[Q] - T989 on ATT network

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

Not according to mr vlad.. which makes sense cause of LTE. Plus for me i cant get anybodys LTE where i live.
Unless the Herc ignores the LTE frequencies using that radio?

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:

Folks are posting tmo and att ST speeds. There's an off chance someone from your area may have posted att speeds for you to compare to.

But one can still flash an att radio and the Hercules would ignore the lte? Or would flashing a sr radio brick the device?

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?

Brick the device, they're interchangeable. Herc does not ignore lte. They don't even pick it up.

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!

Help with mobile network

I have recently flashed my phone from stock GB to aokp JB. The fone works great and would like to thank all the people who posted in here and got me up and running. My problem is that after i flashed i dont see tmobile as a network anymore. I only see att as a service provider. I have a tmobile sim card installed. i can make phone calls and data is fine but sometimes when i go underground and lose service my fone acts funny. For example phone.com fail. or i'll lose wifi...

Data issue...

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.

While I agree that you should always call at&t so they can register a device to your account, this will not help his current data issue
OP, is this an international s3, T-Mobile or at&t? What firmware/rom is installed? Again, verify your imei is intact

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. So the imei is registered to my sim card perfectly. I can get calls and texts without any issue but no data. How do I figure out what the apn settings are and if I have the right configuration?

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 I'm not mistaken, some Verizon devices will not work on US gsm networks even if unlocked, only foreign gsm networks.

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.

[Q] Flasing T-Mobile roms on AT&T GS3, getprop error

I have a Galaxy S III from AT&T. I got it unlocked and activated on T-Mobile last month.
Now, I went a month on AT&T roms, but recently I flashed SlimBean, which is dual carrier. My phone immediately connected to LTE! Never had I seen LTE on TM's network on this phone before, so I take that to mean I need to run T-Mobile ROMs to get LTE service.
So just now I tried to flash BeanStalk for d2tmo, but it won't let me install it because, of course, it's not made for this phone. From what I have read, though, it should work fine on my phone. How do I override this failsafe so I can run T-Mobile roms on my AT&T gs3?

"You do this with 7-Zip/WinRAR
Note: DO NOT EXTRACT ROM!
Open the zip file, do not extract, go to:
/META-INF/com/google/android/updater-script
1)Open updater-script with a script editor such as notepad/notepad++ (makes things 10x easier), or gedit if you use linux
2)Delete the first line of code (all the way up to the first semicolon you see) and delete the first semi-colon as well
Do not go past the first semiclon when deleteing and DO NOT forget to delete the first semicolon."

You'll want to delete the highlighted text in the updater-script, then save it. You shouldn't run into anymore problems or errors when flashing the ROM.

Well I had LTE / GSM / WCDMA selected in the settings on CyanogenMod for the I747 and it wasn't connecting to LTE. Only HSPA+. So either it's the ROM, or T-Mobile launched their LTE network here at the same time I flashed SlimBean.

I'm running stock i747 and I get Lte all over Chicagoland. I'm rooted now, but I got it before I rooted too. I'm using the stock 4.1.1 that came with the phone, picked it up for $180 a few days ago...Wow this thing is awesome.
Thinking about going with Dandroid tomorrow...still deciding att or T-Mobile version.

Please do let me know! When I was running the AT&T roms, I had "Simple Mobile", "StraightTalk", and "T-Mobile". I tested and all of them worked, but just connected to HSPA+.
Now that I've installed a T-Mobile rom I am also getting "Solavei" and "T-Mobile LTE." When I select T-Mobile LTE, my phone connects to the LTE network. When I have the regular T-Mobile option selected it doesn't connect to data at all.
EDIT: I am testing again, and I actually can connect to HSPA+ on the regular T-Mobile APN. Let me walk around and see if I can make it connect to LTE. Then I'm going to flash an AT&T rom and try to get it to connect to the LTE network by manually adding the APN. I'll let you know how it goes.
Can the APNs determine what type of network you connect to?
I'm just curious what APN settings you're using to connect to LTE on the AT&T rom.

Okay, here's another update as the result of some testing with my T-Mobile rom:
When I switch to the "T-Mobile US" (no LTE) APN, I noticed that my data cut in and out sort of randomly. I speculate that the reason for this is because it was trying to connect to the LTE network but couldn't get data on it because my APN was set incorrectly. This is what confused be before. I switched the data mode to GSM / WCDMA preferred and it immediately connected to data, and was consistent.
So I think if I just add the T-Mobile US LTE APN to an AT&T rom, it should connect to LTE properly?
A long time ago when I was just on the T-Mobile US APN on an AT&T rom, it was doing the same thing with being inconsistent with the data connection until I disabled LTE so it stopped trying to connect. I'll take the fact that it tried to connect but couldn't as enough evidence that it knows how, it just needs the APN.
Yay figuring things out! Sorry if my words are confusing or I maybe I should have made a new thread for this. I'm new here, and I'm not sure how this kind of things work.
Thanks for the help in figuring that out!
Sorry about the sidetrack, I'll work on getting 4.3 next, and let you know how that goes.

[Q] At&t S3 On MetroPCS LTE/TmobileLTE

Hi guys, i have a s3 i747 that has been unlocked and ready to be used on other gsm networks.
I went to a metropcs store and had the phone activated and sim card inserted, my imei was connected fine and everything went great.
I instantly had EDGE(1x or 2g) and even after hours of searching and phone calls to metropcs all i can find is APN solutions that dont work.
I currently live in Dallas/Ft Worth so i know the LTE coverage for Metropcs/Tmo is amazing it just ill not connect to LTE.
How do i get LTE to work on this device ??
Phone Specs
Has root
Unlocked
S3 i747 from At&t
Worked fine on At&T for LTE
Su keeps for closing at start because it says security issues
Stock rom on 4.3 but it says custom build under about settings for some reason.
Data speed is about 0.09-0.10mbps
Any help would be great. Sorry if this is a repost of other types of threads but i never found answers and did not want to re awaken old threads.

This issue seems popular this week.
If it's like the others, it's an issue from unlocking. the nv file gets damaged. The solution so far is to use nv-reader-writer to copy another phone's nv file and replace yours with it.

have you tested *#*#4636#*#* method? just mess around with the preferred network and see
I'm on Tmobile and worked fine with LTE

Where could i find a nv file for the s3 i747?

You do realize 4g and LTE are the same thing?

Sir, i tried to use the nv tool but it keeps saying phone wont connect.
i have the drivers installed, it sees my ports for the phone, i go to connect and it does, but when i click read device it fails. Ive had no boxes checked, one box checked and both boxes for spc and fast read(i think it is) checked. No Go either way. Any suggestions for this? Then i can see if the NV Writer is a solution. Also i can use my own NV file right??? Or would that just be a corrupted file being reloaded ?? If thats the case how do i find a clean NV file for a Samsung Galaxy S3 i747 for AT&T??? Thanks again for the help brother

I would think you would need to load an NV of a different s3. I will try to load my NV here in a few and see what happens. PM me also

Ok guys i tried some settings. a guy i know tried to inject the AWS for Tmobiles band freq. and it didnt work.
SOooooooooo im thinking we might have to skip AT&T phones on metro/tmo and get a tmo phone or a AT&T phone that supports AWS band freq.

Wait....How are you getting 4g ?? it might not be LTE but da*m its faster than Edge. Could you tell me your apn, and your settings if you changed anything since you first switched to metropcs.
Like dial star, hash(number sign)twice, the 4636 and star,hash star, hash and go to device info, then screen shot, then scroll down and screen shot again where i can see "set preferred network"
also man are you sure you have the S3 I747 from AT&T??

Make sure you are checking your connection in Settings > About Device > Status > Network Type
You cant always trust what's displayed in the status bar. Especially when using a custom rom or using a device on a different network than it was intended for.

Yea man I know. I've checked everything and says edge still.
I think it's based on your radio and kernel. Brad what kernel and radio you using.?
I'm on 4.3 Rooted and stock.
