws mod again so I could get h+ 4g speed enabled and now is a flawless tmobile phone. Let me know if it works for you.

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?
Maybe you should try posting in the ATT S3 forums? I'm pretty sure that most people here have the TMO variant, while you are looking for tweaking of the ATT variant.

Don't flash a T-Mobile modem, it will brick. T-Mobile and AT&T use different frequencies for hspa+ in most places, and the AT&T version doesn't have the hardware to pick up the most used T-Mobile frequency I believe. So you're probably stuck with edge

You ARE stuck on edge.... I know it sucks. unless you are in a refarming area http://www.airportal.de/ , (major cities) your AT&T S3 1900/2100Mhz high speed data (4G) band will not work on T-Mobile's 1700/2100Mhz networks.
