[Q] T989 With AT&T GoPhone Coverage - T-Mobile Samsung Galaxy S II SGH-T989

I'm confused and I'm hoping for clarification. I've searched in the t989 forums and the skyrocket forums and come up with multiple conflicting answers.
Should someone using the T989 on AT&T GoPhone (prepay) bother flashing a skyrocket radio? From what I've gathered we don't have the hardware to get LTE bands so I don't see the point in flashing a skyrocket/at&t specific radio.
The reason I ask this i'm currently getting pretty decent coverage and up and down speeds with my phone an at&t sim and the at&t apn and setting network control wcdma to 850. Does the radio really matter? I'm thinking this configuration gives me basically the fastest connection I'm gonna see.
If anyone cares and if it makes any difference I'm running Jedi Jelly with the included LI1 radio.

ICS radios on Telus network with Dark side Evolution 2

I flashed Evolution 2 with no problems and followed the instructions to a tee. The only thing I haven't done is the cache wipe. The problem I am having so far is with the radio. I get no data and a data packet roaming message from the status bar. I can only get data working is if I flash the Telus modem prepped for ICS. I had similar problems as well with other roms and I'm guessing the radio rom that only plays nice with Telus is their modem. Am I wrong? If so any suggestions? I'm on the Telus network if it helps

Ok, first things first: do the cache wipe, and use the script provided with the ROM for it. Trust me, it won't delete any of your data, it's perfectly safe. (I speak from experience) The only thing you will notice is that your phone will take a really long time to boot immediately after the wipe. That's expected, let it be.
To your question:
It makes no sense to me why using TELUS' radio on TELUS should be the only way for your phone have data. I can't test this for you as I am not a TELUS client, but I have used the TELUS modem on Rogers and Mobilicity without any trouble at all. The one thing I can think of that may do this is your modem's band settings: the ROM comes with a modem for T-Mobile, which uses a different frequency for its data network. This is how you (try to) fix this:
Go into the Phone application and dial the following:
*#*#2263#*#*
Upon hitting the last * you will see the service menu for the phone, allowing you to set which bands the phone will be looking for for a network. Then press (3) for GSM and then (5) for GSM 850/1900. This should do it for TELUS. If this doesn't work, try using (3) for GSM and then (7) for GSM ALL, or if all else fails, just go into the menu and set (1) for full Automatic.
Another thing, though: I don't understand why you would want to use the T-Mobile radio, when the TELUS one gives you something all of us here can only wish for: presence on two networks at the same time. You can be riding an elevator or take your time in the parking lot without loosing data even for a second! This radio is meant for the TELUS network, and is giving you the best possible experience on it. If it works for you, my advise is to stick with it. The T-Mobile one isn't a step up for you.
Thank you for the detailed response. It is very appreciated. The reason I used the T Mobile modem was that it was the one provided in TDJ's link and I thought it might be more "compatible" with the T-Mobile leak. I didn't know about the advantage that the Telus modem provided. Could you explain what is meant by prescence on two networks? Either case the Telus modem has been very stable thus far and I think I'll keep using it for now.

Well, this flavour of the Galaxy S2 is not meant for TELUS. It is meant for T-Mobile, an AWS carrier. This phone cannot work very fast on TELUS as it does not support its data network fully. Worse still, last Q4 this phone was pitched against Rogers' LTE flavour of the S2, the Skyrocket, whose ICS leak we were running until recently. TELUS had to beef it up beyond the 14Mbps possible with HSPA so that it would compete.
So, they loaded it up with a state-of-the-art HSDPA radio, which allows it to aggregate signal from two HSPA towers to get its speed edge. I don't think this is done very often, if at all: it's quite remarkable TELUS did that. In a nutshell, your phone can sit on two cellular networks at the same time, the 850Mhz and the 1900Mhz one, and aggregate them to give you the theoretical 28Mbps. Still not LTE, but in the ballpark. You own a T989D, where the D stands for dual towers, and the 850Mhz band means you can stream music uninterrupted while walking into an elevator and then out again.
So that's it, in a nutshell. If I were on TELUS, I would be running this radio as well, up until the day I can replace it with another TELUS radio.
Hello,
For people having problems With the TMO Radio on Telus.
The Tmo radio sucks on Telus it will break Data connection, so use the Telus radio. But you can not flash over TMO ICS Rom with the Telus RIL files, it will break signal all together.
If you are already using a TMO ICS rom use one of the Telus radios in the Nexusmod thread with the system folder removed or remove the system folder before you flash the radio.
If your getting ready to flash an Ics rom and your on Telus radio, skip the flashing radio step. I hope that helps.
Though I heard rumors that the Telus radio doesnt quite work perfectly with the TMO leak
If we could use this thread for problems with Telus users using the leak that would be great
After flashing the Telus modem with the RIL file removed, ie installing the modem from the Nexus Mod thread in the dev section, this Rom has definitely more stable data connection. There are still some random drop outs but not as often as the TMo radios. Actually I have flashed many of the ICS leaks and there has, in my experience, data drop outs with any TMo modem on the Telus network. I'm very happy thus far with Evolution 2. There are occasionally some app crashes and camera glitches but overall nothing deal breaking. Amazing job on this ROM.

Do you think this could cause a phone force close with the Virgin Mobile network?
EDIT: Yep. That was the problem. Thank you guys so much, I've been stressing for days... The Telus radio fixed everything.
Working for me here. I'm not sure if my speeds are where they should be though, as in they seem to be half of what they should be. This leads me to think that the phone might only be seeing and connecting to one tower instead of two for the HSPA. My baseband shows up as Unknown too, so I'm not sure if that is a big deal or not.
I am a Telus user and to be honest found my quickest speeds with the Blaze ics modem, but I live in a rural area. I am trying the UVCL8 modem now and it is okay. I was getting some data roaming errors with this one, but it seems to have smoothed itself out. The Telus & Tmobile radios as I understand it are supposed to both supposed to support HSPA+ or a theoretical maximum of 42mpbs. I would confirm all of your apn settings and make sure they are all fine.

Bizarre. I just tried the Blaze modem and had extremely slow speeds on speedtest. Like 1 mpbs, whereas I had at least 10 with Telus' modem. It isn't like I was getting slow slow speeds or anything I guess. Just kind of strange.

unlocked t999 on att help?

I just sold my skyrocket and got a real good deal on an unlocked tmobile s3. I changed my apn and it is showing 3g but my speeds ar 150kbps at best. I did alot of research (i am not saying there is something out there i could have missed) but all i could find is people saying they are getting 4-5 mbps, but nothing about what they did to get them. Some people are saying they are flashing att radios and roms but then other people are saying not to do that. How do i get hspa speed, should i or can i flash att radios and roms?

[Q] Straight Talk ATT Sim on T989 - slower data than on I777?

First, let me say that I may have set this up wrong, so any advice is appreciated.
I purchase the ST GS2 (I777) att model (running 2.3.6 on UDLG1 build) which comes with a ST sim before I discovered the T989 for cheaper. Got the T989 and unlocked it using info here. Took the ST sim from the I777, put it in the T989 and configured APN using the same APN info from the I777 (wap.tracfone - different than APN for ST BYOD sim).
The swap and I777 APN settings worked for calls, text, mms and data at first I thought. But I noticed that data is slow and intermittent. The T989 shows the 3g icon but when I run speedtest I get either a network 7kps down/999kps up or network connection issues. If I take the sim out and put back in the I777, I get 5-6Mps down and 1.0-1.5Mps up and the H+ icon.
The T989 is on 4.0.4 running stock build IMM76D.UVLH1 and the radio is T989UVLE1 (for unlock). So I flashed different radios but not any real difference. I also tried the LI and LH radios and the one for the Galaxy Note posted in radio sticky without different results.
I also tried the ST BOYD apn settings att.mvno and I get calls but no data. No help from ST customer service as they only support buying the separate sim card. I don't have one or else I would have tried it. Just wanted to try phone out before getting sim card. I wouldn't want this same data issue if I bought the ST sim separately.
And ATT works better in my area for coverage than TM before anyone suggests getting the TM sim.
Any advice? Thanks in advance.
Just to make sure it was not just that one T989 phone I have. I tried it on another T989 today and same exact issue. I beleive the T989 has the radio for HSPA+ on ATT. Perhaps that band of not enabled in the rom. Could it be a sim card issue - not sure how that effects it?
OK. I think I answered by own questions by reading HoFo thread #1781748 (can't post link). There the OP posted that they deleted the proxy and then got faster speeds. Worked for me too. Now getting 5mbps down and 1 mbps up.
The phone icon says 3g, but I assume that is because it is a TM phone and the icons related to the band that TM uses for 4g, not Att.
I suppose I can live with the icon saying 3g but with H+ speeds. Not trying to start an argument over the fact that H+ is nto 4g or really just turbo 3g. Just glad I got my speeds up.
Had similar issue with my T989 .. Thanks a ton

[Q] How to enable LTE radio on Tmobile.

Im sure its been covered but i can not find a clear answer.... I live in Kansas city and as far as i can tell Tmobile LTE is running in parts of Kansas City. What radio or rom will support LTE? Or are we still waiting on an update from samsung to enable the radio? Iv tried a few NV tweaks to no success. Any ideas? Iv looked into the Att radios but as far as i can tell it will make no difference to me being able to use tmobile LTE.
I'm almost absolutely certain, that only Samsung/Tmobile can and will unlock LTE when its ready. So just wait, because Tmobile has their own testers, I'm pretty sure they don't need or want xda members using it and "affecting their results"

[Q] Simple Mobile with i747?

Looking at a getting an S3. My carrier is Simple Mobile. Curious as to whether I'd have better luck getting a T999 or i747. The coverage map for LTE on Tmobile includes just about everywhere where I spend any time. The T999 doesn't have LTE coverage, but does have HSDPA. Looks like this might not make much difference though given where I live. Here's a thread I started on the T999 board, but maybe more relevant here.
